Rainier Square Tower

At 850 feet tall and 58 stories, Rainier Square Tower is the second-tallest tower in Seattle. The building tapers as it rises on two sides, gracefully complementing the adjoining Rainier Tower. Leasable space includes 722,000 square feet of offices, 180 luxury apartments, 786 parking spaces on six below-grade levels and a full retail podium.

The tower is known for its use of the world’s first ever dual-plate steel and concrete core, which reduced construction by nine months, providing the speed of steel with the structural advantages of concrete. Additional unique elements include the world’s longest building maintenance unit (swing arm) at 150 feet, elevators built to much higher fire-egress standards (allowing one fewer stair) and the Northwest’s first sloshing dampeners to reduce building sway.
