A Quick Overview of Rainier Square Tower
Rainier Square Tower is located at 401 Union Street, Seattle, Washington, in the heart of the city’s bustling downtown. The building is part of the Metropolitan Tract, a property owned by the University of Washington.
The tower’s unique features, including its sloping facade and cutting-edge construction techniques, have made it a symbol of modern architecture. It was developed by Wright Runstad & Company and designed by the renowned architectural firm NBBJ.
Construction began in October 2017, and the building was topped out in August 2019, with final completion in September 2020. The project cost an estimated $600 million.
Unique Design Features of Rainier Square Tower
Rainier Square Tower is not just another skyscraper; it’s a true innovation in design and engineering.
1. Sloping Facade
The tower’s most striking feature is its sloping appearance. Starting with a wide base, the structure tapers as it rises, giving it a distinctive wedge-like shape. This unique design was created to preserve the views of the adjacent Rainier Tower, which is known for its iconic “pedestal” base.
2. Steel Shear Wall Core System
Rainier Square Tower was constructed using an innovative steel shear wall core system. Unlike traditional methods that use rebar and formwork, this system relies on steel plates. This method significantly reduced construction time while providing excellent structural stability.
3. Mixed-Use Functionality
The building seamlessly integrates multiple uses:
- Office Space: 750,000 square feet of modern office spaces.
- Residential Units: Nearly 200 luxury apartments with stunning views of Seattle.
