The design concept is based on the nearly square perimeter of the apartment. A black cube is placed, floating, in the open floor plan, creating living space within and around the black volume. Additional volumes – the black granite kitchen island – continue to define an open living space on the north side of the loft. The design was influenced by the owners’ art collection and library. The black cubic volume accommodates both the library and vertical surfaces for larger art works in the collection. photographs by Amy Barkow.
