While Amazon was dominating the news with its search for a city to host a second headquarters a few years ago, the tech giant’s first purpose-built campus was taking shape in Seattle’s Denny Triangle neighborhood (also known as the Denny Regrade for the leveling of its eponymous hill more than 100 years ago). Completed last summer, the 3.3 million-square-foot complex, designed by the local office of NBBJ, spans three blocks with six distinct buildings activated by public paths, verdant plazas, ground-floor shops, dining venues—even dog parks. The result is a dynamic workplace for employees that integrates into its urban setting with engaging places for the community and passersby.
