Switzerland. Canton Ticino. Gnosca. The sustainable house built by architect Simone Comandini. The structure of the house is made in wooden frame, filled with straw bales and closed by a smooth layer of earth and sand. The construction is based on improving the ecological footprint of the building and for its inhabitants to live in a house with high energy performance. 23.09.17 © 2017 Didier Ruef
