Whole Home Renovations
Whole Home Renovations near you
A whole-home renovation takes the entire house at once: every room stripped back, the plan redrawn, the services renewed and the finishes replaced, often with part of the building demolished and rebuilt. In Australia it is most often done to a small older house on a good block — a worker's cottage, a Federation semi, a post-war brick veneer, a Queenslander with unused space underneath — where the location is worth keeping and the layout is not.

Doing everything at once changes the regulatory picture rather than just the size of the invoice. The contract will be one of the larger prescribed forms your state requires, with a progress payment schedule and residential builders' insurance behind it. The approval will almost certainly be a full development application or its state equivalent rather than a fast-track pathway. And once enough of the building is new work, the energy efficiency provisions that apply in your state start to shape the design.
Those energy rules are the part most people do not expect, because they are not national. Each state and territory decides when and how it adopts each edition of the National Construction Code, and the ABCB's own adoption table shows the housing energy efficiency provisions of NCC 2022 commencing on different dates in different jurisdictions — and not being adopted at all in some. New South Wales runs its own scheme instead. Find out which applies where you are before the drawings are finished.
The common shapes a whole-home renovation takes in Australia
Builders price these very differently, and knowing which one you are describing is the difference between comparable quotes and a shortlist you cannot read. The distinguishing question in each case is how much of the existing structure survives.
- Back-to-frame internal rebuild: the external walls and roof stay, everything inside comes out, and the house is re-serviced, re-lined and re-fitted throughout.
- Rebuild with reconfiguration: internal walls move, so structure, an engineer and a building approval come in alongside the fit-out.
- Keep the front, rebuild the back: common where a heritage or character control protects the street elevation but not the rear, which is demolished and replaced.
- Raise and build under: a Queensland and northern New South Wales tradition, lifting a timber house on stumps to create a new legal storey beneath it.
- Full apartment or unit refurbishment, where the body corporate, common property and building fire and acoustic separation constrain what can change.
- Renovation combined with a second dwelling or a subdivision, which is a planning project first and a building one second.
When a renovation is large enough to be assessed like a new house
Past a certain point the approval authority stops treating the job as a modification and starts asking the questions it would ask of a new dwelling: setbacks, height, overshadowing, private open space, stormwater, car parking and energy performance. Where that point sits varies by state and by council, which is why the first conversation on a whole-home renovation should be with the council or a certifier rather than with a builder.
Energy performance is where the differences between jurisdictions are sharpest. The ABCB's adoption table for NCC 2022 records the housing energy efficiency requirements commencing in the Australian Capital Territory from 15 January 2024, in Victoria from 1 May 2024, in South Australia from 1 October 2024 and in Western Australia from 1 May 2025, with the Northern Territory adopting five-star requirements from 1 October 2023, Queensland deferring to its own Modern Homes timeline, and Tasmania not adopting the NCC 2022 housing energy efficiency requirements at all. New South Wales applied its enhanced BASIX scheme from 1 October 2023 instead, and the NSW Planning Portal says a BASIX certificate is needed for renovations of fifty thousand dollars or more — a figure any whole-home project passes.
The Code itself also moves on. The ABCB's adoption information for NCC 2025 shows jurisdictions taking it up on their own dates — 1 May 2026 in Victoria, Western Australia and the Australian Capital Territory, 1 May 2027 in New South Wales, Queensland and Tasmania, a split date in South Australia, and not adopted in the Northern Territory. On a project that spends a year in design, that means asking which edition your approval will be assessed under, not just which one is current today.
The order a full-house renovation is built in, and when you have to move out
Almost every whole-home renovation requires the household to leave, usually for months rather than weeks, because the power, water and drainage are all off at some stage and the dust from a full strip-out goes everywhere. Budgeting for somewhere to live, and for storage, is part of budgeting for the job rather than an afterthought.
LokalMatch is where the project starts for a lot of owners: you describe the house, the scope and the postcode once, and builders working in that area contact you. They pay for the requests they receive, which funds the service. LokalMatch does not carry out or price the work and does not vet, rank or endorse any business, so the licence check on your state's register, the insurance certificate and the reference calls are still yours to make.
- Measured survey and condition report of the existing house, including a hazardous materials survey where the building predates the late 1980s.
- Design and documentation, resolved far enough that the energy or BASIX commitments and the structural scheme are settled before lodgement.
- Planning approval, then building approval, with the certifier or building surveyor appointed by you.
- Site establishment, temporary fencing, waste management and disconnection of services.
- Demolition and strip-out, then any asbestos removal by a licensed removalist where required.
- Structural stage: new footings, beams, framing and roof, followed by the engineer's and certifier's inspections.
- Rough-in of plumbing, electrical, gas and mechanical services, then insulation, waterproofing and linings.
- Fit-out, fit-off, external works and landscaping, then final inspection, the occupancy or completion certificate and the handover of every compliance certificate.
Where the money goes on a whole-house project
On a job this size the finishes are a smaller share of the total than most owners expect, and the invisible work is a larger one. These are the items that most often separate two quotes for what looks like the same house.
- Demolition and waste removal, which on a full strip-out is a genuine line item rather than a rounding error, and rises again where asbestos is present.
- Structural remediation of what is found once the linings are off: footings, stumps, rotted or termite-damaged framing, and roof structure.
- Complete renewal of services, including a new switchboard and submains, re-piping, new drainage and, where they exist, gas alterations.
- Meeting current energy and thermal performance requirements through glazing, insulation, sealing and hot water, which are design decisions more than shopping decisions.
- Professional fees: architect or building designer, structural engineer, energy assessor, surveyor and the certifier or building surveyor.
- Temporary accommodation and storage for the household, and the fact that a long programme is exposed to price movement in materials.
- Site constraints: access for machinery, tight boundaries, slope, protected trees and the need to protect a retained heritage facade during demolition.
- Contingency for the things a strip-out reveals, which on an old house is not pessimism but arithmetic.
Heritage controls, hidden structure and services at the end of their life
Older Australian houses were built in eras with different expectations and different materials, and a whole-home renovation exposes all of them at once. The three that most often reshape a project are a heritage or character control that limits what may be demolished, a structure that turns out not to be capable of carrying the new plan, and services that have simply reached the end of their working life.
- Heritage listings and character or neighbourhood overlays, which can protect a street elevation, a roof form, a verandah or even the original room layout, and which are found in the planning controls rather than on the title.
- Stumps, bearers and joists in a raised timber floor that have moved, rotted or been attacked by termites, which is normal in houses of that age and abnormal only if nobody allowed for it.
- Masonry walls with no damp-proof course, or one that was bridged decades ago by a path or a garden bed built up against the wall.
- Wiring, switchboards and metering that cannot support a modern electrical load, particularly where induction cooking, air conditioning and vehicle charging are all being added at once.
- Drainage laid in materials and to falls that predate the current standards, which matters as soon as wet areas move.
- Asbestos in eaves, wet-area sheeting, roofing and vinyl floor backing in houses of the relevant era, which has to be identified and removed under licence rather than found mid-demolition.
- Long programmes drifting: on a project of this length, delays compound, so the contract's dates, extension-of-time clauses and progress claim triggers deserve careful reading.
Progress payments and builders' insurance on a large domestic contract
On a job of this size the contract is one of the larger prescribed residential forms your state requires, and the payment schedule is the mechanism that protects you. Payments should be tied to completed, verifiable stages — base, frame, lock-up, fixing, completion is the traditional set — and each claim should be checked against what is actually built before it is paid. Paying ahead of the schedule is the common thread in most homeowner losses, because money paid early is money you no longer control.
Residential builders' insurance stands behind the contract, and the trigger is the value of the work. In New South Wales, icare says cover is required by law for most residential building work valued at more than twenty thousand dollars unless an exemption applies, and that the builder must give you evidence of cover before work starts or you pay any further money under the contract, including a deposit. Queensland, Victoria and Western Australia run their own schemes with their own names and thresholds. Confirm which one applies, and hold the certificate before the first payment.
The certificates you collect at the end are worth as much as the finishes. Electrical and gas compliance, plumbing and drainage compliance, termite management, waterproofing, the energy or BASIX certificate and the occupancy or completion paperwork together form the record that the house was built to the approval it was granted. A purchaser's conveyancer will ask for them, and so will an insurer after a claim.
Renovating the whole house compared with knocking it down and rebuilding
Once a whole-home renovation involves new footings, a new roof and complete re-servicing, the comparison with demolishing and building new becomes a real one rather than a rhetorical one. The honest answer differs by site. Renovation keeps what is already there — a mature garden, an established street presence, a heritage facade, a floor level that suits the land — and avoids the planning exposure of proposing an entirely new building on a constrained block. It also keeps the parts of the house you cannot test until you open them up.
A new build starts from a known quantity and is designed against the current Code from the outset, which can make energy and livable housing requirements easier to satisfy than retrofitting them into an existing shell. Against that, demolition is not automatic: a heritage listing, a character overlay, a protected tree or a planning control on replacement dwellings can make it the slower path, and in some suburbs the impossible one. Ask the council what is permissible on your specific lot before letting the arithmetic decide.
Signs a house is a candidate for a whole-home renovation rather than a staged one
- The rooms you want to renovate are on both sides of walls you want to move, so no room can be finished independently of the others.
- The switchboard, the drainage and the water service all need renewal, which means opening the same walls and floors twice if the work is staged.
- The house has to be vacated anyway, which removes the main advantage of doing the work room by room.
- The layout, rather than the condition, is the problem — a small number of large changes fix more than a long series of small ones.
- The building predates the eras of insulation, sealing and modern glazing, so thermal performance can only really be addressed all at once.
- A hazardous materials survey shows asbestos in multiple locations, making a single controlled removal cheaper and safer than several.
- Your state's approval pathway would require a development application either way, so staging buys no regulatory simplicity.
Whole Home Renovations: frequently asked questions
Will a whole-home renovation have to meet current energy requirements?
That depends on your state and on how much of the building is new work. Adoption of the National Construction Code is a state decision, and the ABCB's adoption table for NCC 2022 shows the housing energy efficiency requirements starting on different dates across the country — the ACT from 15 January 2024, Victoria from 1 May 2024, South Australia from 1 October 2024, Western Australia from 1 May 2025, the Northern Territory with five-star requirements from 1 October 2023, Queensland deferred to its Modern Homes timeline and Tasmania not adopting them. New South Wales applies its enhanced BASIX scheme instead. Ask your certifier or building surveyor which requirements your approval will be assessed against.
Do I have to move out?
Almost always, and usually for months rather than weeks. Power, water and drainage are disconnected at some point, the strip-out generates dust throughout the building, and a full-house programme has trades working in every room. Treat temporary accommodation and storage as part of the project budget, and agree in advance what access you will have to the site while work is under way.
Is it cheaper to knock down and rebuild?
Sometimes, and it depends far more on the site than on the arithmetic. A rebuild is designed against the current Code from the start, which can make energy and accessibility requirements simpler to meet. But demolition is not always permitted: heritage listings, character overlays, protected trees and planning controls on replacement dwellings all constrain it, and an approval for a new dwelling may be slower and less certain than one for a renovation. Ask the council what your specific lot allows before comparing prices.
How should progress payments be structured on a large renovation?
Against completed, verifiable stages, in the form your state's prescribed contract requires, with each claim checked on site before it is paid. The traditional stages are base, frame, lock-up, fixing and completion. Never pay in advance of the schedule and never pay for work that has not been done — on a long programme, money paid early is money you can no longer use to have the work finished by someone else if things go wrong.
What insurance should the builder have before we start?
Residential builders' insurance where the value of the work requires it, plus their own public liability and contract works cover. In New South Wales, icare states that cover under the Home Building Compensation Fund is required by law for most residential building work valued at more than twenty thousand dollars unless an exemption applies, and that you must be given evidence of it before work starts or before you pay any further money, including a deposit. Queensland, Victoria and Western Australia run their own schemes with their own thresholds.
Which edition of the Code will my project be assessed under?
Whichever edition your jurisdiction had adopted when the application was made, and the dates differ. The ABCB's adoption information for NCC 2025 lists Victoria, Western Australia and the ACT taking it up from 1 May 2026, New South Wales, Queensland and Tasmania from 1 May 2027, South Australia on a split date, and the Northern Territory not adopting it. On a project that spends a year in design, that is a question worth asking your certifier at the start rather than discovering at lodgement.

What affects the cost of whole home renovation
Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:
- Size and scope of the project
- Structural changes, such as moving or removing walls
- Plumbing, electrical and HVAC work involved
- Finishes and materials chosen
- Design, drawings and permits
- Condition of the existing house once it's opened up
- Access to the site and the timeline
How to compare general contractors before you hire
- Look for a contractor who has finished projects similar in size and type to yours, and ask to see them.
- Get a written contract with the scope, the payment schedule, the timeline and how changes will be priced.
- Ask who will manage the job day to day and how often you'll get updates.
- Check that they carry liability insurance and workers' compensation coverage, and that their trades are licensed where required.
- Compare quotes on the same scope, and ask what each one leaves out.
- For structural changes, make sure an engineer or designer is involved where needed.
Questions to ask general contractors before you hire
- Who will pull the permits, and who will be there for inspections?
- Which parts of the job will you do yourselves, and which will go to subcontractors?
- How do you handle change orders and unexpected problems once walls are open?
- What is the payment schedule, and what is each payment tied to?
- Can you show me proof of liability insurance and workers' compensation coverage?
- What warranty do you offer on your workmanship, and is it in writing?
- Can I speak with a few of your recent clients?
Whole home renovation permits and local rules
Some whole home renovation work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
