This "underground house" was designed by Swiss studio Bearth & Deplazes in Mergoscia, Switzerland. Description by Bearth & Deplazes: The an­ti­thesis to a house on a slope: one in a cav­ern, or bet­ter yet: a house in a for­ti­fied cav­ern, which is more of a re­in­force­ment of the steep vine­yard, a type of primal ar­chi­tec­ture or ar­chi­tec­tural ar­chae­ology.
