British/Ghanian architect Sir David Adjaye's firm has revealed plans for a very ambitious new skyscraper for New York City. Named Affirmation Tower, it's slated to become one of the Western Hemisphere's tallest buildings and will feature a striking cantilevering design that looks a little like an upside down skyscraper.
Details on the project are still light at this early stage and we've no confirmation yet that Affirmation Tower is definitely going ahead. Assuming it does though, it will rise on a prominent Manhattan plot just a block away from the Hudson Yards mega project and the High Line.
The skyscraper's overall form will be made up of a series of blocky sections stacked on top of each other, creating a stepped profile that appears to increase in width as it rises. It will reach a very impressive height of 1,663 ft (506 m) and though described in the press release as the Western Hemisphere's tallest building, that honor will actually remain with the One World Trade Center, which reaches a height of 1,791 ft (546 m). Still, Affirmation Tower is certainly no slouch in the height stakes and will be the west's second-tallest skyscraper and 11th in the world's-tallest list, as of writing. It will include commercial office space, as well as two hotels, the headquarters of the NAACP, an observation deck, and a skating rink.
The project also involves the Peebles Corporation, McKissack & McKissack, Exact Capital, and Steven Witkoff. Since winning the RIBA Gold Medal in late 2020, Adjaye Associates has had a very busy period, unveiling plans for 101 hospitals, a mud library, and a luxury collaboration with Aston Martin.

You are only allowed to build so much floor area per building. The higher floors likely lease for more money so the more of the floor area you can build higher up, the better the economic return to justify all the extra structure. Similar to those super tall residential towers that pay for the insane slenderness with wrap-around views.
For the past hundred-ish years towers in New York have had to get smaller as they got taller in a 'wedding-cake' style due to zoning rules to keep the streets from being in constant shadow. Looks like they have somehow gotten around those restrictions.
