I’m hoping to build a bale cob home on my property once I get the land filled in the next two years. I was originally thinking of doing a concrete foundation, but someone mentioned that I should do an earthbag foundation. I love the idea, but most of the earthbag foundations I’ve seen are a smaller dome type and are fully earthbag houses. I live in a colder climate so I’m planning on going with bale cob for some extra warmth in the winters. My current design has my house being 25 feet by 20 feet and a second story of 10 feet by 20 feet. I want my house to outlive me so I want to make sure I pick the best foundation for it. Does it sound like an earthbag foundation would work or should I switch my gears back to concrete?
