Description
The building site is narrowed by the two adjacent buildings that reach deep into the courtyard. The new building is set independently into the courtyard; its sides are concave to make the gap seem larger. This unusual structure was made possible by an exception in the building code (for architectural ensembles).
The apartments on the third and fourth stories, above store and offices, each occupy one half of the longitudinally divided building. The living rooms open up to the east, to the street; bedrooms face the courtyard to the west. The open kitchens in the center of the apartments are lit through glass-brick walls. The rooms are connected by a minimal hallway along the curved outer wall. Each of the fourth-floor apartments has a rooftop terrace.
