Amazon planning giant greenhouse offices for its new Seattle campus

Rather than being decorative, the greenhouse will serve as a work space.

From The Verge:

The five-story complex will contain office space, meeting rooms, lounge areas, in-house dining, and publicly-accessible retail spaces. It makes up a tiny portion of Amazon's planned "Rufus" campus, situated in a landscaped park between the three main 37-story office towers. If the proposals go through, Amazon's office / greenhouse mashup will likely become an iconic street-level structure in Seattle.
