with an undulating lattice facade, zaha hadid architects' metro station opens in riyadh

a sculptural landmark to enhance mobility in riyadh

The King Abdullah Financial District (KAFD) Metro Station, designed by Zaha Hadid Architects (ZHA), is a sculptural centerpiece of the ambitious Riyadh Metro network set to open its first lines on December 1, 2024. Located in Saudi Arabia’s capital, this state-of-the-art station with its undulating lattice facade plays a key role in the world’s longest driverless transit system, spanning 176 kilometers across six lines and 85 stations.

The Riyadh Metro network is a major urban initiative by the Royal Commission for Riyadh City (RCRC), designed to alleviate traffic congestion and improve the quality of life for the city’s growing population. With a daily capacity of 3.6 million passengers, the system will reduce car dependency and promote sustainable transportation. The opening of the Blue, Yellow, and Purple lines will connect key districts, business centers, and cultural landmarks across the city.

The team at Zaha Hadid Architects completes the KAFD Metro Station, bringing a vital interchange for the city’s network. The hub connects rail services with bus routes and park-and-ride facilities. Strategically located in the King Abdullah Financial District, it links the district’s terminus to King Khalid International Airport and provides direct access to the KAFD monorail skybridge. The design incorporates both indoor and outdoor plazas, creating vibrant public spaces for the area.

Connectivity is a core principle of ZHA’s design. The station’s configuration is based on predictive modeling of rail, car, and pedestrian traffic flows, resulting in a layout optimized to minimize congestion and maximize efficiency. An undulating three-dimensional lattice structure, inspired by opposing sinewaves, organizes the building’s circulation while shaping its architectural identity.

The Riyadh Metro Station’s exterior is clad in ultra-high-performance concrete panels, which Zaha Hadid Architects designs with geometric perforations to reduce solar gain. This facade, a reinterpretation of traditional regional architecture, echoes the natural patterns formed by desert winds. The design balances aesthetic impact with practical environmental benefits, offering both shelter and sustainability.

ZHA optimized the station’s design to enhance structural efficiency and environmental performance while simplifying the construction process. The station’s external envelope integrates with its internal structure, supporting both the train platforms and viaducts. Sliding door panels on platforms retain cool air, while a high-efficiency cooling system, powered by renewable energy, adjusts to passenger levels throughout the day. These features have earned the station LEED Gold certification.
