The Nike Worldwide Headquarters sits southwest of Portland in what is now the business-heavy city of Beaverton, Ore. Impressive in its own right, the Nike campus will only get more daunting, starting with Thursday’s expansion kick off.

Included in the evolution of Oregon’s largest business and the world’s largest athletic apparel and shoe maker will be two new office buildings, one designed by Skylab Architecture and the other by ZGF Architects, a new fitness facility and two new parking structures.

The building designed by Skylab will rise nine stories and offer 887,000 sq ft on the north side of the Nike campus. The other building, 412,000 sq ft west of the Skylab design, will have a ZGF touch to it.

The addition of two high-reaching buildings will bolster Nike’s 2.2 million sq ft of space on the Beaverton land by about a third—the expansion is about 1.3 million sq ft—and keep temporary construction jobs in Washington County.

Nike has often used a mix of architects on different structures, whether at its Beaverton headquarters or in Phil Knight-funded projects on the University of Oregon campus in Eugene, Oregon. ZGF’s Eugene Sandoval was instrumental in some of the more forward-looking designs to hit the Ducks’ campus.

With Nike traditionally tight lipped about future plans, the design of the two new buildings doesn’t offer a retreat from the norm in terms of information. But do expect some Skylab signatures, with a design that protrudes over a campus street, over 200,00 sq ft of “accessory space” and a history of Skylab’s funky design of the Hoke Residence that hit the big screen in Twilight.

"Our expansion efforts are designed to provide Nike employees and teams with a work environment that inspires creativity and collaboration, and experiences and services that can support Nike's workforce of the future," the company said in a statement.

The $150 million-plus project does not have a construction timeline made public.
