Seattle Airport’s Concourse C Expansion Inspired by Nature

The Port of Seattle has released renderings for the expansion of Concourse C at Seattle-Tacoma International Airport, which is designed to celebrate the forests and landscapes of the Pacific Northwest and embrace sustainability. The project will add four floors above the existing lobby and will include 145,530 square feet of foodservice and retail, according to a Port press release.

Turner is the general contractor and Miller Hull and Woods Bagot are the architects of the project, whose budget is between 240 and 500 million dollars. The Port of Seattle Commission, which owns and operates SEA, has already approved $340 million for the work, but that amount may be increased as the project progresses, the statement said. Jacobs and Parametrix provide project management support.

Early work is expected to begin this summer, the statement said, with a major construction start in mid-2023 and project completion expected in 2027.

The project is the first to apply the new Port Sustainable project framework and is designed according to biophilic principles, depending on the version. This includes carbon reduction strategies such as fossil fuel-free systems for heating and hot water, dishwashing capabilities for suppliers to reduce the need for disposable tableware, low-flow bathroom fixtures and andelectrochromatic window glazing.

The photovoltaic and solar panels on the roofs will provide up to 15% of the energy demand of the C Concourse extension, according to the press release.

Interiors will feature corrugated Douglas fir panels on the ceiling and other wood accents, as well as observation decks with sweeping views of the Olympic Mountains and the airfield.

“The Concourse C expansion will bring much-needed light, air and passenger amenities to one of the terminal’s busiest intersections,” said Brian Court, chief designer at Miller Hull. , in a press release. “The new building was designed to bring back the excitement of flight with soaring interior volumes and multiple exterior observation decks that reconnect us to the magic of travel and the iconic mountain and sound views that define the north. -western Pacific.”

In addition to the new hall, a new $968 million international arrivals facility is slated to open at SEA this spring. It includes a large 450,000 square foot lobby with baggage claim and customs processing. A renovation is also proposed for the 40-year-old S Concourse to add retail and dining space and improve the system that transports bags to baggage claim. However, the port has yet to release a price tag or other major details about it.

The eco-friendly features and airy, nature-inspired spaces of SEA’s new Hall C reflect modern trends in airport design. The pandemic has accelerated the movement to include outdoor and green spaces where travelers can retreat, and many airport authorities are trying to save money and mitigate climate issues with energy-efficient items like glass adaptive and electrical and solar equipment.
