As AN reported in our latest West Coast issue, designs for the Amazon headquarters in downtown Seattle have gone through another revision since this past May. Though still channeling greenhouses and conservatories, renderings reveal an update to the three interconnected domes on Block 19 that architecture firm NBBJ has dubbed “conjoined Catalan spheres.” With a skin of white painted steel, the new design has moved beyond more traditional cross-hatching, and now nods to the pentagons of a soccer ball. But these forms are expanded and pushed to create an irregular pattern that exerts a more organic geometry. Read more about the project in AN‘s article or check out an expanded gallery of renderings below.
