It might not be 24 different rooms, but it's still innovative small space living. For this Tokyo apartment, Japanese designer Yuko Shibata created separate living and working spaces by installing two mobile walls. Entitled Switch, the design features one partition that slides out over the dining table to create a meeting room on one side and library on the other.
The bookcase you see in the photo also pivots to transform into a bedroom.
