About an hour and a half outside Los Angeles in Hespiria, California is Cal-Earth. You will be amazed at these Super Adobe type structures built mostly of Earth. They are open to the public the first Saturday of every month.
What Cal-Earth is doing is amazing. It was founded by Nader Khalili, an architect, lover of Rumi Poetry, and someone who worked hard to get the word out about inexpensive shelters, he called Eco-Domes.
*Stock Plans have been approved in Hesperia City and San Bernardino County.

Bask in the simple beauty of Nature and the natural poetry of Nader Khalili.
With the ever more increasing costs of fuel and heavy loss of trees already, it is necessary to learn alternative ways of living with the Earth. Creating a home from the Earth with a few other materials saves our resources and makes alot of sense. They offer training and apprenticeship courses.
You get a feeling of peace and well being moving from room to room.
It is a very interesting contrast when you drive in, because you end up driving through a new mini subdivision of houses (a single street) to get to the dirt road and parking for Cal-Earth. Our guides were truly kind and knowledgeable people. There was a pot-luck lunch (bring something if you like). —Teri Hitt

— A pile of earth, dug out from the building site, is turned into a small house called Eco- Dome (moon cocoon model), using the Superadobe technology. It documents how professionals and students from many countries training at Cal-Earth Institute built this structure. It is intended for use with materials and tools developed for instruction during the apprenticeship retreat at Cal-Earth. Superadobe technology was first presented by the architect to NASA for lunar habitats, and can build single or clustered homes on earth which are resistant to fire, floods, wind storms and earthquakes.
