As WAN has suggested over the past few months, supertall building experts Adrian Smith + Gordon Gill are to complete the design for a stunning new tower to anchor the proposed $20bn Kingdom City masterplanning project in Jeddah, Saudi Arabia. The firm carefully quashed internet rumours that they were working on a 'mile-high' tower, yet did not deny involvement in the Kingdom Tower scheme. This morning His Royal Highness Prince Alwaleed Bin Talal Bin Abdulaziz Alsaud, nephew of Saudi Arabia’s King Abdullah and chairman of Kingdom Holding Company officially announced AS+GG as design architects of the project to awaiting media.
