The honest answer is that a renovation may add more, roughly the same or less market value than it costs.
That is not as satisfying as a promised “80% return”, but it is considerably more useful.
The value created by a renovation depends on the home, its condition, the local market, the work being completed and whether the finished result solves something buyers actually care about. A well-planned renovation can make a home easier to live in, more appealing to buyers and less expensive to maintain. A poorly targeted renovation can consume a large budget without producing the same increase in sale value.
Before you spend, the real question is not simply:
How much value will a renovation add?
It is:
Which improvements are worth making to this particular home—and what is the sensible limit?
Why Renovation ROI Percentages Can Be Misleading
You may have read that kitchen renovations return a particular percentage or that bathrooms produce a predictable increase in value.
Treat those figures cautiously.
There is no universal renovation return that applies across Melbourne. A new kitchen in a visibly dated family home may remove a major buyer objection. Replacing a perfectly functional three-year-old kitchen with a more expensive one may add very little.
The same renovation can produce different results in different streets, suburbs and property types.
Professional property valuation is based on relevant market evidence. The Australian Property Institute explains that the market approach compares a property with similar assets for which transaction information is available.
In plain English: recent comparable sales matter more than a generic percentage found online.
The Three Types of Renovation Value
A worthwhile renovation can create value in three different ways.
1. Market value
This is the additional amount a buyer may be willing to pay for the renovated home.
It is influenced by comparable sales, location, property type, bedroom and bathroom count, land, parking, condition and the standard buyers expect in that part of Melbourne.
2. Liveability value
This is the benefit you receive while living in the home.
Better storage, safer movement, improved lighting, an efficient kitchen layout and a properly functioning bathroom may materially improve daily life—even if every dollar spent is not immediately reflected in a valuation.
3. Avoided future costs
Renovating can address failing waterproofing, unsafe electrical work, deteriorated plumbing, poor ventilation or materials that will otherwise require attention later.
That work may not be visually exciting, but leaving it unresolved can become considerably more expensive.
A sensible renovation decision considers all three forms of value—not just the possible sale price.
How to Estimate the Likely Market Uplift
Start with evidence rather than finishes.
Ask two experienced local agents to estimate:
The home’s current value in its existing condition
The likely value after the specific renovation you are considering
Which existing features are holding the property back
What buyers in your area expect
The approximate price ceiling for comparable homes
For a major investment, consider obtaining advice from an independent property valuer.
Then review recent sales of genuinely comparable homes. Compare similar property types, land sizes, bedroom counts, locations and renovation standards. Do not compare an ordinary renovation with a substantially larger architect-designed home and assume the price difference came from the kitchen.
Use this calculation:
Estimated renovated market value minus current market value equals the potential market uplift.
Then:
Potential market uplift minus the complete renovation cost equals the likely financial surplus or shortfall.
A Simple Example
Imagine an unrenovated home is currently worth approximately $1.10 million.
Comparable renovated homes suggest a finished value of around $1.25 million.
That indicates a potential market uplift of approximately $150,000.
If the complete renovation costs $180,000, it has not produced an immediate resale profit—even though the home may be more comfortable, attractive and saleable.
If the owners intend to live there for another ten years, the liveability gained during that period may still justify the expenditure.
The calculation does not make the decision for you. It stops you making the decision based on a misleading assumption.
Use the Complete Renovation Cost
Do not compare the likely value increase with a cabinetry quote or showroom estimate.
Your complete project cost may also include:
Design, documentation and engineering
Permits, reports and professional fees
Demolition and waste removal
Plumbing and electrical work
Carpentry, plastering and painting
Cabinetry, benchtops and installation
Appliances, fixtures and fittings
Waterproofing and tiling
Flooring and lighting
Rectification of unexpected existing conditions
Builder coordination and project management
Temporary cooking or accommodation arrangements
Finance costs and a realistic contingency
This is why a kitchen advertised or quoted at one figure can become a much larger renovation once every required trade and surrounding repair is included.

What Usually Creates the Most Useful Value?
No single feature guarantees a return, but certain improvements are more likely to strengthen a home when they solve real problems.
Fix dysfunctional layouts
A renovation is more meaningful when it improves movement, usable bench space, storage, access or the relationship between rooms.
Moving everything is not automatically better. The aim is to make the layout work without introducing unnecessary structural, plumbing or electrical costs.
Remove obvious buyer objections
Failing waterproofing, visibly damaged finishes, unsafe work, insufficient storage and kitchens or bathrooms that no longer function properly can discourage buyers.
Correcting a genuine problem is generally more defensible than replacing something sound simply because a different colour is fashionable.
Improve the whole home coherently
A premium kitchen surrounded by visibly unresolved rooms can feel disconnected.
The best renovation budgets are allocated across the complete result: finishes, lighting, flooring, paintwork, transitions and the connected spaces people see and use.
Add practical storage
Storage rarely receives the same attention as decorative finishes, but it has an enormous effect on how a home functions.
The right amount depends on the household, appliances, pantry requirements and available floor area. Our guide explains how much kitchen storage you really need.
Improve comfort and running costs
Renovations also create an opportunity to improve insulation, draught sealing, efficient lighting, ventilation and water-efficient fixtures.
The Australian Government’s YourHome renovation guidance notes that careful renovation planning can improve liveability, thermal comfort and energy and water efficiency.
These benefits should not be treated as a guaranteed sale premium. They can, however, reduce ongoing costs and improve the experience of living in the home.
Kitchen or Bathroom: Which Adds More Value?
There is no universal winner.
A kitchen often influences how the broader home feels because it connects cooking, storage, dining and entertaining. In many family homes, a poorly planned kitchen is the larger objection.
However, a leaking, deteriorated or badly configured main bathroom can be the more urgent priority—particularly if it is the home’s only bathroom.
Renovate the room creating the greatest functional, condition or buyer problem. Do not automatically choose a kitchen or bathroom because an online percentage said it produces a better return.
If both require work, planning them together can produce a more coherent finish and reveal where the budget will have the greatest effect.
Renovating to Sell Soon
If you expect to sell within approximately three years, concentrate on removing obvious objections without designing the home for one highly specific taste.
Prioritise:
Necessary repairs
Functional layouts
Durable finishes
Neutral but considered selections
Good lighting and presentation
Consistency between rooms
Tight control of the complete budget
Do not assume the most expensive material will create the highest sale price. Buyers respond to the whole home, not the supplier invoice.
Renovating to Stay
If you intend to remain for five, ten or more years, the decision changes.
You have more time to benefit from improved storage, comfort, movement and appearance. Personal preferences become more reasonable because you will use the result every day.
You should still consider the local market and avoid unnecessary waste, but immediate resale return does not need to be the only measure of success.
A renovation can be financially imperfect and still be an excellent life decision. It should simply be made with clear expectations.
How Homeowners Overcapitalise
Overcapitalisation happens when the complete amount invested exceeds what the property and local market can reasonably support.
Common causes include:
Starting without an all-in project budget
Designing beyond the suburb’s realistic price ceiling
Selecting premium finishes before resolving the layout
Moving services without a meaningful functional benefit
Removing bedrooms, bathrooms, parking or valuable storage
Making highly personal choices throughout the entire home
Ignoring maintenance, approval or compliance issues
Comparing incomplete supplier quotes with complete builder proposals
Allowing small scope additions to accumulate during construction
Assuming that renovation expenditure automatically becomes property value
The solution is not to make every renovation cheap. It is to understand where spending improves the outcome and where it merely increases the invoice.
Five Checks Before You Commit
Before approving a major renovation, make sure you can answer these questions:
What is the home reasonably worth now?
What are comparable renovated homes actually selling for?
Which existing problems are buyers or occupants most likely to notice?
What is the complete cost of achieving the intended result?
Are you renovating primarily for resale, long-term use or a combination of both?
If those answers are unclear, choosing cabinetry colours is premature.
Plan the Renovation Before You Price the Dream
A useful renovation plan should establish:
The problems the renovation must solve
The sensible extent of work
Which existing elements can remain
The proposed layout and connected spaces
Likely trade, approval and documentation requirements
An initial all-in budget range
The major risks and unknowns
Where spending will have the greatest practical effect
Whether the project should proceed now, change direction or be staged
That planning is useful whether you ultimately build with Bluestone or decide not to proceed.
Turn the Evidence Into a Project Brief
Record the problems to solve, the complete scope, must-have outcomes, likely approvals and the all-in budget before comparing proposals. A shared brief makes omissions easier to see and gives each professional the same job to assess.
