Design: The new Sasso Nero mountain hut is a tall standalone structure nestled into a natural depression at an altitude of 3,026 meters above sea level. With its appearance of a monumental rock, it seems to have been shaped by the glacier landscape, the wind and other harsh weather conditions. The sloping facade clad in copper sheets hides a solid timber frame construction with six floors, set on a two-level concrete base where the hut meets the mountain. Despite its remarkable appearance, the building fuses with its rocky environment.
Wood: The construction material was cut in the vicinity and processed and prefabricated by local carpenters and joiners. The interior is dominated by refined face quality grade timber – as seen in the restaurant, with a minimalist interior finishing and furnishing made of spruce from the local area, allowing for a spectacular panoramic view of the surrounding mountaintop landscape.
Energy: Thanks to the insulation properties of the construction material used here, the heating energy demand of the building is only 13 kWh/m²a despite the extreme altitude. The demand is met with solar collectors and a block-type thermal power plant.
