Neat Hobbit House. I like the idea of having a natural earth berm as a house wall. Great concept. I wonder if we have too much rock on our property to do the same. We have a hill tall enough to accommodate a two-story house with one floor below ground level. If anyone else looks at the house and has pictures, please post them. I'd like to see more of this kind of house. We toured the earth ships in Taos, NM, a few years ago. DH didn't like the rammed earth/tire wall concept. He's more of a concrete kind of guy.
