Underground House by EM2N

How does one accommodate a growing family and a much-needed home extension without going to the trouble of getting neighbors’ permission? The architects at EM2N found their answer underground. Haus Gross in Greifensee, Switzerland, looks like a typical house by all accounts. But this modern and inventive design proves that looks can be deceiving. This understated, low-profile house holds a buried treasure in the form of an underground living space. The 721-sq.-ft. sub-grade home addition includes two sunken open-air courtyards leading into the three children’s bedrooms, a bathroom and a state-of-the-art home theater for private film screenings. A two-storey glazed façade lets light flood every corner, above ground and below. And while you’d think this design would mean a lot of stair climbing, the architects let their fun side out to play in this funky design, incorporating a slide to take the kids from the upper ground level down the slope and to the lower deck, which leads inside.
