New York real estate web site The Real Deal has reported that a buyer is considering paying US$250 million ($325.5 million) to have two units in the 220 Central Park South Building combined into one luxury penthouse.
If the sale goes ahead, it would set New York, American and world records for the price paid for a unit.
The current record price for a New York apartment was set at US$100.5 million in January, while the most expensive units on the market across the United States are asking for US$195 million.
A US$250 million sale price would also see it pass the current world record US$237 million paid in 2014 for a Hyde Park One unit in London.

Developer Vornado expects total sales for the project will eclipse US$2.8 billion.
