Named the “Jewel Changi Airport,” or “Jewel,” the glass dome will include 1.4 million square feet of retail, hotel, restaurant and entertainment space, all connected by multi-level gardens and lush walking trails known as the “Forest Valley.” The centerpiece, “Rain Vortex” will be a 40-meter-tall waterfall fed by recycled rainwater that cascades from the dome’s oculus.
Support for the dome will be provided by tree-like structural columns that ring the inside edge of the “Canopy Park” roof garden, designed in conjunction with PWP Landscape Architecture, and gathering space at the dome’s upper level.
