The "crown jewel" 500-acre Burj Khalifa development, incorporating hotel, residential, retail and office spaces, is located in the heart of downtown Dubai.

At 828 meters, Burj Khalifa is the tallest building in the world. The 162-story tower has 185,000 square meters of residential space (1,000+ apartments) and more than 28,000 square meters (49 floors) of office space. Additionally, the tower contains a 160-room Armani Hotel with the world’s highest swimming pool, located on the 76th floor. The Burj Khalifa also boasts the world’s highest outdoor observation deck on the 124th floor.

At the peak of construction, more than 12,000 people from over 100 countries were working on site. In total, Burj Khalifa required 22 million people hours in order to achieve completion in January 2010.
