This workshop will have plenty of hands-on lessons to learn from, and we will also have ample discussion and informal classroom time.

There will be many live examples of Natural Building methods on site for you to learn from too!

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!

“Alex’s 5-day Cob Garden Wall workshop in May 2014 was my first experience working with Cob and it was very rewarding! He is very knowledgeable and offered alternative solutions during any “cobtastrophes”. With many hours of hands on training opportunity I am confident and well prepared to begin working on my cob home sooner rather than later. Alex’s workshop was much more than I expected and worth every penny!”

– Maria Wilbur, Virginia

The workshop will take place in Murfreesboro, Tennessee on a beautiful 48 acre property. There are fields, streams, a horse ranch, outdoor pavilion, and swimming pool! It’s the perfect place for a workshop. You will feel like you’re on vacation at a resort. We can work hard during the day, take a dip in the pool afterwards, and then rest and relax on the property in the evenings.

We will begin each day with breakfast at 7:00 AM, discuss cob and natural building topics, and begin work around 8:30 AM. We will break for lunch at noon and return to our projects at 2:00 PM. We will complete hands-on work around 5:30 PM. We will serve dinner at 7:00, and complete the day with more classroom discussions or natural building presentations. They will be full-packed days! Worth your every penny!

The workshop will be lead by Alex Sumerall, an up-and-coming east coast Natural Builder who has a focus on creating earthen structures that are healthy, aesthetically pleasing, and functional for modern life.
