A new condo tower designed by Chicago-based Adrian Smith + Gordon Gill was announced late last year, but details of the super-tall tower have been scant. The 88-story tower at 215 West 57th Street will be one of New York City’s tallest buildings, reaching up to 1,550 feet. That means it will top the Empire State Building’s measly 1,454 feet and come in second only to the 1,776-foot-tall One World Trade Center. (If you’re paying attention to the spire / antenna semantics game ongoing at One World Trade, AS+GG’s new tower would beat its midtown rival by a little over 200 feet.) Adrian Smith is no stranger to designing soaring skyscrapers—he designed Dubai’s Burj Khalifa while working at SOM, still the tallest tower in the world. The architects declined to comment further about the tower.
