Born in Riyadh, Ahmed Alhatti is the man behind the $272mn “twisting tower” called Cayan Tower, in Dubai Marina. The 75-storey skyscraper was delivered after seven years last June following a series of delays. It has since gone on to win plaudits and awards for its original design, which reduces wind forces on the tower. Alhatti told CW in February that he was assessing land options for more projects in Dubai. “I am taking my time in the UAE, because everyone is waiting to see what we will do after Cayan Tower. We want to do something unique; we can’t just do a normal building anymore.”
