This is a new cool module design for residences in Belgium. It maximizes space while minimizing space at the same time. Put it this way, it's only 7'10" wide, but stacks the four integral rooms necessary for living: Entrance, Dining, Living, Sleeping and a rooftop bathtub. Love the different colored lighting for each floor. If NYC used these residences, there'd be so much more living space and equalitarian rent. Wishful thinking.
