What a renovation
costs in Fitzroy

Fitzroy is the hardest suburb in Melbourne to build in, and the numbers show it. Terrace housing on small allotments, almost universal heritage coverage, and sites with no vehicle access at all. A thirty square metre extension here can cost what forty-five costs two suburbs north.

Indicative ranges

Rear extension
$285k – $385k

30 m², mid finish, one new wet area, heritage, no vehicle access

Second storey
$470k – $640k

40 m², mid finish, one new wet area, heritage-sensitive design

Full renovation
$540k – $735k

95 m² internal, mid finish, new kitchen and bathroom

Rates: Archicentre Australia CostGuide 2026 · GST inclusive

What drives cost here

Area is not the driver — access is

The single most expensive fact about a Fitzroy site is usually that nothing can drive onto it. Materials come through the front door or over the roof by crane, spoil goes out the same way, and the labour cost of that dwarfs the square metres.

Near-universal heritage coverage

Most of Fitzroy sits within a Yarra heritage overlay. Rear additions are still achievable, but form, materials and visibility from the street are all in scope, and the design process is longer and more iterative.

Party walls and neighbours

Terraces share walls. That brings protection works, dilapidation surveys, and negotiated agreements before a single brick moves — cost that has nothing to do with your own house.

Small blocks push work upward

With little room to extend outward, Fitzroy projects tend to go up or excavate down. Both are structurally involved and neither is priced by the simple square-metre rates published for extensions.

Typical Fitzroy projects

ProjectWhy it costs what it doesRange
Rear extension to a single-fronted terraceSmall in area, expensive in delivery. Access, party-wall protection and heritage approval carry most of the cost.$285k – $385k
Second storey behind a retained facadeDesign has to satisfy the overlay before it satisfies you. Expect a longer approval path and more drawings.$470k – $640k

Minimum project size. AE Index works on structural renovations and extensions from $150,000. Smaller jobs and single-trade work are referred on rather than quoted.

Common questions

Why does a small Fitzroy extension cost as much as a larger one elsewhere?

Because square metres are not what you are paying for. Access restrictions, party-wall protection, heritage approval and crane time are largely fixed regardless of how big the addition is. A thirty square metre job carries almost the same overhead as a fifty square metre one.

Can I extend a heritage-overlaid terrace at all?

Usually yes, at the rear. Overlays are principally concerned with the street presentation and the contribution the building makes to the streetscape. What sits behind, out of sight, has more latitude — though materials and form still get scrutiny.

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.

Do I need agreements with my neighbours?

If you share a party wall or need to work near the boundary, almost certainly. Protection work notices and dilapidation surveys are standard practice on terraces, and they are far cheaper to arrange before work starts than to argue about afterwards.

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.

AE Index publishes indicative cost data for Melbourne residential renovation. Estimates are budget-setting figures, not quotes, and assume a standard site with no undisclosed structural, drainage or contamination issues. Square-metre rates are drawn from the Archicentre Australia CostGuide 2026, an independently published Australian cost guide, and are GST inclusive. Site adjustments are AE Index's own and are labelled wherever they appear. AE Index refers projects to a builder from its verified network and receives a fee on work that proceeds.
