New Standard for Sustainable Travel: The C Concourse Expansion at SEA Airport
The C Concourse’s expanded facility at Seattle-Tacoma International Airport (SEA) will be the airport's greenest building yet, not only creating a better travel experience but also setting a new standard for climate-conscious design and construction. SEA is working with design partners Miller Hull and Woods Bagot, to renovate this concourse to integrate everything from all-electric systems and water conservation methods to biophilic design — a testament to our commitment to a greener future. You've probably seen the crane and construction activity, but we're excited to show you that behind the barricades, a truly sustainable building is taking shape.
