This 1,378 sq ft concrete vacation house situated in Gambarogno, Switzerland, was designed in 2015 by Wespi de Meuron Romeo Architects.

Description by Wespi de Meuron Romeo Architects
The house, designed as a residence for a family of three persons, was built in the immediate proximity of the architecture office in Caviano on the Lake Maggiore.
In terms of adequate architectural densification new living space should be created on a remaining area of just 128 m2 (1,378 ft2), on the same plot as the architecture office was built in 1981, without damaging the existing qualities. On the contrary, an enrichment of the outer spatial situation should be generated with reasonable densification in context with the existing building. The building laws determined the outer form of the building, what often happens when leftover plots are developed. The minimal distance to the road, the minimal distance to the forest, the minimal building distance to the architecture office as well as the right to build on the limit to the southwest neighbour, create an irregular pentagonal form of totally 79 m² (850 ft²) surface. A clear rectangle of 48 m² (517 ft²) surface, which is the isolated interior, was integrated in this irregular form.
The polygonal exterior shape and the steep topography of the site let the building appear as an archaic stone block in middle of the forest, this is reinforced by the rough washed concrete surfaces becoming darker by the weathering.
