The Amazon Spheres are three spherical conservatories that are part of the Amazon headquarters campus in Seattle. Designed by NBBJ and landscape firm Site Workshop, the three glass domes are covered in pentagonal hexecontahedron panels and serve as an employee lounge and workspace. The domes, which range from three to four stories tall, house 40,000 plants as well as meeting space and retail stores. They are located under the Day 1 building on Lenora Street. The complex opened to Amazon employees and limited public access on January 30, 2018. The spheres are reserved mainly for Amazon employees, but are open to the public through weekly headquarters tours and an exhibit on the ground floor.
The spheres are located along Lenora Street between 6th and 7th Avenues, under Day 1 in Amazon’s Seattle headquarters campus. The three intersecting spherical domes range from 80 to 95 feet (24 to 29 m) in height and take up half of a city block. They use over 2,600 panes of glass and 620 short tons (560 t) of steel, arranged with five-sided panels of a pentagonal hexecontahedron.
The largest sphere, in the center, is four stories tall and has 3,225 square feet (299.6 m2) of space; it houses the cafeteria, stairway, elevators, and bathrooms. The stairwell shaft is covered by a four-story “living wall” with 25,000 plants, including carnivorous species from Asia. The spheres have meeting spaces, tables, and benches that can seat a total of 800 people.
