One57

One57, formerly known as Carnegie 57, is a 75-story, supertall skyscraper at 157 West 57th Street between Sixth and Seventh Avenues in the Midtown neighborhood of Manhattan, New York City. The building has 92 condominium units above a 210-room Park Hyatt Hotel that serves as the flagship Hyatt property. The tower was developed by Extell Development Company and designed by Christian de Portzamparc. It is the first ultra-luxury condominium tower along a stretch of 57th Street called Billionaires' Row. One57 contains a facade made of panels in various shades of blue. The building has a curved roof and, on the side facing 57th Street, contains several setbacks that resemble waterfalls. One57's structural features include concrete floor slabs and two basement levels. The residential interiors contain furniture and materials by Thomas Juul-Hansen. On completion, the tower's design, particularly its facade and shape, was criticized. Extell CEO Gary Barnett started acquiring One57's site in 1998, although building plans were not filed until 2009. Construction started in 2010, and work reached the top floor by mid-2012. Toward the end of construction, there were two major incidents: a collapsed construction crane requiring the evacuation of nearby buildings, as well as a fire.…

Toward the end of construction, there were two major incidents: a collapsed construction crane requiring the evacuation of nearby buildings, as well as a fire. Upon completion in 2014, it was the tallest residential building in the city for a few months until the completion of 432 Park Avenue. The building set the records for the city's most and second-most expensive residences, selling respectively for $100.5 million and $91.5 million. However, sale prices started dropping in the late 2010s due to a general decline in the city's luxury condominium market. ==Architecture== visible at far left|alt=The base of One57 as seen from Seventh Avenue]] One57 was developed by Extell Development Company, which in turn was led by Gary Barnett. The building was designed by architect Christian de Portzamparc, while Goldstein, Hill & West Architects worked on the design details. The building has a roof height of and its top floor at . The certificate of occupancy issued by the New York City Department of Buildings lists the building as having 73 stories above ground level, with a height of . The top story is numbered as floor 90. 's works, cf. The Kiss|alt=Southern facade as seen from West 57th Street with setbacks resembling a waterfall, and western facade with tall windows in random shades of blue, gray, or simply black, reminiscent of Gustav Klimt's paintings with similar colors and patterns, such as The Kiss]]At ground level, One57 has an L-shaped floor plan extending both north to 58th Street and east along 57th Street. The building's massing, or shape, consists of varying curved and linear shapes. There are curved setbacks on 57th Street. The base of the building has undulating vertical glass strips around and above the entrances, which are also meant to symbolize a waterfall. The tower has rippled canopies and numerous setbacks on the 57th Street side. By contrast, the facade along 58th Street, facing Central Park, has a flatter profile without setbacks. A separate residential entrance also exists on the north facade at 58th Street. The facade uses various pieces of dark and light blue glass, mixed with pewter- and silver-colored glass. These glass panes were arranged to create vertical stripes and were intended to absorb sunlight in various ways and maximize views. De Portzamparc likened the glass patterning on the northern and southern facades to the work of Austrian painter Gustav Klimt, citing the artist's work as having inspired the design. According to facade contractor Permasteelisa, the facade is made of 8,200 pieces in over 2,200 distinct shapes, covering . A slightly different figure of 8,400 figures is cited by television network PBS. Among the shapes that are used in the facade are curved panels, at the setbacks; curved corner panels, at the extreme ends of the setbacks; "peel-outs", consisting of adjacent curved and flat panels; and the undulating "teardrop" panels around the entrances. Most shapes are used infrequently, with the most common shape being used about 300 times. The pinnacle was designed by Goldstein, Hill & West. The curved roof of the building conceals a cooling tower and tapers in width to . A window cleaning rig, measuring long and weighing , was constructed for the building. The window cleaning deck hangs from a retractable crane arm that is installed on the roof. ===Interior=== The interiors of One57 were made of material from around the world. Roy Kim, the senior vice president of design at Extell, traveled to Carrara in Italy to approve every piece of white marble used for the apartments' bathrooms, and he also traveled to China, Turkey, and South Korea to obtain materials. Some of the stone came from China; at one point, Kim reportedly asked one Chinese stone supplier to lay out all the stone on the ground of a warehouse so he could examine whether the stone could be used in One57. The marble collectively cost several million dollars; a single slab costing $130,000 was enough to create two benches and two bathtubs. The wooden furniture was from the English county of Wiltshire, where a company was contracted to hand-make 3,500 wooden cabinet doors as well as 135 kitchens in 18 layouts. The building is accessed via a lobby with lacquered woods. The lobby contains of steel panels, which collectively cost $800,000; they had to be carried into the building through a narrow gap without being damaged. ==History== ==Impact== ==See also== List of tallest buildings in New York City List of tallest buildings in the United States List of tallest residential buildings Sliver building ==References== ===Notes=== ===Citations=== ===Sources=== ==External links== One57 listing on skyscrapercenter.com
