Construction is well under way on the soon-to-be-tallest building in the world: Jeddah Tower in Jeddah, Saudi Arabia, will stand at least 3,280 feet tall, and was designed by Adrian Smith + Gordon Gill Architecture of Chicago. It is part of the larger development, Jeddah Economic City, and will be the first structure in the world to reach the one-kilometer-high mark.
