Amazon created a green paradise in its new building in downtown Seattle, called the Spheres.

It’s part of a $4 billion investment that the company has made in its Seattle headquarters



Amazon is showing off its green thumb.

The company just took the wraps off the Spheres, called that because of their bulbous shape. Amazon collected plants from greenhouses around the world to take home to the building in downtown Seattle.

Rivers, waterfalls, and towering green walls are meant to take employees into a headspace as serene as the tropical forest the foliage tries to replicate. Workers cluster in "treehouses" to work and collaborate, surrounded by natural beauty. The building was designed by local Seattle-based architecture firm NBBJ.

The Spheres can hold about 800 working Amazon employees, who seem to be excited about it — time slots are already booked through April.

Here's what it's like inside the verdant structures.
