Amazon Spheres

About
What It Is
The Amazon Spheres are three interconnected glass conservatories forming part of the Amazon headquarters campus in the Denny Triangle neighborhood of Seattle, Washington [2]. Designed by architecture firm NBBJ and landscape firm Site Workshop, the domes range from 80 to 95 feet tall and are clad in over 2,600 glass panes arranged in a pentagonal hexecontahedron pattern [2]. The complex opened on January 30, 2018, and functions primarily as an employee workspace and lounge, while also offering limited public access through tours and a ground-floor visitor center [2].
Activities & Experiences
Visitors can explore Understory, a free public exhibit and visitor center located on the ground floor beneath the spheres, where they can learn about Amazon and the building itself [1][2]. Public access to the interior of the spheres is available through weekly guided tours of the Amazon headquarters campus and a twice-monthly weekend reservation program [2]. Inside, guests encounter more than 40,000 plants from 50 countries, divided across three domes representing Old World and New World cloud forest regions, including a four-story living wall housing 25,000 plants and carnivorous species from Asia [2]. The largest specimen is a 55-foot Ficus rubiginosa tree known as Rubi, lifted into the structure by crane in 2017 [2].
Practical Access
The spheres are located along Lenora Street between 6th and 7th Avenues in Seattle, adjoining the Day 1 building [2]. The Understory visitor center is free to enter [1]. Interior access for the general public requires participation in the weekly headquarters tours or the twice-monthly weekend reservation program [2]. No visit duration, parking details, or transit information are provided in the sources.
Restrictions
The spheres are reserved primarily for Amazon employees; general public access to the interior is limited to scheduled tours and the reservation-based weekend program [2]. The facility was temporarily closed to the public during the COVID-19 pandemic [2]. No additional restrictions are noted in the sources.
What Makes It Distinctive
The Amazon Spheres house more than 40,000 plants from 50 countries, maintained at a constant 72 degrees Fahrenheit and 60 percent humidity, creating a functioning cloud forest environment inside a corporate headquarters in an urban setting [2]. The structure has become a recognized landmark in Seattle, drawing comparisons to the Space Needle for its architectural ambition [2]. The combination of a working biophilic workspace, a curated living plant collection spanning over 1,000 species, and free public access through Understory makes it an unusual intersection of corporate architecture, botanical conservation, and public engagement [1][2].
