KPF and Heatherwick Studio have revealed the design for the fifth terminal of Changi Airport in Singapore. The concept behind it revolves around the concept of “airport as a city”, presenting itself as a social extension of the namesake district of Changi, at the eastern end of Singapore. The terminal is planned to add a capacity of 50 million passengers per year. Instead of a single monotonous structure, the terminal is comprised of a series of human-centered social spaces, offering different qualities of light, atmosphere, and experience to both visitors and residents of Singapore.
