The Port of Seattle said this week it has hired two firms, The Miller Hull Partnership and Woods Bagot, as the joint project design leaders for the $340 million Concourse C expansion project at Seattle-Tacoma International Airport (SEA).

The 110,000-square-foot expansion is expected to be completed in 2027 and will be destination retail experience featuring an array of local shopping and dining options. Located between Concourses C and D, the project will have four additional floors of approximately 27,000 square feet each and feature natural daylight, multi-level dining and retail, new restrooms and seating.

Woods Bagot is a global firm with a world-class aviation portfolio, and Miller Hull is an internationally recognized architecture firm rooted in the Pacific Northwest that is known for sustainable design.

The Port of Seattle said it is committed advancing equity and addressing contracting disparities by increasing the participation of Women and Minority Business Enterprises (WMBE) and other disadvantaged firms in the project, with the goal of 15 percent design procurements going to WMBE.

The new expansion will feature a new stage for live music at the heart of the concourse.

The expansion along Concourse C will also be the first project to implement the Port’s new Sustainable Project Framework, targeting LEED Silver certification.
