The Tiny Premade House
Heads up: tiny houses are currently available at Costco, where they start at around $4K for a furniture- and appliance-free shell. More information is available at Home Place Structures, although the appealing “Chalet Garden Building” page seems to be broken. (All of this via the glorious Tiny House Blog, collector of all things tiny house, whose recent highlights include an exploration of the sinktoilet and a tour of the adorable Fortune Cookie caravan.)
