the tracuit mountain hut (altitude 3256 metres) belongs to the chaussy section of the swiss alpine club and is situated in the val d’anniviers, in the heart of the valaisan alps. its superb position makes it the ideal starting-point for climbing the bishorn and the weisshorn. the nature of the site, between a cliff and a glacier, defined the position and shape of the new hut, which is constructed along the ridge above the cliff. the south façade of the building extends from the cliff and works like a large solar collector. the other inox-facades reflect the surrounding landscape. the wood-structure was chosed beacause of the difficulties of transportation. the concrete is limited to the plantings.
