Largest airport passenger terminal building

The Hong Kong International Airport passenger terminal building is 1.3 km (0.8 miles) long and covers 550,000 m² (5,920,150 ft²). The building's design incorporates a Y-shaped concourse and is the world's largest single airport building. Just the baggage hall of this gargantuan building is as big as the Yankee Stadium in New York (it could hold five Boeing 747s parked wing tip to wing tip). Served by 48 aircraft parking stands with boarding gates and air bridges, the terminal has a design capacity of 45 million passengers a year, arriving on 460 flights every day. There are three kilometers (1.8 miles) of moving walkways, 55,000 m² (592,000 ft²) of glass cladding and around 117,000 m² (1,259,400 ft²) of carpeting. The terminal is one of the largest covered public spaces ever created, but the platform on which it is built is nearly as impressive. In 1992 Chek Lap Kok was a 100m high mountain island off the south coast of China. Today, at 6km (3.7 miles) long and 3.5km (2.1 miles) wide, it has been stretched to four times its original size and flattened to a uniform 7m (23ft) above sea level. Remarkably, the entire project airport project was completed in five years.
