UK architecture studio Foster + Partners has unveiled its design for a tiered, 62-storey supertall skyscraper on Park Avenue in New York.

Located at 350 Park, the supertall skyscraper will rise approximately 1,600 feet high (487 metres), holding office spaces and a public plaza at ground level.

Renderings show a tiered tower made up of rectangular volumes that increase in height across the tower's width, with the tallest sitting at 62 storeys. A terrace sits on top of each level, while the tower rests on a double-height base supported by pillars.

"The tower will feature floor-to-ceiling glass, landscaped terraces, and a stepped configuration to create an iconic, distinctive skyscraper," said the team.

The public plaza underneath will contain green space, seating areas, art displays and "opportunities for local businesses".

White, stone-clad columns will line the street-level space, and reach upwards between the glass panelling to separate each of the building's rectangular volumes into divided units on the facade.

The building will include a "high-performance building envelope" and use "resilient materials" as sustainable design strategies.

Developed by Ken Griffin, Vornado Realty Trust and Rudin, the 1.8 million square foot (167,225 square metres) project will "energize Midtown Manhattan" according to New York City mayor Eric Adams.

"Home to more than 6,000 jobs, this project will build on our continued efforts to energize Midtown Manhattan as the world's most important business address and an economic engine for working-class New Yorkers," said Adams.

The global investment firm Citadel is set to occupy 850,000 square feet (78,967 square metres) as "anchor" tenants.

The project is part of a wider initiative by Mayor Adams to "imagine Fifth Avenue as a more appealing district for residents, workers, and visitors," said the team.

It is set to begin the city's public review process in early 2025.

It is the newest in the studio's additions to the storied New York City avenue. Foster + Partners is currently working on a JPMorgan Chase headquarters at 270 Park Avenue – which can be seen in the background of renderings of 350 Park – and completed a 47-storey tower at 425 Park Avenue in 2022.
