One57, formerly known as Carnegie 57, is a 75-story, 1,005 ft (306 m) supertall skyscraper at 157 West 57th Street between Sixth and Seventh Avenues in the Midtown neighborhood of Manhattan in New York City.

However, sale prices started dropping in the late 2010s due to a general decline in the luxury condominium market in New York City.

[17] The dark and light glass on the building's exterior was intended to create vertical stripes, absorb sunlight in various ways, and maximizes views.

[20][21] The eastern and western facades are designed with a color effect that de Portzamparc described as being similar to the work of Gustav Klimt, the Austrian painter.

Structurally, the superstructure is made of concrete flat plates, with floor slabs between 10 and 12 in (250 and 300 mm) thick and columns up to 30.5 ft (9.3 m) apart at their centers.

In addition, there are three mechanical levels spread out across the building, surrounded by one-story concrete walls, which in turn are designed to resist lateral forces.

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.

[40][44] The spa's name was derived from the word for "serenity" in the Munsee language, originally spoken by the Lenape Native American population of Manhattan.

[44][37] The hotel also originally included an American grill called the Back Room, which was led by chef Sebastien Archambault when it opened in August 2014.

[16] Typical of the full-story units is the apartment on the 62nd story (labeled as floor 82), designed with a 56 ft-wide (17 m) salon overlooking Central Park, as well as a breakfast room, kitchen, private foyer, reception gallery, and 12 ft (3.7 m) ceilings.

[53][54] The apartments were furnished with Italian marble, rosewood flooring, specialized lighting and hardware, and kitchen appliances made by Smallbone of Devizes.

Among the features of that unit were marble-slab floors, white-gold leaf walls, a white-oak paneled living room, and a vaulted dining-room ceiling.

[5][32] A New York Times reporter, writing on the amenities in 2018, wrote that the building's "lifestyle attaché" Sascha Torres had also created events such as a wine-tasting, jazz concert, and Halloween trick-or-treating for the residents.

The bins were marketed for up to $200,000 in 2011, which at the time was a higher price per square foot than most Manhattan apartments and, according to The Wall Street Journal, more than a single-family home in Topeka, Kansas.

[72] The following month, the media reported that the website of project contractor Aegis Security Design indicated that the site would include a Park Hyatt hotel, along with stores and luxury condominiums.

At the time, Extell was consulting with city agencies to purchase air rights from neighboring sites, including the Alwyn Court and 165 West 57th Street.

[5][32] At the end of that month, Sotheby's International Realty broker Elizabeth Sample said that many millionaires and billionaires had expressed interest in the building's sales showroom.

[96] On October 29, 2012, in the aftermath of Hurricane Sandy, the construction crane on the building partially collapsed,[97] requiring a six-day evacuation for thousands of neighborhood residents.

[102] However, the crane was inspected a week earlier and considered in good shape, leading city officials to call the boom's failure a freakish occurrence.

[126] Media outlets reported in 2016 that the International Petroleum Investment Company—the parent company of the building's main financier, Aabar—was linked to the 1Malaysia Development Berhad scandal.

[132] Amid a downturn in New York City's luxury real estate market, Extell unveiled new buyers' incentives in 2018, offering to waive between three and five years of common charges and pay 50% of broker's commissions.

[136] One unit sold in January 2021 for half its original listing price,[137] and The Wall Street Journal reported the same June that some owners had seen "percentage losses in the double digits" during the past couple of years.

[144] The building set the record for the city's second-most expensive residence in 2015, when hedge fund manager Bill Ackman bought a 75th floor duplex for $91.5 million.

[151] The youngest buyer on record was a two-year-old Chinese girl, whose mother paid $6.5 million for a unit in 2013 so her daughter could use it when she attended college in fifteen years.

Candy had wanted to resell his apartment immediately after he had renovated it, while the anonymous buyer was unwilling to cooperate with Extell to minimize disruption for neighboring units.

"[155] According to New York magazine's architecture critic Justin Davidson, One57 was "so clumsily gaudy that a fellow architect surmised [that de Portzamparc] must be a socialist pranking the plutocrats".

[157] Another architecture critic, James Russell, characterized the facade as "endless acres of cheap-looking frameless glass in cartoonish stripes and blotches of silver and pewter".

[158] Michael Kimmelman, in The New York Times, contrasted One57's "pox of tinted panes" against de Portzamparc's earlier, "jewel-like" LVMH Tower nearby.

[160] Of One57's presence in general, Rick Hampson of USA Today wrote: "One57 exemplifies a new type of skyscraper—very tall, improbably slender, ostentatiously opulent—that is reshaping a famous skyline composed mostly of bulky office buildings.

[161] Elizabeth Goldstein, the president of the Municipal Art Society, said the construction of One57 had precipitated the development of other supertall skyscrapers in New York City, many of which used zoning loopholes to rise higher than would normally be allowed.
