One-Day Cob Primer
Every Saturday in May
Jacksonville, Oregon

Join us for a day of learning, mixing materials and seeing all the things you can do with earthen construction. This day is a perfect introduction to building with earth for those who are considering building a house or a cottage, or for those who are thinking about using these techniques to remodel their existing home. You'll get hands-on experience in mixing cob and building a section of a wall with it. We will also demo how to install an earthen floor or how to apply an earthen plaster on just about every possible material, from straw bales to drywall. The light straw-clay technique will show you how to remodel an existing home (or garage) and also will give you some tools to start a new construction project that can be code approved.
