Amazon Spheres

The Amazon Spheres are three spherical conservatories comprising part of the Amazon headquarters campus in Seattle, Washington, United States. Designed by NBBJ and landscape firm Site Workshop, its three glass domes are covered in pentagonal hexecontahedron panels and serve as an employee lounge and workspace. The spheres, which range from three to four stories tall, house 40,000 plants, as well as meeting space and retail stores. They are located adjoining 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. https://en.wikipedia.org/wiki/Amazon_Spheres

• Design.
  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 complex, nicknamed "Bezos' balls" by the media, has become a recognizable landmark and tourist attraction for the Denny Triangle area since the beginning of its construction. The structure has been compared to the city's iconic Space Needle, built as a futuristic landmark for the Century 21 Exposition in 1962. It was designed with influences from biophilic design, incorporating nature into the built environment.
• The revised design by NBBJ, which had been in development since 2012, was unveiled in May 2013 to a mixed reaction from the city's project design review board. While hailed as a bold design, it was criticized for the lack of rain protection, public access, and the amount of energy needed to climatize the facility. In August, NBBJ released an updated design that replaced the supporting steel structures under the glass with organic forms called "Catalan spheres". The city's design review board approved the design in October 2013, after slight changes to the understructure were made.

The Catalan solids are the dual polyhedra of Archimedean solids. The Archimedean solids are thirteen highly-symmetric polyhedra with regular faces and symmetric vertices.[1] The faces of the Catalan solids correspond by duality to the vertices of Archimedean solids, and vice versa. https://en.wikipedia.org/wiki/Catalan_solid
