Seattle’s design review board has unanimously approved the three biodome scheme for the NBBJ-designed Amazon headquarters. The five-story building will include flexible brainstorming and work areas filled with plants and trees, while the ground level will include retail space and public viewing spots. Planned for the block is also an Amazon office tower of up to 38 stories, as well as a neighboring public park that will include a dog run area.

The steel motifs that span the glass biodomes were modified since the August revisions to appear more buoyant and open. Retail space was expanded to 18,000 square feet and the update also added a cycle path.It will take the city approximately four to six weeks to issue a building permit.When complete, the Amazon headquarters will encompass three blocks in the Denny Triangle area. Construction of the the first out of three phases is underway.
