Scorching on the heels of the completion of SOM’s practically $1 billion Worldwide Arrivals Facility (IAF) at Seattle-Tacoma Worldwide Airport, hometown agency Miller Hull Partnership and Woods Bagot have revealed their design for the subsequent main capital venture on the busy West Coast aviation hub: an amenity-heavy, 145,500-square-foot enlargement spanning the airport’s present C and D concourses.
In a press release, Matt Ducharme, a principal on the Adelaide, Australia-founded Woods Bagot who serves as the worldwide agency’s West Coast Design Chief, described the expanded C Concourse at Sea-Tac’s principal terminal as being “an inspiring gathering place that could be a vacation spot in and of itself. This bold venture intertwines the perfect features of placemaking, sustainability, and signature structure.”
Set to be accomplished in 2027 with main building work kicking off in mid-2023, the Port of Seattle’s $340 million C Concourse enlargement at Sea-Tac can be anchored by a hovering public house dubbed the Grand Stairs the place passengers will discover open, amphitheater-style seating and a bustling, marketplace-inspired space “designed to mirror the textures and actions of the well-known markets in Seattle and the area,” in accordance with a press launch revealing preliminary design renderings and particulars. Authenticity is essential right here and, as such, an space for buskers will be part of the assemblage of retail and meals stalls on the middle of the newly expanded concourse. Atop the Grand Stairs can be a mezzanine degree that may function further eateries and outlets together with a sequence of balconies the place vacationers can pause to look out onto Sea-Tac’s airfield (with glimpses of the area’s dramatic pure magnificence past) by way of huge home windows that may flood the inside with pure gentle.
Additionally included within the enlargement can be a brand new 20,000-square-foot Alaska Airways Lounge, interfaith prayer room, meditation room, nursing suite, and workplace house for the TSA, airways, and airport companies.
As detailed by Miller Hull and Woods Bagot, the design of the brand new constructing was impressed by the idea of “bringing in, seeing out” in that it “welcomes within the surrounding context and connects again to the regional panorama.”
“The C Concourse Growth will carry much-needed gentle, air, and passenger facilities to one of many busiest crossroads within the terminal,” mentioned Brian Court docket, lead designer and associate at Miller Hull. “The brand new constructing was designed to carry again the joy of flight with hovering inside volumes of house and a number of outside commentary decks that reconnect us to the magic of journey and the long-lasting mountain and sound views that outline the Pacific Northwest.”
With a purpose to try this, “the constructing’s first key function is a performative exterior envelope impressed by the forest and the body,” elaborated each corporations. “Simply as in nature, the place the forest protects from the solar, the constructing’s shell modulates gentle and collects power.”
A deal with evoking—and incorporating—the rugged pure panorama of the Pacific Northwest, one dominated by hovering mountains, dense forests, mighty rivers, and an enormous inland sea, isn’t dissimilar to the method taken by ZGF Architects for its timber-topped new principal terminal constructing at Portland Worldwide Airport. Miller Hull and Woods Bagot’s Sea-Tac enlargement additionally showcases domestically sourced wooden together with its Douglas fir coffered ceiling and “focal pillar” on the Grand Stairs.
Along with establishing a direct connection between the brand new constructing and the pure panorama, the venture additionally locations an outsized emphasis on sustainability. It’s the first at Sea-Tac to make use of the Port of Seattle’s new Sustainable Challenge Framework and, as such, “units the precedent for all future capital initiatives.” Key sustainability parts are set to incorporate, amongst others, a rooftop photo voltaic array projected to offer the concourse with 15 % of its power demand, electrochromic glazing for home windows, fossil-fuel-free heating and sizzling water techniques, low-flow water fixtures, embodied carbon discount methods, and the incorporation of biophilic design rules that may “create a connection to the outside with pure lighting, panorama options and different parts for a way of well-being for vacationers,” in accordance with the Port of Seattle.
The not too long ago unveiled IAF terminal, an intensive revamp of the ageing North Satellite tv for pc Terminal designed by Fentress Architects and AECOM that absolutely debuted final summer season, and, now, the C Concourse enlargement set to kick off within the coming months, are simply three notable undertakings in a string of capital initiatives at Sea-Tac that may allow the airport, the nation’s ninth-busiest by passenger quantity, to accommodate record-setting passenger development.
Though these renovations, expansions, and different initiatives make for a extra environment friendly and cozy hub, important future development is restricted on condition that Sea-Tac is bodily constrained by its comparatively small footprint for an airport of its stature. Encircled by residential and business growth throughout the metropolis of SeaTac, the airport, at about 2,500 acres, is the smallest main worldwide airport in america by land dimension (by comparability, Denver and Dallas/Fort Price are the most important) and has restricted room to broaden outwards or be additional reconfigured—there’s simply not sufficient to work with. Because of this, state officers are within the early phases of figuring out potential websites for a second main business airport serving the Puget Sound area that will complement Sea-Tac. Regardless of its small dimension, one aspect of Sea-Tac is positively huge: its iconic Brutalist parking construction, which ranks because the second-largest under-one-roof car parking zone on the earth.
