Miguel Elliott has been a leader in the natural building movement for over 20 years. He started his Sonoma County based business/service Living Earth Structures in 2008 after spending years travelling around the world developing his skills and being inspired by different methods of building. He was knighted as “Sir Cobalot” with a special ceremony when he proclaimed his commitment to promoting natural building. He deeply believes in the importance of Earthen building and works to create opportunities for community involvement.
The Mission is to construct high quality living earth structures, such as cob benches, wood fired ovens, and adobe dome saunas encouraging community involvement through educational workshops and gatherings around the finished project, promoting a healthy, simple and creative lifestyle harmonious with the natural flow of creation. After spending over ten years of natural building in countries ranging from Argentina, Guatemala, Africa, Thailand and around the US, Miguel Elliott aka “Sir Cobalot” has brought his skills to his hometown of Petaluma, California, a town with a rich history of natural adobe building. Inspired and fascinated at an early age by the earthen ovens at General Vallejo’s old adobe home in Petaluma, Miguel now finds himself specializing in creating various living earth structures such as cob benches, cob ovens, adobe dome saunas and small huts. Miguel spent nearly 4 years at the Isis Oasis Retreat center in Geyserville, where he built the Hobbit Hut, Gingerbread House, and several other cob structures around the property.

We have been working to get our Palletable Cobin designed to meet code. At this point, we have an engineered drawings to have both a round and rectangular structure designed to meet code requirements. We have a 160 sq ft designed that can be built as an Accessory Dwelling Unit (ADU) it is built with a post and beam frame with pallets attached to either side of the studs, insulated with straw, and then covered in an Earthen plaster. The design includes space for a bathroom and small kitchenette. We are currently taking orders to build a backyard ADU. Once we get an order to build, we would submit the plans to the Building Department to get a building permit for the unit, complete with electricity and plumbing permits. The cost estimate for an ADU would be about $30,000 complete with the required poured concrete foundation, insulation, double paned windows, roofing and framing materials.
