4 Day Cob Workshop

Cob Building Workshop

A Natural Building Course August 8-11, 2015

Note:  The original course was scheduled for June, but due to unforeseen circumstances we had to cancel.  The new dates coincide with the first four days of our longer 9 day Natural Building Course.

Join us for a four day cob building workshop where art meets function.  Create an elegant garden entrance and gate with us, using cob, stone and wood.  Engage your senses.  Arouse your creativity.  Create a lasting impression.

This workshop will teach you the basics of cob building.  Cob is an ancient method now revised and improved upon with modern development.  From design to construction, you will participate fully, while expressing yourself and your inner artist.

Cob is a mixture of sand, straw and clay.  This mix is made into loaves or lumps, which are then used to build walls.  Cob is virtually free form and is akin to sculpting.  By using this cheap, locally available, healthy and creative medium we can create garden walls, benches and even houses.  Although house building is a more advanced skill, building small structures with cob is something that most everyone can do to add beauty and function to their landscape.  Building with cob is fun, muddy, encourages community building and is an empowering process.  People of all ages can participate.


Andy Sahn – has devoted his life to the field of sustainable development in construction, agriculture, and ecological design. Beginning in Israel at Ecovillage Kibbutz Lotan, Andy received a premier education in sustainable agriculture, natural building, ecological design & social justice, and earned his Permaculture Design Certificate.
Inspired and reborn with a new sense of awareness, he continued on traveling across the U.S. learning & developing his skills. In 2011, Andy apprenticed at the North American School of Natural Building, in Coquille, OR,  where he studied with builder, philosopher, inventor, Ianto Evans. He then went on to work with many other natural builders and has taught workshops in Austin, Tx, New York, Oregon, Tennessee, and Mexico. Andy’s passion to educate people about the ease of building with earth and the wealth of other local, minimally processed materials, has helped empower many others interested starting in their own projects.  He is the owner/creator of Earthen Home Designs in Nashville.
