Offered for sale for the first time in 40 years, this iconic penthouse apartment occupies the South/East tower of the Beresford, one of the most recognizable and sought-after buildings on Central Park West. It offers dramatic 360-degree views of Central Park, the southern skyline, and the Hudson River, and one of the largest terraces on Central Park West. A private windowed Elevator Foyer on the main floor of the apartment opens to a Gallery with a curved staircase connecting the upper three floors of the quadraplex. There is a large, well-proportioned Living Room with 10.5' ceilings, a fireplace, and wide sliding glass doors opening to a wraparound balcony overlooking the American Museum of Natural History and the park. The adjoining Library has an en-suite bathroom, and could be used as a second Bedroom. An elegant, oversized formal Dining Room affords beautiful South views, and connects to a spacious Kitchen. A back stair leads to two Staff Rooms with a full bathroom on the lower level. The 3rd floor of the penthouse accommodates a large Master Bedroom Suite with a separate Dressing Room and bathroom, and an expansive 52 ft. x 44 ft. Terrace overlooking Central Park. The top floor of the apartment is occupied by a spectacular Great Room with 17' high ceilings, a fireplace, and breathtaking views from double height windows to the East, North and West. The Penthouse has been called a "crown jewel of the Manhattan real estate market", and the architectural critic Paul Goldberger described the apartment as "extraordinary; it is the apex, the architectural climax of the building".
