Listen to the great things that our workshop participants are saying!


“The cob workshop was a life-changing experience. I learned a lot about natural building, not only from Alex’s instruction, experience and demonstrations, but from interacting with people from different backgrounds who were a great source of collective knowledge. The hands-on experience was priceless!”
Tony Romo, Texas

“The Cob Building Workshop was a great investment of my time! It was well organized, extremely inspiring, and FUN! Alex was able to explain construction basics to neophytes like me, yet he could also answer the complex questions asked by the more experienced workshop attendees. I can’t wait until the next workshop!”

Marybeth Babos, Tennessee
