Kingdom Holding Company (KHC) has selected Calthrope Associates as the lead master planner of Kingdom City Jeddah project, a 5.3 million m² mixed-use development to the north of Jeddah, Saudi Arabia.
Godwin Austen Johnson (GAJ) has been selected as urban architect for the project.
The mixed-use development includes the $1.2bn Kingdom Tower, which will be over 1km in height and spread across an area of 530,000m².
Designed by US-based Adrian Smith + Gordon Gill Architecture, the 161-storey tower forms the first phase of the development and features a hotel, apartments, offices, three lobbies on the upper floors and an observation deck on the 157th floor.
Kingdom Tower will also accommodate a high-end shopping mall, additional development parcels that will house commercial and high-density residential buildings and open spaces, including the central tower plaza.
The tower will contain 59 elevators, including 54 single-deck and five double-deck elevators, along with 12 escalators.
Sustainable features of the tower include a high-performance exterior wall system to minimise energy consumption by reducing thermal loads, while three sides of the building will feature a series of notches that create pockets of shadow, shielding parts of the building from the sun.
After its completion in 2018, the tower is expected to be the tallest in the world, 173m taller than the current tallest building, the 828m Burj Khalifa in Dubai.
The entire Kingdom City Jeddah project is expected to cost SR75bn ($20bn) and take ten years to complete.
