BEAVERTON, OR — Nike, Inc. in 2016 announced its plan to expand its World Headquarters facility in Beaverton; on Sunday, July 16, the Oregonian offered an estimate for the expansion's cost based on input from real estate and construction company sources.

To add roughly 3.2 million square feet of office, mixed-use and parking facilities to its Beaverton campus, located at One Bowerman Dr., Oregonian sources estimate Nike will spend more than $1 billion — though the Oregonian added that Nike officials have yet to comment on any dollar amount. The company has expanded the Beaverton campus exponentially since the land it's on was first purchased by Nike in 1984, and according to its website "the new structures reinforce the original campus master plan and link to preexisting areas through open green spaces, paths, sports courts and fields, and are positioned for fluid future growth."

"Every day at Nike we dream up new ways to inspire athletes to expand their potential," Nike President and CEO Mark Parker said in an April 2016 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."

In a letter written this past May with co-founder and chairman emeritus Phil Knight, Parker expresses gratitude for the relationship the company has had with Oregon and Beaverton officials for the past 45 years, acknowledging their own excitement at the possibilities associated with future projects in the state.

"With the power of sport as a unifying force, we're committed to building more equal playing fields and to getting kids active, so they can have healthier, happier and more successful lives," they wrote. "No matter where the world takes us, Nike will always draw on the Oregon spirit in our DNA to give our best." And Beaverton officials are seemingly thrilled to be a part of the company's journey.

"The fact they chose to stay here shows the quality of Beaverton is good — and that (Nike officials) have faith in us is outstanding," Beaverton Mayor Denny Doyle told Patch on Thursday. "We're blessed they're here … it creates a culture of success and giving."

Construction is expected to begin mid-2017, with a completion date set for 2018.
