Saudi Arabia builds world's largest building, El Mukaab, challenging engineering limits

Saudi Arabia is undertaking an ambitious engineering feat with the construction of El Mukaab in Riyadh, designed to be the world's largest building by volume. Standing at 400 meters high, 400 meters wide, and 400 meters long, this colossal cube is the centerpiece of the New Murabba development, set to redefine the Saudi skyline. Its interior space is so vast it could accommodate 20 buildings the size of New York's Empire State Building, establishing a new benchmark for massive-scale architecture.

The cube's exterior design draws inspiration from traditional Najdi architecture, blending geometric patterns with futuristic technology. Spearheaded by Crown Prince Mohammed bin Salman as part of the Vision 2030 plan, the project aims to diversify Saudi Arabia's economy away from oil by establishing a global tourism and commercial center. The complex will feature a central spiral tower with advanced holographic technology capable of projecting immersive scenarios, allowing visitors to experience diverse environments, such as "sleeping in the Serengeti and waking up in New York."

Logistically, the project demanded unprecedented measures, including the excavation of nearly ten million cubic meters of earth, equivalent to about 4,000 Olympic swimming pools. To manage the heavy machinery traffic without disrupting Riyadh's infrastructure, a temporary bridge was built over King Khalid Highway. Despite the grand vision, the project has encountered financial challenges. While initially planned for significant infrastructure completion by 2030, reports indicate temporary construction suspensions in early 2026. This pause is attributed to a strategic reassessment by the Saudi sovereign wealth fund, which is prioritizing investments with shorter-term economic returns and urgent projects like infrastructure for Expo 2030 and the 2034 World Cup.
