Amazon built South Lake Union, or more precisely, Amazon transformed it into the glass-tower campus you see now. In 2007, Amazon announced it would consolidate its campus in South Lake Union, then an industrial district of warehouses, auto shops, and the South Lake Union Trolley running along Westlake Avenue. The company invested billions in building a corporate campus of glass towers around the lake's southern shore, bringing tens of thousands of employees and hundreds of millions of dollars in construction spending into a neighborhood that had been functionally invisible for decades.
The transformation was swift and total: warehouses became biotech labs, parking lots became parks, the trolley was revived and extended. Paul Allen, Microsoft's co-founder, had already invested heavily in the neighborhood through his Vulcan development company, positioning it as a biotech hub before Amazon arrived. The result is one of the most dramatic urban transformations in American history, accomplished in less than a decade.
Not everyone sees it as unambiguously positive: housing prices citywide rose sharply, longtime residents were displaced from adjacent neighborhoods, and the monoculture of tech wealth reshaped the city's character. South Lake Union is the most vivid demonstration of what happens when a single company decides to inhabit a city.
