Saudi Arabia’s new record-breaking 1,000 metre plus Kingdom Tower is a step closer to realisation, the developers announcing the project has gained financing.

Billionaire prince Alwaleed bin Talal, who heads investment firm Kingdom Holding Co, said it signed a $1 billion deal with the Saudi Binladen Group to build the tower

Designed by Adrian Smith + Gordon Gill Architecture, it will be the centrepiece and first construction phase of the Kingdom City development on the outskirts of the Red Sea city of Jeddah.

The tower's height will be at least 173 meters (568 feet) taller than the world's current tallest building, Dubai's 828-meter-tall Burj Khalifa, which was designed by Adrian Smith while at Skidmore, Owings & Merrill.

The tower would rise above today’s highest skyscraper, the 828-metre Burj Khalifa in Dubai, when completed.
