Assessment of Heritage Fabric

A place considered to be of potential heritage significance is assessed using guidelines established by State and Federal government heritage authorities, namely the Australian Heritage Commission and the NSW Heritage Office. These guidelines set out assessment criteria that broadly encompass the four possible values of heritage significance:

  • Historical significance 

  • Aesthetic significance

  • Research/technical significance 

  • Social significance 


Process of Heritage Assessment

Once the values of heritage significance have been determined, they are then graded to assess their relative contribution to the heritage value of the place. Gradings are:

1.     Exceptional (rare or outstanding element directly contributing to an item’s significance)

2.     High (high degree of original fabric; demonstrates a key element of the item’s significance)

3.     Moderate (elements with little heritage value, but which contribute to the overall significance of the item)

4.     Little (alterations detract from significance; difficult to interpret)

5.     Intrusive (damaging to the item’s heritage significance).


The assessment of significance also requires that the level of significance be determined.

1.     National significance (significant to the people of Australia).

2.     State significance (significant to the people of NSW).

3.     Local significance (significant within the local government area).
