The multigenerational house on Lake Constance exemplifies a contemporary approach to natural stone. Set on a prominent hillside site, the monolithic volume appears to emerge naturally from the terrain. The consistent use of natural stone reinforces this impression, mediating between landscape and architecture.
The cubic volume derives its calm presence and sense of scale from precisely mitred edges and a carefully planned arrangement of slabs based on a three-dimensional grid. Natural stone is not treated as a surface finish, but as a spatial and constructive element. The continuous use of the material unifies walls, floors and staircases into a coherent spatial surface, while the meticulously defined joint pattern underscores the geometric precision.
The organisation of the house responds to contemporary ways of living. Two residential units are linked by a garden room that serves as a shared space for gathering and circulation. The architecture supports communal use as well as clear separation: the units can be combined or used independently, while maintaining a high degree of privacy despite the limited floor area.
Precisely positioned openings and threshold-free transitions connect interior and exterior, integrating orientation and expansive views directly into the spatial sequence. Ceppo di Gré natural stone defines both the interior and the exterior. Its conglomerate structure is reminiscent of concrete and complements the exposed-concrete surfaces harmoniously. The deliberate contrast between rough, open-pored natural stone and finely honed surfaces creates variety despite the restrained material palette.
Construction details such as parapet copings, balustrades and window reveals with inward slopes, together with integrated drainage channels, minimise signs of weathering and make the material's durability tangible. The multigenerational house demonstrates the potential of natural stone as a precise, innovative and sustainable building material.
