Qasr AlHokm Metro Station introduces large-scale public transport infrastructure into the historic center of Riyadh through a spatial framework that combines an underground transit interchange with a civic plaza. Organized around a reflective canopy and a deep atrium, the station links two lines of the city’s expanding metro network while establishing a new public surface within the Al‑Qiri district. The project approaches the metro station not as a purely infrastructural object but as an urban room that connects transportation, landscape, and civic gathering space.

When you come off the train and look up, you see a 360-degree view of the city reflected on the underside of the canopy. You immediately understand where you are in relation to the city, while the same surface mirrors the activity unfolding below.

Urban Catalyst in Riyadh’s Historic Core
The station is located in the Al‑Qiri district near several important historical landmarks, including the early palace complex and surrounding adobe neighborhoods. Its position places contemporary transport infrastructure within a dense cultural landscape that retains significant historical memory. The site also borders a large Eid prayer field, an expansive urban space that periodically accommodates major religious gatherings. Instead of isolating the metro entrance as a technical fragment within the city, the project situates it within a civic field that must function at multiple social scales.
A continuous terrazzo surface organizes this condition into a legible urban ground plane. The plaza extends across the entire site, integrating the metro access points, pedestrian circulation, and a reconstructed neighborhood mosque. The smooth, uninterrupted surface allows the space to transition from everyday pedestrian use to large gatherings during religious events. Subtle linear drainage channels oriented toward Makkah further reinforce the relationship between the plaza and the mosque, allowing the open ground to operate as an exterior extension of the religious complex.
This approach reframes the metro station as part of a broader civic landscape rather than a singular object. In a city long shaped by automobile circulation, the plaza introduces a pedestrian territory designed for pause, gathering, and collective movement. The station becomes both transit infrastructure and urban square, embedding public transport within a spatial structure that supports shared urban life.
The Reflective Canopy as Urban Instrument
The plaza is anchored by a large stainless-steel canopy that defines the station’s primary presence above ground. Its double-curved geometry forms a broad hovering disc that extends beyond the circular base of the station’s structural cone. The canopy shelters a large portion of the public space from direct solar exposure, an essential environmental response in the desert climate. The overhang establishes a shaded zone that encourages lingering while clearly marking the principal entrance.
The underside of the canopy operates as a continuous mirror. Polished stainless-steel panels reflect the surrounding city, the landscape of the plaza, and the activity within the atrium below. This reflective surface establishes a visual relationship between street level and the subterranean spaces of the station. It also redirects indirect daylight toward the central opening, allowing light to penetrate deep into the underground volumes.
The canopy is supported by a steel spaceframe structure connected to the reflective skin through adjustable tie rods. This system allows the structure to project outward with minimal visible support, giving the appearance of a suspended surface hovering above the plaza. Photovoltaic panels are mounted on the upper portion of the canopy roof, integrating energy generation while maintaining the uninterrupted reflective quality of the underside.
Vertical Spatial Organization and Legible Infrastructure
Beneath the plaza, the station descends through eight underground levels organized around a central cone-shaped atrium. This large void provides visual continuity from ground level to the lowest circulation areas, giving passengers a constant sense of orientation. The concave form of the rendered interior walls reinforces this spatial focus, directing visual attention upward toward the reflective canopy and downward toward the deeper parts of the station.
The metro platforms are housed within glass‑encased tubes that extend into the open atrium. These transparent enclosures reveal the movement of trains and passengers while protecting the platforms. Their visibility transforms typically concealed transit infrastructure into a readable component of the interior space. Passengers approaching the station can immediately identify platform locations through the presence of these illuminated volumes.
Circulation unfolds along a sequence of escalators and walkways that trace the cone’s perimeter. Each level maintains visual connections to the others, producing an environment in which navigation relies less on signage and more on spatial legibility. The visibility of movement across multiple levels produces a dynamic interior section, where the daily choreography of urban mobility becomes part of the architectural experience.
Material Expression, Light, and Cultural Referencing
The interior cone wall introduces a patterned surface derived from traditional Najdi architecture. A series of triangular carvings punctures the rendered walls, creating 326 openings in three different scales. These voids filter light between levels while establishing a link to geometric motifs present in the surrounding historic neighborhoods. The pattern also produces brief visual connections between circulation paths, allowing fragments of movement and light to appear through the carved openings.
Behind the cone wall, a continuous media installation runs along the interior liner wall. Composed of hundreds of acoustic, lighting, and video panels, this elongated surface introduces calibrated illumination within the large atrium. The shifting patterns of light articulate the scale of the concourse and support orientation within the station’s complex vertical volume. Rather than functioning solely as visual spectacle, the illuminated wall helps define the spatial edges of circulation areas.
At the lowest point of the atrium, approximately thirty‑five meters below ground, a landscaped garden provides a contrasting spatial atmosphere to the station’s infrastructural spaces. Planting beds and living walls form a shaded pathway that passengers encounter while transferring between lines. Daylight filters through the atrium opening above, supplemented by artificial lighting that maintains an even environmental tone. Irrigation water is collected from the canopy and plaza surfaces above, sustaining a temperate garden environment that offers a moment of calm within the dense movement of the transport hub.
About Snohetta
Snohetta is a transdisciplinary architecture and design practice based in Oslo, Norway, founded by Kjetil Traedal Thorsen and Craig Dykers. The studio works across architecture, landscape architecture, interior architecture, product design, graphic design, and digital design, approaching projects through an integrated design methodology that links buildings, landscapes, infrastructure, and public space. Known internationally for projects such as the Bibliotheca Alexandrina in Egypt, the Norwegian National Opera and Ballet in Oslo, and the expansion of the San Francisco Museum of Modern Art (SFMOMA), the practice operates globally from offices including Oslo, New York, Paris, Innsbruck, Hong Kong, Adelaide, and San Francisco.
