Feeling cramped in your home? Then you're not likely ready to live on 100 square feet. Tumbleweed Tiny House Company builds housing that is small enough to haul behind most pick-up trucks. The layout here shows a 100 s.f. home. These homes come complete with electricity and running water (which can be connected from a standard outlet and garden hose respectively). Also, since these buildings can be hauled they apparently don't have to pay property tax! NPR has more pictures and details about these tiny homes.
*PS* You might have noticed the "Hopper" feature on the right. It's brand new! It should show the last five things I've decided to broadcast from my Google Reader feeds.
