What is SuperAdobe?

Using sandbags, barbed wire and the earth beneath your feet, SuperAdobe is a truly affordable and sustainable way to build homes anywhere on the planet. SuperAdobe combines ancient building techniques with basic architectural principles, and the results are earthquake, fire, and flood resistant structures that can range from a one-person pod to a fully modernized home.

Our Founder

Nader Khalili

Nader Khalili (1936-2008) was a visionary architect, author, humanitarian, teacher, and innovator. Inspired by the poetry of Rumi, he was a quiet hero who never forgot the importance of living an honest, meaningful life. “No one can prove there is a meaning to life. I must make my own life meaningful. That is all.”

"You transform all those who are touched by you."

- RUMI
