Why you should experience The Spheres in Seattle, Washington.
The Spheres is a groundbreaking architectural conservatory where South Lake Union's technological ambition, environmental innovation, and biophilic design converge around one of the world's most distinctive workplace environments.
Set along Lenora Street near 7th Avenue and just steps from Amazon Headquarters, this extraordinary glass conservatory anchors the heart of Seattle's innovation district, where tropical ecosystems, cutting-edge engineering, and visionary workplace design have redefined how people interact with nature in an urban environment. Three interconnected glass domes, soaring living walls, elevated walkways, rare botanical collections, and immersive gathering spaces create an environment unlike any other corporate campus on Earth. Opened in 2018, The Spheres demonstrate how architecture and nature can coexist to inspire creativity, collaboration, and well-being.

What you should know about The Spheres.
The Spheres is best known for housing more than 40,000 plants representing over 4,000 species from around the world, including the 55-foot-tall “Rubi”, among the largest living indoor ficus trees on Earth, creating one of the world's most biologically diverse indoor plant collections within a corporate workplace.
The collection was assembled by botanists and horticultural specialists who sourced rare and unusual species from cloud forests, tropical rainforests, and equatorial ecosystems across multiple continents. Sophisticated climate-control systems precisely regulate temperature, humidity, airflow, and daylight to replicate natural growing conditions for thousands of delicate plants that would otherwise be impossible to cultivate in Seattle's climate. Today, The Spheres have become an internationally recognized symbol of biophilic architecture, demonstrating how immersive natural environments can enhance creativity, wellness, and workplace innovation.
