Midtown East is about to lose three buildings and gain a 1,600-foot tower. 350 Park Avenue cleared its final city approval on a 48-to-0 City Council vote, and demolition of the structures on the site is set to begin in the second quarter of 2026. When it tops out, the 62-story Foster + Partners design will be one of the tallest office towers in New York.

Project Scope

The tower delivers about 1.8 million square feet of Class A office space with room for roughly 6,000 workers. It’s all-electric, with a high-performance facade, outdoor terraces, and biophilic design woven through the floors. The form steps back and tapers as it rises, a nod to the older Park Avenue towers around it. Vornado Realty Trust, Rudin, and Ken Griffin are developing the roughly $4.5 billion project, with completion anticipated in 2032.

Why It Matters

The anchor tells the story. Citadel and Citadel Securities will take at least 850,000 square feet, a commitment that underwrites a tower this expensive in a market where speculative office has gone quiet. That’s the post-pandemic pattern in office construction: trophy buildings with a named anchor get built, while everything else waits. An all-electric supertall is also a wager that operating without on-site fossil fuel is now the premium standard for New York office. Building it through the back half of the decade means absorbing the steel and metal cost pressure hitting every tall-building budget right now. Design details are published by Foster + Partners.
