Changi in Singapore, which has long striven to enthral and entertain its users, outdid itself with its new “Jewel” extension to its existing terminals, essentially a shopping mall and nature-based theme park. From a great oculus in its glass roof descends the “rain vortex”, a funnel of falling water described as the “world’s tallest indoor waterfall”. It has a “butterfly garden”. It has the Shiseido Forest Valley, a 900-tree, 60,000-shrub indoor landscape named after the Japanese-based personal care company Shiseido. The forest concept is, in marketing terms, a good fit with its corporate mission: “Beauty innovations for a better world.” – The Guardian
