One Vanderbilt is a 1,401-foot supertall skyscraper that redefines the Manhattan skyline and the experience of Grand Central Terminal. Designed by KPF, the tower features a tapered form comprised of four interlocking volumes that spiral up to the sky. Its facade of terracotta and glass pays homage to the details of Grand Central, to which it is directly connected. The building includes "SUMMIT," a multi-sensory observation deck, and achieves the highest standards of sustainability.
