The project
Due to the building's playful floor plan, various challenges arose for the supporting structure. However, with a close cooperation between the timber constructor, the civil engineer and the timber engineer, all of them could be mastered and the client could enjoy an unique building. Burkart trilegno AG decided to bring the timber engineer on board immediately. This way, the details of the engineer and the timber constructor could be developed together from the beginning, minimizing the effort on both sides. At a later stage, Timbatec's building physics department also supported the architecture in matters relating to summer thermal protection.
The construction
The majority of the interior walls and all exterior walls were constructed as timber frame elements. In some cases, cross laminated timber panels were used as wall panels to stabilize the concrete rear wall of the building. The floor slabs and the roof were constructed as hollow box elements. The box girders for the garage roof had to be planked with laminated veneer lumber to bridge the nine-meter span.
The challenge
A nine-meter wide sliding door was used between the living area and the balcony. The roofing of the balcony was made using three solid glulam beams and closed over the entire surface with a CLT panel. The girder above the sliding door was additionally heightened.
