Loft apartments have naturally good bones for dramatic living spaces, with those big windows and high ceilings, but the renovation of this 1,300-square-foot Williamsburg pad truly resulted in some breathtaking spaces. The work is by Greenpoint-based design and architecture firm Space Exploration and general contractor Tristan Warner Studios Inc. According to Brownstoner, Space Exploration was initially hired to create a wall-length book shelf for the living room, where the ceiling surpasses 18 feet. The success of the bookshelf — which was built by a high-end millwork firm in Brooklyn — inspired the owner to “go forward with the full monte,” said founder of Space Exploration Kevin Greenberg. His full reno enlarged the lofty mezzanine space, while decked out the interior with truly unique custom design touches.
