This nine room prewar duplex maisonette, in a prime full service Park Avenue co-op, provides an exciting design opportunity. With enormous potential for a grand space with pretty leafy views facing Park Avenue, there is an entrance directly from Park Avenue as well as from the building. Four bedrooms can be created, and 4-5 baths, as the floorplan is flexible. The living room with wood-burning fireplace is adjacent to a formal dining room and library. An eat-in kitchen with adjacent staff room and bath are additional possibilities. There are hardwood floors and high ceilings with west and north exposures. Excellent bones=huge potential! The apartment has been measured to have approximately 2,700 square feet.
