The Lower East Side apartments for sale at One Manhattan Square are flying off the market. Rising 80 stories above the Downtown Manhattan waterfront, the Extell-developed tower has outpaced sales at any other building in New York, with an average of 12 sales per month over the last three months, according to a new analysis from Marketproof—and it’s not hard to see why. In addition to stunning interior design in each home, the building’s residents can enjoy more than 100,000 square feet of amenities, including the city’s largest private garden, a 75-foot-long indoor saltwater pool, a two-lane bowling alley, squash and basketball courts, and alfresco dining and grilling areas, among many other perks.
