Learn to build your own energy-efficient home from inexpensive, healthy natural materials. In this hands-on workshop, we will be building a family home from cob (sculpted earth) and straw bales. We will also experiment with other natural wall systems including slipstraw or light straw clay, as well as clay plasters. Daily lectures will cover materials selection and testing, passive solar principles, and other aspects of designing and building a hybrid natural house. Slide presentations and videos place these techniques in context of the global tradition of natural building. More info.
