French architecture firm Valode & Pistre is set to break ground on Africa's $1bn tower, the tallest in Casablanca, Morocco, in June 2015.
Middle East Development in Dubai will commence work on the new Al Noor Tower, which is said to be a mixed-use tower rising to a height of 540m.
The skyscraper is claimed to be more than double the height of Johannesburg's 223m Carlton Center, which was completed in 1973, and will be built on a 25ha site in the Moroccan city of Casablanca.
Comprising a total floorspace of 335,000m², the tower will house a 200-room luxury hotel, a trading platform, conference hall and art gallery, as well as a 100m-tall atrium that hollows the base of the skyscraper.
Al Noor Tower's facade has been designed as a pixilated representation of Africa's 1,000 languages. Its 114 floors are said to honour the same number of chapters in the Quran.
The 540m height of the building represents the total number of African countries.
The tower is part of a larger project by UAE-based Middle East Development. It is expected to cost $1bn and be completed in 2018.
