Historic buildings and architectural elements

Built heritage, including historic buildings and architectural elements, is a tangible link to our past. O’Sullivan Conservation has undertaken a range of conservation projects for historic buildings and structures in environments as diverse as hospitals, universities, and courthouses throughout Australia, and heritage structures as far as Antarctica.

In undertaking conservation projects of built heritage, our conservators follow the ethical guidelines of minimal intervention, using appropriate and reversible materials to the extent possible, and thorough documentation of all conservation treatments undertaken.


O’Sullivan Conservation acknowledges that we operate and function on the lands of the Darkinjung people.

We respect and honour Aboriginal and Torres Strait Islander Elders past, present and future. We acknowledge the stories, traditions and living cultures of Aboriginal and Torres Strait Islander peoples on this land and commit to building a brighter future together.

We are proud partners of Reconciliation NSW and support reconciliation in our community.
