http://www.tumbleweedhouses.com/houses/fencl/Well it's not exactly self sufficient but I have become quite enamored with these little mobile-homes, and believe they have a lot of potential (for a single person). Considering building one myself, I'm a firm believer in minimalism and as far as I'm concerned a 130 square foot house in western society is just about as minimalistic as you can get. Plus I would have the added freedom of being able to take my home and move whenever a please (which I do A LOT)
anyways thought some of you might be interested in them.
