The House of the Ungar in Wiggensbach was for Architect Rainer Hoffmann and Architect Peter Fakler a challenge because it had to be implemented with a minimum budget of 240,000 €. It was also the first project realized by his own studio.

The view is an essential element of the design. The south facade, completely in glass, opens to a mountain scene. The other sides are closed as much as possible. The second dominant design principle is the reduction. It resulted partially from the limited budget and from the desire of the client to live in clear minimalist forms. The garage closes a three-sided protected courtyard, a transition zone before entering the house. In the underground there are rooms for three children and one guest. The groundfloor is the living room for parents and common area. The balcony is inline with the entire south facade and is protected by the overhanging roof, therefore expanding the living area to the outside. The foundation floor is a steel-concrete construction with stacked walls in wood frame construction (large prefabricated pieces) highly isolated.
