Tallest Building in America— outside of NYC and Chicago

Signature Tower
Nashville, Tennessee

This 1,057-foot-tall residential condominium-hotel tower will dominate the Nashville skyline. The luxurious 70-story tower offers 58 floors of condominiums on the upper floors and a boutique hotel on the lower floors.

The owner’s wish for unobstructed views drove the structural concept, which relies on post-tensioned flat plate floors, and an outrigger-braced concrete core, with eight outrigger walls spanning from core to perimeter at three levels up the height of the tower.

The tower will include nine levels of below-grade parking, which were closely coordinated with the tower’s structural system to maximize efficiency and economy. The tower cantilevers 1,167 feet from the base to the top of the spire, resulting in a slender 8.6:1 aspect ratio. The 200-foot-tall steel spire will have a damper to reduce accelerations in the uppermost occupied levels.
