Timber Frame Prefabricated
House with Usable Attic – 110 m²
Prime House 110
Prefabricated House with Usable Attic
Prime House 110 is a prefabricated house in the modern barn style, designed for a family of four. The layout includes a spacious 32 m² living room with a kitchen annex, four well-proportioned rooms, two large bathrooms, a utility room, and a vestibule.
Storage areas — often neglected in traditional projects — have been given particular attention. The house features a spacious vestibule with space for built-in wardrobes, a utility room, a storage area under the stairs, and multiple recesses and alcoves designed for additional storage.
The building complies with the technical standards set by the WT2021 regulation. It is a year-round, energy-efficient residence, fully meeting the requirements for a full building permit.
As this house includes a fully usable attic, it cannot be built under notification as a recreational building (BRI). Construction of homes with a usable attic requires a full building permit or notification as a residential building (with full architectural plans).
Purpose
Our modern barn-style house is an excellent choice for permanent residence for a family of four. The house layout divides the living zone on the ground floor from the sleeping zone on the upper floor. The thoughtful design ensures everyday comfort for the residents, while large custom-designed windows allow for beautiful panoramic views.

Functional Living Space
The house provides everything needed for year-round living: a spacious kitchen and living area, three bedrooms, two bathrooms, a home office, a vestibule, and a utility room.
The utility room accommodates a washing machine and allows for the installation of larger technical equipment, such as a water softener, pressure booster system, water heater, or heat recovery ventilation (HRV) system.
The open-plan living room with kitchen on the ground floor is the heart of the home — a space for daily life and family gatherings. The inclusion of a fireplace adds warmth and character, reinforcing the spirit of home.
The upper floor, dedicated to bedrooms, ensures privacy and tranquility while offering stunning views through the large panoramic windows.
Top-Quality Materials
The facade of our house is finished with spruce cladding. The roof is covered with modular metal roofing tiles. The window joinery includes six-chamber, triple-glazed windows, installed using the warm installation method.
The main insulation of the house consists of mineral wool or, optionally, Steico Zell blown-in wood fibre. The house is additionally insulated with Steico thermal insulation boards.

Robust structure built using German heavy timber frame technology
We build our walls using certified KVH structural timber, finger-jointed and glued, with a cross-section of 60 x 160 mm. This timber contains 47% more raw material than standard Scandinavian beams with a 45 x 145 mm cross-section. The more massive wall structure significantly improves the building’s statics and the mechanical performance of structural joints.
Additionally, instead of standard gypsum plasterboard, we use Fermacell gypsum fibre boards as the interior wall finish. Fermacell boards are twice as dense and therefore significantly harder than standard plasterboard, which greatly improves the building’s structural performance and fire resistance. These boards are also moisture-resistant, making them suitable for wet areas.
Our German heavy frame construction system, combined with double wall stiffening using Fermacell and MFP P5 boards, ensures that our buildings meet the requirements of Poland’s highest wind and snow load zones as standard.
Vapour-open construction in accordance with building physics
The walls and roofs of our houses are additionally insulated with 6.0 cm thick Steico insulation boards. This results in a total wall insulation thickness of 27.0 cm [Uw = 0.135 W/m²K] and roof insulation of 30.0 cm [Uw = 0.126 W/m²K]. These boards significantly improve the thermal transmittance coefficient (Uw) of the building envelope and, due to their high specific heat capacity (Cw), also protect against overheating in summer. Additionally, they enhance acoustic insulation.
As a result, our homes qualify as premium in terms of both energy efficiency and soundproofing. Wood fibre boards are vapour-open materials that can be installed on the exterior side of the structure. Unlike polystyrene or OSB boards, which block moisture escape when placed on the exterior, wood fibre boards allow for proper moisture diffusion, significantly extending the life of the structure and preventing mould and mildew growth.
Installation Cavity for Electrical and Plumbing Systems
The installation battening we use on the interior side of the walls serves as a dedicated space for mounting electrical boxes, running cables in conduits, and concealing water pipes. This additional installation cavity is designed to protect the vapour barrier from being punctured.
Failing to use an installation cavity—and instead embedding installations directly into the main wall structure—leads to puncturing the vapour barrier. This allows water vapour to penetrate the structure and the main insulation layer, ultimately degrading the wall system and contributing to mould and mildew growth within the building.
The installation cavity eliminates this issue by preserving the continuity and airtightness of the vapour barrier, as all utilities are placed within the secondary battening layer. This cavity also provides an additional 5 cm layer of insulation.
Thanks to this wall system design and the high quality of materials we use, we confidently offer a 30-year warranty on the structural integrity of our homes.
