Amazon Spheres

A set of three gigantic glass domes, built with pentagonal hexecontahedron panels serve as an employee lounge area at the Amazon headquarters. The conservatories also house 40,000 plants, a cafeteria, elevators, and bathrooms. The largest sphere is four stories tall. To take care of the plant species from over 40 countries, Amazon hired a full time horticulturalist. You don't have to be an employee to see the interior; navigate to seattlespheres.com to view the current schedule for visitor tours. (Submitted by Kin Vong)
