Dubai set to build another tower higher than Burj Khalifa

Dubai is set to build a tower higher than the existing record-braaking skyscraper, the Burj Khalifa, which is presently the world's tallest building. Construction for the new tower which is to be known as The Tower at Dubai Creek, will start at the end of June this year and is hoped to be finished before Dubai hosts the World Expo in 2020. The tower is said to cost around $1 billion and will be a notch taller than Burj Khalifa which opened in January 2010 and stands at 828 meters high.
