To take advantage of the beautiful view into the small valley of canton Aargau, the house sits high on the steep hillside property. The access is provided by a garage located at street level and an underground staircase connecting the entrance and the residence. The areas on the ground floor are made of exposed concrete with a pine plywood formwork. Above it a wooden timber construction covered with shingles outside and rough-sawn white fir boards inside evolves. The simple saddle roof is covered with cedar shingles, whose durability exceeds the silver fir and whose color already turns grey after a few months. The building complies with the Swiss Minergie-P Standard - it is a passive house operated by a geothermal heat pump and a room ventilation with heat recovery to preserve resources.
