Planning a new home, renovation or extension in Melbourne usually starts with the exciting questions.
How much space can we add?
Can we bring more light in?
Can we keep the period character and still create a modern family home?
Then comes the less glamorous but very important question:
Will council need to approve this?
For many homeowners, “council approval” feels like a foggy paddock of forms, rules, delays and neighbour concerns. But once you understand the difference between a planning permit and a building permit, the process becomes much easier to navigate.
And, importantly, easier to design for.
First: council approval is not always one thing
When people talk about council approval, they are often referring to a planning permit.
A planning permit gives permission to use or develop land in a particular way. In Victoria, a planning permit may be required for a new home, extension, renovation or additional dwelling, and it is issued by the local council. If your project needs a planning permit, it must usually be obtained before a building permit can be issued.
A building permit is different. It relates to whether the proposed building work complies with construction, safety and technical requirements under building legislation. In simple terms, planning asks, “Is this appropriate for this site and neighbourhood?” while building asks, “Can this be built safely and correctly?”
That distinction matters because some projects need both. Some may need only a building permit. Some smaller cosmetic works may not need either, depending on the scope.
When might a Melbourne home project need planning approval?
Every site is different, but planning approval may be triggered by things such as:
Building a new home
Adding a significant extension
Changing the external form of the house
Building on a small or constrained block
Working on a property affected by a heritage overlay
Changing how the land is used
Building a second dwelling or small second home
Creating overlooking, overshadowing or neighbourhood character impacts
Building in areas affected by special planning controls, such as vegetation, flooding, bushfire or neighbourhood character overlays
For Melbourne homeowners, overlays are often the approval trapdoor. You may look at your street and think, “Plenty of people have extended.” But your property may have a heritage, neighbourhood character or environmental overlay that changes what council needs to assess.
This is especially common in established suburbs where period homes, narrow blocks and mature streetscapes are part of the area’s value.
Planning permit vs building permit: the simple version
Here is the practical difference.

The key point: a planning permit does not mean you are ready to build. It means council has approved the development in planning terms. You will still generally need the building permit process before work begins.
Likewise, a building permit cannot usually override the need for a planning permit. The Victorian Building Authority notes that if a planning permit is required, it must be issued before the building permit.
Why good design helps the approval process
Council approval is not just paperwork. It is also communication.
A well-considered design can show council that the project has been properly resolved. It can explain how the home responds to the site, the street, the neighbours and the existing character of the area.
This is where an architect can add real value.
For example, on a period home renovation, the approval challenge is often not simply “can we make it bigger?” It is:
How do we retain the character that matters from the street?
How do we place the new work so it feels sympathetic rather than bolted on?
How do we bring in light without creating overlooking issues?
How do we improve liveability without overwhelming the original home?
How do we document the proposal clearly enough that council can assess it confidently?
Good design does not guarantee approval. Councils still assess projects against planning schemes, overlays and local policies. But a thoughtful design can reduce friction, avoid obvious objections and give the application a stronger planning story.
That is the quiet magic trick: not design as decoration, but design as evidence.
The common mistakes that slow homeowners down
Many approval delays happen before the application is even lodged.
1. Designing before checking the planning controls
This is the classic expensive detour. A homeowner falls in love with a concept, then later discovers a heritage overlay, height control, setback issue or overlooking concern.
The better approach is to check the planning constraints early, before the design becomes emotionally laminated.
2. Assuming neighbours have done it, so you can too
Nearby projects can be useful references, but they are not automatic permission slips. Their sites may have different dimensions, overlays, zoning, orientation or approval conditions.
3. Treating council as the enemy
Council planners are assessing whether the proposal fits the planning rules. A clear, respectful and well-documented application usually has a better chance than one that tries to bulldoze its way through the system.
4. Underestimating documentation
Council may ask for site plans, elevations, shadow diagrams, overlooking diagrams, neighbourhood character responses, heritage information or planning reports, depending on the project.
Incomplete documentation can trigger requests for more information, which can turn a simple timeline into a slow-moving possum in the roof.
5. Ignoring the building permit stage
Planning approval is not the finish line. Structural documentation, engineering, energy requirements and building compliance still need to be resolved before construction.
How long does council approval take?
There is no universal timeline. It depends on the council, the complexity of the site, whether further information is requested, whether neighbours object, and whether the application needs revisions.
Victoria’s planning system has been undergoing reform, including changes intended to streamline some residential approvals. Planning Victoria announced updated requirements for single dwellings and small second dwellings, with changes commencing from 8 September 2025.
That said, homeowners should still avoid assuming approvals will be quick. Build time into your project plan. A calm approval process is usually the result of early preparation, not optimistic calendar sorcery.
What should you do before speaking to council?
Before lodging anything, it is worth getting clear on four things.
1. Your property controls
Check zoning and overlays. These may include heritage, neighbourhood character, vegetation, flooding or other planning constraints.
2. The real project scope
Are you renovating within the existing footprint, extending, adding a second storey, building a new home, or changing the use of part of the property?
The more the external form changes, the more likely planning questions become.
3. The design priorities
Know what matters most. More light? Better connection to the garden? Preserving the façade? Creating private parent or guest zones? Improving resale appeal?
This helps the design respond intelligently rather than becoming a wishlist wearing a roof.
4. The likely approval pathway
An architect can help identify whether your project may need a planning permit, a building permit, specialist consultant input, or early council advice.
Where Mark MacInnis Architect can help
Mark MacInnis works with Melbourne homeowners who want thoughtful renovations, extensions and new homes that respond to the site, the brief and the character of the existing home.
For many clients, the value is not just in creating a beautiful design. It is in helping shape a project that can move through the approval process with fewer surprises.
That may include:
Reviewing the opportunities and constraints of the site
Designing with planning controls in mind
Preparing clear architectural documentation
Coordinating with relevant consultants where needed
Helping homeowners understand the difference between design ambition and approval risk
Creating a home that feels resolved, not just approved
Final thought: approval should shape the design, not shrink it
Council approval can feel like a barrier, but it is better understood as part of the project framework.
The best homes are not created by ignoring constraints. They are created by working intelligently within them, then finding the design opportunity hiding inside.
If you are planning a renovation, extension or new home build in Melbourne, the earlier you understand the approval pathway, the better your design decisions will be.
