Most renovation advice online is written as though every Australian house is the same house. It is not.
A home built in inner Melbourne in 1910 has almost nothing in common with a Brisbane timber home from the 1930s, beyond the fact that both are old. What sits inside the walls, what the walls are made of and what the local council allows you to change will all shape your budget before you pick a single colour.
Here is how that plays out across the country.
Why the Age of a House Changes the Whole Plan
The order of a renovation is the same everywhere. Structure first, then services, then linings, then surface preparation, then finishes, then fit-off.
What changes from city to city is the risk sitting inside that sequence. Three factors do most of the work here.
Wall and floor construction decides how easily new cables and pipes can be run. The vintage of the existing wiring and plumbing decides whether you are extending a system or replacing it. Local planning rules decide how much of the outside you are allowed to touch at all.
Melbourne and Its Victorian and Federation Housing
What the walls are made of
Melbourne’s inner suburbs are dominated by solid brick and weatherboard homes built before 1960. Lath and plaster walls are common, and solid brick construction offers no cavity to thread new services through.
That single detail is why chasing walls and lifting floors takes up so much of a Melbourne renovation timeline. Nothing hides easily in a house that was never built to hide anything.
Where the money usually goes
The switchboard is the pressure point. Homes of this era were wired for a fraction of the load a modern household puts through them, and rubber or cotton insulated cable still turns up behind skirtings.
In suburbs where most of the housing stock predates the 1960s, an electrician kew homeowners have worked with before will usually open the switchboard first. What is found there tends to reset the schedule for every trade that follows.
This is discovered work rather than planned work, which is exactly why so many Melbourne budgets move at the rough-in stage. Booking the assessment early is the cheapest thing you can do.
What heritage overlays control
Councils across the inner east and inner north apply overlays that protect the facade, the roof form, and anything visible from the street.
Interiors are usually far less restricted. Most owners find the best return sits behind the front door, where the rules are lighter.
Sydney and the Cost of Working on Tight Sites
Terraces, semis and access
Sydney’s older stock leans heavily on terraces and semi-detached homes. Narrow lots and shared walls mean no side access, so every sheet of plasterboard and every skip load has to come through the front of the house.
That access problem becomes a real line item rather than an inconvenience. Attached dwellings also bring party wall considerations, and a dilapidation report on the neighbouring property is worth doing before work starts.
The approvals load
The bigger variable is paperwork. Whether your project qualifies as Complying Development or needs a full Development Application will shape your timeline more than the build itself.
Owners are often surprised that approval, not construction, is the longest phase. If a roof is part of the scope, understanding roof replacement costs early helps keep the application realistic.
Brisbane and the Elevated Timber Home
The Queenslander build
The classic Queenslander is timber framed, lined with VJ boards and raised on stumps. That elevation is a genuine advantage, because plumbers and electricians can access the underside of the house without tearing up floors.
The trade-off sits in the structure itself. Stump replacement and subfloor repair are the costs that most often appear once someone actually gets under there.
Climate-driven choices
Humidity, termite activity, and wind loading all push Brisbane decisions in a different direction to southern cities. Ventilation matters more, and timber treatment is not optional.
Insulation choices differ too, because keeping heat out is the priority.
Adelaide and the Demands of Stone and Render
Solid walls with no cavity
Adelaide’s older homes are frequently bluestone, sandstone or rendered solid masonry. Solid walls with no cavity change how insulation is approached and how moisture behaves.
Rising damp is the recurring problem. Sealing the wrong surface traps moisture inside the wall instead of letting it escape, which makes the damage worse rather than better.
Why preparation dominates the finishing budget
Hot, dry summers and cool, wet winters cycle the substrate constantly. Repointing, crack repair and sealing all have to happen before any coating goes near the wall.
On solid stone and rendered facades, house painters Adelaide owners engage will typically itemise substrate repair separately from the coating work. That separation is a good sign, because it shows the quote has been priced on the condition of the wall rather than its square metreage.
If a painting quote for an older Adelaide home looks unusually cheap, preparation is almost always the thing that has been left out.
Perth and Hobart in Brief
Perth’s housing stock is newer on average, and double brick construction is the norm. Sandy soils and reactive footing behaviour drive more of the structural conversation than heritage rules do.
Hobart sits at the other end. It holds some of the oldest colonial housing in the country; heritage listings are dense; and cold-climate performance is usually the reason people renovate in the first place.
The Parts of the Process That Never Change
Wherever you are, the trade sequence holds. Services go in before linings, and linings go in before finishes.
Licensing and insurance checks apply nationally, even though the registering body differs by state.
Contingency is the other constant. Older homes carry more unknowns than new builds, so the sensible move is to commission a condition assessment before you set the budget rather than after.
Conclusion
The renovation sequence is national. The risk is local, and it is usually sitting inside the walls.
A Melbourne owner is planning around wiring. An Adelaide owner is planning around moisture and masonry. In both cases the first money spent should go on finding out what is actually there, not on choosing finishes.
Frequently Asked Questions
How much extra should I budget for renovating an older home?
More than you would for a new build, because more of the work is discovered rather than planned. A condition report before you finalise the budget is the best way to shrink that unknown.
Does a heritage overlay stop me renovating the interior?
Usually not. Overlays generally protect external elements such as the facade and roof form, while interiors are far less restricted. Confirm the specifics with your local council, because overlays vary between municipalities.
Do I need to rewire the whole house or just part of it?
It depends on the switchboard and the condition of the existing cable. A licensed electrician will assess both before recommending a partial or full rewire.
Should painting happen before or after fit-off?
Main coats go on before fit-off, with touch-ups afterwards. Painting a room that already has fittings installed takes longer and produces a messier finish.
