#1 Earth Houses - Dieticon, Switzerland

These earth houses are some of the most beautiful underground homes you will find. Built directly into the land, the roofs are covered with grass, but the front faces are very futuristic, resembling pods. Completely energy efficient, they are warm in winter, cool in summer. Very little outdoor maintenance is required.
