Cal-Earth Superadobe Structures Survive Nepal Earthquake

Have you ever heard of homes and shelters being made of sandbags and barbed wire, that can withstand the forces of winds and earthquakes ? Last weekend I had the chance to see how that’s done.

IMG_20150502_130011I’ve always been interested in alternative architecture, and when I had the opportunity to visit Cal-Earth in Hesperia, CA at one of their monthly open-houses, I was amazed and delighted with what I experienced and learned about them. There is so much to say about this organization and it’s vision, the vision begun by Iranian-American architect Nader Khalili.

IMG_20150502_105330Nader Khalili began Cal-Earth in 1991. From the Cal-Earth website, “Born in Iran as one of nine children, his quest was to empower the world’s poor and refugees to build homes using the earth under their feet. Khalili’s son Dastan, and daughter Sheefteh, are now working to carry forward his vision and quest throughout the world. He was a prominent American leader on the value of ethically based architecture, where the needs of the homeless are considered above all else.”

IMG_20150502_125857croppedWhen I began an undergraduate architecture curriculum I went home and told my parents that I wanted to build homes for people who were homeless and/or could not afford the kinds of homes most Americans lived in. As it turned out that path did not open for me, but I did become a social worker, caring about families and their needs. So it is no surprise that I am excited to know about this venture in Southern California that is global in nature.

IMG_20150502_125627croppedThe open house began with a presentation describing the structures, their different functions by size and shape, and the materials and construction methods used in creating quick shelter. A small structure can be made by a team of five to six people within a day. In addition, larger permanent structures, using the same principles of construction can be built that withstand the elements of nature.

She received word that day that 40 superadobe structures of an orphanage in Khatmandu, Nepal  survived the recent earthquake there. Cal-Earth has developed structures that withstand the dynamics of earthquakes, and San Bernardina County California has approved construction plans and permits for homes using the methods prescribed by Cal-Earth.

Although the earth structures were not harmed, other structures are in need of repair, and they are requesting funds for that.

There is such an organic and grounded feeling I have when I enter one of these domes. To me it feels a bit like camping out in a tent, or being in a cave – even a big cave. The openings that are incorporated let the light in and create a very earthy, comfortable feeling to me. The creative possibilities are endless!

IMG_20150502_130250cropped IMG_20150502_130346Anyone interested in learning how to build using the sandbag and barbed wire construction methods can take a class either on-site, or via the internet beginning on May 11, 2015. There are various levels of workshops and training available.

For more information I urge you to visit the Cal-Earth website and visit their page on Facebook – Cal-Earth Institute.
