This cluster of glass spheres enclosing a lush vegetated interior is now a Seattle icon.
The Spheres are a feature of a headquarters campus and one of the most distinct structures in downtown Seattle.
4EA teamed up with NBBJ to tackle some of the many challenging roofing and waterproofing conditions and help Find A Solution to achieve this one-of-a-kind design. The Spheres include a lush interior vegetated landscape above and alongside finished spaces, so accommodating the many features required out-of-the-box thinking and unique solutions. Interior features include intensive landscaping over multiple stories, an indoor river and waterfall, a massive vegetated green wall, and an exterior moat.
