Come and join us in beautiful eastern Tennessee for our next Introduction to Cob and Straw Workshop! We will be constructing both a cob building and a straw-clay building. This workshop is perfect for beginners and experts alike! You will get the expert knowledge to build with cob and straw! Either for small-scale structures or large-scale projects like homes and buildings.
This workshop is a great experience to learn how to build with cob and straw, and to get a broad learning overview of natural building techniques. You will get a solid foundation in natural building fundamentals. You will learn the advantages of high thermal mass cob versus high insulation straw materials. We will be constructing the walls on a new cob building and a straw-clay building, mixing and applying lime plaster, and studying Natural Building together each day. You will also get to see living examples on-site of a completed cob building and straw-clay building. These are excellent examples that you can learn a lot from! After this workshop, you will have the basic experience and confidence to design and build your own cob and straw constructions or buildings.
Hands-On Work Topics:
– How to make cob (learn how to make cob with the tarp method and with machinery)
– How to build cob walls using traditional hand-sculpting and using innovative slipforms (learn all the great advantages of building cob walls with forms)
– How to make straw-clay (also known as light-straw-clay)
– How to build highly insulating straw-clay walls (learn how to frame and pack the walls)
– Selecting and testing soils for cob and straw-clay (learn several ways to test your soil composition)
– Lime Plaster Finishing (learn how to mix and apply lime plaster finishes to your walls)

– Building codes and how to successfully get building permits for cob homes and straw homes.
– Best practices for building a healthy, non-toxic home.

This workshop is a unique experience for people to learn about building cob homes and light-straw-clay 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 and strawbale 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 Greeneville, 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, straw, and natural building topics. We will break for lunch between 12:00 to 1:00 PM, and we will complete each day at around 4:00 PM. They will be full-packed days! Worth your every penny!
Teacher
The workshop will be taught by Alex Sumerall, an east coast Earth Building Mason 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, which is dedicated to teaching people about cob and earthen building techniques. Alex has been practicing earthen 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.
Free Bonus!
Everyone who signs up for the workshop will receive a printed copy of Alex’s book, “Build a Cob House: A Step-By-Step Guide”, and the downloadable PDF version, FREE! We only make printed copies for workshop students, so this is your chance to get one. We will be using the book as a lesson guide throughout the workshop too so you can follow along with your book in hand.
Alpaca Farm Tour!
As another added bonus to the workshop, we also offer a free alpaca farm tour at our neighbor’s Two Roots Farm. They have over 50 friendly alpacas, a fiber mill, and a gift shop! We usually go on this tour Wednesday after class.
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!”
“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!”
