Capital Gate, also known as the Leaning Tower of Abu Dhabi, is a skyscraper with a striking lean. Inclined by 18° to the west, this spectacular high-rise was made possible by a diagrid structure. The iconic building even received an entry into the Guinness World Records as the “world’s furthest leaning man-made tower”. This book tells the story behind the design by architectural office RMJM and explains the sophisticated structural concept.
