businessinsider.com – Before small living became ubiquitous, one Chinese architect had already designed a transforming micro-home.

Gary Chang, 54, has designed projects all over the world, but he’s perhaps best known for his own 344-square-foot Hong Kong apartment. The sunny dwelling seems like an ordinary studio apartment until Chang starts pulling walls and furniture around to create over 24 different rooms, from a kitchen to a so-called gaming room.

The founder and managing director of Edge Design Institute, Chang became a global phenomenon when he was interviewed by The New York Times back in 2009 about his incredible space.
