Entry Description

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.
