I’m been saying for quite a while the easiest, fastest shape to build with earthbags is a roundhouse. Build one roundhouse and then add on later if you want to avoid debt. Adding a connecting space – two straight joining walls as shown above — is a simple solution for joining roundhouses. This simplifies roof construction since standard trusses can be used. Other options include reciprocal roofs, pole frame, etc. Using the connecting space as a greenhouse is ideal so you have at least some organic home-based food production nearly year-round.
