New York's real estate market is soaring — and there's no better proof than the glitzy One57.
The 73-floor supertall skyscraper in midtown Manhattan has been crowned the new most expensive building in New York City as of 2015, according to a report by CityRealty.
The building's average price per square foot for the year was $6,010, while last year's most expensive, 15 Central Park West, came in at only $5,726.
One57's average price increased 18.5% from last year, while 15 CPW's average decreased 10%.
One of the penthouses in the 1,004-foot-tall residence closed this year for $100.5 million, making it the most expensive apartment ever sold in NYC, as well as the first to surpass $100 million.
Residents will have access to the amenities in the Park Hyatt hotel, which takes up the first 39 floors of the building. But if they don't want to mix with hotel guests, One57 owners can also use their own 20,000-square-foot amenities floor, complete with a pool, gym, library, and theater.

One57 was designed by starchitect Christian de Portzamparc to look like a cascading waterfall. It rises 1,004 feet and 90 stories above 57th Street.
Of the units sold so far, only some of the buyers are known. They include billionaires Lawrence S. Stroll and Silas K. F. Chou, as well as the head of BDO Unicon Group, Andrey Dubinsky.
The Park Hyatt hotel will occupy the first 39 floors of the building, and the 95 condos of One57 will fill the rest of the space.
