 The design of the shopping centre was modelled around suburban shopping centres such as Chadstone Shopping Centre in Melbourne and Chatswood Chase in Sydney, rather than based upon traditional CBD arcade layouts.Before commencing construction, the developers committed to achieving a 4.5-star Australian Building Greenhouse Rating for the project.This added 10 percent to the cost of the building, and the developers indicated that achieving a 5-star rating would be prohibitively expensive.
