How Much Does a Full Home Renovation Cost in Melbourne in 2026?
If you are planning a full home renovation in Melbourne, one of the first questions is simple: what should the budget be? The honest answer depends on the size of the home, the condition of the existing building, how much the layout changes and the level of finish you choose. But there are useful planning ranges that can help you decide whether the project is ready to move forward.
For a professionally managed renovation involving several rooms, new services and a meaningful upgrade to the home, a realistic starting point is often around $150,000. More detailed whole-home renovations commonly move into the $200,000 to $300,000-plus range. If the project includes an extension, major structural work or high-end selections, the budget can rise beyond that.
These figures are a planning guide only, not a quote. The best way to protect your budget is to define the scope properly before construction pricing is locked in.
What is included in a full home renovation?
A full home renovation is more than replacing finishes. It can combine a new kitchen, bathrooms, laundry, flooring, painting, electrical and plumbing upgrades, cabinetry and changes to the layout. Some homes also need structural beams, new windows and doors, heating and cooling work, waterproofing upgrades or repairs uncovered during demolition.
The broader the scope, the more important it is to coordinate the drawings, selections and building work as one project. Pricing each room in isolation can miss the costs shared across the whole job, including site setup, demolition, waste removal, temporary protection, trade sequencing and compliance.
The biggest factors that affect renovation cost
Layout and structural changes. Moving walls, creating openings and extending the building require more documentation, engineering and construction work than retaining the existing layout.
Kitchen and cabinetry. Cabinet configuration, internal fittings, stone, appliances and custom joinery can make a substantial difference to the final price.
Bathrooms and wet areas. Waterproofing, tiling, plumbing changes, niches, custom screens and tapware selections all affect the budget.
Electrical, plumbing, heating and cooling. Older Melbourne homes often need service upgrades when several rooms are renovated together.
Windows, flooring and finishes. Material choice matters, but preparation and installation can be just as important as the product itself.
Access and existing conditions. Tight sites, limited parking, occupied homes and hidden defects can change how the work must be delivered.
Documentation and approvals. Measured drawings, design work, engineering, energy reports and permits may be required depending on the scope.
Why an early ballpark can change
An early ballpark is useful for testing whether a project is financially realistic. It is not the same as a detailed building proposal. Once the design is developed, the builder can measure the work properly, confirm inclusions and price the selections that have actually been made.
Budget changes often happen when items that were not included in the early discussion are added later: more cabinetry, upgraded stone, additional electrical work, premium tapware, window replacements, structural changes or work to rooms that were originally outside the scope.
A clear proposal should separate the base inclusions from optional upgrades. That allows you to make informed decisions instead of comparing headline prices that may cover very different scopes.
Do you need drawings or a building permit?
Many internal cosmetic renovations can proceed without planning approval, but structural work, extensions and significant layout changes usually need proper documentation and may require engineering and a building permit. Every property and scope is different.
Where drawings or specialist input are needed, Infinity Eight Building Group works with the appropriate designers, architects, engineers and consultants. Bringing the builder into the process early helps keep the design aligned with a realistic construction budget before too much time is spent documenting an unaffordable scheme.
How to keep your renovation budget under control
Set a realistic total budget, including a contingency for the unexpected.
Separate must-have work from items that can be staged or upgraded later.
Complete the drawings and engineering before relying on a fixed construction price.
Choose key finishes early, especially cabinetry, stone, flooring, tiles and tapware.
Ask for a detailed inclusions schedule so you understand exactly what is allowed for.
Avoid making major layout and specification changes after construction begins.
Staging can work well when the stages are planned together. However, splitting a job can also repeat costs such as site setup, protection, waste removal and trade mobilisation. It is worth comparing the saving in cash flow with the extra cost and disruption of returning later.
How Infinity Eight approaches a renovation
Infinity Eight Building Group is an owner-led Melbourne renovation builder. Daniel and Mark stay involved from the early conversation through planning, pricing and construction. Our process is designed to reduce uncertainty before work starts.
Initial conversation about the home, priorities, timing and budget.
Site visit to understand the existing conditions and discuss the proposed scope.
Drawings and consultant input where the project requires them.
Detailed proposal with clear inclusions, allowances and optional upgrades.
Selections, approvals, contract and construction planning.
Managed delivery with direct communication throughout the build.
We are not the right fit for every project. Our best work is with homeowners who want a considered renovation, clear communication and a builder involved early enough to help the design and budget work together.
Frequently asked questions
How long does a full home renovation take?
The construction period depends on the scope, approvals, material lead times and whether structural work is involved. A straightforward internal renovation may take several months, while a complex renovation or extension can take longer. A reliable program can only be prepared after the scope and documentation are clear.
Can we live in the home during the renovation?
Sometimes, but it depends on which services and rooms are affected. During a full-home renovation, living on site can slow the job and create safety, access and dust-control issues. This should be discussed during planning.
When should we involve a builder?
Ideally, before the drawings are completely locked in. Early builder input can identify cost risks, construction constraints and opportunities to simplify the project while the design is still flexible.
