Since 1984, Nike’s Worldwide Headquarters has continued to expand, grow and stretch on land near Beaverton, Oregon. The next phase of growth will include about 3.2 million sq ft of office, mixed-use and parking facilities, all expected for a 2018 completion.

The Nike campus, with a berm surrounding most of it and a lake in the center, features a wide range of uses. The Tiger Woods Center serves as a conference center used by athletes and businesses connecting with Nike, while sports fields, fitness facilities and a small museum merge with ample offices and a state-of-the-art—and secretive—research lab to all collaborate on the global giant that is Nike.

“Every day at Nike we dream up new ways to inspire athletes to expand their potential,” Mark Parker, president and CEO, says in a statement. “To do that, we relentlessly evolve how we inspire our own teams and design environments that foster chemistry and collaboration. Our expanding World Headquarters reflects the best of Nike’s culture—a place where we obsess the athlete and invent future products and experiences for consumers everywhere.”

That next phase of obsession will have a distinct design, if the renderings offered up by Nike serve as any example. A trio of Northwest-based firms, ZGF Architects, SRG Partnership and Skylab Architecture will guide design, while Portland’s Place Studio will provide landscape architecture services.

The new structures tie to the original campus master plan and link preexisting areas through open green spaces, paths, sports courts and fields. The architecture takes inspiration from human movement, speed and the strength and energy of competitions, Nike says.

Extensions into the landscape and connected interiors represent the power of teamwork and creativity, all while aiming for LEED Platinum certification with natural daylighting, passive chilled beams, closed-loop grey water treatment and more.

The Nike campus at One Bowerman Drive started with a land purchase in 1984. It opened in 1990. Expansion started nearly immediately, as the Nolan Ryan Building opened two years later. Then, in 2001, Nike doubled its footprint and incremental development of both buildings and land has remained constant over much of the last decade.
