Clean, unornamented lines climb 17 stories from a solid granite base at 801 2nd Ave, in the heart of Seattle's Central Business District. This is the Norton Building, an early modernist office tower in the International Style that opened in 1959 as one of the city's first private office buildings after World War II. It was also an early national example of pre-stressed concrete construction, and the City of Seattle made it an official landmark in 2009.
Why It Turned Heads in 1959
Picture downtown Seattle in the late 1950s, when the business core had seen little new private office construction since before the war. Into that lull came a tower with clean, unornamented International Style lines, a clear signal that the city's business district was heading in a fresh direction. Its doors opened on October 30, 1959.
Look past the facade and the engineering tells its own story. The Norton Building was among the first buildings in the United States to use pre-stressed concrete, a technique that pairs concrete with tensioned steel so it can carry heavier loads. That choice is a big part of why preservationists value the building today.
