Design: Amazon Building Treehouses for Employees

Tech giant Amazon is in the middle of a massive and ambitious build project for its new downtown Seattle headquarters, and the edifice will feature—get this—treehouse-like meeting rooms for employees. The new Amazon building is comprised of three conjoined glass-and-steel orbs, which Amazon calls "Spheres," and will house around 3,000 different species of plants, some of which are endangered. There space will also feature suspension bridges, an indoor creek, a 45-foot-tall fig tree, and a five-story garden wall.

Amazon is growing much of the greenery themselves, and plans to open the new space sometime in 2018. It will only be available to Amazon employees, though the retail giant and e-reader pioneer is considering opening the venue to public tours at some point in the future. Looks like the Space Needle and Pike Place fish market will have some new competition for the role of the Emerald City's preeminent tourist attraction.
