This small apartment, designed by Spanish architect studio PKMN architectures, is all about space and movement. Here the occupants can create their own ideal interior, as open or private as they like, just by moving the walls and partitions. Clever mechanics and unified color scheme make these transitions look and feel seamless, as if the space takes different shapes on its own, morphing along with the movement of the people in it. Watch the video after the break to see the process in action.
