A new supertall has reached its full height on Fifth Avenue. 520 Fifth Avenue, developed by the New York firm Rabina, has topped out at 1,002 feet across 88 stories — making it, by the developer’s account, the tallest mixed-use building on the Fifth Avenue corridor. The Kohn Pedersen Fox-designed tower, built by Suffolk Construction, was on track for completion around the middle of 2026.

The numbers

At 1,002 feet, 520 Fifth clears the 300-meter threshold that the Council on Tall Buildings and Urban Habitat uses to classify a “supertall.” It is not one of Manhattan’s record-setters — Central Park Tower, 432 Park Avenue, One Vanderbilt and 111 West 57th Street all rise higher — but none of those sits on Fifth Avenue itself, which is what lets Rabina claim the “tallest mixed-use on Fifth” distinction.

The program inside is a blend rarely attempted at this height: 100 condominium residences ranging from one- to four-bedrooms, a set of full-floor office units on lower floors, and a private members’ club devoted to hospitality, recreation, fitness and wellness. The residences carry ceiling heights up to roughly 14 feet and sightlines across Bryant Park toward the Empire State Building and, to the north, Central Park.

A rare condo bright spot

The tower topped out into a Manhattan new-development market that has been uneven, but 520 Fifth’s sales have outpaced much of the field. Sales launched in April 2025; by early 2026, Rabina reported that roughly 70% of the residences had found buyers — a brisk pace for a building still under construction. A penthouse was marketed in the eight-figure range.

That absorption tracks with the broader top-of-market resilience that brokers have reported through 2025 and into 2026. The luxury segment has held up even amid higher interest rates and political uncertainty, with weekly contract counts at the $4-million-and-up tier running at or above the prior year, according to Olshan Realty’s tracker. A new, supply-constrained product on a marquee address has been one of the few categories able to command pricing power.

KPF on Fifth Avenue

For KPF, 520 Fifth extends a run of tall New York work that includes One Vanderbilt and the Hudson Yards towers. The firm’s design for 520 leans on a slender, gridded facade and a stepped crown, and the project landed on the architecture press’s list of most-anticipated American buildings completing in 2026.

The site, at the corner of Fifth Avenue and 43rd Street, sits a block from Bryant Park and the main branch of the New York Public Library — one of the most heavily trafficked stretches of Midtown. Assembling a supertall footprint there required years of site work; the superstructure was poured by Suffolk with formwork from Doka, the Austrian engineering supplier that documented the job as one of its New York references.

What topping out signals

“Topping out” marks the moment a building’s structural frame reaches its highest point — it does not mean the tower is finished. Facade installation, mechanical systems, interiors and amenity build-out all follow. For 520 Fifth, the milestone put the project on a glide path to a mid-2026 completion and the start of closings for the buyers who signed contracts over the prior year.

The building joins a cluster of slender Midtown towers — the so-called “supertall” generation that reshaped the skyline over the past decade — but with a programmatic twist. Where many of its neighbors are single-use luxury condos or pure office towers, 520 Fifth’s mix of homes, offices and a members’ club reflects a post-pandemic bet that the most valuable Midtown square footage is the kind that does more than one thing.
