The OCBC Skyway is the latest addition to Singapore's innovative project "Gardens by the bay," an aerial walkway that hopes to challenge the idea of urban spaces.
The 18 giant "supertrees" are a completely different kind of skyscraper, providing spectacular views over the Marina Bay, which is due to house a number of gardens and tropical conservatories.
The "branches" of the trees, currently still under construction, will work like garden trellises, a canopy of vines, flowers and leaves providing shade from the humid Singapore climate.
The silhouettes of the trees, partially completed
Look down from 25-50 metres, the trees form a striking part of the city skyline, as well as hoping to convey an environmental message.
Once completed, they will collect rainwater and generate solar power. They will also allow hot air to be released from the conservatories below, in a kind of urban ecosystem.
The Gardens By The Bay hope to be complete in June 2012, with the tallest 50-metre tree featuring a bistro.
