Hey you, do you like Lord of the Rings? Even if you don't (shame on you), you gotta admit, this is pretty cool.
The guy who built this house is named Simon Dale. He built it in four months for £3000 (about $4750) for himself, his wife, and his two kids to live in. It's dug into the ground, meaning that it's insulated from the weather, and was constructed wholly from materials found on his property in Wales. You don't have to be a green freak to want one of these houses. Check out the crazy awesome ceiling.
And he doesn't even do architecture. To see more pictures and learn more about how you can build a hobbit house of your own, check out his site: http://www.simondale.net/house/index.htm. There's forums, a how-to guide, and other useful resources. I know what I'm doing this summer.
