What a renovation
costs in Brighton
Brighton has the largest blocks and the biggest budgets in this set, comparatively light heritage coverage, and one cost factor almost nobody prices for: the sea. Salt exposure changes what materials and fixings a coastal build actually needs.
Indicative ranges
55 m², high finish, one new wet area

What drives cost here
Coastal exposure
Proximity to the bay drives material selection — marine-grade fixings, corrosion-resistant hardware, more robust external finishes. It is a specification premium, not a labour one, and it is real.
Very large blocks
Space to extend outward, excellent machinery access, and no access premium on most sites. Structurally among the easiest premium suburbs to build in.
Selective heritage coverage
Bayside protects defined precincts rather than the whole suburb. Plenty of Brighton sits outside any overlay, which shortens approval considerably.
Strong rebuild competition
Large blocks and lighter controls make knockdown-rebuild a genuine alternative. Price both before committing — the gap is narrower here than in a heritage precinct.
Typical Brighton projects
| Project | Why it costs what it does | Range |
|---|---|---|
| Rear extension to a large family home | Good access, sound footings, high specification and coastal-grade materials. | $410k – $555k |
| Second storey addition | Room and access make it straightforward; specification drives the cost. | $460k – $620k |
| Whole-house renovation | Large footprint, high finish, coastal material selection throughout. | $1005k – $1360k |
| Kitchen only | Below our minimum — referred to a single trade. | $35k – $70k |

Common questions
Does being near the beach add to building costs in Brighton?
Yes, through specification rather than labour. Salt exposure calls for marine-grade fixings, corrosion-resistant hardware and more robust external finishes. It is a material premium that published square-metre rates do not distinguish.
Is all of Brighton heritage protected?
No. Bayside maintains defined heritage precincts rather than blanket coverage, so a significant portion of the suburb sits outside any overlay. Check your planning property report — it materially changes the approval path.
Should I renovate or rebuild in Brighton?
Genuinely worth pricing both. Large blocks and lighter heritage controls make rebuilding viable in a way it is not in an overlay-covered suburb. Renovation still wins where the existing structure is sound and characterful.
What is not included in these ranges?
Landscaping and external works, appliances, furniture and window furnishings, council planning application fees, driveway reinstatement, and anything found once walls are opened. Design fees, engineering, building surveyor, permit levy and energy assessment are included.

When you are ready to build
AE Index is not a building company. When a project is ready to be priced properly, we pass it to a builder from our verified network — who will walk the site, inspect what is under the floor, and put a fixed price in writing. We are paid a fee by them on work that proceeds, and you are under no obligation to use them.
- Current domestic builder registration, confirmed with the Victorian Building Authority
- Domestic building insurance current and sighted
- Two completed projects contacted directly — not supplied testimonials
- Fixed-price contracts with a written variations policy
- Re-checked annually, and removed from the network on any lapse
