Situated at the northern periphery of Melbourne’s Central Business District, the 501 tower stands as the renovated and revitalised octagonal structure constructed for the renowned, though no longer in existence, Australian airline Ansett, in 1978. Designed with uncompromising quality at the time, this building was built to be a cutting-edge flagship among Melbourne’s office towers.

In 2002, PDG acquired the property from Ansett, and by mid-2012, the Zagame Group joined as co-owners with a shared vision of restoring the tower to its former glory. This 17 level commercial tower, conveniently positioned near trams and Melbourne Central train station offers exceptional accessibility for its occupants, as well as a retail podium.  

PDG’s overarching goal was to future-proof this landmark, with a focus on the redevelopment of the structure to shape it into one of Melbourne’s most innovative and inviting workplaces.

To achieve this vision, ADP Consulting were engaged to elevate the building from a 3.0 Star to a 5.0 Star NABERS Building Rating.

To this end, we provided a comprehensive roadmap outlining the necessary works, including phased plans and estimated costs. The recommended enhancements span the installation of heat pumps, modifications to air handling systems, meter upgrades, and selective thermal envelope modifications.
