What the overlay is actually protecting
Heritage overlays in Melbourne’s inner suburbs almost always protect the streetscape: the facade, the roof form as seen from the footpath, the front fence and the rhythm of the street. They rarely protect the 1980s lean-to on the back of the house.
What is usually approvable
- A rear extension set back behind the original roof ridge, so it is not visible from the street.
- A second storey set well back, subordinate in height and finished in a recessive material.
- Internal reconfiguration, in most overlays, without any planning approval at all.
- Reinstating original detail — verandah, fence, colour scheme — which councils actively encourage.
What is usually not
Demolishing a contributory facade, raising the front roofline, replacing original windows on the street elevation, or building a garage forward of the building line. If your plan depends on one of these, it is worth knowing before drawings are commissioned.
How the application works
A heritage impact statement is prepared by a heritage adviser and lodged with the planning application. Council’s heritage officer reviews it and usually comes back with conditions rather than a refusal, provided the design respects the setback and subordination principles above.
We engage the heritage adviser before pricing the work, so the quote you sign reflects a design that will actually be approved.
