The Silberfisch

Clean lines and atypical angles make this zero-emission home in Oldenberg, Germany rather arresting. Eco-friendly attributes include rain barrels, hemp and wood insulation and a water-saving toilet. Since living at sea shouldn't mean you don't have some greenery, the designers added a rooftop terrace that functions much like a lawn. Large front windows not only offer panoramic views, but also allow light to reflect off the white minimalist interior.
