John Gorton Building Refurbishment & Workplace
King Edward Terrace,Parkes, ACT, Australia
Transforming a Federal Government Workplace

Hunter Mason delivered the 6,000sqm fitout and refurbishment of the John Gorton Building, transforming the bunker, basement and sub-basement levels into a contemporary workplace for the Australian Government. Delivered over six months, the project created a high-quality workplace environment incorporating new meeting spaces, collaboration areas, upgraded amenities and integrated building services, supporting the evolving needs of a modern Federal Government workplace.
Beyond the workplace fitout, the project included significant landlord works to improve accessibility, compliance and long-term building performance. Key works included the construction of a new fire egress stair through an existing glazed atrium, the installation of a DDA-compliant lift, and the careful removal, restoration and reinstatement of the building’s heritage-listed feature ceiling. The project required meticulous planning, specialist coordination and disciplined delivery to successfully integrate modern workplace standards within one of Canberra’s most significant government assets.
Working closely with the client and project team, Hunter Mason successfully coordinated complex interfaces, specialist trades and stakeholder requirements to deliver the project with certainty and precision. The completed workplace reflects our capability to deliver large-scale, technically complex workplace transformations, creating environments that support the evolving needs of Federal Government while delivering enduring value for our clients.
