Sydney
Based in Haymarket on Gadigal Country, our Sydney team is GML’s founding office — established in 1989 and home to our largest and most diverse group of heritage practitioners.
Experience and expertise
As GML’s head office, the Sydney team brings together the full breadth of our disciplines — leading complex, large-scale, and nationally significant projects while supporting our Melbourne, Canberra, and Brisbane teams on work that spans the country.
We work across all scales, from neighbourhood character studies to major infrastructure, and across all heritage types — built, landscape, First Peoples, archaeological, and maritime.
Our clients include government agencies, cultural institutions, architects, planners, and developers.

How we work
Trusted advice across complex projects
Our Sydney team is experienced in navigating the full range of heritage regulatory frameworks — working with councils, state agencies, and Commonwealth authorities to deliver advice that is clear, credible, and actionable. We are particularly well regarded for our work on major infrastructure, twentieth-century heritage, and adaptive reuse.
Resilience & heritage risk
We are national leaders in heritage resilience — helping owners, managers, and governments understand and address the risks that climate change and disaster pose to significant places, and developing strategies that protect what matters most.
First Peoples heritage
We work with Aboriginal and Torres Strait Islander communities and Traditional Custodians to understand cultural values, support self-determination, and deliver cultural heritage management that is respectful, rigorous, and aligned with legislative requirements.
A collaborative network
We work alongside architects, planners, engineers, landscape architects, archaeologists, conservators, and other specialists — bringing together the right expertise for every project.
Where others see heritage risks, we find collaborative solutions.
