Gardens by the Bay is an ambitious project set to transform Singapore into one of the greenest cities on earth. The jewel-in-the-crown is the largest waterfront garden on the equator but building it was a mega-undertaking. A flat piece of reclaimed land was transformed into Singapore’s largest park, challenging not only the designers, but also engineers who must create a raft of new green technologies. This film is produced by Singapore-based Beach House Pictures for National Geographic.
