This is NYC’s priciest home for sale — and it’s located in the world’s skinniest tower

The Big Apple just got bigger — at least when it comes to the price of this newly listed “quadplex” penthouse.

On Thursday, according to StreetEasy, this four-level nest listed at 111 W. 57th St. on Manhattan’s Billionaires’ Row — the building itself being the skinniest skyscraper on the planet and the second-tallest residential building in the United States.

Listed for $110 million, moreover, the grand unit is now the priciest for sale in New York City, StreetEasy additionally shows. 

Every unit in 111 W. 57th St., also known as Steinway Tower, takes up at least one full floor, but Penthouse 80 at the tippy top takes up those four. 

The dwelling spans 11,480 square feet over the 80th to 83rd floors, with 618 square feet of exterior terraces. 

The lofty residence, the listing of which was first reported by Bloomberg, boasts floor-to-ceiling windows and 14-foot ceilings. It currently includes five bedrooms and six full bathrooms.

The vacant condo’s suggested floor plan was designed by Studio Sofield, but the $110 million asking price includes a full buildout and redesign, if an ultra-wealthy buyer so chooses.

Currently, the first floor — on the building’s 80th story — includes a grand entry hall and a south-facing kitchen with access to an outdoor terrace.

Four bedrooms take up the second floor, each with an ensuite bathroom, as well a lounge area and a wet bar. 

The third floor is taken up by a 2,800-square-foot primary suite, which boasts two ensuite bathrooms — one clad in gray onyx and the other in white onyx. The final and fourth floor, the “crown suite,” was made for lavish parties, with a bar, a private screening room, a service kitchen and an outdoor terrace.

A quadplex in Manhattan is rare indeed. Hedge fund billionaire Ken Griffin famously snagged one in 2019 at nearby 220 Central Park South for roughly $238 million, making it the most expensive home ever sold in the US. That record remains to this day.

Lead listing broker Nikki Field of Sotheby’s International Realty told Bloomberg that the Steinway Tower quadplex was originally two duplexes, but the decision was made to up the ante by combining them.

Previously, nearby Central Park Tower was home to the city’s most expensive residences. One, a penthouse that listed for a breathtaking $250 million in 2022, later had its price reduced to $195 million. The other, called “Sky House,” asked $150 million when it listed in 2024.

Today, neither of them remain for sale, we hear. The former, according to StreetEasy, left the market in October 2024. The latter, the listings portal also shows, was taken off the market in March. (Extell, the developer behind Central Park Tower, didn’t respond to a request for comment.)

Steinway Tower has seen a spate of contract signings in recent months. Nikki Field’s team at Sotheby’s, which took over sales at the tower in the summer of 2024, takes the credit. The team made management and staffing changes to the building, Bloomberg reported.

Field’s efforts seem fruitful. The firm reported $187 million in deals currently under contract, with eight contracts so far this year. That includes Penthouse 72, which last listed for $56 million. Steinway Tower has 80 units — 75% of which are now sold. Field did not respond to The Post’s requests for comment.

This is all welcome news for the skyscraper, which opened its doors in 2022 after a fraught construction process. Initial sales were sluggish and prices were reduced, even into last year.

Field told Bloomberg that Penthouse 80 was held back until sales proved strong enough to support the listing. It appears that the time was finally right — market reports and in-the-know brokers confirm that ultra-luxury sales in Manhattan are booming this year while supply remains low.
