The conservatory complex at Gardens by the Bay, Singapore, is made up of two cooled conservatories – the Flower Dome and the Cloud Forest. They are situated along the edge of Marina Reservoir. The conservatories, designed by WilkinsonEyre and Grant Associates, are intended to be an energy-efficient showcase of sustainable building technologies and to provide an all-weather edutainment space within the Gardens. Both are very large (around ) and the Flower Dome is the world's largest columnless glasshouse.
