Teeny Tiny Houses
Lots of links for teeny tiny houses. This first one is to a video of a news story (probably about 15 minutes long) all about small (and usually inexpensive) houses including the owner of Tumbleweed Tiny House Company's less than 100 square foot, year round home, and a yurt.
Another short article. No photos.
Pictures and specs of Tumbleweed Tiny Houses.
He also has a book of house plans for sale and the house plans themselves. Homes can be built following his plans or he will make one for you. He says it usually takes about 8 weeks and then you can come pick it up (the homes can be built on wheels so I guess you just hook it up and drive off). There a pictures and descriptions of a number of different sizes and designs and prices. I was impressed that he would actually show prices instead of making you ask for them(that "If you have to ask, you can't afford it " mentality). Interesting website definitely worth a look.
I'd have to get rid of so much stuff but I'd love to try this. He says his utility bill is about $3 per month (at least I think that's what he said). I could live with that.
