The apartment's late-seventies-luxury interior architecture was done by Lobel's close friend Greg Sharp, who was responsible for the white-granite floors, track lighting, and the pièce de résistance: the massive wood-veneered central cylinder that houses Lobel's walk-in closet (it peeks out at the end of the hallway). In the entry way is a serigraph by James Rosenquist. The guest bathroom, right, features massive African slate tiles and a teak sink.
