Holdmark Innovation Award

The annual Holdmark Innovation Award recognises excellence and innovation in the built environment.

Supported by Holdmark, the Award is presented by Powerhouse to a project that demonstrates excellence and innovation in architecture or engineering in the built environment. The award will spotlight one outstanding Australian-designed project completed between 1 January 2025 – 31 December 2025 that provides solutions to challenges experienced in Australia’s urban landscape. The winner will receive a A$15,000 cash prize.

Holdmark Property Group, under the leadership of founder and chief executive Sarkis Nassif, has committed A$10 million towards Powerhouse Parramatta. This remarkable investment supports the establishment of the Holdmark Gallery, the Holdmark Innovation Award and an Urban Transformation Summer School with Western Sydney University.
