A small "underground home" built in the style of Oehler, as only a simple, non-waterproofed hole in ground with simple planks and a plastic sheet to a wall, despite using free labour (ignoring the opportunity costs of not having time to go to work) and recycled materials, e.g. windows and planks for the wall, is estimated to be 30% cheaper to ...
