When the Royal Melbourne Institute of Technology unveiled the Ashton Raggatt McDougall-designed Storey Hall refurbishment, with its shapes and spaces inspired by fractal geometry, there was no denying that a singular piece of architecture had been achieved.
Fifteen years later, the latest joint venture of these two organisations is receiving comparable attention.
Dubbed the Green Brain, the rooftop extension to the RMIT Building 22 is not only a logical continuation of its predecessor, but is also an exploration of thought itself, says Howard Raggatt, founding director of ARM.
"In a way, it's a fairly simple extension of the Penrose tile treatment we devised for Storey Hall next door. On the Storey Hall project, we were working at the forefront of computer-aided design. Now, CAD-CAM has become such an inherent part of design and manufacture that a whole new level of possibility is available to us.
"We were interested in exploring the whole inventive, creative culture of the university being tied up with this idea of a consciousness in matter outlined by the mathematical physicist, Roger Penrose, so it seemed an appropriate conceptual extension to explore the infinite continuation of that imagery to take it beyond the five-fold rotational symmetry of Penrose tiling."
