"There is food, refreshments and restrooms near by, however there will not be any of these onsite". About straw/clay building: Light straw/clay walls are built by combining loose (not baled) straw, local clay, and water together and lightly packing it inside a light weight wood framed wall 6-12 inches thick. When the loose straw is combined with the liquid clay, it coats the straw in a protective mineralizing coating, which adds longevity to the fiber, acts as thermal mass and regulates indoor air quality, humidity and temperature. After the walls dry, they are plastered using natural plasters inside and out. In addition to being an up and coming natural building technique worldwide, this technique is a traditional “infill” for German timber frame structures (many are 500 years old + and still occupied). Recently a code supplement was accepted into the IRC (International Residential Code) for light straw/clay building.

Joseph Becker is a passionate ecological builder, educator and owner of ION Ecobuilding. He spends much of his working time with owners, builders and communities in collaborative ecological building projects, specializing in local, natural, and least toxic materials, energy efficiency retrofits, and traditional building systems (including earth, straw & lime). Joseph’s ultimate hope is to reinforce a sense of place and enhance the world where we live, by working together and participating in that which sustains us.
