The use of wood as a primary building material has been part of our architectural identity for centuries. At KAGER HIŠA, we continue this tradition with a forward-thinking approach—one that blends natural materials with modern technologies and refined architectural design.

From tradition to modernity

Today’s architectural solutions often draw inspiration from the past. Timber-frame construction is one such method that is regaining a central role. While it was widely used for centuries in regions north of the Alps, it was gradually replaced by brick and concrete construction in the 20th century. Due to low ceilings, small windows, and poor energy efficiency, wooden houses were long seen as outdated and were pushed to the margins of contemporary design thinking.

But that perception is changing.

Thanks to technological advancements and a renewed understanding of living in harmony with nature, timber construction is once again becoming synonymous with progressive, open, and sustainable architecture. Today, this approach is combined with advanced technical solutions — and in the case of KAGER homes, also with a distinctive architectural aesthetic that merges glass and hand-crafted wood.

The result: homes that combine open layouts, natural light, and timeless structural logic.

A supporting frame that creates freedom

Many effective architectural principles are rooted in nature. This is also true of timber-frame construction, which functions much like the human skeleton: a self-supporting structure that carries the entire load and thus allows complete freedom in spatial design.

This system is the foundation of KAGER’s modern architectural approach. It is not merely a technical solution — it is the starting point for designing homes that are open, filled with light, connected to nature, and tailored to contemporary living needs.

Architects value the flexibility of this construction method, as it allows for varied floor plans, expansive glass surfaces, and scalable buildings of different sizes. Wherever these homes are built, their timber structure and thoughtful design naturally integrate with the surroundings. The architecture is not imposed — it responds to the environment and the needs of those who live within it.

More design freedom, more living space

Homes built with timber frames offer an immediate sense of warmth and comfort. Wood creates a calm and natural atmosphere, which is further enhanced by large glass openings and open spatial layouts. In this kind of architecture, the connection between the interior and the outdoors is seamless: natural light floods the space, while views open out toward gardens, forests, or the wider landscape.

Timber-frame designs allow for large spans without interior walls or columns. This grants freedom in creating flexible floor plans, dynamic volumes, and architectural solutions that are often unattainable with traditional masonry construction.

It is precisely this structural flexibility that enables the home to fully adapt to its location, to the architectural concept, and to the lifestyle of its inhabitants.

Speed rooted in precision

Building with a wooden structural frame, manufactured under controlled conditions, allows for exceptionally fast on-site progress. The key components — from the structural skeleton to the wall elements — are pre-fabricated in our own production facility in Ptuj, Slovenia.

Each element is designed and crafted with millimetre precision, ensuring a reliable and time-efficient assembly process. On-site installation takes just a few days, free from weather-related risks or unnecessary delays.

All project phases — from design and production to final assembly — are managed by experienced, highly trained teams, ensuring that the finished result meets the highest quality standards down to the smallest detail.

Sustainability through timber construction

In recent years, growing environmental awareness and climate responsibility have renewed interest in building with wood. As a renewable material, timber has a significantly lower environmental impact compared to concrete or steel. Simply choosing wood as the primary construction material can greatly reduce the building’s overall carbon footprint.

Beyond its ecological advantages, wood also has a natural thermal insulation capacity. When combined with advanced systems such as triple glazing and a well-designed building envelope, it results in low energy consumption — both in winter and summer.

The outcome is a home that is energy-efficient, sustainable, and built for long-term performance — without compromising on living comfort.

Structural stability and safety with timber

Open floor plans, large spans, and extensive glazing do not need to come at the cost of structural safety — quite the opposite. A thoughtfully engineered wooden frame offers architectural freedom while ensuring high structural stability.

KAGER houses are built using high-quality, technically dried structural timber (e.g., glued laminated timber or BSH), known for its dimensional stability and mechanical strength. Precisely crafted joints and a well-considered structural system ensure even load distribution, even across large spans or multi-level homes.

Thanks to the elasticity and high load-bearing capacity of wood, these structures are particularly resilient to natural forces such as earthquakes and strong winds — in many cases outperforming traditional masonry construction.

Safety and stability are therefore fully integrated into the design, without sacrificing architectural elegance or everyday comfort.

Nineteen years ago, prefabricated wooden houses were far from common—especially those with a visible timber frame. Skepticism was widespread. Would such a structure be strong enough? How durable is wood, and how much maintenance does it need? Can glass really withstand the test of time?

Today, those doubts are long gone. This home stands as living proof that a well-built timber-frame structure not only endures but ages beautifully.

A dream home among the vineyards

The family from Maribor dreamed of a brighter, more peaceful home surrounded by nature. Their former weekend retreat on the city’s edge was replaced by a natural, light-filled and spacious Vita Nova — a home that continues to impress with its architecture and warmth of wood.

Because of the steep terrain, months of coordination with builders were needed to complete the concrete basement. The weather didn’t make it easy — heavy rain caused delays. Yet, on the morning when the KAGER delivery trucks arrived, the sun broke through, and within days the family watched their new home rise into place.

Years later, when we spoke with the owners about their experience, they summed it up beautifully:

“If you feel comfortable in your house every single day, it gives you warmth. And if others feel it too when they visit, you know you’ve won. Because then you can truly say — this isn’t just my house, it’s my home.”

Today, the children have grown and moved out, but the house among the vineyards remains the heart of family gatherings. Birthdays, holidays, and weekends still bring everyone together — and when summer returns, the grandchildren eagerly take over the pool and garden once again.

Wood that defies time

After nearly two decades, the house still shines with the same charm as the day it was built. The visible timber structure has been carefully maintained — refreshed every few years, preserving its natural tone, texture, and character.

Recently, the family decided to renovate their outdoor terrace with Kerowood bamboo decking, a natural material known for its strength, resilience, and refined look. The new system was installed around the pool, terrace, and balcony, creating perfect harmony between the façade, details, and outdoor living space.

These thoughtful updates prove that timeless architecture can be renewed without losing its identity — it simply grows with those who live within it.

Architecture That Stands the Test of Time

Nineteen years on, the home demonstrates that the lifespan of prefabricated timber construction is fully comparable to traditional masonry. One of the most common misconceptions about wooden houses is that wood and glass lack durability. In reality, precision manufacturing and the use of certified BSH laminated timber ensure exceptional stability and longevity.

Wood, as a living material, naturally regulates humidity and breathes with its surroundings, maintaining a stable, healthy indoor climate even after two decades.

The Vita Nova skeleton system allows flexible reconfiguration of space. Now that their children have moved out, the owners could easily adapt the layout if needed — without major structural changes. The home continues to evolve seamlessly with their lifestyle.

And even after all these years, our KAGER service support remains available. From maintenance advice to post-warranty services, every KAGER homeowner can rely on expert care whenever needed.

This enduring relationship proves that true quality is not defined by the moment a house is built — but by how well it continues to serve, year after year.

At KAGER, every architectural vision is seen as a challenge we are ready to realize through knowledge, experience, and innovative technology. Our approach goes beyond standard designs – it begins with a dialogue between the architect and the client, working together to find solutions that are both aesthetically refined and technically feasible.

When architectural boldness meets technical precision

Our expertise allows us to deliver structurally demanding projects. This includes porticoes with three-meter spans without supporting columns, originally envisioned by Italian architect Paolo Bertozzi, where the structure ensures complete stability despite its openness. It also means mastering the installation of 3.20-meter-high elements on challenging terrain, such as the construction of the Doppler Winery, where logistics became as crucial as the build itself. Or placing a swimming pool at the heart of a home, requiring meticulous planning and coordination across disciplines.

From vision to execution

We consistently prove that bold and complex architectural concepts can be paired with technical reliability. For us, creative engineering means translating an architect’s vision and a client’s wishes into a buildable, durable, and elegant structure. This is why KAGER houses are synonymous with projects that merge architectural freedom and technical excellence – proof that aesthetics, functionality, and sustainability can coexist.

With over 30 years of experience, we build on knowledge enriched by an interdisciplinary team of experts. Architects, structural engineers, construction specialists, HVAC and electrical planners, and sustainability consultants all work together to ensure that architectural ambition is always matched with flawless technical execution.

Dynamic composition and a central pool

One of the best examples of combining architectural daring with engineering knowledge is a modern timber-glass villa, designed in collaboration with a leading architectural studio. The dynamic composition of volumes placed the project among the most demanding, requiring detailed structural planning and close coordination between architects and our production team.

The home features tall glass walls that, despite a lowered ceiling height, reach 2.70 meters, creating a remarkable sense of openness. Floor-to-ceiling glazing ensures a seamless connection to nature while maintaining structural stability through a precisely engineered timber frame.

The exterior is defined by clean lines and balanced proportions, while the interior reflects a thoughtful layout tailored to the client’s lifestyle. This dynamic form blends harmoniously with the surrounding landscape, highlighting the modern elegance and comfort typical of KAGER houses. The execution process involved architects, structural engineers, and master craftsmen working side by side to bring the client’s vision to life without compromise.

A contemporary 350 m² villa

Near Parma, a custom-designed timber villa by KAGER combines contemporary design, spaciousness, and sustainable solutions. Spread across two floors, the layout balances open living areas for family and guests with private bedrooms that ensure intimacy and comfort. The generous interior extends outdoors to a garden, swimming pool, and hot tub – a setting for complete home luxury.

Every detail was created in close collaboration with the owners, reflecting their lifestyle and aesthetics. Standout architectural elements include illuminated staircases designed to showcase a collector’s motorcycle, and geometric openings on the upper floor that flood the space with natural light. At 350 m², this villa is a prime example of how advanced technology, bespoke design, and integration with nature create a unique living experience.

A villa embedded in the alpine landscape

In the heart of the Aosta Valley, a new timber villa by KAGER was designed entirely around its owner’s needs. Contemporary lines, expansive glazing, and the warmth of wood create a home that merges effortlessly with the Alpine landscape. Inside, spacious, bright, and open interiors are carefully arranged to ensure a high-quality living environment.

The high-performance timber structure provides outstanding thermal and acoustic insulation, reducing energy consumption while offering a healthy, sustainable atmosphere. This villa represents the seamless union of modern design, innovative technology, and respect for nature – an approach that defines every KAGER house.

The most effective solution for summer cooling is a smart combination of a reversible heat pump and a mechanical ventilation system with heat recovery (MVHR), complemented by air conditioning during peak heat periods. This setup ensures a stable indoor temperature (around 22–23 °C), even during prolonged heatwaves – without abrupt temperature changes and while maintaining excellent air quality.

Benefits of active and passive cooling

Reversible heat pumps provide both heating and cooling. During summer, the cycle reverses: heat is extracted from the indoor space and transferred outside. This is particularly efficient in timber-glass houses with large glass surfaces that allow significant solar gains.

Benefits of active cooling:

• Precise temperature control
  
  
• Zonal operation (e.g., separate day and night settings)
  
  
• Compatibility with low-temperature underfloor systems
  
  

Passive cooling, on the other hand, utilizes constant ground temperature via a geothermal probe. Cool water circulates through underfloor or wall heating loops without the use of a compressor. This method is quiet and highly energy-efficient, but only up to a certain thermal load.

Passive cooling advantages:

• Extremely low energy consumption
  
  
• Minimal noise and maintenance
  
  
• Ideal for passive or energy-efficient houses
  
  

Note: The supply water temperature should remain above 18 °C to prevent condensation on pipes and surfaces, which could damage materials or create slippery floors.

Maintaining comfort with bypass function

MVHR systems prevent hot air from entering while ensuring continuous fresh air supply. Heat exchange between the outgoing and incoming air reduces the cooling system’s load.

Although ventilation alone does not cool, it greatly enhances cooling efficiency when used alongside a heat pump or ground exchanger. It provides a stable indoor climate without cold drafts or that “artificial chill.” Excess moisture is also expelled, preventing mould, furniture damage, or stale air.

Modern systems often feature a bypass function that disables heat recovery. When outdoor temperatures drop at night, cooler air enters directly, bypassing the heat exchanger. This function can be activated manually or automatically.

During hot days, set ventilation to a minimum and use night-time cooling with the bypass feature to reduce indoor heat load naturally.

Is air conditioning still necessary?

While a heat pump and MVHR cover most summer needs, internal temperatures may still rise during peak summer months (July–August). For this reason, we recommend preparing the infrastructure for future AC installation.

Maintaining 22–23 °C is optimal – especially in living and sleeping areas. If outdoor temps exceed 34 °C for several days and nights don’t cool below 20 °C, adding AC becomes necessary.

Why consider AC preparation?

• No interference with the home’s architecture
  
  
• Allows future tech flexibility
  
  
• Can be tailored to the user and location

The power of integration

A well-planned combination of a heat pump and MVHR creates one of the most efficient, complete climate control systems available today. If integrated from the design phase, the components work in harmony – without architectural compromises or retrofitting.

Key advantages:

• Heat pump: provides active or passive heating/cooling
  
  
• MVHR: ensures fresh, filtered air with minimal energy loss
  
  
• Reduced energy consumption and wear on individual components
  
  
• Even temperature distribution throughout the home
  
  
• Consistent humidity and CO₂ control for healthier air
  
  

Smartly designed systems also allow future AC installation – even if not chosen immediately. In extreme summer conditions, air conditioning may become indispensable, making this foresight valuable.

Advanced systems are fully automated. Sensors respond to indoor/outdoor conditions – like heat during the day, cool nights, or weekend absences – adjusting temperature and airflow without manual input.

The result: The heat pump maintains the base temperature, MVHR utilizes cool night air, and AC kicks in only when necessary. This ensures efficiency, comfort, and long-term sustainability.

How to ensure your system performs efficiently?

To ensure comfort during summer, proper maintenance of your heat pump and ventilation system is essential. Regular servicing, cleaning, and correct settings lower energy use and extend equipment lifespan.

Key summer maintenance tips:

• Service your heat pump before the season begins: Check key components, clean filters, inspect the cooling circuit, and calibrate settings. A well-maintained system operates quietly, uses less energy, and performs reliably.
  
  
• Switch to summer mode early: Change from heating to cooling mode and adjust all settings accordingly. Preconfigured profiles can help simplify transitions.
  
  
• Maintain passive cooling water temperature above 18 °C: This prevents condensation on pipes and surfaces, especially in underfloor or wall-based systems.
  
  

Dirty filters reduce airflow and efficiency. Clean or replace them every few months, especially before summer, when demand is high.

The creative mind behind some of KAGER’s most iconic homes is architect Irina Karlikova. With a refined sense for space, wood, and light, she has helped shape projects that fully explore the architectural potential of the Vita Nova system.

Having worked with KAGER for many years, Irina deeply understands the concept of the visible wooden skeleton and large glass surfaces—an approach that enables architectural freedom and spatial openness. She is currently designing two new timber villas—one in Slovenia, the other in Germany.

Below, we present three of her most noteworthy projects.

Lake Glass House

The Lake Glass House was thoughtfully embedded into a lush green environment. The wooden structure does not dominate the landscape but rather complements it, blending modern architecture with natural materials. Handcrafted wood plays a central role in the home’s interior.

With precise execution and aesthetic refinement, the visible timber frame becomes the defining interior feature, bringing warmth, character, and architectural elegance to the space.

In 2024, this home was awarded the prestigious prize for Best Residential Interior at the Ukrainian Building Awards.

A Glass wood house by the lake

Among Irina’s award-winning works is a glass wood house set on a lakeside property, for which she received the Best Architectural Design of a Private House award in 2021. Fully glazed façades and a carefully balanced minimalist concept convinced the jury, who praised the blend of form and function.

Inspired by traditional Bavarian log homes, the villa is surrounded by a spruce forest. Due to the sloping terrain, a basement level was incorporated into the design, allowing the building to adapt to the site without disrupting the natural surroundings.

One of the most technically challenging parts of the project was the staircase. Several versions were explored before arriving at the final design, which balances structural clarity with visual impact. The finishing elements are fully in tune with the environment: the tones of the timber beams and flooring mirror the colors of nearby bark and trees, while the interior remains calm and restrained—drawing attention to the views through the expansive glazing.

The home features two entrances: one from the basement and one from the main level. The dining area opens upward with a clerestory glass strip that floods the space with daylight and emphasizes a sense of openness.

Forest house

In this forest house, architect Irina Karlikova emphasized transparency and connection to the natural surroundings. Located in a pine forest, the house is designed with fully glazed walls that maintain continuous visual contact with the outdoors.

The interior features marble-look ceramic finishes, carefully designed lighting, and a spacious layout. With 340 m² of floor area, the ground floor includes living spaces and a home office, while the upper level houses two bedrooms with en-suite bathrooms. The glazed walls connect to a gallery area above, reinforcing the home’s airiness and fluidity.

This is architecture where natural materials and thoughtful design come together in a clear, contemporary expression of living.

.

At KAGER, we believe that modern architecture deserves modern construction methods. That’s why we rely on panel construction—an approach that brings precision, efficiency and lasting protection to every home we build.

Greater precision, material protection and fewer on-site errors

At KAGER, all structural elements are manufactured in advance, in a controlled, dry production environment. Each element is produced under identical conditions, unaffected by moisture, sun or wind. This significantly increases construction quality, shortens assembly time on site and reduces the potential for errors.

Instead of transporting materials to the site for gradual assembly, all key components—walls, ceilings, and roof elements—are pre-assembled and finished in the factory. Already during production, elements are fitted with windows or large glass surfaces, doors, installation layers, thermal insulation, joint protections and surface finishes.

When the components leave the production facility, they are fully coordinated and ready for installation. They arrive on site as final, protected building parts that require no additional adjustments and form a stable and energy-efficient structure.

More than just a technical advantage

The main advantage of KAGER’s panel construction lies in the fact that the entire structural process is shifted from the building site to a protected indoor space. Wooden components are never exposed to moisture, UV rays or snow, ensuring long-term stability, dimensional accuracy and full material protection.

This type of construction allows for standardized quality—from CNC timber processing and handcrafted detailing to certified procedures that ensure every component is tested and ready for precise assembly.

Panel construction is therefore not only faster, but also safer and more energy-efficient.

Panel construction with visible wooden skeleton

KAGER is one of the few that combines the advantages of panel construction with a visible wooden skeleton. It is a system in which the load-bearing elements—columns and beams—are placed in a precise grid and remain visible even after construction is completed.

Between these load-bearing elements, factory-installed panel infills are added. These can be solid (insulated) or transparent, in the form of large glazed surfaces. This approach allows exceptional flexibility in the design of façades and interior walls, as they are not load-bearing and do not restrict architectural planning.

Above or between the primary structure, secondary elements such as ceilings are placed, forming a stable and lasting structure together with the skeleton. Wooden beams often remain exposed and highlight the warmth, natural character, and structural clarity of the home.

The end result is bright, airy and architecturally distinct spaces—a combination of timber skeleton and glass or wooden infills that define the timeless character of every KAGER home.

How panel construction differs from skeletal on-site building

Some prefab house providers still build directly on-site, where wooden structural components are assembled at the location. This process happens outdoors, without protection from the elements.

Wood that should remain dry is often exposed to moisture from the start, affecting its dimensional stability and long-term durability. Due to unstable weather conditions (temperature, humidity) and different construction teams, the final result is less predictable.

Insulation and installations are often added later, in suboptimal conditions. There is no factory control over assembly details, so any flaws only become visible later—either as energy losses or as structural weaknesses.

On-site construction therefore requires more coordination, logistics and carries higher risks. While in panel construction every component is pre-prepared, the quality of skeletal on-site construction depends on many variables that are difficult to fully control.

Why KAGER’s panel construction is a long-term solution

KAGER’s panel construction is not a compromise between speed and quality—it is a solution that delivers both. Because every part is produced under predefined conditions, the final result is:

• a sustainable wooden structure with a high level of protection,
  
  
• an architecturally flexible design with large glass surfaces, open floor plans and bright interiors,
  
  
• a reliable system with minimal environmental impact, as construction waste and transport are significantly reduced.

Building a KAGER home is never weather-dependent. The timber stays dry, the structure remains precise, and the result is long-lasting.

Panel construction is not just about speed—it ensures standardized quality, energy efficiency and durability. This is one of the fundamental differences between our approach and those who still assemble skeleton structures directly on site.

This year has been dynamic. After a strong start, we’re now moving into a full season of new projects. Every day, we’re working on new architectural concepts — all different in form, yet unified in approach.

Diverse designs, a unified approach

When we look at the houses we’ve recently designed, one thing becomes clear: no two are alike. This variety proves that our architecture does not rely on predefined solutions, but grows from the space and the people it is created for.

From traditional gable-roofed houses with exposed timber structures to contemporary homes with hidden frames and floor-to-ceiling glass walls — the range of expressions made possible by the Vita Nova system is vast. And in this adaptability, we see the greatest strength of our architecture.</p

At the core of every project is our individual approach. No KAGER house is based on a predesigned model — each one is a response to light, location and lifestyle.

Every home begins with your story

Our process is based on an individual conceptual solution — not a template, but a design response to your specific needs, location and way of living.

We begin with a site visit. We observe how the land opens to light, where the best views are, and how the terrain defines the natural balance between openness and privacy. After a full analysis of orientation, access, terrain and sun path, we define key principles together. Then, we talk — about your routines, habits, rhythm of the day and expectations.

Only once we understand all of this do we begin to design the home — one that will truly be yours.

We offer three versions: from a basic design concept with exterior visualisations to a more detailed version with advanced renderings, and finally a comprehensive package that includes the conceptual interior design as well. Each option helps you visualise your future home — in space, materials and atmosphere.

The Vita Nova Technology

This level of individual design is made possible by our Vita Nova technology, which is based on a timber and glass skeletal structure. Here, the load is carried by wooden columns — meaning that internal walls are not structural. This allows for open floor plans, generous volumes, double-height spaces or smaller, more intimate rooms.

It also makes large glazed surfaces possible — bringing in natural light and strengthening the connection to the outdoors.

The system allows for a variety of architectural expressions: from traditional exposed timber frames that highlight the warmth and structure of the house, to clean minimalist lines where the structure is hidden. Every home can be fully adapted to its context — and to the people who will live in it.

Materials, finishes and decisions in your hands

A key part of the process is shaping the final look and feel of your home. You decide whether the structure will be exposed or hidden, which materials and colours to use, which architectural elements to highlight, and how you want your house to welcome you each day.

From façade cladding and glass types to shading systems, insulation levels and structural solutions — every detail can be adapted to match your energy goals and aesthetic preferences. Each decision influences how the house works and how it feels — but always with the support and expertise of our team.

In KAGER architecture, wood is more than just a construction element. It’s a core part of a living philosophy — one that values timelessness, sustainability and a strong connection to nature.

Wood as an architectural material — with responsibility

But natural materials are not inert. They require thoughtful protection, as they’re affected by both weather and time. With the right care and protection, wood can remain beautiful and stable for decades. Sunlight — our most important source of natural light — is also one of the main elements that impacts the durability and appearance of exposed wooden surfaces.

The impact of sunlight on wood

Natural materials inevitably respond to external conditions. UV rays break down lignin in the wood, leading to fading, loss of sheen, surface roughness and cracking. The most exposed elements are typically located on the south and southwest façades, as well as on open architectural features such as pergolas and overhangs.

This is why, in every KAGER house, wood protection begins at the design level. Shading systems, deeper eaves and well-placed overhangs reduce direct exposure and significantly prolong the lifespan of the timber structure. Yet orientation alone is not enough — protection also depends on careful material selection and preparation.

Protection starts in production

All load-bearing structures are made from glued laminated timber (BSH), known for its high strength and long-term dimensional stability. BSH consists of multiple layers of technically dried timber, bonded together under precisely controlled conditions. By removing knots and imperfections, and aligning the grain in alternating directions, we reduce internal stresses, prevent warping and minimize the risk of cracks.

Protection begins in our production facility. Every visible wooden element is hand-inspected, sanded and coated with a base finish that reduces moisture and heat absorption. Connections and joints are designed to prevent water retention or localized stress in the timber. These early steps reduce future maintenance needs and help preserve the long-term value of your home.

Wood quality and certifications

The value of wooden surfaces lies not only in their appearance, but in their certified origin, technical compliance and responsible sourcing. All timber used in our homes is PEFC™ certified, guaranteeing it comes from sustainably managed forests.

Our production complies with the European EN 14080 standard for BSH glulam timber and is CE-marked, confirming mechanical strength and construction safety. We also meet the RAL quality mark and the demanding German DIN 1052 standards. Together, these certifications ensure consistently high levels of quality, safety and material integrity.

How often is maintenance needed?

Even the best timber needs occasional care. The protective finish on wooden surfaces must be renewed periodically, depending on the type of coating, degree of exposure and local conditions.

Recommended intervals:

• Translucent coatings (lazures): Every 2 years on average — or sooner for highly exposed areas (e.g. high-altitude locations, direct sun).
  
  
• Opaque coatings (which fully cover the wood’s texture): Last around 5 years before reapplication.
  
  

What matters most is not the calendar — but the surface condition. Signs like fading color, roughness or water not beading on the surface are clear indicators that it’s time to recoat. Regular inspections help avoid costly interventions and preserve the aesthetic value of your home.

.

Architecture is facing a new responsibility — to shape living environments that are not only aesthetically refined but also sustainable. In this context, wood is stepping into the spotlight. As a renewable resource with remarkable environmental and technical properties, it offers an answer to the urgent challenges of our time.

A shared responsibility toward nature

Earth Day reminds us each year of our collective responsibility to care for the environment — including through architecture. If we want to create high-quality living spaces, we need to think long-term. That means choosing materials consciously, understanding the environmental impact of our decisions and asking ourselves what kind of world we’re leaving behind.

Reducing carbon emissions with wood

Wood is one of the few renewable materials that can actively reduce the carbon footprint. As trees grow, they absorb CO₂ from the atmosphere and store it in the wood — and this carbon remains locked in the timber even after the tree is harvested. If we leave wood in the forest, it decomposes and releases carbon. If we burn it, we release the carbon instantly. But if we use it in construction, the carbon remains stored for decades. That’s why timber construction is such a valuable contribution to climate solutions.

From slovenian heritage to modern timber construction

Slovenia is the fourth most forested country in Europe, with over 60% of its land covered by forests and home to more than 350 tree species. Nearly every fourth citizen owns a piece of forest. This strong connection to wood is deeply embedded in our identity, heritage and way of living. Forests shape our landscape and play an essential role in climate regulation, air quality and water cycles — yet they are often overlooked. Wood is one of the most effective paths toward sustainability, offering solutions that are environmentally and generationally responsible.

The traditional Slovenian hayrack is more than a cultural symbol — it’s proof that wooden structures can stand the test of time. At KAGER HIŠA, we continue this tradition through modern timber frame construction using engineered wood. These structures offer exceptional strength and stability, while glazed surfaces ensure excellent insulation. Since load-bearing functions are carried by wooden posts, interior walls are non-structural and can be easily repositioned — offering flexibility both in planning and in future adjustments.

Building with nature in mind

At KAGER HIŠA, every home is designed with the entire life cycle in mind. Our sustainable approach includes:

• Large glass surfaces, maximizing natural light and reducing the need for artificial lighting, while opening interiors to the outdoors.
  
  
• Excellent thermal insulation, resulting in low energy demand and high living comfort.
  
  
• Up to 80% less construction waste compared to traditional methods, thanks to precise manufacturing and dry construction.
  
  
• Natural insulation materials that create a healthy indoor climate.
  
  
• Spruce as the main construction material, helping regulate humidity and temperature.
  
  

Wood has accompanied humanity for centuries — but today, it has the potential for a new role. As the foundation of sustainable, modern architecture, it combines a low carbon footprint, energy efficiency and design excellence. KAGER homes are a tribute to wood and to nature. They represent our commitment to building for the future.

.

In today’s fast-paced world, where technology often takes the lead, our connection with nature has never been more important. Biophilic design goes beyond trends — it’s a holistic approach to creating spaces that promote wellbeing and restore inner calm. At KAGER, this connection to nature is at the heart of how we design homes — through architecture, materials, and every thoughtful detail.

Biophilic design as a way of living

Biophilic design is based on the idea that contact with nature has a positive impact on how we feel. That’s why we integrate natural materials, daylight, greenery, and open views into every home. It’s a thoughtful design philosophy — one that’s felt the moment you walk through the door.

Nature as part of architectural thinking

At KAGER HIŠA, the interior is not an afterthought. It’s part of the architectural concept from the very beginning. Our homes are designed to be bright, fluid, and open toward the outdoors. The timber frame construction allows for large glass surfaces, open floor plans, and a layout that connects indoor and outdoor living.

Wood is not just a visual element — it brings warmth, sustainability, and a natural atmosphere to the home. As the primary building material in KAGER homes, it plays a key role in creating a healthy indoor climate and a sense of comfort.

Sunlight is carefully considered from the start of the design process. Orientation, window placement, and open sightlines are tailored to maximize natural light and capture the most beautiful views. Daylight and outdoor connection become part of everyday life — not just visually, but emotionally.

A home that brings you closer to a nature

At KAGER HIŠA, biophilic design is more than a style — it’s a way of thinking. By combining wood, natural light, and open views, we create homes that offer more than shelter. We create spaces that feel good to live in — places where life feels simpler, slower, and more connected to the world around us.

.

When building a home, choosing the right construction method is about more than just looks or timelines. For many, long-term reliability and quality assurance are key. At KAGER, these values are built into every house — from the very first drawing to the final detail on site.

Why warranty matters in prefab construction?

Every KAGER house comes with a 30-year structural warranty and an additional 3-year warranty for potential hidden defects. This commitment reflects not only our confidence in the construction process but also our long-standing responsibility toward each homeowner.

Quality is never a coincidence

What makes true quality is not luck — it’s the result of a carefully planned and executed process. From the initial planning stages to manufacturing, delivery, and installation, every phase is handled with precision. Each component is tracked and certified, ensuring full transparency and traceability.

To ensure consistency, we rely on permanent in-house installation crews and certified external partners. This allows us to minimise errors, deliver faster response times, and ensure each home is perfectly aligned in design, execution and materials.

From the first idea to the last detail

Unlike traditional construction, where homeowners are often left on their own after completion, with KAGER you know from the start who is guiding every step of your home’s creation. And you can trust that quality and attention to detail are part of the process from day one.

Planica. The final act of the season. Packed stands, a roaring home crowd, and the perfect moment for the biggest win of his career.

With an extraordinary flight of 247.5 meters, Anže Lanišek set a new personal best and claimed his first career victory on the Planica flying hill. A moment he had long wished for – and finally made the most of, right at home.

Winning at home – and in the air

It’s been a season we’ll remember for a long time. Podium finishes, near-misses, and now – a perfect ending with a victory in Planica.

Anže once again proved that patience, persistence, and hard work always pay off. His consistency in the second half of the season and calm focus were the marks of an experienced athlete who trusted his chance would come. And it did – in the best possible moment.

“This is the sweetest win”

“Without a doubt, this is the sweetest win. I’ve waited a long time for this. I came close a few times. So happy. It’s true what they say – fourth time’s the charm,” said Anže after his win.

The final day of the season brought everything together – the work built through the winter, focus in the quieter months, and the energy saved for the moment it would all come together. That’s exactly what happened in Planica.

A season behind, a new journey ahead

An extraordinary season comes to a perfect close – and a new chapter is already beginning for Anže.

We’re proud to have signed our first sponsorship agreement with him and even more excited to now walk alongside him in the early stages of designing his new home.

When we imagine building a new home, we often focus on the needs we have right now. But what happens in ten or twenty years? Families grow, work moves into the home, children move out, and rooms gain new purposes. That’s why flexibility in architecture isn’t just a luxury – it’s a necessity.

At KAGER, we’ve been building timber frame houses for over 35 years. Our construction method allows for open and customizable spaces that can be adapted easily over time. With the combination of our Vita Nova systems and precise craftsmanship, we create homes that reflect your lifestyle today – and tomorrow.

Timber frame construction: The structure behind every KAGER home

Timber frame construction is more than just a method – it’s a mindset. At KAGER, it forms the basis of every home we build. Instead of relying on load-bearing walls, the structure is supported by a visible timber frame. This allows you to freely adjust the interior layout without major structural changes.

Because the walls aren’t load-bearing, they can be moved, added or removed at any stage – whether during planning or years later. This design also allows for large glass surfaces and seamless transitions between indoor and outdoor spaces. In other words, the structure brings together aesthetics, flexibility and energy efficiency in one solution.

Vita Nova systems: different styles, same flexibility

All KAGER homes are built on the same structural foundation, but the final appearance depends on the façade system you choose. Vita Nova offers three design systems – all based on the same timber frame, but with unique architectural expressions.

Vita Nova with integrated blinds: Ideal for those who appreciate the warmth of wood and classic details. The structure remains visible, and blinds are hidden behind wooden covers to preserve a clean, timeless façade.

Vita Nova with aluminium cladding: Designed for lovers of modern, minimalist architecture. The aluminium elements offer added durability and a sleek finish, while integrated blinds enhance energy efficiency.

Vita Nova with wooden cladding: The perfect choice for those who value natural aesthetics. The frame is covered with wood, creating a warm, earthy impression. External blinds can be chosen freely depending on your preferences.

Each system is factory-assembled to ensure high precision and fast on-site installation. Inside, the frame is painted in your selected colour from the KAGER palette, adding a personal touch to every detail.

One structure, endless possibilities

With the Vita Nova system, almost every element of your home can be customized:

Visible or hidden frame: Show off the structure or mask it with wood or aluminium.

Façade materials: Combine glass walls, wood panels, or both.

Colours: Select your desired finish for the timber structure, windows, and doors.

Interior layout: Design open-plan spaces or create enclosed rooms as your life evolves.

Construction system and insulation: Choose between various construction types and insulation materials to achieve your energy goals.

Why adapt your lifestyle to your home – when your home can adapt to you? With KAGER’s timber frame construction and Vita Nova systems, your home becomes a living space that grows with you. Whether you’re planning for today or thinking ahead to future changes, this is architecture that supports you through every life stage.

A truly solid home doesn’t depend on the time of year. Instead, it depends on how it’s made and what it’s made of. Our houses are constructed from laminated spruce (BSH), a material known for its strength and dimensional stability. That means whether it’s summer or winter, your home will be just as structurally sound. So when is winter actually the better option?

Believe it or not, winter often brings conditions that make construction more efficient – especially when working with wood. The air is drier, the site cleaner, and assembly faster. A house built in winter can be move-in ready by spring.

4 advantages of building in winter

A cleaner, less muddy site: Dry and frozen ground means less mud, which is especially important when working with exposed wooden elements. The cleaner the site, the better the final finish.

Lower humidity, no heavy rainfall: Less rain and lower humidity levels mean the wood stays dry. That helps prevent future warping or cracking – essential for long-term durability.

Better structural stability: Wooden elements settle more evenly and consistently in lower temperatures. This reduces movement later and increases the long-term structural performance of the house.

Move in by summer: Build in winter, and your home is ready for interior work and landscaping as soon as the warmer months arrive. No waiting around – just smooth progress.

Why we build all year at KAGER

High-performance materials: We use laminated spruce BSH in every load-bearing structure. This wood doesn’t warp, crack, or absorb moisture easily, which guarantees strength and stability regardless of outside conditions.

Precision manufacturing in a controlled environment: All elements are pre-fabricated in our production facility. This allows us to machine, treat and protect every piece of wood in perfect conditions – away from wind, rain or temperature swings.

Fast on-site assembly: Thanks to pre-made components, building on-site usually takes just a few days. This reduces weather-related risks and allows precise scheduling year-round.

Dry construction process: Unlike traditional methods that involve wet processes like concrete, our wooden homes are built dry – which means there’s almost no impact from cold or damp weather. Quality stays high and timelines stay on track.

With the right system, winter isn’t a limitation – it’s an opportunity. Thanks to our technology, expert team and fine-tuned process, we’re able to build homes of the highest quality throughout the year. So if you’re thinking of building a home, don’t wait for the “right” season. With KAGER, any time is the right time.

Choosing to build a home is one of life’s most important decisions. That’s why it matters that future homeowners not only trust our work but also get to see the process up close. At KAGER, we welcome anyone interested in understanding the quality and precision behind each element and every stage of the production.

This is exactly what ski jumper Anže Lanišek wanted to experience – to see how wooden-glass homes are built from the inside out. Together with Nastja, he visited our production facility in Ptuj, where he got a firsthand look at the work, people, and dedication that go into every KAGER home.

.              

Boutique production for a unique final result

At KAGER, we don’t build standardized homes. Each house is custom-designed to suit a specific plot and the lifestyle of its owners. This means the production process isn’t serial – it’s individual. Every home is created with care and precision, from the first sketch to the final detail.

What impressed Anže the most was this uniqueness. He followed the process step by step – from preparing wall panels and wooden structural elements to hand-finishing wood surfaces and fitting large glass panels.

How wall elements are made

Our skeletal structure ensures not only excellent structural stability but also complete architectural freedom. Since the load-bearing function is carried by columns and beams, exterior walls can be fully adapted – allowing for expansive glazing and seamless transitions between indoor and outdoor spaces.

Glass walls that open the home to nature

We believe that you shouldn’t have to choose between a home that feels open and one that’s energy efficient. Thanks to our Vita Nova technology, we offer both – large glass surfaces that connect your living space with nature, while maintaining excellent insulation and indoor comfort all year round.

When Anže saw how the glass walls were installed, he immediately understood what makes KAGER homes so special: “Seeing the precision behind each element really helped me understand why wooden-glass houses are different.”

Hand-finished wood for a warm and lasting impression

Another special touch in every KAGER home is the hand-finished wooden structure. This isn’t industrial production. Our craftsmen treat each component individually, ensuring that every detail is perfect. It’s this attention to detail that gives KAGER homes their distinctive warmth and timeless look.

Anže and Nastja saw how hand finishing enhances the natural beauty of the wood and how precision in installation ensures not just aesthetics but long-term durability.

Every detail reflects the people behind the work

This visit offered Anže more than just insight into how homes are built – it introduced him to the people behind them. With their skills and commitment, our team ensures that every KAGER home isn’t just well built, but also visually striking.

“Now I can truly picture what my future home will look like,” Anže said at the end of the tour – confident that his choice of a Vita Nova Classic home was the right one.

Anže Lanišek and his partner, Nastja, have chosen a house from the Vita Nova Classic architectural line for their new home. This style combines traditional elements with a modern approach, resulting in a timeless aesthetic and functionality. Below, we reveal their vision for their home, detailing its exterior design and interior layout.

.              

Wooden structure for a bright, warm, and energy-efficient home

The house will feature a skeletal structure made from laminated spruce wood (BSH), ensuring exceptional stability, durability, and aesthetic excellence. Glass walls with outstanding thermal insulation (0.5 W/m²K) allow abundant natural light and a visual connection to the surroundings while maintaining energy efficiency.

With its open floor plan, spacious interiors, and carefully designed details, the house offers a perfect balance between functionality and aesthetics. Large glass surfaces connect the interior with the outdoor living space—a spacious terrace and greenery—creating a sense of freedom and harmony with nature.

Well-thought-out floor plan for maximum comfort

The house is designed to provide functional and comfortable living across two floors. An open floor plan, large glass surfaces, and thoughtful room placement create a pleasant and bright living environment. The total net area is approximately 150 m², with high ceilings (2.9 m) further enhancing the sense of spaciousness.

Open and bright living area

The ground floor spans 75 m² and includes a central living area where the living room, dining room, and kitchen merge into a unified, open space. Glass walls provide ample natural lighting and visually connect the interior with the terrace and garden, fostering a continuous connection with nature. The kitchen features a functional island, ideal for meal preparation and socializing.

The ground floor also includes an additional room suitable for a home office, relaxation, or guests. A technical room housing a heat pump and ventilation system, along with a utility room, are strategically placed to minimize intrusion into the open living space. A spacious entrance area also features a sanitary space.

Upper floor—a space for privacy, comfort, and relaxation

Upstairs, the main bedroom offers privacy and comfort, complete with a spacious wardrobe. Two additional children’s rooms are bright and adaptable to various age groups, ensuring long-term usability.

A large bathroom equipped with a double sink, bathtub, and shower occupies the central part of the upper floor. Additionally, there’s a lounge area suitable for relaxation, reading, or work.

The design of the upper floor maximizes space utilization while providing the comfort and functionality essential for pleasant living.

Architectural features of Vita Nova Classic

Vita Nova Classic draws from architectural tradition, enhancing it with modern design solutions. Its foundation is classic Slovenian architecture, complemented by contemporary aesthetic elements that ensure timeless appeal and sustainable living quality.

A distinctive feature of this line is the visible wooden structure, a recognizable element both inside and outside the house. The massive wood imparts warmth and a sense of homeliness to the space while maintaining structural stability and energy efficiency.

The design of the eaves with visible rafters plays a significant role in shaping the exterior appearance, emphasizing the traditional roof form and adding the character of classic alpine houses. A suspended semicircular gutter enhances this look, contributing to the harmonious overall image of the building.

Wood serves as a key element not only in the structure but also in the details. Handcrafted wood acts as natural decor in the interior, creating a pleasant and authentic ambiance. Every detail is thoughtfully designed—even the integrated guides for blinds are discreetly hidden under wooden covers, allowing for aesthetically pleasing shading without visible additions on the facade.

For perfect precision and flawless execution, the house’s facade is completed during production, ensuring high quality and long-lasting material durability. This approach allows for precise detailing while reducing on-site assembly time.

From concept to reality

The construction of Doppler Winery presented several technical challenges that required innovative solutions and exceptional adaptability. The unique architectural design and demanding location made many phases of the project particularly complex.

Wood or concrete?

During the initial discussions with the investor, a crucial question arose:

“Can the building be constructed with a wooden structure instead of concrete?”

This inquiry led to a complete redesign of the architectural and spatial layout, requiring new engineering solutions. Additionally, the winding mountain road leading to the site posed challenges for transporting large construction elements.

Glass as a structural element

The large glass walls in the building serve both an aesthetic and structural purpose. They provide unobstructed views of the rolling hills, connecting the interior with nature while also playing a crucial structural role.

Instead of traditional concrete columns, the glass walls are designed to absorb horizontal forces such as wind and seismic loads. By directly bonding the glass surfaces to the wooden structure, the need for additional reinforcement elements was eliminated.

Height, span, and logistics – overcoming challenges

One of the most significant challenges was the height of the glass walls and the span of the open spaces. Additionally, transporting and installing these massive glass elements on such a demanding terrain required meticulous planning and precision engineering.

A perfect balance of design and engineering

Through careful coordination, advanced construction techniques, and a dedication to quality, we successfully overcame these technical challenges. The result is a building that seamlessly combines architectural elegance with structural innovation, creating a unique and sophisticated space.

Over 35 Years of Experience

Our technical solutions are based on decades of experience in building timber structures and the latest findings in the use of eco-friendly materials. The origins of our company date back to 1989, with our initial experiences in prefabricated timber houses starting in the 1970s in the USA and Germany.

Customization

Every house is individually designed according to the client’s requirements, needs, and wishes. We have satisfied more than 1000 families in Slovenia, Austria, Germany, Switzerland, Italy, France, Russia, and Ukraine with our personalized approach.

Construction Speed

Prefabricated components of KAGER houses are assembled on-site within three days. Since the construction process, except for the screeds, is dry, the house does not require prolonged drying and is ready for occupancy within eight months.

Perfection

KAGER houses meet the highest architectural standards in terms of both interior and exterior design and timeless elegance. All structural elements are produced using CNC machines based on 3D computer models, ensuring error-free construction. Our team includes civil engineers, skilled carpenters, joiners, and other professionals. All wood is handcrafted.

Optimal Execution at All Project Levels

At KAGER Hiša, we ensure optimal execution of all project phases – from initial consultation, planning, production, supervision, to final implementation.

Security

Stress-free planning with predefined deadlines, fixed construction costs, and guaranteed quality of the final product. The price for each house is determined after a thorough analysis of all client-specific requirements and expectations.

Flexibility

A KAGER house represents infinite design possibilities. We can meet any specific requirement, whether it’s a luxurious villa, a country house, or the most modern architecture. Your desires, needs, and lifestyle dictate the final appearance and function.

Energy Efficiency

The principle of every KAGER house is to use all energy sources as economically and ecologically as possible – including passive solar energy. Extensive timber-glass structures with high transparency are oriented from east to west, capturing maximum solar energy. Conversely, smaller, more cold-resistant windows face north. This design allows the house to capture and retain heat efficiently, resulting in very low heating costs.

Health and Comfort

Timber is a natural material that positively impacts health and overall well-being, creating a warm and homely atmosphere. Our houses are built from natural, renewable materials, with a construction volume smaller than traditional buildings. Additionally, the energy required for the creation and deconstruction of the house is minimal.

Earthquake Safety

KAGER houses are earthquake-safe. The supporting structure of our prefabricated timber houses has a high energy absorption capacity, making them resilient to seismic activity. This characteristic is due to the unique design, primary timber structure, cladding, and connecting materials.

By choosing KAGER House, you invest in a prefabricated timber house that offers customization, quick construction, and superior quality, all while ensuring energy efficiency and sustainability.

When deciding to build a house that guarantees good energy performance, there are many aspects to consider. At Kager, we have made this one of our strong points, achieving excellent performance in the homes of the Vita Nova line.

We carefully select projects that can exploit the bio-climatic characteristics of their location. As specialists in active and passive insulation systems, we only use premium materials and apply various types of electrical systems using renewable sources.

Our materials, our technology

The combination of high-quality materials and technologies developed over the years allows us to build houses with exceptional energy performance. For wooden walls, we use high-density wood fiber, ensuring the best thermal and acoustic insulation. Kager construction technology achieves incredibly low thermal coefficients, ranging between 0.10 W/m²K and 0.14 W/m²K.

For glass, we use triple glazing with the lowest achievable thermal coefficient value today: 0.5 W/m²K. This ensures a constant temperature inside the home during both winter and summer.

Energy consumption: data at hand

Empirical data shows that temperature variations inside Kager homes are minimal in both summer and winter. In intense cold conditions, with the heating systems off, the temperature inside the house drops by only 1°C in 24 hours. During a very hot day, turning off the cooling system results in a variation of just 1°C over 24 hours.

A Vita Nova house measuring between 180 and 220 m² consumes between 15 and 18 KW/m²/year for heating, cooling, controlled mechanical ventilation, and domestic hot water.

Our monitoring system

Measuring the performance of a house involves understanding how individual elements react to climatic conditions and energy needs as a whole. The exceptional nature of our creations lies in the balance of the entire project and the integration of each part into a single organism. This is why our homes fall into the A4 energy class or are categorized as “passive houses.”

With over 30 years of experience, we have created a monitoring network that keeps us updated on changes in living comfort and energy performance. Homes with structural glass walls have been among those that have most distinguished us in Europe.

By integrating premium materials, advanced technology and rigorous monitoring, we ensure that our Vita Nova homes provide unparalleled energy efficiency and comfort.

Design and build a Vita Nova wooden house

Achieving high energy performance in a house, especially in a wood and glass construction using Vita Nova technology, does not depend solely on the characteristics of walls, ceilings, and windows but involves various factors.

First of all, the choice of materials used allows for higher or lower performance. In our case, we only use premium materials such as high-density wood fiber and high-performance structural glass for Vita Nova walls. Secondly, the application of construction technologies aimed at saving consumption counts, such as those we have refined over 30 years of research.

This brings us to the third point: intelligent design. Suppose the first two are fundamental for obtaining an excellent project. In that case, excellence cannot be achieved without a project that can make the most of the bio-climatic characteristics of the place where the house will be built.

Data such as the thermal coefficient of structural glass walls must be inserted into the context in which the Vita Nova wall is located, making a total balance in which the response of the house as a whole is analyzed.

Intelligent design in practice

In practice, this translates into a series of architectural and energy solutions that influence the performance of the individual elements. An intelligent design must, therefore, take into account factors such as the optimal exposure of the rooms and the zenith rotation. Consequently, the provision of eaves, pergolas, porches, and terraces can protect the windows from direct sun in summer and favor radiation in winter when the sun’s trajectory is lower.

For example, the design of a house in a particularly sunny place with Vita Nova walls facing south should include the presence of overhangs that prevent the house from overheating. At the same time, in the winter months, the same overhangs would not represent a problem for cooling the house, as the sun is lower.

The technical verification of the projects

A house reacts like an organism to climatic conditions and energy needs: each element contributes to the functioning of the whole. It is up to the designer to optimize the composition of the walls, roof, reinforced concrete foundation plate, and external windows.

As builders, we take care to create only the projects proposed to us that meet these characteristics. Otherwise, we try, where possible, to make improvements in agreement with the designer. In the case of projects involving Vita Nova technology, Friedrich Kager himself takes care of the review.

Thermal variations in a Vita Nova wooden villa

Among the characteristics that make Kager wooden houses outstanding in the construction field are the remarkable energy performances we guarantee for each project. This is especially true for homes with Vita Nova windows that cover extensive surfaces and replace entire walls.

Our customers often wonder how much large windows impact energy performance. This concern is understandable: glass indeed disperses heat faster than masonry or wooden walls, potentially leading to cold interiors in winter and overheating in summer.

However, evaluating a house’s energy performance requires considering it as a whole. Homes, much like organisms, function as integrated systems. Thus, it’s essential to make an overall assessment rather than focusing on a single element. Many techniques are applied to make our homes energy efficient. In this analysis, we delve into the importance of triple glazing and active blinds in Vita Nova houses.

Kager technology

To ensure minimal temperature variations inside Kager homes, we have adopted two complementary technologies: triple glazing to prevent cooling in winter and blinds to prevent overheating in summer.

Triple glazing

The glass we use is triple-glazed, which significantly reduces the thermal insulation coefficient. On average, single-glazed windows have a coefficient approaching 5.8 W/m²K, and double-glazed windows have around 2.8 W/m²K. The glass adopted by Kager has the lowest thermal coefficient value achievable today: 0.5 W/m²K.

Blinds and sunblinds

Darkening systems are an often underestimated solution with great potential. These elements are placed in front of windows and glass to protect the home from the sun’s rays. The significant advantage of these systems is their ability to tilt the slats to regulate the amount of light and heat passing through the glass.

At Kager, we place the blinds outside the home. If inserted inside the glass, heat would still pass through the windows and enter the house. By placing them outside, they effectively shield the structure from the heat.

Additionally, an innovative technology unique to us allows for the integration of sunshade guides within the Vita Nova structure, making them invisible when closed and ensuring no aesthetic impact on the facade.

To ensure maximum living comfort, the blinds can be managed by the home automation system. This system, through light sensors, can regulate the amount of sunshine (and thus energy contribution) based on the season and the day/night cycle.

By combining high-performance materials and advanced technologies, we create homes that maintain optimal living conditions year-round. The synergy between triple glazing and external blinds is a key element in achieving the energy efficiency that Kager houses are known for.

The history of Kager construction technology is rooted in key concepts of green building, such as the environmental sustainability of the entire project lifecycle, the achievement of maximum living well-being, the optimization of energy resources, and, above all, the use of natural and high-performing materials.

The construction of a wooden house allows for significant advantages in terms of living well-being, seismic resistance, and excellent energy performance, but only if the construction technology is based on a careful selection of the wood used. All wooden houses made by Kager, consistent with the company’s commitment to excellence in quality, have a structure composed exclusively of certified quality laminated wood.

The characteristics of laminated wood

Laminated wood, unlike solid wood, has no dimensional or shape limitations linked to the size of the tree, allowing greater freedom in the design phase. The production technology of laminated wood also improves the degree of drying, guaranteeing lower humidity content, and reduces the presence of cracks or shrinkage deformations, ensuring considerable shape stability. This allows us to avoid the need for pillars and metal carpentry in load-bearing structures, even for much larger dimensions than solid wood.

The product standard for laminated wood certification is the same as for solid wood, EN 14081. Both products are certified with the same level of reliability and safety.

Craftsmanship

The Kager quality standard requires that each processing step is carried out with the attention to detail that makes our prefabricated wooden houses special.

The knots naturally present in wood are one of the most beautiful and appreciated aesthetic characteristics of this material, but they represent a potential point of fragility on a structural level, as cracks can develop from the knots. For this reason, Kager craftsmen manually remove every knot present, replacing them with specific reinforcement dowels.

Once this phase is completed, the wall assembly process begins, carried out by hand by specialized technicians with decades of experience. From the assembly of the load-bearing sections to the blowing in of the insulating material and the installation of the wood fiber and natural fiber panels, each phase within the Kager factory ensures maximum control of the quality level of each module that leaves the production line and the absence of thermal bridges in the walls.

By combining these meticulous processes with high-quality materials, Kager ensures that every prefabricated wooden house not only meets but exceeds standards for durability, energy efficiency, and aesthetic appeal.

Prefabrication is a construction method that offers various benefits, some of which are universally recognized while others are less known but equally important. Kager’s production technology is based on wooden prefabrication, requiring that all the structural walls are built (or prefabricated) inside the Kager factory in Slovenia.

This is where Kager’s experience, construction technology, and artisan technique come together to create our wooden walls. Subsequently, the walls are transported to the construction site, where our specialized technicians assemble them to create a new home.

But where is this particular production process most useful?

Energy efficiency

Prefabrication brings significant advantages in terms of energy efficiency because it allows us to eliminate many problems related to critical points for thermal insulation, such as windows and doors. Kager construction technology requires that all parts of the walls are completed during the production process in the factory, from the structural components to the materials for thermal and acoustic insulation, up to the fixtures and fittings.

The installation of these elements takes place in a controlled and comfortable environment, where our technicians can operate with the utmost attention to detail and in greater safety than on the construction site, where there are inevitably more risks and operational impediments. This ensures that it is possible to reach the highest quality standards and achieve the total absence of thermal bridges.

Thermal bridges, often found around window and door frames, are areas of the building envelope where greater heat exchange occurs between inside and outside, leading to losses that increase energy consumption. Furthermore, producing the walls within the factory allows us to drastically reduce the risk of damaging the most delicate components, operating in a protected environment with maximum order and cleanliness.

Reduced construction times

Through experience and constant updates, Kager has developed and perfected a unique construction method that combines design, production, construction, and assembly. This results in perfect synergy between the elements, precise to the centimeter, capable of achieving excellent results in thermal and wind tightness, as well as seismic stability.

One significant advantage of this process is the reduction in construction times. Thanks to prefabrication, the work carried out on-site is significantly reduced, shortening on-site construction times to a minimum and delivering the new house to our customers sooner.

Construction times typically last just 2-3 weeks for the advanced raw material stage, while the entire process from the ground floor slab to delivery to the customer is completed in just 4-5 months. (watch the video of the assembly on site ).

Anyone who lives in a Kager wooden house quickly forgets about the high costs associated with winter heating that affect most traditional masonry buildings. But what are the reasons behind this difference? Here are the three main characteristics of Kager homes that allow you to maintain low heating costs even when external temperatures drop.

1. Absence of structural thermal bridges

Thermal bridges are areas of a building envelope where unwanted heat flow is generated between the inside and outside. These are most common at joints (between walls and floors, walls and ceilings, or roof beams and walls), where the geometric characteristics and the meeting of different materials can reduce the insulating capacity of the structure.

To address this issue, Kager engineers have developed various innovative solutions over the years, including the use of the highest quality materials which are unique in the wooden construction industry. Some design solutions include a double roof that guarantees proper insulation without thermal issues and the creation of fixing and anchoring systems for the structures (walls-walls, walls-floor, walls-basement reinforced concrete) combined with corner sealing systems. These elements remain a crucial aspect of Kager’s technological heritage.

2. Perfect insulation in window connections

Windows and French doors are the most critical thermal bridges in a home during winter. While design and living comfort recommend increasing glass surfaces to improve internal lighting conditions (and thus reduce energy consumption for lighting in winter), the connection points between windows and walls can often create drafts and lower internal temperatures.

It is not enough to have highly insulated glass (double or triple glazing); the installation phase is very delicate and can undermine the insulation capabilities of the frame. Prefabrication offers significant advantages in this case. In Kager prefabricated wooden houses, all fixtures are assembled in the factory in a protected and controlled environment where it is possible to achieve total insulation, free of imperfections, rich in details and technical measures that ensure the complete absence of thermal bridges.

3. Intelligent solutions for air exchange

Air exchange improves the quality of the air we breathe in our homes daily, especially when traditional heating systems excessively lower the humidity percentage, causing typical seasonal ailments.

Kager wooden houses are equipped with advanced controlled mechanical ventilation systems (VMC), which allow the air in the house to be renewed up to 8 times a day with the possibility of pre-heating the incoming air using the heat of the outgoing air. This way, it is no longer necessary to open the windows to breathe clean air, filtered against dust and pollen and treated to achieve ideal humidity conditions.

Would you like to know more?

In this article, we have explored some solutions that help reduce heating costs in a Kager house. To find out all the details, contact us and request an appointment with one of our consultants.

1. Construction times

Kager construction technology leverages the benefits of prefabrication to ensure extremely short construction times: from the ground floor slab to delivery to the customer in just 4-5 months. In contrast, a traditional house requires over 18 months of work, often compounded by difficulties in providing the client with definitive deadlines.

2. Certain costs

Kager wooden houses come with a procurement contract that includes a cost guarantee, ensuring that you won’t encounter any unpleasant surprises along the way. Traditional constructions often have quotes that can fluctuate during construction due to variations and unforeseen events.

3. Simplicity of procedures

With Kager, there is a single point of contact: our team coordinates all the figures involved in the process, maximizing simplification. In traditional constructions, it is common for the customer to interact with multiple specialists in individual areas of activity.

4. Customization

The flexibility of Kager construction technology, which is completely tailor-made, allows for no constraints during the design phase. Thanks to the lightness of wood, it is also possible to build elevations or extensions of existing structures. Traditional houses often face constraints during construction, and in many cases, interventions to raise or expand existing structures are not possible due to the high weight of the structure.

5. Living comfort

A Kager wooden house guarantees high well-being. The temperature inside the house does not fluctuate significantly with changes in the outside temperature (variation less than 1°C during a winter night). In summer, it remains cool even without air conditioning, thanks to high thermal insulation and low humidity.

Thus, there is no risk of mold in indoor environments. Traditional houses often have high humidity, thermal bridges, mold, and internal temperature fluctuations that necessitate air conditioning, especially in attics.

6. Security

A Kager home is fire-resistant. The external materials and internal sections of the walls allow a slow advance of the combustion front, ensuring the structure’s resistance for many hours even in the event of serious fires.

Traditional construction homes often use metal elements to ensure structural integrity. However, these materials are negatively affected by the high temperatures that can develop during a fire, risking structural failure.

7. Consumption

A 100 m² Kager house in energy class A4 has an extremely low annual heating cost, averaging €318 with methane gas, €217 with pellets, and €285 with a heat pump. Heating a traditional house in energy class C (70% of houses in Europe) of 100 m² costs on average up to four times as much: €1,090 with methane gas, €870 with pellets, and €1,200 with a heat pump.

8. Maintenance

Extraordinary maintenance of Kager wooden houses is simplified by the structure of the walls, optimized to facilitate interventions on the electrical and plumbing systems. Ordinary maintenance is comparable to that of traditional houses. The extraordinary maintenance of concrete and brick houses is demanding; even simple interventions often require long times and high costs.

9. Warranty

The great durability of Kager wooden houses is confirmed by a 30-year guarantee on all structural parts. This is possible thanks to the correct management of humidity and the presence of thermal breaks. Traditional houses generally only offer the ten-year guarantee for serious defects as provided for by the Civil Code.

10. Investment

The market value of a Kager wooden house today is more than 10% higher than that of a similar traditional house, thanks to its durability and high energy efficiency. Traditional houses that are not energy efficient depreciate over time. Furthermore, the thickness of the thermal insulation in traditional walls removes up to 7% of the internal walkable surface compared to a Kager house.

THE DIFFERENCES BETWEEN A KAGER HOUSE AND OTHER WOODEN HOUSES

What makes a Kager house special compared to other wooden houses? To answer this question, we compared the main aspects that affect the quality of a wooden house and living well-being.

1. Custom-made homes

Each Kager wooden house is completely custom-made. We develop each project with absolute care, from foundations to finishes, to create your new home exactly as you have always dreamed of, without compromises.

Most companies in the wooden house sector create catalog houses with standard stylistic and functional solutions. Some manufacturers offer custom-built homes starting from predefined modules, with limited customization possibilities.

2. No restrictions on furnishings

Kager construction technology requires that each wall of the house has a structure capable of supporting suspended wall furniture. This allows for furniture design without constraints, with hanging solutions on both internal and perimeter walls, and the ability to change their layout as desired.

In many wooden houses, the furniture layout cannot be customized by the buyer because not all walls have sufficient capacity to support hanging furniture. For example, the kitchen must follow a predefined layout, preventing future changes to the furnishings.

3. Accessibility of the facilities

Thanks to the system compartment solution introduced by Kager and present in all our homes, it is possible to easily access an internal area of the walls dedicated to electrical and plumbing systems. This ensures that all subsequent maintenance or modifications to the systems do not cause concern.

In most wooden houses, the electrical and plumbing systems are arranged in specific positions depending on the house model, leading to technical difficulties and risks to the wall structure during subsequent maintenance or modification. Some manufacturers offer the system compartment solution as a paid option.

THE DETAILS THAT REVEAL EXCELLENCE

4. Natural materials

Kager uses completely natural materials for the thermal insulation of the walls. Wood fiber is a natural, breathable material, free from glues or added chemicals, offering the best thermal insulation performance.

Most wooden houses built throughout Europe use insulating materials derived from petroleum. These materials offer a compromise between cost and thermal performance but have a strong environmental impact and prevent proper wood transpiration. Some builders offer walls made from natural materials as a paid option.

5. Fire resistance

Fire resistance in Kager wooden houses is ensured by the adoption of a special technical sheet inserted in all internal and perimeter walls, which slows the advancement of the combustion front while protecting structural parts. The fire resistance of Kager structures is certified by Holz Forschung Austria, an independent European certification body.

Many companies, to keep costs low, produce wooden houses without this safety feature for all walls, resulting in partial resistance that does not guarantee structural integrity in case of a fire.

6. Breathability of wood

Using wood fiber as a thermal insulator means vapor barriers are not used in Kager house walls. Vapor barriers are synthetic materials with high thermal insulating power that prevent necessary wood transpiration. Wood, being a living material, requires adequate ventilation to resist environmental humidity over time.

Vapor barriers are standard in the wooden house sector because they guarantee high thermal insulation with limited dimensions and costs. However, they create ideal conditions for condensation and mold formation, risking the wooden structure’s durability.

7. High quality laminated wood

Kager construction technology uses only laminated wood for house structures. This material offers significant benefits in terms of resistance and stability over time, allowing greater design freedom without needing support pillars and metal carpentry in load-bearing structures.

A high percentage of wooden houses use solid wood for structural parts. Although this product is certified with the same reliability and safety level as laminated wood, it implies various design constraints due to its tendency to develop cracks and deformations.

8. No-gas houses only

All Kager wooden houses are built without a gas connection, reflecting Kager’s innovative character in both system technology and the casing. Most of the energy used comes from renewable sources.

Most manufacturers offer gas connections as a standard solution. When this complicates the customer (e.g., land not reached by a methane pipeline), the no-gas option is subject to a fee.

9. 35-year guarantee

Due to the high construction quality, Kager offers a thirty-year guarantee on all structural parts of its wooden houses. Almost all companies in Europe offer only the minimum ten-year guarantee required by law.

10. CE certification on the entire production process

Kager boasts CE certification for the entire production process, the most authoritative certification currently obtainable in Europe. Wooden house manufacturers typically obtain CE certification only on individual materials, not the entire production process.

11. Transparency policy

Kager commits to developing and proposing transparent, complete, and detailed estimates to offer certain costs and maximum transparency. We only indicate the products that have been selected for the project and that meet the customer and technical designer’s requirements.

One of the most common problems for those entering the wooden house world is the difficulty in understanding estimates from different companies. The complexity of the regulatory landscape and the tendency to provide partial indications on the technologies used often lead to difficult interpretation, risking significant variations during construction with a clear impact on final costs.

12. History

Kager is a company specialized in wooden houses, active in Europe for over 30 years. Choosing a builder who has contributed to the wooden house sector’s success guarantees safety and reliability throughout the process, from the contract to after-sales assistance.

The wooden house sector is growing in Europe, with more customers choosing to invest in green building, leading several companies to enter this market. Many companies, without a strong product culture, purchase and resell catalog products guided solely by price.

The importance of seismic safety

To ensure safety, especially in today’s world, a house must guarantee high seismic resistance. Kager wooden houses, developed with decades of research, leverage the resistance and elasticity of wood to provide seismic resistance unparalleled in traditional masonry constructions.

A concrete example

The Kager wooden house shown in this image was built in the municipality of Argenta, in the province of Ferrara, just 42 km away from the epicenter of the 2012 Emilia earthquake.

THE 2012 EARTHQUAKE

EFFECTS ON THE BUILDING

How a Kager wooden house reacts to an earthquake

In the event of an earthquake, a Kager wooden house can excellently absorb the seismic waves, even of high magnitude. The characteristics of Kager construction technology allow for optimal controlled deformation, and the elasticity of the wood enables the structure to return to normal without consequences once the stresses have ceased. A fundamental role is played by the lightness of the structure, which results in smaller forces compared to a brick house.

«The surrounding houses were full of cracks, chimneys had collapsed, a disaster.
My Kager house, on the other hand, had not suffered any damage.”

 Max Salani
Owner of the Kager house in Argenta

The owner’s story

The earthquake had its epicenter in the municipality of Finale Emilia, just 42 km from Argenta, where a Kager house is located. Despite the extensive damage to buildings in the area, the Kager house remained unscathed. The homeowner, who was inside his home with his family at the time of the earthquake, recounts his experience: “The house was swinging, shaking, but I thought: ‘It’s an earthquake-proof house, it will resist.’”
