Green Life in a Tiny House

Dee Williams wanted a simpler, greener life - so she built her dream house, an 84-square-foot cottage on wheels, which is currently parked in a friend's backyard. Not only did she save money using salvaged materials (the front door came from a dumpster, for instance), but the entire house is small enough to fit into a standard parking spot. Says Williams, 'Right now, there's nowhere else I want to be.'

Williams’ trailer cottage is surprisingly roomy inside, largely thanks to its clever use of height. For example, Williams’ bed is in a loft above her kitchen.

Williams is proud to have fulfilled her goal of minimizing her ecological footprint. Her monthly heating bill is $6 and, thanks to solar panels, her electricity is free. Her approach goes against the national trend: Americans consume 40 percent of the world’s oil and 23 percent of its coal.
