Designed by Japanese firm Nikken Sekkei, and developed by Ithra Dubai, the latest addition to Dubai's skyline is a mixed-use two towers project with a horizontal connection housing one of the world's largest cantilevers. The innovative design of One Za'abeel puts in place twin skyscrapers, rising over a total built-up area of 470,700 square meters. Tower A, standing at 300 meters tall, will host offices and a hotel, the world's first vertical resort, whereas Tower B, standing at 235 meters tall, will be primarily oriented towards residential units.
