We like it when homeowners think outside the box. The owner of this renovated basement, which took gold in the Fun Room category in 2006, passed on putting in an ordinary theater. Instead, the room serves as disco, complete with a 106-inch drop-down screen, controllable strobe lights, 2,000 watts of head-banging audio power and a DJ booth packed with commercial-grade mixing equipment.
