I have lived in this meadow for 25 years now in tipis, huts, sheds and now the underground room. 80 square feet.
Situated in a 2 acre meadow along the Wallowa River in eastern Oregon, my underground home is barely visible in the natural landscape.
A hobbit hole style home in Joseph, Oregon on land leased for $100/year. Owned and shared by Dan Price. More info. here.
