WSCC Additional Facility
Projected Opening 2021

An additional WSCC facility for conventions and meetings in Seattle is on the horizon. We are currently in the early stages of developing a second, larger venue, just one block northeast of our existing facility. With this “sister” building, we expect to more than double our current capacity.

In 2017, we are continuing to secure land, refine the design, and work through the entitlements processes.  In addition, the environmental review process is under way.
