A penthouse flat in Brooklyn, New York, could be sold for US$20 million – and if the deal is finalised, it will be on track to shatter the record for the most expensive home ever sold in the borough.

According to The Wall Street Journal, the current record is held by a Cobble Hill town house that was bought for US$15.5 million in 2015.

Located in Quay Tower, the penthouse is actually two units that are being combined into a single flat, the property blog Curbed New York reports.

Andrew Anderson, of Douglas Elliman Development Marketing, which is handling sales at Quay Tower, said: “No other property in Brooklyn or New York City has this combination of ultra-high-end interiors and amenities paired with absolutely mesmerising views of New York Harbour, the [central] Downtown skyline and East River all the way beyond the Empire State Building.”

Let’s take a closer look at the luxurious apartment.

The penthouse is at the top of the 30-storey Quay Tower and is one of 126 units in the building.

The apartment is located in Brooklyn Heights and offers views of both the Hudson and East rivers. Its location, added Anderson, “makes it all the more precious”.

The penthouse features floor-to-ceiling windows, from which the Manhattan skyline, Brooklyn Bridge Park, and the Statue of Liberty are all visible.
