Cal-Earth, California

The California Institute of Earth Art and Architecture (Cal-Earth), promotes and explores the use of simple, earth material for building construction, such as adobe and ceramics. Based on the principles of the architect Nader Khalili, known for his ceramic buildings which are fired in place by turning the raw structure into a sort of kiln, and for a continuous, tubular sandbag building material called Superadobe or Superblock. The institute offers public programs and apprenticeships, and sits on seven acres of desert land outside Hesperia, near Victorville. There is a Khalili-designed dome located at a museum in Hesperia.
