The campus is just off the interchange between Interstate 405 and Washington State Route 520, which connect the area to downtown Seattle, 10 miles west.

The coworking sector continues its expansion beyond gateway cities and into secondary and tertiary markets, making flex offices accessible to remote teams. Providers have turned their attention towards these smaller markets because they allow for larger spaces in Class B and older office properties. As of April, there were 9,200 coworking locations across the U.S., amounting to 165 million square feet, CoworkingCafe data shows. This accounted for 2.3 percent of the national office inventory.
