The Ian Potter National Conservatory

CHROFI / Acton, Australia

McGregor Coxall collaborated with Sydney architects CHROFI and Atelier Ten to win the competition for a new conservatory to house the tropical collection of the Australian National Botanic Gardens in Canberra. Titled ‘Hovering Cube’, the building is a pristine box clad in a layered skin to optimise environmental performance and provide a stable climate for the plants.

The conservatory will be a key visitor attraction for the botanic gardens. The team have been appointed to the design development phase of the project in which McGregor Coxall shall be devising the configuration of the indoor tropical planting components as well as outdoor planting, designing site linkages plus adding connectivity to the wider site masterplan.
