Three new stories were placed on top of a three-story corner building dating to the Gründerzeit. Taking the allowable envelope as point of departure – as specified by the building code – by making cutouts and leaving parts unbuilt, we developed a framework for distinctive apartments and a diffuse silhouette. Consequently, on the top two levels are two-story freestanding houses accompanied by a continuous garden; a two-story apartment with a corner window; and additional distinctively cut apartments with large outdoor spaces.
