One Vanderbilt

Part observatory, part immersive experience, part sensory space, and all views, Summit at One Vanderbilt opens in October.

At 1,401 feet, the glassy tower is the tallest office building in Midtown.

"It's understandable that there's a certain skepticism when New Yorkers hear promises about what development will do for them," Mayor de Blasio said.

An entire block of unexceptional buildings was demolished for this tower.
