The number of Chinese tourists eager to travel the world has risen dramatically over the last few years, and Beijing International Airport is launching the world's biggest terminal to cope with the substantial increase. Opening in 2018, the gigantic Terminal 1 will cover 700,000 square metres, and is set to handle 45million passengers a year. Renown British-Iraqi architect, Zaha Hadid, has collaborated with airport developers ADPI to create a six-tier concept which aims to decrease customer walking distances, and increase connectivity.

Aiming to be the perfect welcome to Beijing, the designs focus on creating a feeling of space and openness, which is reflected in the flowing lines of the roof, and the lack of pillars inside. All the passenger pathways will convene in a central multi-layered courtyard, which will be a meeting place for passengers who have travelled from around the globe. Zaha Hadid's website states that the structure of Terminal 1 will guide users seamlessly and harmoniously through the building by public spaces that flow into each other, reflecting the harmony and balance between Chinese landscape and culture. It is hoped to combine the rich Chinese culture, with its impressive future on the worldwide stage. The huge terminal will focus on wide open spaces, made possible by the lack of pillars and flowing roof design . The international airport, which also goes by the name of Daxing Airport, is the second busiest in the world, after Hartsfield-Jackson Atlanta International Airport which saw 96 million passengers pass through it last year. London Heathrow was the third busiest in the world with over 73 million passengers. The new terminal reflects research by the Bank of America Merrill Lynch which found that there were 109 million Chinese tourists in 2014, who spent $164 billion. These figures are a dramatic increase from the 10 million outbound tourists in 2000.
