Hong Kong architect Gary Chang has renovated his tiny apartment four times since he's owned it. The most recent renovation is called "The Domestic Transformer".
The wall units, which are suspended from steel tracks bolted into the ceiling, seem to float an inch above the reflective black granite floor. As they are shifted around, the apartment becomes all manner of spaces -- kitchen, library, laundry room, dressing room, a lounge with a hammock, an enclosed dining area and a wet bar.
Chang's Suitcase House uses many of the same principles as his apartment.
