The Middle Eastern country of Oman is set to be the location of what will be the worlds largest botanic garden. Together with Haley Sharpe Design, Arup and Grimshaw, the future Oman Botanic Gardens will include 8 habitats, a green forest area, and extensive research and visitor facilities. Construction begins soon, but in the meantime you can see images of the proposed project below.
