I wonder if earthbag technology could help to reduce building costs. Labor seems to be a big factor, but perhaps this could be reduced with the right equipment. Rural homes already need a big hole for septic; earthbags would then just make use of the dirt that's already sitting there, if not for the whole house then perhaps for some part of it.
