Black Box House

Towards the street, the house appears closed and compact. The suspended timber façade of vertical oak slats seamlessly integrates the garage door, entrance door, house number, letterbox and intercom system.

Towards the garden, the building opens up with generous glazing. A widely projecting roof creates fluid transitions between inside and outside.

Inside, an open, light-filled spatial structure emerges. The continuous exposed screed emphasises the fluid transition between the spatial zones and reinforces the clear, restrained design.

A key design principle is the deliberate absence of conventional corridors. Instead of purely circulatory spaces, rooms are created with functions of their own — as dressing room, utility room, or even as bedroom and bathroom. The principle of the walk-through room replaces the corridor and opens up varied routes through the living space. As a result, the compact building feels surprisingly spacious and lively in everyday use.

The project was recognised with the “Baukultur Kraichgau” and “Beispielhaftes Bauen” awards.
