432 Park Avenue is a residential skyscraper in New York City that overlooks Central Park. Originally proposed to be 1,300 feet (396.2 meters) in 2011, the structure topped out at 1,396 ft (425.5 m). It was developed by CIM Group and features 125 condominium apartments. Construction began in 2012 and was completed on December 23, 2015.
The construction was preceded by the demolition of the historic 495-room Drake Hotel and adjacent, typical 19th-century New York townhouses. Built in 1926, the Drake was purchased for $440 million in 2006 (equivalent to $520 million in 2016) by developer Harry Macklowe and razed the next year. Its footprint became one of New York's most valuable development sites due to its location between East 56th and 57th Streets on the west side of Park Avenue.
As completed, 432 Park Avenue is the third-tallest building in the United States and the tallest residential building in the world. It is the second-tallest building in New York City, behind One World Trade Center, and ahead of the Empire State Building. It is also the first, and so far only, building in New York City outside the World Trade Center Complex to be taller than the original twin towers.
432 Park Avenue officially topped out on October 10, 2014, at 1,398 feet (426 m) making it the second-tallest building in New York City after One World Trade Center and the fifteenth-tallest building in the world. Because much of One World Trade Center's height is in its spire and its base is nearly 40 feet (12 m) lower, the rooftop of 432 Park Ave is, as of 2018 , the highest in the city.
The tower sits in the middle of the block bounded by East 56th Street, Madison Avenue, East 57th Street, and Park Avenue. The building's 100-foot (30 m) base covers most of the 41,000-square-foot (3,800 m2) lot. The tower is a 93-foot (28 m) square in plan, giving each floorplate an occupiable area of 8,255 square feet (766.9 m2). At 15:1, 432 Park has one of the greatest height-to-width ratios of any skyscraper in the world.
The design of the structure was conceived by architect Rafael Viñoly who was inspired by a trash can designed in 1905 by Austrian designer Josef Hoffmann. The tower has eighty-four 8,255-square-foot (766.9 m2) stories, each with six 100-square-foot (9.3 m2) windows per face. Interiors are designed by Deborah Berke and the firm Bentel & Bentel, which also designed Eleven Madison Park and the Gramercy Tavern. Berke's design brief was simply "no set budget, make it look fantastic". To support its thin orthogonal frame, the structure features larger columns at its base than on the upper floors.
The tower's condominium units feature high ceilings, and range from a 351-square-foot (32.6 m2) studio to a 8,255-square-foot (766.9 m2), six-bedroom, seven-bath penthouse with a library, which sold for $95 million to real estate mogul Fawaz Al Hokair. The building's amenities include 12-foot (3.7 m) ceilings, golf training facilities and private dining and screening rooms.
The first sale of apartment #35B was reported in January 2016 for $18.116 million, more than the $17.75 million asking price. Ten additional apartments were available at the time ranging from $17.4 to $44.25 million. #35B covers 4,000 square feet (370 m2), one half of the 35th floor of the tower, and contains three bedrooms and four-and-a-half baths. Each face has six 10 by 10 ft (3.0 by 3.0 m) windows, which for #35B, face south and west with views of Central Park.
The structure of the tower is composed of a 30-foot (9.1 m) square, reinforced concrete core with 30-inch-thick (76 cm) walls, which the engineer, Silvian Marcus, describes as "like the backbone of a body." This core houses the elevator shafts and all the building mechanical services. The outer structural skin is composed of a grid of 3 ft 8 in (1.12 m) wide columns and equal width spandrel (horizontal, exterior) beams of reinforced concrete that encloses the symmetric "basket grid" of window openings. The columns begin with a depth of 5 ft 4 in (1.63 m) at the bottom of the tower, to as little as 20 in (51 cm) at the top. This layout permits all of the interior space on each floor to remain fully open for the complete 27 feet (8.2 m) span between the core and shell.
The façade, with the formed surface left as the final finish without any added facia, was poured in place from concrete using 14,000 psi white Portland cement, and cast around preassembled full-floor cages of #20 rebars with articulated steel formwork. The floor-to-floor height of each of the 85 stories is 15 ft 6 in (4.72 m), with 10 in (25 cm) thick floor slabs, although to damp the acceleration from wind loads, upper floors have slabs up to 18 in (46 cm) thick to add more mass. Also aimed at reducing the potentially uncomfortable effects of swaying due to wind vortex loading on such a flexible tower, the window grid and interior space of 2 floors between every 12 occupied floors are left open to allow the wind to pass through. These floors also contain modularized mechanical services for the six floors above and below to reduce ductwork. In addition two tuned mass dampers are located at the top of the tower and in the outriggers of some of the mechanical floors to help damp the motion.
By the end of 2015, close to 90% of the apartments had been sold, with almost every other owner being a foreign citizen, "part of a global elite that collects residences like art." It has been estimated that the majority of the units will remain unoccupied for more than ten months a year.
