How Much Does It Cost to Renovate in Victoria in 2026?

An internal renovation in Victoria in 2026 typically costs anywhere from about $25,000 for a cosmetic refresh to $500,000+ for a whole-home transformation. Most substantial internal renovation projects land between $100,000 and $300,000** once you include a kitchen, a bathroom or two, some structural change and the professional fees and contingency around them. Where you land comes down to scope, your home's condition, and how early you get the big decisions right.

Here's the breakdown — by room, by total budget, and the costs most homeowners forget.

Renovation cost by room (Victoria, 2026)

These are build ranges for mid-range finishes using licensed trades. They climb with layout changes, premium finishes and difficult sites.

Renovation cost by total budget

A simple way to sanity-check your wish-list before you design:

• Around $50,000 — cosmetic upgrades plus, at a push, one modest wet area or a partial kitchen if scope is tightly controlled.
• Around $100,000 — a solid kitchen and one bathroom, or a kitchen plus meaningful internal re-planning.
• Around $200,000 — significant internal reconfiguration, or multiple quality wet areas and a major kitchen (no extension at this price).
• $250,000–$500,000+ — a small single-level extension, multiple wet areas, real structural change and higher specification.
• $500,000 and above — a significant single-storey extension and internal remodelling; at the higher end (upwards of $800,000) this may include a first-floor addition.

These aren't quotes — they're bands to match your scope to before drawings start, not after.

Why "per square metre" can mislead you

You'll see rates quoted — roughly $3,500–$5,500 per m² for ground-floor work, $4,000–$5,500 per m² for second-storey additions, and more again for kitchens and bathrooms. They're useful for an early sanity-check, but dangerous as a budget, because:

• Fixed costs don't scale. Surveys, soil tests, engineering, design, energy reports and the building permit don't halve when you halve the floor area.
• Small + complex costs more per m² than large + simple. A tiny bathroom can out-price a big bedroom extension per square metre.

Use m² rates to cross-check, never to quote.

What actually drives your budget up or down

Across kitchens, bathrooms and extensions, the same four levers move the number most:

1. Layout changes and services — moving plumbing, gas, switchboards or knocking out walls brings in engineering, permits and extra trades.
2. Waterproofing, tiling and structure — non-negotiable in wet areas and among the most expensive components per m².
3. Fixtures and finishes — you can spend $800 or $8,000 on a bath; mid-range across a room usually holds the budget steady.
4. Site and building fabric — upstairs locations, tight access, asbestos, rotted subfloors and older stock all add cost that never shows in inspiration photos.

The hidden costs that blow Victorian budgets

Most homeowners budget for the kitchen and the bathroom. The budgets that blow up ignore the line items around them:

• Compliance catch-up — bringing old wiring, plumbing, structure and waterproofing up to current standards once walls are open.
• Site preparation — demolition, asbestos removal, waste, protection, temporary fencing.
• Professional reports — soil tests, engineering, energy assessments, surveying, flood/heritage documentation.
• Service upgrades — switchboards, mains, drainage, sometimes works in the street.
• Temporary living — storage, alternative cooking/bathing, even partial relocation.

The 7-star energy rule most homeowners miss

Victoria adopted the National Construction Code's 7-star NatHERS energy rating requirement (effective May 2024). It kicks in when your renovation touches the building envelope — external walls, windows, the roof or the floor. An internal-only kitchen renovation doesn't trigger it, but adding a room, enlarging windows or altering external walls does. When it applies, your building surveyor will require a NatHERS compliance assessment, which adds roughly $800–$2,500 in assessment and documentation for a residential project — and may require upgraded insulation, glazing or sealing to the existing home that wasn't in the original budget. Confirm with your building surveyor before you finalise scope.

Always carry a contingency

Almost every credible guide recommends 10–15% contingency on top of your build cost (15–20% for older homes or structural work). On a $200,000 renovation, that's $20,000–$30,000 parked for the surprises older Victorian housing always hides. Without it, a rotted joist becomes a "blowout" instead of a renovation simply behaving like one.

And budget the whole envelope, not just the builder's number: professional fees typically add 10–20%, and extensions often carry another 20–30% in fees, permits and prelims on top of the raw build.

Why 2026 quotes are higher than you expect

If today's quotes feel steep versus a few years ago, it's not just margins. Material volatility, labour shortages, tighter energy and compliance rules, and more conservative pricing after a run of builder failures have all pushed costs up — many builders now assume around 4% annual escalation. Very low bids in this market are usually the ones leaving something out.

Don't overcapitalise

A renovation adds value when the spend suits the suburb. A useful guide: keep total spend (purchase + renovation) sensible against your street's ceiling, and spending 15–20% of property value is easier to justify the longer you'll stay. Renovate for yourself, but price like the market — know your suburb's ceiling before you design.

The real answer to "how much will it cost?"

Here's what 25 years at the kitchen table teaches you: the price isn't decided by the builder's quote — it's decided months earlier, by the decisions you make (or skip) before anyone prices anything. An incomplete brief, a quote missing scope, no contingency, and decisions made out of order are what turn a $150,000 idea into a $220,000 project.

Get the brief and the budget right first, in the right order, and the rest gets a lot easier.
