How much does Steinway Tower sway in wind?

As with any building over a certain height, high winds can potentially cause noticeable swaying. A building as tall and slim as the Steinway Tower, which comes in at 435m (1,428ft), could move as much as 0.9m (3ft) on the upper floors. This could be nausea-inducing, until you get used to it!



Steinway Tower (111 West 57th Street) in New York City is the world's most slender skyscraper, with a height-to-width ratio of 1:24. Because of its incredible thinness, the building is designed to sway as much as 3 feet (0.9 meters) at the very top during high-wind events. To keep this motion comfortable for residents, the tower features an 800-ton tuned mass damper at the top, which acts like a massive counterweight to counteract the wind's force. While the building is structurally perfectly safe, residents on the upper floors may still notice slight movements, such as water rippling in toilets or light fixtures swaying, during major storms. This "pencil tower" engineering is a marvel of 2020s architecture, utilizing high-strength concrete and steel to ensure that even with its extreme slenderness, it remains stable in the intense wind currents of the Manhattan skyline.
