What a renovation
costs in Brunswick
Brunswick is the most mixed housing stock of any inner-north suburb — Victorian terraces on the Sydney Road side, solid interwar brick through the middle, and converted industrial buildings scattered between them. What you own matters more here than where you live, and the cost spread reflects that.
Indicative ranges
45 m², mid finish, one new wet area, constrained access

What drives cost here
Solid brick, not weatherboard
Much of Brunswick is double brick or brick veneer rather than timber. That is good news on restumping and bad news on structural change — every new opening needs steel, engineering and propping.
Deep, narrow allotments
The classic Brunswick block runs long and thin. There is usually room to extend rearward, but getting a truck down the side is another matter, and hand-carrying materials the length of the block adds real labour.
Former industrial land
Pockets around the old factory sites carry contamination history and fill of unknown quality. Site investigation is cheap; discovering it after excavation starts is not.
Merri-bek heritage precincts
Overlays cluster along the older streets rather than blanketing the suburb. Two houses on the same street can face genuinely different approval paths — check yours rather than assuming.

Typical Brunswick projects
| Project | Why it costs what it does | Range |
|---|---|---|
| Rear extension to a double-fronted brick house | Removing the rear wall of a load-bearing brick house means steel and engineering before anything new goes up. | $330k – $445k |
| Second storey over solid brick | Existing footings often carry the load better than timber stock, but roof removal and weather protection run longer. | $460k – $625k |
| Warehouse or shopfront conversion | Highly variable. Change of use, fire separation and acoustic requirements can dominate the budget. | Assessed individually |
| Kitchen only | Below our minimum — referred to a single trade. | $25k – $50k |
Common questions
Why is a brick house more expensive to extend than a weatherboard one?
Not always — but structural change is. Opening up a load-bearing brick wall requires steel, an engineer's design, and temporary propping while it goes in. A timber-framed house is far cheaper to cut into, though it usually needs more work underneath it.
My block backs onto a laneway. Does that help?
Considerably. Rear laneway access can remove most of the access premium from a quote, because materials and machinery reach the work directly. It is one of the few site features that genuinely reduces cost, and it is worth telling any builder about early.
What is not in these numbers?
Landscaping and external works, appliances, furniture and window furnishings, council planning application fees, driveway reinstatement, and anything discovered once walls are opened. Design fees, engineering, the building surveyor, the permit levy and the energy assessment are included.
Should I be worried about contamination on a former industrial site?
Worth checking rather than worrying. A soil report early in the process costs a fraction of what a mid-excavation discovery does, and it lets a builder price the job properly instead of loading the quote with contingency.
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.
Plenty of directories call their builders trusted without saying what that means. Ours means five specific things:
- 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
The sensible order is estimate first, referral second. Run the numbers, decide whether the project is viable, and only then talk to a builder.
