Amazon has big plans for its new campus. Big, sphere-shaped plans. The company revealed earlier this month that it will build a biosphere in Seattle, a 65,000-square-foot structure made up of three domes, where the temperature will always be a perfect 68 to 72 degrees, Fast Company reports. The planning document says the biosphere "will be visually reminiscent of a greenhouse or conservatory," and will be able to house "mature trees."
The 80- to 95-foot-high glass-and-steel structures will also incorporate "dining, meeting, and lounge spaces" on their five floors of workspace. There will be other, not-as-eye-catching buildings, too: The Seattle Times reports that Amazon purchased three downtown blocks last year, and wants to build 3.3 million square feet of office space there, including a few high-rises in the 37- to 38-floor range. Scribd has the proposal and a picture.
