Cooled Conservatories, Gardens by the Bay

Cooled Conservatories, Gardens by the Bay


Architect: Wilkinson Eyre Landscape Architects: Grant Associates Client: National Parks Board

The Gardens by the Bay are an outstanding example of sustainability in action, not only representing best practice but also communicating important messages about these issues to a wide public.

Two contrasting glasshouses covering more than two hectares (making them the biggest climate-controlled greenhouses in the world) feature a dry Mediterranean climate in the shallow inverted bowl, and a cooler, moist environment in the conical structure complete with a ‘mountain’ down which a waterfall descends, raising humidity levels and supporting the lush vertical planting – and a helical walk that winds in and out of a series of exhibitions about climate change.

Both biomes comprise a superstructure of radial steel ribs paired with a steel gridshell forming the substructure. Low-energy glass lets in 64% of the light but admits only 38% of the corresponding solar gain.
