The Al Dar Headquarters is designed to be an architectural icon that shines as the center of the Al Raha Beach Development in Abu Dhabi. The work of MZ Architects, it is inspired by the clam shell, which has deep cultural meaning for the local seafaring heritage. The 110 meter high circular skyscraper has an area of four football fields. Unlike conventional four-sided structures, this three-faceted building has a zipper-like element that stitches the two main facets together. A complex external diamond-shaped steel structure, called a diagrid, was developed to support the building's 25 meters of cantilever. The main facades used a toroidal geometry cut by a cylinder to create the perfect circle, and used ten panels instead of 10,000 typically needed for the refined geometry. From afar, Al Dar Headquarters begins as a shiny dot that rises from the water, then expands to become a giant mirror of the world.
