But here, you will learn all the core lessons needed to start building from this one workshop!

Plus – there will be many hours of discussions about building cob homes and natural building throughout the workshop. Its a great way to get your questions answered and brainstorm your building ideas!

The workshop will be held at a private property in Keystone Heights, Florida.

We will begin each day with a short discussion about cob and natural building topics, and then begin work around 9:00 AM. We will break for lunch at noon and return to our projects at about 1:00 PM. We will complete hands-on work around 5:00 PM, and complete the day with more class discussions. They will be full-packed days! Worth your every penny!

The workshop will be taught by Alex Sumerall, an east coast Natural Builder who has a focus on creating earthen structures that are healthy, aesthetically pleasing, and functional for modern life. He is the owner of This Cob House, LLC, which is dedicated to teaching people about cob and natural building techniques. Alex has a background in business and advertising, and has been practicing Natural Building since 2011. He graduated from the Aprovecho School of Natural Building in 2013 in Cottage Grove, Oregon, and continues to teach, present, consult, and construct.

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
