NBBJ’s design for Amazon’s new and massive Seattle headquarters was revealed in greater detail this month. Renderings of the project’s street level presence, unveiled in a meeting with the city’s Design Review Board (DRB) on August 14, show asymmetrical towers, mid-rise buildings of varying size, and mid-block open spaces, representing a scale of development unprecedented in Seattle’s history.

The 3.3-million-square-foot project spanning three city blocks is on track to start construction next year. It will consolidate Amazon’s currently dispersed operations in leased buildings into an owner-developed campus between Seattle’s commercial core and the neighborhood of South Lake Union. The project’s location, known as the Denny Triangle, is currently an under-developed, in-between space, comprised largely of parking lots and car dealerships.
