is a minimalist house located in Passau, Germany, designed by . The polygonal, multi unit house was built within six months as an KfW 70 Standard house. The concept for the building provides the strict separation between living areas and utility areas. Towards the street the house presents itself very introverted and closed. This part of the house holds the staircase and utility rooms, it is built out of concrete and differs itself in material and aesthetically from the rest of the building. The house is also built on a concrete base, that way the building is not only flood-proof, the concrete base holds parking spots as well.
