Soaring 1,396 feet above Manhattan’s famed Park Avenue, between 56th and 57th Street, 432 Park Avenue is not only the tallest residential building in New York City but also the tallest residential tower in the Western Hemisphere.Designed by world-renowned architect Rafael Viñoly and co-developed by Macklowe Properties and CIM Group, 432 Park Avenue comprises 106 luxurious residences each considered the most sought after addresses in the City.Rafael Viñoly Architects’ unique new residential and mixed-use tower rises to become a prominent feature of the New York City skyline from its site at the intersection of Park Avenue and East 57th Street. The building is a slender, unencumbered volume that marks the geometric centre of the skyline. The project consists of residences on middle and upper levels and common spaces distributed throughout the lowest levels. Two smaller volumes adjacent to the tower house retail and commercial office spaces facing onto East 57th Street.432 Park is an expression of the extraordinary qualities of the Manhattan grid and its design exploits these parameters. A regular grid of exposed concrete members creates an open basket within which seven independent buildings stack up, separated by spaces within which the building cores are exposed to the outdoor elements. These breaks allow for deflection of wind pressures and help the 1,396-foot (425-meter) -tall building, with its 1:15 slenderness ratio, achieve structural stability. The six upper volumes, starting 200 feet (61 meters) above grade, contain 53 residential floors housing 106 units with panoramic views. The floor plan, with 12.5-foot-tall (3.8-meter-tall) ceiling heights and rooms that are unencumbered by structural elements, also provides flexibility for custom redesigns of the units. Each floor measures approximately 8,740-square-feet (812-square-meters) and can accommodate from one to three residential units.The lowest section of the tower is totally devoted to the amenities provided exclusively for the residents: staff accommodations, conference facilities such as a meeting room and a screening room, a fully-equipped restaurant opening to a garden terrace overlooking 57th Street, health and spa facilities including a fitness center and swimming pool, independent storage spaces, wine cellars, and a sub-grade parking garage. At the base, the building meets the ground creating a landscaped public space that extends the feeling of openness of Park Avenue onto 56th Street. A private porte-cochere defines the entrance to a discreet residential lobby. All services and delivery accesses are independently located to the east side of the tower. On 57th Street, a retail volume maintains its own functional and architectural identity while simultaneously aligning with the geometric discipline of the tower above. This object extends the exclusive character of the retail experience of Madison over to Park Avenue. On Park Avenue, a freestanding fully glazed retail cube marks the access to the site.Slender, tall, residential and mixed-use tower rises as a prominent feature of the New York City skyline design based on the geometry of a square stacks seven independent buildings on top of each other to create one of the city’s tallest structures Public plaza and retail volume at tower base maintain their own identities while referencing the geometry above.
