"538 Bourke St., formerly known as the "Grand Central", will soon become the home of IAG, who will occupy the majority of this 27 level, 43,000sm (NLA) new office tower in Melbourne's prime CBD. With a "5 Green Star Rating" performance targeted, the client has selected an Armstrong ceiling system comprising Ultima ceiling panels and PeakForm™ suspension grid. This combination provides high performance acoustics and light reflectance, with the longevity, low maintenance costs and low embodied energy of a conventional two way exposed grid.
