Designed by the architects of SeArch and Christian Müller, this home in Vals, Switzerland is hidden in a safe place. By building the house underground, the architects were able to almost completely eliminate the need for heating or cooling in the winter and summer months. One could also book a room in this very unique home at the official website of Villa Vals.
