Small, apparently, is in. That would explain the phenomenal popularity of the Mini Cooper, the space-conscious offerings at Ikea and Mp3 players that are easier to lose track of than a pair of earrings. So it was only a matter of time before small became cool in the housing market, too. How small can you get? Try the 77-square-foot Micro-Compact Home on for size. It may be smaller than some SUVs, but it ingeniously fits the living amenities you'd find in most tiny Japanese apartments, state-of-the-art sound system and flatscreen TV included.
