Situated on a hill overlooking Lake Lugano in Italy, this polygonal shaped glass house with round edges is optimized for thermal efficiency. The glass pavilion has two defined areas — mountain view and lake view. The living room, dining room and kitchen are located in the pavilion, while the bedrooms, bathrooms and garage are in the lower underground block. The use of geothermal energy, rain-water collection system and efficient low-emittance glass insulated with argon gas makes this the ultimate energy efficient home.
