Singapore’s soon to open Jewel Changi Airport, designed by Moshe Safdie’s architecture firm, completed the world’s tallest indoor waterfall. Featuring the waterfall, a lush indoor forest, and a green trail of airport amenities, the scheme is set to open on April 17th of this year.
The building measures 134,000 sq m (1,442,364 sq ft) and comprises a glass and steel donut-shaped roof that spans over 200 m (650 ft) at its widest point, offering an almost column-free interior. The roof will drop rainwater from a central oculus seven stories down.
