Cal Earth

2015 Superadobe Intensive Workshops

Education and training are essential to Cal-Earth's vision. We believe that shelter is a basic human right and that every person should be able to build a home for him or herself. For those interested in learning to build with the earth, Cal-Earth offers intensive workshops throughout the year. Give us a few days of your time and we will teach you hands-on how to build your home, your school, or your community with the earth beneath your feet. The Superadobe Intensive Workshop is offered in two formats: the regular week-long which includes the full workshop curriculum, and the abridged 4 day program offered annually in February, July and November.

What happens during a Cal-Earth Workshop?
These are hands-on workshops for people who want to learn to build from earth and the elements. The workshops give the chance to focus on learning the unique Earthbuilding (Superadobe) techniques developed at Cal-Earth as well as traditional earth building techniques, in the serene and instructive setting of the Cal-Earth prototypes. Teaching methods are in the tradition of Nader Khalili with philosophy, design theory, and priniciples taught through the expresion of the hands-on experience. Thousands of students have gone through this unique program, many of whom have gone on to build all through out the world.

"If you find yourself at a Cal-Earth workshop it is because you have a dream, a passion to learn. In one week you can gain skills and network with people to give your dreams real shape. For this reason I think the workshop was stellar. Led by fabulous and wise instructors, I was able to make with my hands and my new friends the images I saw on the website. I gained confidence that even I can do this and I can continue to dream." -Cal-Earth Workshop participant
