It was just a partial renovation of a new Tribeca loft for a repeat client, but the transformation was dramatic. In place of a shabby kitchen cut off from the dining room, the new kitchen is sleek and open. A wall of tall storage screens the foyer, while providing a platform for the owners’ collection of ancient sculptures. Tucked behind a pocket door, the new laundry room is a serene backdrop. And the new guest bathroom is all chic minimalism.
