What is the name of Amazon's glass-domed plant-filled workplace in Seattle?

Amazon’s glass-domed, plant-filled workplace in Seattle is the Amazon Spheres.

The Amazon Spheres are three connected spherical conservatories forming part of Amazon’s headquarters campus in Seattle’s Denny Triangle. Designed by NBBJ with landscape design by Site Workshop, the domes combine employee lounges, meeting areas, workspaces, and retail facilities. They opened to Amazon employees in January 2018, with limited public access through tours and special programs.

The complex contains roughly 40,000 plants from around the world, including trees, vines, ferns, and carnivorous species. Its largest tree, a ficus nicknamed “Rubi,” is about 55 feet tall. The domes use more than 2,600 glass panels and are maintained at a warm, humid climate suited to the indoor rainforest.

A common mix-up is confusing the Spheres with nearby Amazon buildings such as Day 1 or Doppler. Those names refer to other parts of the Seattle campus; the distinctive conservatory itself is called the Amazon Spheres. The project was conceived as an example of biophilic design, bringing nature into a dense urban office environment.
