Architectural Innovation: Amazon's Biomorphic Spherical Headquarters in Seattle | sustainable architecture |

On Tuesday, the online everything store submitted a new proposal for offices in downtown Seattle, featuring three biomorphic, spherical buildings.

The central element of NBBJ’s proposal for Amazon’s headquarters is a trio of conjoined Catalan-sphere modules, each built with a structural-steel skeleton. According to the proposal, which is the second submission to reach Seattle City Hall, these spheres would range from 80 to 95 feet in height and contain five floors of office space. The rounded, pentagonal facets of the spheres would meet in star-shaped intersections.
