For an apartment building in Baden, we designed a cubic solitaire on a narrow, triangular plot on a slope, which defies the architectural context and anchors itself in the slope. There is no staircase; instead, three apartments are stacked in such a way that they each have their own entrance. Each apartment is based on a cruciform basic structure, which is, however, individually interpreted: On the ground floor, a family apartment with a large kitchen, terrace and garden is laid out. Above is a loft apartment with a magnificent view to the Limmat Valley, and the attic apartment is based on a room-to-room principle with an internal private patio.
