New images of Santiago Calatrava‘s Dubai Creek Tower have emerged, showing construction progress on what is expected to become the world’s tallest building. Developer Emaar Properties released site photos and video of the 2.3 square-mile complex, which is designed to eclipse the height of the Burj Khalifa by at least 300 feet.

Emaar Properties and Dubai Holdings joined together to build the new complex in Dubai, which will feature a 3,045-foot tower designed by Calatrava as its centerpiece. The tower requires laying record-breaking 236-foot deep foundation piles capped with 1.59 million cubic feet of concrete.

The tower, inspired by the lily flower and mosque minarets, will feature a 68-mile array of supporting cables, a 360-degree observation deck and a Hanging Gardens of Babylon-style floor. It broke ground last year, but the developer still hasn’t confirmed the completion date. According to previous reports, the project is expected to be ready in time for Dubai Expo 2020.
