This small larch barn in the valley of Bagnes, Wallis in Switzerland, combines rustic architecture with state-of-the-art sustainable technologies. Now an energy-efficient home for a couple, the barn was renovated by Alp'Architecture sàrl, becoming the first building of its type to be certified with Minergie P, a quality label for new and refurbished low-energy buildings in Switzerland and Liechtenstein.
The small house was extended at the back, with volumes added so that the existing structure could be transformed into a primary residence for a couple. An entire new volume was added on the ground floor, housing a garage, a bathroom, equipment rooms and the entrance. The extension is partly visible on the first floor, where its contemporary cladding distinguishes the addition from the old barn.
Adequately sized openings frame particular views of the valley, while new furnishings utilize every inch of the available space. In order to meet the requirements for the Minergie P certification, the architects introduced solar panels and double flow ventilation, which were a challenge to integrate into the existing architecture.
