This residential high-rise is a tower of superlatives: it is the tallest residential building in the world, and having a width to height ratio of 1:15 the tower is also one of the most slender residential towers worldwide. It is the second tallest building in New York City, behind One World Trade Center, and ahead of the Empire State Building. When measured by roof height, however, 432 Park Avenue is the tallest building in New York, surpassing One World Trade Center by 32 ft (9.8 m). The structure follows the tube-in-tube principle comprised out of the core and outer high-strength concrete moment frame. The very regular facade pattern is interrupted at mechanical levels to avoid dynamic acceleration under certain wind conditions. A series of outriggers are located also on the mechanical levels to facilitate the interaction between core and outer moment frame.
