Sound Transit University of Washington Station
Architect: LMN Architects
Owner: Sound Transit
Knitting together multiple modes of transportation, the 156,000-square-foot Sound Transit University of Washington Station creates a unified solution for a problematic and incredibly busy Seattle intersection. A gateway to the university campus, it provides a wealth of above- and below-grade experiences.
The primary component of the project is the train platform, which sits 100 feet underground and is accessed by escalators and elevators from a two-level glass headhouse. Clean and visually economical, the structure greets commuters at multiple levels, and allows foot and bike traffic to access alternatives to the street. New bike ramps play a critical role in expanding Seattle’s bicycle commuter network and connect the station to a 27-mile rail trail.
"An aesthetically inspiring jewel that doubles as fantastic public art." ~ Jury statement
Design elements throughout the station create a sense of movement and connection with the urban fabric. On the mezzanine, green accents in the wall treatments reference a linear armature bearing light fixtures and elements of the public address system that winds through the circulation pathways creating a striking wayfinding element. As passengers head down to the platform, they pass through a 55-foot-tall circulation chamber and “Subterraneum,” a collaborative art installation that seamlessly blends architecture and sculpture to evoke the geological layers of soil that surround the station.
The station’s extensive mechanical systems are layered into the architecture, allowing design, artistic gestures, and daylight to take precedence. Hidden from public view are the massive emergency smoke ventilation system, track crossover, and maintenance spaces that consume nearly two-thirds of the total station area. Each end of the below-grade structure is anchored by an elliptical ventilation tower that provides supply and exhaust air.
Overall, the project solves many transportation and urban planning issues at once; each element was carefully considered as a component in the web of uses surrounding it. The result is a transit hub that beautifully navigates a very complex urban node.
"They have made descending deep into the earth pleasant, full of light and color and visual texture." ~ Jury statement
