The Saudi Arabian government reveals plans to build a 400-metre-high cube-shaped skyscraper named Mukaab as part of its Murabba downtown plan in Riyadh, Invest-Gate reports.

Set to be built to the northwest of central Riyadh, the 19-square-kilometre development is being planned as a new downtown area for the Saudi capital city.

Described as the “new face of Riyadh”, it will be built around the Mukaab structure, which will be “one of the largest built structures in the world”.

The structure will be 400 metres high, making it officially a supertall skyscraper, and 400 metres long on each side. It will become the tallest building in the city.

In addition, the cube-shaped building will be enclosed in a facade made of overlapping triangular forms that was informed by the modern Najdi architectural style.

It will contain two mn sqm of shops, cultural and tourist attractions and have an almost full-height atrium space that will contain a spiralling tower.

Further, the wider development will contain over 100,000 residential units and 9,000 hotel rooms along with more than 980,000 sqm of shops and 1.4 million sqm of office space.

It will also include 80 entertainment and culture venues, technology and design university, a multipurpose immersive theatre and an “iconic” museum.

The whole project is scheduled to be completed by 2030.

It is worth noting that the new project aims to support the Saudi economy with $48bn, and create 334,000 direct and indirect vacancies.
