New York architecture studio HWKN (Matthias Hollwich and Marc Kushner) has a new shelving system called the Wall Unitizer that looks kind of like a cupboard virus has sprouted and spread through your apartment. It's a bit of an Archigram-style take on turning the home into an extension of the body. The walls are everything you need: shelves, seating, desk space. Plus, if you live in a typical coffin-sized city apartment, everything's within arm's reach!
So far they've only done one, for some lucky client on the U.E.S. It was heavily customized, down to optimal chair and desk height, but I hope they think of mass producing this thing. More info on the shelves and the studio here.
