Developers are unveiling the world's biggest ever construction projects at the four-day Dubai property event

Developers Nakheel, Emaar and Limitless are among the big developers showing off their new megaprojects at Cityscape Dubai, which opened today.

The four day event, the largest of its kind in the world, is expected to attract over 60,000 visitors from 150 countries around the world.

Alongside the kilometre-high skyscrapers and reclaimed islands will be a new focus on sustainability, if developers are to be believed.

Building’s Roxane McMeeken and Phil Clark will be sending in regular updates from the Desert City.
