Singapore's Changi Airport is already renowned for its pleasant human touches such as butterfly gardens and rooftop pools – but the new 'Jewel' complex could very well make you forget you're in an airport altogether.
Nestled nest to Terminal 1 where a carpark once stood, and due to open in early 2019, the $1.63 billion project is a climate-controlled glass dome boasting a massive five-story indoor garden larger than even the city-state's Gardens by the Bay domes.
The centepiece will be a 40 metre high indoor waterfall dubbed the Rain Vortex.
The world's tallest indoor waterfall, it's been created by water design firm WET (the aquatic architects behind stop-and-gawk water features at Las Vegas' Bellagio and Dubai's Burj Khalifa) and will use rainwater collected from the building's roof...
... and at night play host to a dazzling choreographed light and sound show.
A suspended 50 metre long bridge with glass panel flooring overlooks the Rain Vortex.
The upper level of Jewel will host Canopy Park, a sprawling 14,000m² garden with several unique 'play attractions' such as elevated nets to can walk (or bounce) along...
... and two mazes (just be sure to find your way out when it's time to board your flight).
Gardens terrace down nearly 30 meters to a central gathering space with informal amphitheater seating.
Then there are animal-shaped topiaries...
... and seasonal floral displays.
Designed by a team led by Moshe Safdie, who shaped the iconic Marina Bay Sands, Jewel could well double for the lair of a billionaire Bond villain, with five floors above ground and a further five basement levels.
Elevated air-conditioned walkways and the automated Skytrain will connect the Jewel to Terminals 2 and 3.
Of course, this is an airport and it is in Singapore, which means the Jewel complex will also contain some 300 shops plus food and beverage outlets.
Also planned is a 130-room hotel plus facilities such as airline lounges – and to promote Singapore as a 'fly-cruise' hub, there'll also be a dedicated cruise departure lounge where travellers flying into Singapore can pick up their cruise boarding passes and check in their bags.
