The idea of the project was to rebuild a single family house from the 1960’s located at the edge of a wood into a three-family house. Despite the doubling of the living space the entire garden area could be preserved. Therefore both the founded building parts protrude as a pure wooden column-free construction up to 5 m above the estate. By means of using entirely high insulated cover with a silver fir shade and modern installations with a controlled building ventilation the heating need could be even reduced, and this despite the doubling of the space. The idea of a modern three-family house as an concentrated living form represents - particularly in the scattered settlement area of Vorarlberg - an exemplary alternative to a detached one-family house.
