In the final months of 2016, the $660 million Chadstone shopping centre in Melbourne completed its 40th expansion and was ready to be be opened to the public. It's expansion was overseen by developers Gandel Group and Vicinity Centres, Probuild and architects CallisonRTKL and the Buchan Group.
At more than 200,000m2 Chadstone is Australia’s number one destination for shopping, dining and entertainment.
This extensive project added more than 34,000m2 of space including:
The gridshell roof is an iconic feature and a milestone in structural design innovation. Designed, sourced and manufactured in Europe, the gridshell system is a relatively simple solution to an extremely complex form that also keeps material usage to a minimum. Arching over the extended mall and soaring some 25 metres above the ground floor mall, the structure helps bring the feeling of an outdoor European shopping precinct into an indoor Australian mall with open, column-free spaces that keep interior spaces cool, light and airy.
The glass roof follows the line of the shopping centre below – a 3D, wave-like form that gives the illusion that it’s moving over the heads of shoppers. The roof was meticulously planned and constructed using an intricate jigsaw that required six tower cranes to build.
From quadrilaterals through to triangles, each of the 2,700 panes of double-glazed high performance glass is unique and varies from around 1.2m2 to 7.4m2 in size. An incredible feat of engineering and a work of art in itself, the self-supporting structure uses steel and glass elements sourced from Europe, weighing in at between 100kg to 300kg each. The roof is the first of its kind on the continent.
Probuild Group Managing Director, Simon Gray said Chadstone is now an active investment in the future of Australian retailing.
“Shopping centres are no longer just about the convenience – they’re a place for people to gather and socialise. So it’s important that the right environment is developed to support community interest and growth," Mr Gray said.
“Centres are targeting international tenants now and A-listed brands. But they won’t come unless you provide them with an A-Lister environment. It’s about getting the look and feel right – and it’s often about pushing the boundaries of architecture, design, construction and innovation.”
The project was awarded a 5 Star Green Star design rating by the Green Building Council of Australia.
