Can a 50 m² house look like a small contemporary building? That's the effect the KAYA 4L aims to achieve. This prefabricated wooden model stands out for its vertical layout, urban aesthetic and floor plan that includes two bathrooms, a 20 m² open-plan kitchen and living area, and a porch that can be enjoyed from day one. Priced at €49,077, it presents itself as a compact option that doesn't compromise on light, privacy or versatility.

The real appeal becomes apparent once you step inside. The ground floor serves as the heart of daily life, centred around an open-plan kitchen and living room, while the upper floor is dedicated to relaxation, with a main bedroom and a multipurpose room that can adapt to different needs. There's also an unusual feature for a prefabricated home of this size: two full bathrooms, one on each floor, both with space for a shower.

A wooden "mini building" with an urban aesthetic

The KAYA 4L moves away from the stereotypical country cabin, opting instead for a compact, block-like form with clean lines and vertical cladding. The combination of wood and dark finishes enhances its contemporary urban character, making it instantly recognisable. This is more than a stylistic choice: the vertical design continues indoors, where height is used to separate functions and create privacy without increasing the building footprint. The result is a home that, despite its size, feels organised, bright and architecturally striking.

The large glazed areas do more than redefine the façade; they also transform the living experience. Their purpose is to maximise natural light, open up views and enhance the sense of space within a compact footprint. Visually, the wood adds warmth to the design, while the dark-framed glazing gives the home the appearance of a carefully designed architectural project, closer to a contemporary building than a traditional cabin.

50 m2 spread over two floors

The home's 50 square metres are distributed across two levels, creating spaces suited to different moments of the day. On the ground floor is the daytime area: a 20 m² open-plan space combining the kitchen and living room for cooking, socialising and everyday family life. Upstairs is the sleeping area: the main bedroom and a multipurpose room that can be used as a home office or converted into a second bedroom as needed. This vertical separation helps preserve privacy and reduce interference between activities.

The layout also promotes a strong sense of order. The ground floor accommodates movement, conversation and daily activity, while the upper floor is designed for rest or focused work. In a compact home, this approach can make a significant difference compared with single-storey layouts, where different functions often overlap. Here, the staircase acts as an effective divider that helps organise everyday life.

Two bathrooms in a compact prefab house: less waiting, greater comfort

One of the model's most notable features is the inclusion of two full bathrooms, one on each floor, both with shower space. This design choice eliminates the need to move between floors at night and frees up the downstairs bathroom when guests are visiting or household routines overlap. In homes of this size, two bathrooms are typically a rarity. Here, they become a practical advantage that enhances comfort without increasing the overall floor area.

Beyond the number of bathrooms, their positioning is equally important. Having a bathroom next to the bedroom improves privacy and simplifies the morning routine. The ground-floor bathroom integrates naturally into the social area, helping the home function smoothly even when shared by multiple occupants.

Natural light and glazing designed for comfort

Natural light is one of the project's defining features. Large windows flood the living areas with daylight, helping the 50 m² interior feel more spacious. According to the manufacturer, PVC windows with triple glazing, available in white or anthracite finishes and fitted with stainless-steel hardware, can be specified as an option. This solution is designed to improve thermal comfort year-round while enhancing acoustic insulation.

Making natural light a central feature is about more than aesthetics. In compact homes, brightness expands the perceived space, illuminates areas that might otherwise feel enclosed and supports everyday activities without constant reliance on artificial lighting. In addition, the dark exterior finishes, combined with the warmth of the wood, create a contrast that emphasises the glazed openings and reinforces the home's contemporary character.

A porch that extends outdoor living and can be expanded

The KAYA 4L extends its living space outdoors with a porch large enough for outdoor furniture, designed as a comfortable shaded retreat. It's a simple but effective feature that provides space for outdoor breakfasts, reading or entertaining guests without reducing indoor living space. According to the model specifications, the porch can also be expanded by an additional 7 m², offering extra usable space without altering the interior layout.

As a result, the transition between indoors and outdoors feels seamless, turning the porch into an additional living area for much of the year. The visual connection between the living room and the outdoor space, enhanced by the large windows, helps the home feel larger than its actual footprint and adds flexibility for social gatherings or quiet relaxation.

The multipurpose room that adapts to your needs

Upstairs, alongside the main bedroom, is a multipurpose room. This space is the model's wildcard feature: it can serve as a home office, playroom or additional bedroom whenever required. In compact homes, the difference between feeling restricted and feeling comfortable often comes down to having flexible spaces, and here one of the most attractive areas of the home has been dedicated to that purpose.

This adaptability is valuable both in everyday life and when hosting guests for short stays. A change of furniture, a new layout or the addition of a spare bed is enough to completely redefine its role. Because it is separated from the main living area, it retains a sense of calm even when activity continues downstairs.
