Key Details
  • About The Project

    Sydney Observatory is one of the most significant sites in the nation’s scientific history. It was first constructed in 1858. Little has changed on Observatory Hill since Sydney Observatory first opened its doors 158 years ago, back in 1858. For most of its history, the western part of this sandstone building functioned as a research observatory, while the eastern rooms served as the residence of the government astronomer and his immediate family. Recently, Heritage 21 has been consulting on paint removal and re painting systems to deal with the existence of toxic lead paint and calcimine on the internal and external walls.

  • What was done

    Over a period at least 6 months, Heritage 21 inspected the Observatory Building and the Settlers Cottage. These two buildings form part of the Observatory Campus. It was noticed that there is extensive ingress of moisture into the walls of both buildings which in turn has caused the paint to delaminate. Heritage 21 wrote up a specification for remedial action to remove the paint and repaint with an appropriate painting system.

Why was the work undertaken?

It was Heritage 21 that pointed out MAAS (Museum of Applied Arts and Sciences) that there were problems with the paint on the walls in terms of toxicity and delamination. On this basis, Heritage 21 drew up specifications for the paint removal and the reapplication of a new painting system capable of dealing with the ambient conditions on site.

Who was the work completed for?

Museum of Applied Arts and Sciences


As we write, the work is in progress. However, the main issue is the problems have been identified and a remedial system has been set in place.

“Sites with heritage values present great opportunities, however often can be easily derailed if clear, concise and timely advice is not provide at the earliest stages of site planning. I have worked with Heritage 21 over numerous projects across Sydney and have found them to be valuable project partners in the development process. ”
