The house we are building will be a home to a family of four: Mom, Dad and two young boys. The task at hand is to build a solid cob wall around an existing yurt structure and to build an additional room on the side to serve as the parent’s bedroom.
When building with cob, it is best to build along the whole perimeter of the building at once. When cob walls dry, they become a monolith, like one giant house-shaped rock, really! I’ve read about this in “The Hand Sculpted House” book, but I didn’t really comprehend this until I mixed my first batch of cob and made a test brick. Once it dried, neither smashing it nor throwing it affected its brick-ness. No words to describe this phenomenon, only a personal experience of dried cob.
But let’s start at the beginning, and any self-respecting house begins with a solid foundation.
