You can take Amazon out of the jungle, but it'll just create one elsewhere -- at least that's what the company is planning for its inner-city Seattle office complex. A tweaked proposal for Amazon's three-block development, named "Rufus 2.0," was run by Seattle's Design Review Board yesterday, and it now includes a huge biodome structure with the notion that a "plant-rich environment has many positive qualities that are not often found in a typical office setting." It's five floors feature places to get work done, "dining, meeting and lounge spaces," a pair of shops serving the general public and, of course, lots of plants and trees. We've included a few more renders of the multi-bubble glass house after the break, and you'll find even more eye-candy in the source PDF. Forget the platform wars -- the competition for the coolest next-gen campus is on.
