Jeddah Tower passes 100 floors in race to become tallest building

Saudi Arabia’s Jeddah Tower is on course to become the tallest building in the world after recently surpassing 100 floors and reaching a height of 400 metres. This marks a major construction milestone for the Saudi megaproject, which aims to overtake Dubai’s Burj Khalifa as the tallest structure on Earth, according to a report by Arabian Business. Located in the Red Sea city of Jeddah, the tower is planned to soar beyond 1, 000 metres, making it the first structure ever to reach the one-kilometre mark. Once finished, it will surpass Dubai’s Burj Khalifa, which currently holds the record at 828 metres, the report added. According to structural engineering firm Thornton Tomasetti, which is involved in the project’s design work, the building has officially exceeded both the 100-floor and 400-metre thresholds. The firm is collaborating with a wider team that includes Jeddah Economic Company, Langan, RWDI, Dar Al-Handasah, Saudi Binladin Group, and Turner International, while the design is led by Adrian Smith + Gordon Gill Architecture — the same architects behind the Burj Khalifa. After construction was paused in 2018, work resumed in early 2025 and has since progressed quickly. The structure advanced from roughly 80 floors in December to more than 100 floors by April 2026. Completion is currently targeted for 2028. Once finished, the development will feature a mix of hotel space, residential units, and offices, along with what is expected to be the world’s highest observation deck, forming part of the broader Jeddah Economic City project.
