Inside the Amazon Spheres: Seattle’s Urban Rainforest Under Glass
Step into the Amazon Spheres—where innovation, architecture, and nature converge in the heart of Seattle.
Amazon Spheres: Seattle’s Visionary Urban Oasis
Three shimmering glass domes, nestled in the South Lake Union neighborhood, anchor Amazon’s sprawling $4 billion urban headquarters. Known as the Amazon Spheres, these futuristic orbs offer a striking visual statement and function as a bold experiment: blending botany, architecture, and the latest in workplace design to cultivate both collaboration and creativity in the heart of Seattle. The tallest dome—reaching an impressive 27 meters (about 90 feet)—shelters lush, riverine landscapes and vertical gardens under a microclimate that feels plucked straight from Costa Rica’s Central Valley. More than mere showpieces, the Spheres are living proof that innovation and nature can thrive together—even amid the Pacific Northwest’s steel-and-glass cityscape.
The Story Behind the Spheres
Conceived as a radical departure from traditional office environments, the Amazon Spheres sprang from an idea: urban workers need a stronger connection to nature. In a world dominated by screens and cubicles, Amazon embarked on this ambitious project to create a workspace where employees could “think and work differently, surrounded by plants.” The Spheres offer a living laboratory—both a physical and philosophical centerpiece for Amazon’s urban campus and a new model for biophilic design in a bustling metropolis.
- Original vision: A single, curved glass structure overflowing with plants and tall trees—a garden for innovation.
- Construction timeline: Spanning from February 2013 to January 2018, with completion in December 2016 and interior planting finished by the opening date in January 2018.
- Design partner: Global architecture firm NBBJ, known for blending cutting-edge design with sustainable urbanism.
Design and Architecture: Form Meets Function
The Amazon Spheres comprise three interconnected geodesic domes, constructed from a dazzling patchwork of over 2,600 glass panes. Each sphere varies slightly in size, but together, they enclose more than 65,000 square feet of workspace and public area.
- Geodesic engineering: The structure leverages a pentagonal hexacontahedron geometry, maximizing light and space in every direction.
- Sustainable integration: Specialized glass maintains heat while optimizing sunlight for the interior ecosystem, helping establish a stable, humid climate year-round.
- Natural daylight: The atrium-like interiors provide expansive natural light, nurturing the thousands of botanical specimens inside.
- Inspired by history: Echoes of the New York Ford Foundation’s famous atrium and Buckminster Fuller’s visionary domes can be felt in the Spheres’ quest for accessible, controllable “interior nature.”
The Living Collection: A World-Class Botanical Showcase
Home to more than 40,000 plants from over 30 different countries, the Amazon Spheres function as both a conservatory and a research space. The carefully curated plant palette skews toward tropical cloud forest species, simulating an environment more common to Central America or Southeast Asia than the temperate, rainy Pacific Northwest.
- Climatic control: Maintained at an average daytime temperature of 72°F (22°C) and 60% humidity, the climate inside feels perpetually like a spring morning in the tropics.
- Botanical diversity: The collection features rare palms, lush ferns, technicolor orchids, bromeliads, epiphytes, and carnivorous pitcher plants—some found nowhere else in the region.
- The Living Wall: A 60-foot vertical garden supports some 25,000 individual plants, continually watered by a gentle misting system to mimic cloud forest conditions.
- Unique features: A “paludarium” tank blends aquatic and terrestrial life, evoking the flooded basins of the real Amazon. Occasionally, visitors might catch a waft from a blooming corpse flower—famed for its pungent aroma reminiscent of decaying flesh.
Experiencing the Spheres: What to Expect Inside
Entering the Amazon Spheres is like stepping into a lush, futuristic terrarium—a world apart from the surrounding city. The experience is multisensory, with the scent of orchids, the gentle splash of water features, and filtered sunlight giving the entire space an enchanted, otherworldly feel.
- Ambient conditions: Warm, slightly humid air greets you, notably more comfortable than outside, even on Seattle’s rainiest days.
- Ground rules: Visitors are kindly reminded not to touch or lick the plants—a surprisingly necessary rule.
- Microclimates: The domes feature varying habitats, from riverine jungle to misty heights, with temperature shifts between day and night.
- Workspaces: Employees enjoy numerous nooks—suspended walkways, tree-house-like platforms, open benches, even a central cafe—to foster informal meetings and quiet contemplation.
Work and Wellness: Rethinking the Modern Office
The Spheres offer Amazon employees a remarkable workplace where nature triggers creative thinking and well-being. This curated environment encourages connection, collaboration, and a “think outside the cubicle” ethos that aligns closely with Seattle’s innovative culture.
- Employee benefits: Over 800 “Amazonians” can occupy the Spheres at once, escaping the confines of standard offices for a setting proven to reduce stress and spark innovation.
- Workspace diversity: From standing desks among ferns to quiet alcoves surrounded by foliage, the Spheres offer an array of environments.
- Research on biophilia: Studies link exposure to plants with improved mood, creativity, and productivity—core goals for Amazon’s workplace designers.
Public Access: How to Visit the Amazon Spheres
Although the Spheres primarily serve Amazon employees, the company aims to engage the greater community by offering limited public access. The domes open their doors to the public two Saturdays each month by online reservation—appointments are released 30 days in advance and often fill quickly due to high demand.
- Admission: Visits are free but require a reserved time slot, with entry permitted only during designated weekends.
- Tour style: Guests navigate at their own pace along designated paths, interacting with knowledgeable Spheres Ambassadors stationed throughout.
- Café experience: Visitors—and employees—can refuel at General Porpoise, helmed by James Beard Award-winner Renee Erickson. Expect locally roasted coffee and artisanal donuts amidst the greenery.
Innovation in Urbanism: The Spheres and the City
Amazon’s campus is notable for standing in the city’s core—unlike other tech giants that gravitate toward suburban campuses. By rooting its headquarters in downtown Seattle’s Denny Regrade district, Amazon has asserted a new vision for urban development: dense, interconnected, and thoroughly modern.
| Feature | Amazon Spheres | Traditional Office Tower |
|---|---|---|
| Connection to Nature | Direct, immersive (40,000+ plants) | Minimal (few potted plants, views only) |
| Design Aesthetic | Organic, glass domes | Rectilinear, steel and concrete |
| Workspaces | Flexible, informal, collaborative | Fixed, formal, segmented |
| Climate Experience | 72°F, humid, tropical | Conditioned, dry, temperate |
| Urban Impact | Iconic, accessible, urban anchor | Standard, inward-facing |
Fun Facts and Unique Features
- Paludarium: A blend of aquarium and terrestrial habitat, designed to evoke South America’s flooded Amazonian forests.
- Invisible technology: Environmental control systems—like fans and misters—are artfully hidden within “tree trunks” and foliage, maintaining a natural aesthetic.
- Living laboratory: The Spheres participate in ongoing plant health and conservation research, advancing horticultural knowledge far beyond their walls.
- Eco-connections: Vertical plantings and mist-based watering techniques inform broader urban landscaping trends and inspire home garden innovation.
Inspiration for Home and City Design
What lessons can the average visitor or home designer take from the ambitious Spheres project? The benefits of immersive, plant-rich environments apply at any scale. Homeowners can adapt the following strategies inspired by the Spheres:
- Incorporate living walls or large clusters of houseplants to connect with nature indoors.
- Mimic the Spheres’ strategic use of natural light—maximize glass, skylights, or light wells for lush interior spaces.
- Experiment with bio-diverse plant selections: mix ferns, bromeliads, and moisture-loving species for texture and interest.
- Consider the psychological benefits—plants can lower stress, improve air quality, and boost productivity throughout home and workplace settings.
