HOK

HOK’s work across major aviation transport hubs and concourse halls pairs luminous, large-scale diagrid roof structures with fluid, organically contoured feature walls and acoustic micro-environments. This portfolio serves as a precise reference when balancing the monumental structural rhythm of high-throughput transit spaces with human-scale acoustic zoning, integrated wayfinding, and sculpted material surfaces.

Exterior dusk view of an airport terminal featuring a massive curved steel diagrid canopy over a multi-lane roadway.

Aviation + Transportation

A large-scale transportation terminal precedent showcasing a sweeping structural steel diagrid canopy that defines the arrival and drop-off zone at dusk.

What we like about this project
The massive scale of the diagrid roof appears lightweight and glowing against the evening sky due to integrated canopy lighting.

Geometry
An expansive arching diagrid roof shell spans over the terminal drop-off lanes, creating a dynamic double-curved volumetric envelope.
Facade system
Glazed terminal facade sheltered beneath an independent exterior structural steel space frame and canopy.
Structural guess
Complex spatial steel diagrid truss system supported by heavy concrete columns and foundations.
Spatial scale
Massive civic scale; the overarching canopy spans across multiple roadway lanes and several stories in height.
Lighting
Twilight sky with warm sunset glow on the horizon contrasting against the cool internal illumination of the canopy diagrid structure.
Atmosphere
Dynamic and luminous, blending the motion of transit with a grand sculptural roofscape.
Environmental context
Transportation hub drop-off zone with multi-lane vehicular roadways and traffic light trails.
Spatial experience
The sweeping curve of the roof and overhead canopy frames the arrival sequence, guiding vehicular and pedestrian movement toward the terminal entrance beneath a luminous framework.
Composition rhythm
Sweeping longitudinal curves intersected by a dense, repeating structural diagrid mesh.
