The King Abdullah Financial District Metro Station, designed by Zaha Hadid Architects, will serve as a key interchange on the new Riyadh Metro network, in Saudi Arabia. The configuration is a three-dimensional lattice defined by a sequence of opposing sine-waves which act as the spine for the building’s circulation. Responding to the functional requirements of a multimodal transport center and the district’s future vision, the project extends beyond the simple station typology to emphasize the building’s importance as a dynamic, multi-functional public space in view of Expo 2030.
