Giurgola placed an emphasis on the visual aesthetics of the building by using landscape architect Peter G. Rolland to direct civil engineers, a reversal of the traditional roles in Australia. Rolland played a pivotal role in the design, development and coordination of all surface elements including pool design, paving, conceptual lighting and artwork locations. Horticultural experts from the Australian National Botanic Gardens and a government nursery were consulted on plant selection. Permanent irrigation has been limited to only the more formal areas. Irwinconsult was commissioned to provide structural engineering, including quality assurance of all structural elements, to deliver a building with a designed life-span of 200 years.
