How's this for an ingenious method of turning a teeny weeny single room flat in Hong Kong into a 24 "room" flat with the aid of a couple of rails, wheels and shelving units...

This is a brilliant use of the space you've got, but lets just hope developers in London don't cotton onto this idea any time soon. They'll be charging a bomb for a modern 24-room apartment at the blink of an eye. Actually, come to think of it, I'm surprised IKEA don't already sell this concept flat-packed.
