The tower, designed by Spanish-Swiss neo-futuristic architect Santiago Calatrava Valls, is slated to have a rooftop courtyard, residential units and a link to a retail plaza.
The building is expected to be completed for the Dubai Expo trade fair in 2020, the same year that the kilometre-high Kingdom Tower in Jeddah is due to overtake the Burj Khalifa as the world's tallest building.
Funding for the US$1 billion (NZ$1.46 billion) project will be 50 per cent equity and 50 perc ent debt, Alabbar said, undeterred by a residential property market that consultancy Cluttons says has softened for at at least five quarters.
The balance between supply and demand is very encouraging, Alabbar said. He declined to give figures, but said: "I don't see a pullback. We are doing better than 2015."
