This workshop is a unique experience for people to learn about building cob homes and to get an overview of Natural Building. Not only are there plenty of hands-on lessons to learn from, but we will also have ample discussion and informal classroom time. Most cob workshops don’t cover this many topics. 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 Jonesborough, Tennessee.

Each day will begin at 9:00 AM, and the days will include hands-on building, classroom sessions, discussions, and learning activities related to cob and natural building topics. We will break for lunch between 12:00 to 1:30 PM, and we will complete each day at around 4:00 PM. They will be full-packed days! Worth your every penny!
