The ground floor of a 1950s house is being reorganised. The existing floor plan is retained. A new volume is added, pushed against the rear of the house, creating a patio between the extension and the living space inside. The extension is conceived as a freestanding roof structure resting on four slender steel columns.
The timber structure consists of four interlocking main beams that form a central rooflight. Where the extension touches the outdoor space, it is bordered by folding window. The garden wall continues inside, leaving only the feeling of an open canopy in summer. Expansion profiles in the polished floor show the force action between the columns.
