Following the example of Walserhaus (1) a massive plinth, on which the wood construction rests, protects the - in a well-known Swiss ski resort - mountain house. The operating elements such as the inner access, the kitchen and wet areas are situated within the massive mineral base structure of the house, while the attending rooms such as the sleeping and living areas inside and outside are fully formed as larch wood construction.
Following the slope, the rooms are spread over 5 half-levels and form a continuous sequence, which provide the residents specific references to the surroundings on all levels, and common as well as individual retreats. The high spatial concentration and the many solid joinery structures are reminiscent of a houseboat.
The free layout of the interior spaces could be realized thanks to a free-hanging ventilated roof structure: the lower roof hangs, and the copper roof bars are superimposed on the outlying wooden bays, which are composed of mullions and wooden beams.
The beams of the bays hang in the middle on a steel frame spanning the entire length of the building.
The supporting framework also includes the existing double-shell exposed concrete, corresponding to the gradient stepped plinth that develops inside as access zones to the top floor. The exposed concrete surfaces were water-blasted at different processing levels with the maximum pressure to assert the grain size of the exposed concrete as a monolithic body.
The entire structure is recognisable from the outside and has been meticulously integrated into the façade design. The self-supporting, only selectively connected to the primary wood structure, wooden façade could be brought to a single plane thanks to a high performance interior and exterior insulation with sliding windows.
