The Flatiron Building has found a buyer for its most expensive listed condo. 

Spanning the entirety of the 21st floor in the historic building, Unit 21 was asking $58.5 million when it went into contract, according to StreetEasy. 

The home spans over 7,400 square feet and has five bedrooms and five full bathrooms. It has a tiny 33 square foot terrace at the northern tip of the triangularly-shaped building, according to the offering plan. The listing includes no description of the condo itself.

The home was originally priced at $50 million in the development’s offering plan filed with the Attorney General’s office last year.

The deal comes just days after the project scored another deal for a full-floor condo on the seventh floor, asking $30.5 million. That unit, which was originally designed to be two separate condos, will span 7,700 square feet and likely have seven bedrooms and seven bathrooms. 

The conversion project at 175 Fifth Avenue quietly launched sales in the fall. It has since put nine of its 38 apartments into contract. The project has yet to release pricing for its penthouse unit, which spans roughly 4,600 square feet and will have 6,500 square feet of outdoor space. 

Amenities at the redeveloped property at 175 Fifth Avenue include a gym, lap pool, sauna and cold plunge. 

A team with Corcoran Sunshine Development Marketing, led by Angeli DeCecchis and Michele Hinojos, is heading sales at the development. A spokesperson for Corcoran Sunshine Marketing Group did not respond to a request for comment. 

GFP Real Estate and a group including Sorgente, ABS Partners and Nathan Silverstein paid $160 million for the property at a 2023 auction. Brodsky later bought a stake in the building.
