The Jeddah Tower in Saudi Arabia is under construction and designed to exceed 1,000 meters, which would make it the first building to reach 1 kilometer in height.

Formerly known as Kingdom Tower, the Jeddah Tower resumed construction in January 2025 after several years of delays. Designed by Adrian Smith + Gordon Gill Architecture, it is planned to reach over 1,000 meters with approximately 157 floors. When completed, it will surpass the Burj Khalifa by roughly 200 meters and claim the title of world's tallest building. The tower will include the world's highest observation deck at over 500 meters.
