Robin Skidmore Dec. 17, 2020Last updated: Jan. 6, 2021 My partner and I want to build, live in, and potentially even rent out, an Earthship; a type of passive solar earth shelter that is made of both natural and upcycled materials. My question is where do we start? Who do we ask? Who do we hire? How much money do we need? Any ideas or brainstorms are welcome.
