The 6,000-square-foot-unit, a combination of two apartments on the 35th floor in the westernmost “tower” portion of the dual-building limestone complex, has unobstructed views of Central Park and the Hudson River, Del Nunzio said.

It’s the largest available home at 15 Central Park West, where original buyers in 2007 and 2008 saw the value of their investments double on average in 2012, the year Weill and his wife sold their condo at twice their $43.7 million purchase price.

“This building is a micro-market all unto itself,” Del Nunzio said. “Other buildings are trying to compete, but this building is proven gold.”

Schecter’s asking price, at $10,833 per square foot, is less than the record-high $13,049 a square foot that Weill got for his apartment on a lower floor, according to Del Nunzio.

New York is No. 1 on a list of the world’s “cities that matter” to high-net-worth individuals, according to the 2013 “Wealth Report” by Knight Frank LLP, a London-based property consulting firm. The city’s real estate has come “to epitomize the so-called safe-haven market, with overseas buyers looking to escape currency, economic, political and security crises by putting equity into tangible assets.”

United Nations

Builders seeking to capitalize on that demand include Arthur and William Lie Zeckendorf, who are completing a 43-story condo tower across from the United Nations Secretariat headquarters in Midtown. Their firm, Zeckendorf Development Co., started marketing the units in October.

Prices range from $2.2 million for a 1,147-square foot one- bedroom unit to $100 million for a 15,597-square-foot triplex penthouse that includes an infinity pool, 14 bedrooms and a 10,000-pound stainless-steel staircase connecting each floor.

The Zeckendorfs, who also developed 15 Central Park West, decided to combine two units to create the penthouse after they gauged strong demand for larger properties.
