Starting on 17 April, travelers flying through this world transportation hub will find an addition to the airport that is approximately over 1.4 million square feet, and cost a reported $1.24 billion to build.
The building measures 134,000 sq m and contains a glass and steel donut-shaped roof that spreads over 200 m and its widest point, providing an almost column-free interior. The roof will drop rainwater from a hub oculus 7 stories down.
This waterfall system, improves the Rain Vortex, will be in continuous use, helping to chill the interior. During the region’s frequent thunderstorms, rainwater will flow at more than ten-thousand gallons per minute. The rainwater will also be used for landscape irrigation systems and building services.
The waterfall will be placed in the Forest Valley, a terraced indoor forest with walking seating and trails. An inter-terminal train will cross through the garden, providing visitors with limited time a glimpse of charming greenery.
Another standout feature of the jewel is titled the Canopy Park. This will provide 14,000 sq m of attractions adding a suspended glass-bottom bridge walk, a hedge mirror and maze, and art installations. There will also be an event plaza capable of accommodating one-thousand people. Further, there will be restaurants, retail space, a 130-room hotel, and bars.
The project will be rated Green Mark Platinum, which is green Singaporean building, and in addition to its rainwater collection, will feature wonderful shading and a best ventilation system.
The airport also boasts Forest Jewels Valley, which is a four story garden full of walking trails. It will be one of the biggest indoor plant collections in all of Singapore, which is already famous for over-the-top shows of flora.
