Kingdom City, designed by Adrian Smith and Gordon Gill Architecture (AS+GG), recycles the Burj’s planning formula down to the surrounding moat and towers – only bigger. The buildings encircling the Kingdom Tower will rise from 20 storeys (for those nearest) to 60 storeys, so everyone in them should get a good view. Smith says they expect 3 million visitors a year – some delivered by the planned new metro system, the stations of which Norman Foster’s practice is tipped to design.
