This is interesting. The Walter Segal self-build method is another approach that aims to use common materials (lumber, plywood, insulation) with little cutting so as to reduce labor and allow for later disassembly+reuse.

With many of these less common methods it's more work to show safety, code compliance, etc. For example the Segal method doesn't really allow for modern levels of air sealing and insulation.
