A waterfront West Village condominium still under construction just changed the game for downtown Manhattan.

An unknown buyer is in contract to purchase multiple apartments at the 80 Clarkson development for $129 million. The record-breaking deal was first reported by the Real Deal.

Sources told the outlet that Michael Balanevsky, a broker at Accent Holdings, brought in the mystery buyer. The outlet cited Balanevsky’s website, which boasts deals in New York City and the Hamptons, and a “strong Russian clientele.”

If the 80 Clarkson contract goes through, the sale will easily take the crown for the priciest pad in ever sold downtown — and the fifth most expensive home in Manhattan history.

The notoriously pricey city has seen only a handful on nine-figure deals. The leading four are concentrated in just two buildings — 220 Central Park South and Aman New York — both located well above 14th Street.

Ken Griffin’s roughly $238 million deal at 220 Central Park South has comfortably held the city record since 2019 — not to mention that for the most expensive home ever sold in the US. The other three top-ranked sales ranged between $135 million and $188 million.

The potential entry of the $129 million 80 Clarkson deal into fifth place is a true high-water mark for the downtown luxury sales market.

The ultra-luxury 80 Clarkson, designed by COOKFOX Architects, is among the hottest in Downtown Manhattan. The under-construction complex will consist of two towers rising 420 and 490 feet along the Hudson River and the West Side Highway. The complex’s 112 units will be accessed by a private, gated entrance and motor court.

The buzzy project is developed by Zeckendorf Development and Atlas Capital Group, with the Baupost Group. When completed, 80 Clarkson will be the tallest building in the West Village.

The developers’ in-house sales team, led by Dan Tubb and Amy Williamson, quietly launched sales earlier this year — and what a year they’ve had.

The Post reported in October that 80 Clarkson had racked up nearly $1 billion in whisper-listing sales. Its most expensive individual unit, a more than 7,000-square-foot duplex penthouse, was earmarked at $80 million, according to filings with the New York Attorney General’s Office. The developers reported anticipated sales well north of $2 billion.

Increasingly, condos are king in downtown Manhattan, even in tony townhouse enclaves like the West Village.

Out-of-town money and wealthy young moguls are looking away from prestigious uptown addresses in favor of downtown cool — but they still want the white-glove experience. Developers are eagerly meeting those demands.

Frankenmansions and luxury condos are all the rage in the villages. An upcoming boutique condominium in Greenwich Village, once a parking garage, recently priced its penthouse at $85 million. A duplex in the new condo tower at 140 Jane St. — another from Aurora Capital — is currently in contract for $87.5 million.

If Balanevsky’s 80 Clarkson buyer stays the course, they’ll blow that record out of the water.

A spokesperson for the developers declined to comment. Balanevsky, Tubb and Williamson did not respond to requests for comment.
