New plan to construct world's tallest building

The Burj Khalifa, the tallest building in both Dubai and the world, may not be holding its title for much longer. Developers recently announced plans to build a skyscraper in the city that will stretch higher than the current record-holder by 'a notch.'

The tower, designed by architect Santiago Calatrava Valls, is envisioned as a tall, slim structure that will mimic the appearance of a minaret. It will be tethered to the ground by a network of leaf-like cables. Features include observation decks, restaurants, a boutique hotel, and private residences.

The goal is to have the building completed by 2020, the year the world Expo trading fair is to be held in Dubai.
