About clay/straw building (Light Earth or Leight Lehnm in Geman): These clay/straw walls will be built by combining local clay, loose (not baled) straw and wate together and packing it inside a 2x6” wall. This technique is a traditional “infill” in German timber frame structures (many 500 year old + and still occupied) and is now having a resurgence workldwide. The loose straw is combined with the liquid clay, coating the straw in a protective mineralized coating, which preserves the fiber. After the walls dry, they are plastered using natural plasters inside and out. We are also creating a “Super Insulated Earth” Hybrid wall by wrapping the clay/straw walls with 3” of exterior, continuous insulation
