Clay house Rauch

The Rauch residence is a model of modern earthen building. It was designed and built by the earthen building pioneer Martin Rauch and the architect Roger Boltshauser. The house has grown directly from the slope, because for its construction was used mainly the earth from the excavation.

The exterior walls consist of 45-centimeter-thick rammed clay walls. Several layers of earth-moist clay were poured between a pressure-resistant formwork and compacted with pneumatic rammers. Walls in contact with the earth are sealed with bitumen and foam glass insulation, the remaining wall surfaces are untreated.
