Changing Cities: Singapore, the Garden City | Digital Sustainability |

This project is a futuristic take on nature, as well as an awe-inspiring vision for the future of a city.

Gardens by the Bay, set in Singapore’s Marina Bay downtown area, has been open less than a month, but it’s already changing the face of the country. The project, which cost $810 million to build, covers the space of 177 football fields and houses 80 percent of the world’s plant species.

Visitors take in awe-inspiring views, including the world’s tallest cooled conservatories, housing some of the most endangered habitats and plants in the world, and a grove of 18 gigantic solar-power, man-made “supertrees” ranging in height from 25 to 50 meters, all designed to collect rainwater.

Gardens by the Bay is also a marvel of sustainable energy and water usage. An underground biomass boiler system that runs on tree and grass clippings and organic waste has been installed. The boiler system, along with onsite solar-photovoltaics, generate energy to cool the garden’s two conservatory domes. Water collection from the supertrees acts as another imaginative irrigation source.

Singapore Prime Minister Lee Hsein Loong calls the new garden project “an icon of Marina Bay” and “the latest manifestation of Singapore’s Garden City vision.”
