Engineer Buro Happold designed the glass and steel bagel-shaped roof, which spans more than 200 metres at its widest point, while Peter Walker and Partners Landscape Architects created the climate-controlled indoor forest.
Singapore experiences frequent thunderstorms, so the Rain Vortex has been designed to funnel rainwater at a rate of 10,000 gallons per minute.
This stream of water will naturally cool the air under the dome, with the captured water will be re-used in the building.
Safdie Architects, founded by Israeli-Canadian architect Moshe Safdie in 1964, began work on the Jewel Changi Airport in 2014.
In an interview with Dezeen last week, Safdie called on architects to design for climate change by making sure their structures can respond to more extreme weather and temperature conditions.
“For something like Jewel, [if it] was in a city with a temperate climate, my dream would be would be to open it up to the air and nature when the weather is wonderful,” Safdie said.
While the technology to create a retractable roof that’s compatible with indoor air conditioning isn’t available yet, the Jewel still has plenty of attractions for visitors.
Terraces filled with 200 species of plant surround the waterfall in an area called the Forest Canopy, with trails for visitors to walk along. Five stories of the Jewel Changi Airport building will be filled with shops and restaurants, with an indoor park on the fifth level.
At night, the Rain Vortex will have a 360-degree light and sound show projected onto it with a system designed by WET Engineering.
The new building is connected to Singapore’s public transport system and links to terminals one, two and three via pedestrian bridges.
As well as being a portal to the airport, the 134,000-square-metre glass-encased building is meant to be a retail and entertainment destination in its own right.
