Honestly, this would be a really cool way to build Cobb houses, which are very environmentally friendly, have fantastic insulation, and are some of our oldest still standing structures, iirc. Good hat and boots (roof with overhang and foundation), 3d printed Cobb walls, and a lime coating, and I could see this really making housing costs a lot lower in certain communities.
Biggest downside to Cobb from my research is just that electrical and plumbing typically needs to be running conduit on top of the wall, instead of inside the wall, if you want the option to upgrade or change it later.
