OUALALOU+CHOI Wins Competition for Casablanca’s Casa Sud Station

OUALALOU+CHOI has won the international competition to design Casa Sud Train Station, a project that connects Casablanca’s infrastructure with the surrounding city. Designed as both civic space and architectural statement, the new station is imagined as a connective threshold — one that bridges past and present, movement and pause, infrastructure and landscape.

Located at the southern edge of Casablanca, the project occupies a pivotal site between the city’s historic centre and its expanding modern districts. Here, the architects propose a structure that links the divided neighbourhoods across the railway lines, knitting the urban fabric together.

At its core, the design is defined by a monumental vaulted roof, a single unifying gesture that gathers all the station’s functions beneath one continuous form. The roof’s spherical geometry lends the project a spatial balance — a structure that gives equal importance to every direction and every surrounding neighbourhood. Beneath this immense canopy, circulation, light, and activity unfold in what OUALALOU+CHOI describe as a “functional and poetic choreography”, transforming the act of travel into an experience of architectural movement.

The station’s edges are conceived as porous and open, allowing the building to merge with the life of the city. Transparent façades dissolve boundaries, while at its base, a new urban park extends the public realm and introduces much-needed greenery to Casablanca’s dense urban texture.

Crowning the structure, a 360-degree belvedere offers sweeping views across the metropolis, making the station a destination in itself. The gesture reinforces the project’s dual nature — infrastructural and symbolic, grounded and elevated — while embedding it in Casablanca’s skyline as a new urban reference.

Casa Sud reflects OUALALOU+CHOI’s approach to architecture as an act of connection. The station proposes a modern agora — a shared space where civic life, landscape, and architecture converge. Scheduled for completion in 2029, Casa Sud stands poised to become a defining landmark for the city.
