Exchange Building, Art Deco office skyscraper in downtown Seattle, United States

The Exchange Building is a 23-story, 275-foot Art Deco office tower at the central business district of Seattle, designed by John Graham & Associates and completed in 1930. Its reinforced concrete frame made it the second-tallest reinforced concrete skyscraper in the United States at the time. The facade carries geometric Art Deco ornament, and the building was awarded landmark status on April 20, 1990.

Designed by John Graham & Associates and completed in 1930, the Exchange Building was built to house the Seattle Stock Exchange. It was designated a city landmark on April 20, 1990, and won the Building Owners and Managers Association's Office Building of the Year award in 2002.

The building's name comes from the Seattle Stock Exchange it was built to house in 1930. Its early tenant roster read like a corporate directory of the era: General Electric, Standard Oil, Edison Lamp Works and Underwriters Laboratories. Later came Pacific Northwest Bell and the Municipality of Metropolitan Seattle; by 2016 Slalom Consulting, Deloitte Digital and Nuance Communications occupied space there.

The building is located in downtown Seattle along Second Avenue and features office spaces of varying sizes to suit different business needs. Visitors can easily view the exterior from street level to appreciate the Art Deco details on the facade.

At its 1930 opening, the Exchange Building was the second-tallest reinforced concrete skyscraper in the United States, after only one other. Its early tenant roster included General Electric, Standard Oil, Edison Lamp Works and Underwriters Laboratories.
