175 Park Avenue (Project Commodore)

New York’s next supertall wants to replace a Hyatt. 175 Park Avenue, still widely known by its working name Project Commodore, would rise 1,581 feet on the block beside Grand Central Terminal, on the site of the existing Grand Hyatt. RXR Realty and TF Cornerstone filed permits in April 2026 for a 95-story tower, a jump up from the previously announced 83-story scheme, putting the building on track to rank among the tallest in the United States.

Project Scope

Skidmore, Owings & Merrill designed the tower, and its defining feature is structural rather than decorative: an exposed steel lattice that carries the loads on the building’s exterior, freeing the interior of columns and giving the facade its diagonal bracing pattern. The program runs nearly 3 million square feet, weighted heavily toward Class A office space, with a Hyatt hotel occupying the upper floors and retail at the base and below grade. AECOM Tishman is the general contractor; WSP is handling structural engineering.

The location is the entire argument. The tower sits directly on top of one of the densest transit nodes on the continent, with Grand Central’s commuter rail, the subway, and now the LIRR’s Grand Central Madison feeding straight into the block. For a tenant betting on getting workers back to a desk, an address you can reach without ever stepping outside is a hard one to beat.

Why It Matters

Midtown East spent the last decade rezoning itself to allow exactly this: bigger, denser towers clustered around the Grand Central transit core, built in part to fund public-space and transit upgrades. 175 Park is the rezoning’s marquee result. A column-free, transit-stacked supertall is a direct bet that premium office space in the right location still commands a premium, even after years of headlines writing off the sector.

That bet isn’t risk-free. The permits are filed, but construction depends on financing and tenant commitments lining up, and a tower this size is exposed to both. It joins a Midtown cluster that already includes One Vanderbilt a block away. If it gets built as drawn, 175 Park reshapes the Manhattan skyline and hands the city its tallest office tower. The honest status, for now, is that the drawings are ready and the money has to follow.
