Peeking above the city skyline in Stuttgart, Germany is a contemporary single-family home that efficiently uses space and materials. The roof of the home, designed by w67 architekten bda schulz + stoll, is multi-purposed as a roof-top terrace, which adds functional space and wonderful views from atop the glass and concrete box. Underneath, a slim structural column gracefully supports the front of the home, which rests on a steep hill. [via archidose]
