Unveiled on the Royal Botanic Garden’s 200th birthday, the Calyx is a landmark horticultural, research and education space that showcases ever-changing exhibitions. Central to the Calyx’s design concept was an aspiration to create a ‘jewel in the Garden’, a serene and peaceful building in its distinctive setting, yet one with flexibility for ever changing public exhibitions and events. The geometry of the existing 1988 Arc Glasshouse, designed by Ancher Mortlock and Woolley led by renowned Australian Architect Ken Woolley, guided the architectural development of the Calyx. In co-operation with the landscape architects Mc Gregor Coxall and builders Cockram Construction, the quality, integrity and innovation of the existing structure was retained and enhanced. The circular steel structure of the ‘Iris’ is the most highly visible element of building. Accommodating the foyer, education and retail outlet this circular space, with its retractable walls can be turned into an evening event space.
