The crown jewel of architect Michael Reynolds’ sustainable vision, Vallecitos is a passive solar home within the Greater World Earthship Community, the world’s largest, legal off-grid subdivision.

Embedded in the environment of Taos, New Mexico, Vallecitos boasts two bedrooms, two bathrooms and a two-car garage, plus a 1,000-square-foot garden, floating deck and panoramic sauna. It’s listed for $825,000.

John R. Johnston of BHHS Taos Real Estate is representing this property, as well an artist’s passion project, also in Taos.
