1201 Third Avenue
It was the first major office building built under Seattle's 1985 downtown zoning plan, largely implemented in response to the Columbia Center, which called for height limits, interesting profiles, and height and density bonuses for public amenities to create a 24-hour downtown.[6] By providing the amenities the designers were able to add 28 stories to the tower and almost double the base floor area ratio of the site.[7] The New York Times named it one of the three best new office buildings in the United States in 1988, and in the May 1989 issue of Architecture Magazine Walter McQuade called it "perhaps the best recent addition to any U.S. skyline".[12] The Puget Sound Regional Council, a metropolitan planning organization, moved its headquarters to the fifth floor of 1201 Third Avenue in January 2024.[13] Perkins Coie, an original tenant, plans to move to the nearby Russell Investments Center in 2025 and vacate their space at 1201 Third Avenue.
