Heritage Overlays: What You Can and Cannot Change
14 August 2026
A heritage overlay is not a ban on renovating. It is a set of rules about what is visible from the street — and the rear of your house is usually fair game.
Coastal exposure, sandy soils and a market that expects a high finish. Bayside renovations are detailed differently from the first drawing — materials, fixings and waterproofing all have to survive salt air.
House extensions
A second-storey addition is often the cheapest way to get a bay view out of a block you already own. We assess whether the existing footings and frame can carry it before anything is drawn.
The ground floor usually stays liveable through most of the build; where it cannot, we tell you which weeks up front so you can plan around them.
Full renovations
Within a few streets of the bay, standard fixings and cladding do not last. We specify marine-grade fixings, upgraded waterproofing and finishes that hold their colour, and we say so on the inclusions list rather than burying it in a specification.
Bathrooms, kitchens and laundries are done the same way whether they are part of a whole-house job or a single room on its own.
Modestly, yes — corrosion-resistant fixings, upgraded waterproofing and higher-grade external finishes typically add a few per cent, and it is itemised so you can see exactly where.
Yes. Sandy sites are common through Bayside and are handled with an engineered slab or screw piles, designed from the site classification.
Yes. Where a Design and Development Overlay or Special Building Overlay applies we prepare the response as part of the planning application.
Overshadowing and overlooking are assessed against ResCode at the design stage, so objections are addressed before lodgement rather than after.

From first sketch to handover, a realistic programme for a Melbourne new build — including the approval months most timelines quietly leave out.
Slope is not the problem. Fighting the slope is. How split levels, suspended slabs and honest early engineering keep a difficult site affordable.
