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 on top of a new Park Hyatt Hotel with 210 rooms, the flagship Hyatt property. The tower was developed by Extell Development Company and designed by Christian de Portzamparc. It was 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. The tower's design, particularly its facade and shape, was negatively critiqued upon its completion. 

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. 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 luxury condominium market in New York City.
