520 Fifth Avenue has officially sold out, with the 88-story, 1,002-foot supertall beside Bryant Park putting its final condominium, unit 44A, under contract and closing out all 100 residences after a sales launch in April 2024.

Rabina counts it as the fastest sellout of a 100+ unit condominium in New York since 2014 and the highest price-per-square-foot sellout of any large-scale new development launched since 2015, a campaign that moved more than 90% of the homes in its first 12 months and finished on a tower that is already built and already closing.

Rabina developed the tower with Kohn Pedersen Fox on the architecture and Charles & Co. on the interiors, and Corcoran Sunshine Marketing Group led sales. Construction wrapped in August, when the supertall finished above Bryant Park, and closings began earlier this year.
The 100 condominiums take the upper 40 stories, stacked above roughly 25 floors of boutique Class A office space and ground-floor retail. That puts every home more than 400 feet above the street, with views across Manhattan and out toward its rivers. The residences run from one to four bedrooms.

At the top, Penthouse 88 is the amenity suite, now complete. It is designed as a collection of private rooms rather than a conventional amenity floor: a glass-walled solarium, a lounge, a dining room, a library, and a game room, each with panoramic skyline views. The building also holds Moss, a private members' club running 40,000 square feet across four floors, and its dining, wellness, and cultural programming gives the tower a hospitality layer alongside the offices and the homes.
The tower sits on Fifth Avenue between 43rd and 44th Streets, near Grand Central Terminal and the New York Public Library. Kohn Pedersen Fox is also behind 343 Madison Avenue, rising now in Midtown East, and Citadel's 350 Park Avenue is rising now as well, set to deliver in 2032. Rolex's David Chipperfield-designed headquarters in Midtown is now open. Down the avenue in NoMad, 262 Fifth Avenue, Fifth Avenue's tallest all-residential tower, is now open and has listed a $20 million duplex.

The office floors are filling alongside the condos, with more than 50% of the boutique space leased, another roughly 20% being finalized, and asking rents starting above $200 per square foot. Tenants include Ancient, JAB Holding Company, Texas Capital, Headlands Technologies, Abrams Capital, MFA Financial, and 1823 Partners. Five tenants have taken occupancy, with fit-outs progressing on additional floors and JLL leading the leasing. Josh Rabina, the firm's president, has framed the tower as an effort to bring residential, office, and hospitality together at a single Midtown address.
