20 Homes That Are Habitats

20 of 21

With planted roofs and vertical timber siding, the Mill Valley Cabins have been crafted to look and feel like a natural extension of the surrounding forest canopy. Designed by Feldman Architecture the two structures—one serving as an artist studio and the other as a place to practice yoga—sit lightly on the land and take cues from the existing topography. The 500-square-foot artist studio is located higher on the slope, and overlooks the green roof of the 415-square-foot yoga studio below.
