Project Porten, Stockholm Arlanda Airport

An airport is, in many ways, its own universe. A threshold filled with anticipation. Special transportation brings you there, and perhaps your to-do list includes buying sunscreen or grabbing a pre-flight beer. Stockholm Arlanda Airport is no exception.

Navigating with precision

We carefully analyzed all the functions and interests present at the site. Passenger flows, security, and shopping impose diverse spatial requirements. Calling Project Porten both an architectural and logistical challenge is no exaggeration.

Our design approach focused on creating a functional yet aesthetically appealing framework that unifies various areas. We also sought to harmonize with the existing buildings, each reflecting the era of its construction.

Arlanda aims to inspire commerce and connection. Travelers should feel welcomed and inclined to spend time here. Clean, distinct, and curved forms paired with carefully chosen materials convey reliability, warmth, and hospitality.

“In designing the security checkpoint and marketplace, we employed a cohesive palette of white and gray tones, metal, glass, wood, and concrete. Transparency and outward views became integral design features,” says Rebecca Andersson, architect at Tengbom and Project Manager for Arlanda.

Bold yet respectful

Tengbom’s most visible contribution to Terminal 5 is a 330-meter-long extension that houses the security checkpoint alongside retail and dining areas. The new building—a closed rectangular volume—is situated in front of the entrance hall, with its geometric character carried over into the new facade. Dynamic variations are created through light and shadow play on the facade’s panels.

“The main functions—security and marketplace—require facades without windows for security reasons. Daylight, however, was crucial, making this a challenge, but we achieved a great result. The facade exudes an intriguing sense of closure,” Rebecca Andersson explains.

Forms inspired by aviation

“Our goal was to give the facade an aircraft aesthetic—a material and shape reminiscent of airplane wings,” Rebecca explains. The curved aluminum panels are perforated underneath, creating a contrast with the smooth, curved upper surfaces.

Timeless interiors and high security

Inside, the design employs neutral, warm tones referencing past eras, such as birch panels and limestone floors from the airport’s oldest building, constructed in 1976. A continuous, transparent metallic ceiling conveys airiness and lightness. Horizontal elements—typical in airports—are prominent here as well. The result? A timeless design built to endure.

The two previous security checkpoints in Terminal 5 have been consolidated into one modern facility. Key considerations included effective lighting, clear flows, and high navigability. Durable and timeless materials imbue the space with a distinctly Scandinavian character. Architectural elements like columns, floors, and ceilings establish order and rhythm.

“To accommodate future operations and changing needs, flexibility was crucial. The new sections are essentially a platform built for future transformations.”

Smart processes for holistic success

Project Porten was complex, requiring clarity in the underlying processes. Collaboration was the golden thread throughout. Adapting to new security standards and other changes demanded robust and communicable concepts.

“Our goal was to find rational architecture that meets stringent functional and security demands while making Arlanda a vibrant 24/7 destination,” Rebecca concludes. “The renovation aimed to enhance travelers’ experiences and provide the best possible start to their journey. The additions strengthen the overall impression for travelers and those who work at or pass through the airport.”
