Kingdom Tower will be over 1,000m tall, although no specific height has been announced for the structure.

The announcement comes just days after the UAE’s Nakheel unveiled plans for what it claims to be the world’s tallest tower.

Nakheel says its skyscraper will be more than 1 kilometre in height - although, like Kingdom Holding, it is not disclosing a final height - and will form the centrepiece of a $38bn development now known as Nakheel Harbour & Tower (MEED 06:10:08).

MEED reported in June that Nakheel had increased the height of the tower (previously called Al Burj) to 1.4km (MEED 20:06:08). Emaar's Burj Dubai is expected to reach 815 metres.

Kingdom City, located 20 kilometres from the old city of Jeddah, near King Abdulaziz International Airport, will cover an area of 7 square kilometres. It is expected to house 80,000 residents and accommodate 250,000 visitors.

The Kingdom Tower will form the centrepiece of the project. According to the company, total investment for the project will be SR100bn ($26bn).

It is the first time the designs for both projects have been revealed publicly. The unveiling took place at the international architectural exhibition being held in the city.

Some 16 projects planned for Mecca and the Jeddah region were also featured.
