The royal visit marks a double celebration for the design team, as the project has been shortlisted for two awards at the World Architecture Festival, to be staged in Singapore from 3 to 5 October this year.
The duke and duchess visited the Cloud Forest Cooled Conservatory and Supertrees Grove as well as planted a tree and met the design team. It formed part of their Asia Pacific tour celebrating the Queen’s Diamond Jubilee.
Gardens by the Bay, 101ha in size, will eventually be one of the largest gardens of its kind in the world comprising Bay South, Bay East and Bay Central gardens. Grant Associates drew up the masterplanned the first and largest of the three zones.
Bay South stretches over 54ha and opened in June 2012. Bay East and Bay Central are yet to be completed. The completed section includes 18 Supertrees - 25m to 50m vertical gardens that light up at night.
Two giant Cooled Conservatories designed by Wilkinson Eyre Architects house Mediterranean and tropical climate plants. The project also includes several gardens, themed on plants, people and planets.
"It’s fantastic to see the way both locals and international tourists embrace Gardens by the Bay so warmly," said Grant Associates’ director Andrew Grant. "As a practice, were very interested in the principle of multifunctional infrastructure.
"The Supertrees are a great example of dramatic architectural design, coupled with sustainable technologies. They’re also stunning backdrops for climbing plants in the daytime and projected light displays at night."
Project director Keith French said: "At one level this is a dramatic 3D garden experience. At another it is a sophisticated example of integrated environmental design with intelligent energy and water management systems."
