Vulcan Block 52e, Amazon Headquarters | Seattle

Vulcan’s Block 52e adds a new 12-story, Class A Office building with four levels of below-grade parking to the growing South Lake Union neighborhood. The lowest level of parking is six feet below the water table, which required creative strategies for dewatering. The first four floors form a podium element approximately 45 feet high upon which eight office tower floors rest. The podium terrace design incorporates numerous green roof amenities and outdoor seating elements. Above-grade floors are massed toward the north end of the site, forming a signature Vulcan public open space at grade level along Thomas Street. Extensive preconstruction services included comprehensive structural systems design analysis to determine the most cost effective yet flexible option for meeting tenant requirements.
