Prefab house / contemporary / wooden frame / with terrace
100 m² (1076.39 ft²)
This project was based on a typical single-family house built in 1956. The ground floor living area was 80 sq. m and the top floor living area was 58 sq. m. The parents of the young developers had transferred the property to them and they wanted to turn it into a modern two-generation house. The aim was to create a living space for the parents on the ground floor and space for up to four people on the top floor. The structural circumstances were ideal for the use of an innovative timber frame construction: a cube-shaped extension directly on the roof. The wooden beam ceiling of the old house was reinforced in terms of statics and building physics, thanks to our HBV system upgrade.
The new living space ceiling over the carport was designed as an HBV plate floor. This was used to reinforce the entire building. An energy-related upgrade was also carried out entirely in line with KfW standards, including insulation between the rafters and ETICS insulation in the walls. The new cube building is now used on all three levels: on the ground floor, the new HBV plate floor has been used to create a carport for two cars. On the top floor, the living area was extended from 58 to 100 sq. m and the roof of the cube is also used as a roof terrace. The innovative concept was rounded off with horizontal facade cladding made from larch wood, giving the cube a modern look.
