COVID-19 Precinct Update

The interior of a modern workspace at Parramatta Square


As one of the largest commercial developments in Australia, Walker recognised the opportunity to set a new benchmark in sustainability at Parramatta Square.

From design to development and continuing with our ongoing operations, environmental performance is always front of mind at Parramatta Square, demonstrated by our market leading Green Star and NABERS ratings.

We consider sustainability to not only be a responsibility, but also an opportunity to demonstrate the positive impacts that can be made when you choose to act. See how your recycling efforts within the precinct can make a difference.

The awarding of 6 Star Green Star – As Built rating for the first two completed towers within the Parramatta Square precinct at 3 and 4 Parramatta Square was achieved through their efficient energy use, low emissions, strong public transport links, materials selection, technology and innovation.

Most importantly, 4 Parramatta Square achieved a 6 Star Green Star - Interiors rating as well as a 6 Star Green Star - As Built rating - the first and only building in Parramatta to do so, providing not only carbon emissions reduction, but also increased comfort and wellbeing benefits to the thousands of government workers housed in the tower, at capacity.

3 Parramatta Square has achieved 6 Star Green Star ratings for both the base building and the tenancy and 5.5 Star NABERS Indoor Environment Rating through high occupant comfort and wellbeing, without compromising energy and water efficiency.
