Saudi Arabia’s landmark Jeddah Tower has reached a significant point in its development, surpassing 80 floors in 2025, according to project engineers. This progress signals renewed momentum for one of the world’s most ambitious architectural undertakings.
When finished, the tower is projected to rise beyond 1,000 meters, making it the first man-made structure to achieve a full kilometre in height. This feat will cement Jeddah Tower’s position as a global icon of engineering and urban design.
The structural design is being led by U.S.-based consultancy Thornton Tomasetti, which confirmed the milestone. The firm is collaborating with Adrian Smith + Gordon Gill Architecture, the design architect, to create advanced structural solutions tailored to the tower’s unprecedented scale.
The project involves a multidisciplinary team, including Langan Engineering & Environmental Services, RWDI, Dar, and the main contractor, Saudi Binladin Group. Together, they are implementing cutting-edge systems and materials to meet the challenges posed by extreme height, wind loads, vertical transportation, and long-term durability.
Conceived as a mixed-use “vertical city,” Jeddah Tower will integrate residential units, hotel accommodations, commercial spaces, and observation decks. Its complexity demands innovative engineering approaches to ensure performance and resilience.
Reaching the 80-floor threshold marks a pivotal stage in the tower’s upward journey. As construction advances, Jeddah Tower is poised to redefine global standards for supertall buildings and urban ambition.
