This residential building for a family of five is located in the immediate vicinity of two listed buildings that are significant for Bielefeld: the music and art school, an Art Nouveau building from 1913, and the Sparrenburg, Bielefeld's 13th-century landmark. The sensitive location called for a respectful response, which also had to be coordinated with the Office for the Protection of Historical Monuments. With its square floor plan, the residential building extends over four floors. On the lowest level is an underground car park, which disappears into the ground, taking advantage of the topography of the steeply sloping property to the north. In front of it, to the south, are basement and fitness rooms, as well as a granny flat to the west. Access to the building is one floor higher from the north. The living/dining area and kitchen are located on this level. The floor above is reserved for the children's rooms, with the parents' area at the top of the building.
The residential building has a gabled roof. This is rotated 45 degrees to the floor plan, giving the building a sculptural quality that makes it highly distinctive. The façade is characterized by an interplay of open and closed surfaces. The positioning of the windows is determined by the desire to provide as many views of Sparrenburg Castle as possible. The color scheme of the plaster facade is based on the quarry stone of the Sparrenburg. The same applies to the tile roofing.
