432 Park Avenue is a supertall residential skyscraper in Midtown Manhattan, New York City. Originally proposed to be 1,300 feet (396 meters) in 2011,[4] the structure topped out at 1,396 ft (426 m).[3][5][6] It was developed by CIM Group and features 104 condominium apartments. Construction began in 2012 and was completed on December 23, 2015.[1]

The building required the demolition of the 495-room Drake Hotel. Built in 1926, it was purchased for $440 million in 2006 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,[7] 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.[8] 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 tallest building in the world known only by its street address, replacing Chicago's 311 South Wacker Drive.

Height

432 Park Avenue is the second-tallest building in New York City and is the tallest residential building in the western hemisphere.[9] By mid-2018, 217 West 57th Street and 111 West 57th Street will be at a similar height.[10] The tower has a footprint of approximately 33,000 square feet (3,100 m2).[11] The building was officially topped out on October 10, 2014,[5][12] making it the highest rooftop in the city.

Design

Designed by architect Rafael Viñoly around what is described as "the purest geometric form: the square" and inspired by a trash can designed by Josef Hoffmann,[13] 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.[14]

Fashion consultant Tim Gunn described the building as "just a thin column. It needs a little cap."[15]

Apartments and amenities

The tower's condominium units feature high ceilings, and will range from a 351-square-foot (32.6 m2) studio to a six-bedroom, seven-bath penthouse with a library, already under agreement for $95 million. [9][16] The building's amenities will include 12-foot (3.7 m) golf training facilities and private dining and screening rooms.[17]

The first sale of apartment #35B, was reported in January 2016 for $18.116 million, over the $17.75 Million asking price. 10 additional apartments were available at the time ranging from $17.4 to $44.25 million. #35b covers 4000 sq. ft., one half of the 35th floor of the tower, and contains 3 bedrooms and 4 1/2 baths. Each face has six 10 ft. by 10 ft. windows, which for #35B, face south and west with views of Central Park.[18][19]

Engineering

The structure of the tower is composed of a 30 ft. square reinforced concrete core with 30 in. thick walls, that 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. wide columns and equal width spandrel beams of reinforced concrete that encloses the symmetrical "basket grid" of window openings. The columns begin at a depth of 5 ft. 4 in. at the bottom of the tower, to as little as 20 in. at the top. This layout permits all of the interior space on each floor to remain fully open for the complete 27 foot span between the core and shell.[20][21]

The facade, 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 88 stories is 15 ft. 6 in. with 10 in. thick floor slabs, although to dampen the acceleration from wind loads, upper floors have slabs up to 18 in. 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 floor 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. [21]
