Project to add four additional floors to C Concourse to support five-star customer experience

SEATTLE – The Port of Seattle Commission today approved a final program budget of $399 million for the C Concourse Expansion project at Seattle-Tacoma International Airport (SEA). The project also released a new fly-through video with interior and exterior animations of the completed space. Once complete, the project has a goal of LEED v4 Silver certification and will be all electric and fossil-fuel free.

The project will transform the area where C and D Concourses meet by adding four floors to the building’s current three floors. The project will create one floor of office space and three floors of new public space for customer service amenities, adding new dining and retail, premium lounge space, an Interfaith Prayer and Meditation room, nursing room, and outdoor viewing area. The atrium area called the Tree at C will also feature grand seating as well as a performance area for live music.

“This is an exceptional project in terms of elevating the customer experience,” said Port of Seattle Commission President Sam Cho. “However, customer experience is not the only reason why we take on these major projects. The expanded concourse will expand opportunities for local businesses and support the financial stewardship of the airport by increasing revenue opportunities. The whole time we build with intention by focusing on sustainability and ensuring that our construction expands opportunities through the entire community.”
