Changi Airport in Singapore will soon undergo an expansion worth approximately $1.5bn.
The aim of this expansion is to connect the three terminals through glass-enclosed walkways.
Known as Project Jewel, the expansion plan will involve the construction of a glass and steel dome-shaped space that will feature airport operations, indoor gardens and retail stores, as well as offer hotel facilities.
It will also feature an indoor waterfall that will pour from the roof of the dome.
The responsibility of designing the airport has been given to Israeli-Canadian architect Moshe Safdie, who is best known for designing Singapore’s Marina Bay Sand Hotel.
Changi Airport Group CEO Lee Seow Hiang said: "We are confident that Project Jewel will be a world-class attraction that Singaporeans will not only enjoy immensely but be proud of."
"To strengthen Changi Airport’s competitive advantage and ensure that we continue to capture passenger mindshare and traffic, we must take deliberate steps to enhance Changi’s attractiveness as a stopover point."
While the construction work on the airport’s expansion will be started this year, authorities hope the work to be complete by the end of 2018.
