Innovative architects turn used shipping containers into homes

In this era of scouring the earth for the magic bullet in home building, few ideas can compete with the weird, pragmatic beauty of the used shipping container. Cheap, strong and easily transportable by boat, truck or train, these big steel structures now litter the ports of America as mementos of our Asian-trade imbalance. (Many more full containers arrive on our shores than depart, so ports either ship them back empty -- to the tune of about $900 per -- or sell them.)
