The tallest of the three interconnected spheres, called Amazon Spheres by the company, will be 90 feet high and 130 feet in diameter, and is planned to include a botanic garden of waterfalls and treehouse-like spaces overlooking tropical gardens. The structures are expected to begin being used by employees in early 2018. (AP Photo/Elaine Thompson), APTOPIX
