A duplex on Manhattan’s “Billionaires’ Row” and the former home of Eliot Spitzer were among the most expensive pads sold in the city this year.
Topping the list was a $91.5 million sky-high palace in Midtown on a stretch of West 57th Street known for its luxury high-rise buildings.
Bought by hedge-fund big Bill Ackman, the apartment on the 75th and 76th stories of the One57 tower was the second-costliest home ever sold in the city.
The record holder is still a 10,923-square-foot duplex penthouse in the same building that sold last December for $100.47 million.
The second-highest price for a home sold in Manhattan this year set a record for a co-op. The seller of the 14-room duplex at 834 Fifth Ave. was Jets owner Woody Johnson, who sold it for $77.5 million to Ukrainian-born billionaire Leonard Blavatnik.
A borough-by-borough analysis for The Post by real-estate Web site StreetEasy found that ex-Gov. Spitzer’s childhood home was the priciest sold in The Bronx this year. The compound at 4680 Livingston Ave. in Fieldstone went for $2.9 million.
In Brooklyn, fashion photographer Jay Maisel plunked down $15.5 million — the most ever paid for a home in the borough — for a house at 177 Pacific St.
The previous record holder was the Brooklyn Heights mansion at 70 Willow St. where Truman Capote once lived. It sold for $12.5 million in March 2012.
Brooklyn’s second-most-expensive home sale of the year was a $12.4 million pad at 17 Prospect Park West, the former residence of married actors Jennifer Connelly and Paul Bettany.
While the gap between the top prices in Manhattan and Brooklyn was huge, experts said it was not surprising.
“Brooklyn pricing keeps escalating, but for the 1 percenters, the cachet of being on the island of Manhattan commands a significant premium. It always has and always will,’’ said Leonard Steinberg, president of the Compass real-estate agency.
Still, the median price for Manhattan’s luxury homes — the top 20 percent of the market — was down more than 2.2 percent from October 2014 to October 2015, which were the most complete figures available, StreetEasy said.
Ackman, the buyer of the One57 duplex, had claimed he bought it “for fun,” but has since said that it was an investment and that he never plans to live there.
The unit, called the “Winter Garden” duplex, is 13,554 square feet and has six bedrooms.
Pricey home sales fell into expected neighborhoods, according to StreetEasy data analyst Alan Lightfeldt.
“For the most part, this year’s most expensive sales are clustered on the East Side and in Midtown, which aligns with what we traditionally expect from these areas of the city,” he said.
