45th Street Plaza


Upon its completion, this Class A office building with ground-floor retail was immediately recognized as a standout architectural gem in the neighborhood adjacent to University of Washington. Designed by Mulvanny/G2 Architecture, the six-story 45th Street Plaza is built of concrete and steel.

Among the tenants of 45th Street Plaza are Intel Research Seattle, the University of Washington, Washington State Employees Credit Union and Quiznos.

Office workers in 45th Street Plaza enjoy a vibrant street life filled with students, professionals, retirees and families in one of the city’s densest neighborhoods.

Convenient nearby amenities include major transit stops and a variety of retail shops, including Trader Joe’s and FedEx Kinko’s. 45th Street Plaza is near the historic Hotel Deca and is next to the site of a new business traveler hotel.

The building was completed in 2001.
