Lowtech Graph lists low-tech options for every need of a home. Here you can compare them, find tutorials to build them, and link them together into a circular system. Why low-tech?

Compressed earth block (CEB) walls: Machine- or hand-pressed earth blocks laid like masonry; faster to build than cob, similarly low embodied energy.
Rammed earth (pise) wall construction: Damp earth rammed hard, layer by layer, between temporary wooden boards, which come off to leave a solid earth wall. The thick wall carries the roof and stores
