YMFY dug up this video of Hong Kong resident and architect Gary Chang who devised a way to turn his tiny flat into a full-fledged house. Hong Kong apartments are known to be quite small and Gary used a series of sliding walls to conceal different room configurations. With a pull of a handle here and there, Gary can transform his bedroom into a kitchen, a living room, or even a bathroom.

It’s hard to get a grasp of just how remarkable his apartment is, so I suggest watching the video below from a segment on World’s Greenest Homes.
