Burj Khalifa in Dubai is the world's tallest building. The structure reaches a height of over 800 metres. It was designed by an American company and built at a cost of over 1.5 billion dollars. Over 12,000 men and women worked on the building during the peak of construction.

The skyscraper does not have a steel frame but a concrete structure. Thousands of glass panels give it a futuristic appearance.

Burj Khalifa is a multi-use building. It contains apartments, hotels, restaurants and sky lobbies.
