Falling in love with your neighbourhood but running out of room is a familiar story across Dromana. Rather than sell up and move away from the bay, many families choose to extend the home they already have.
Why extend rather than move?
Moving house carries costs that rarely show up in the listing price: stamp duty, agent fees, removalists and the upheaval of leaving a street you know. Extending lets you keep your position near the foreshore, your school zone and your established garden while gaining the space your household actually needs.
Done well, a thoughtful extension can also lift the value of your property. A second living zone, an extra bedroom or a reworked kitchen tends to appeal strongly to Mornington Peninsula buyers, particularly on blocks within walking distance of the beach.
Popular types of extensions on the Peninsula
The right approach depends on your block, your budget and how you want to live. Common projects around Dromana include:
- Ground-floor additions that push out the back of the home for open-plan living, a butler’s pantry or a larger kitchen.
- Second-storey additions that capture views towards Port Phillip Bay or Arthurs Seat without eating into the yard.
- Granny flats and studios for extended family, teenagers or a home office.
- Garage and alfresco extensions that connect indoor and outdoor living for our long coastal summers.
On sloping blocks near McCrae and Safety Beach, a split-level or under-house extension can be a clever way to add a whole floor by working with the natural fall of the land rather than fighting it.
Planning and permits in the Mornington Peninsula Shire
Most extensions in Dromana need a building permit issued through a registered building surveyor, and many also require a planning permit from Mornington Peninsula Shire Council. Planning triggers are common near the coast, where overlays for significant landscape, vegetation protection or bushfire can apply.
It pays to check your title and planning zone early. Setbacks, site coverage limits, overshadowing rules and neighbourhood character provisions all shape what you can build, and understanding them up front avoids expensive redesigns later.
If your property carries a Bushfire Attack Level (BAL) rating, your extension may need to meet specific construction requirements around cladding, windows and decking. A local builder familiar with these controls will factor them in from the first sketch.
Building for a coastal climate
Salt air, coastal winds and moisture are constant companions in Dromana, and they punish poorly specified materials. Choosing corrosion-resistant fixings, quality aluminium or timber joinery, and durable external finishes protects your investment over the long term.
Where an extension meets the existing home, careful detailing keeps water out and helps prevent mould in wall cavities. Matching rooflines, brick colours and window styles also matters so the new work reads as part of the original house rather than an obvious bolt-on.
Energy efficiency and comfort
New building work must comply with the National Construction Code, including energy provisions assessed through NatHERS. While the 7-star standard applies to new dwellings, extending is a natural moment to improve insulation, glazing and orientation so the whole home stays cosier in winter and cooler through summer without heavy reliance on air conditioning.
North-facing glass to living areas, good cross-ventilation and eaves that shade summer sun all lift comfort while trimming running costs. These decisions cost little at design stage but pay you back for the life of the home.
Working with a registered builder
In Victoria, domestic building work above the statutory threshold must be carried out by a registered building practitioner, under a written domestic building contract, with domestic building insurance in place. This framework, overseen by the Victorian Building Authority (VBA), protects you if something goes wrong.
Extensions add a layer of complexity that new builds do not: your builder is joining new structure to old, often while you continue living on site. Experience with staging the work, managing dust and noise, and dealing with the surprises hidden inside older walls makes a real difference to how smoothly the project runs.

What extensions cost
Cost varies widely depending on size, complexity, site access and finishes, so treat any figure as a rough guide only. A single-room ground-floor addition sits at the lower end, while a full second storey with new bathrooms and a reworked kitchen sits well above it.
Sloping sites, difficult access and structural upgrades to the existing home can all add to the budget. The most reliable way to understand your numbers is a detailed quote based on your actual plans rather than a headline rate.
Getting started
Begin by writing down how you want to use the extra space and how long you plan to stay. A good builder will help you test those ideas against your block, your budget and the planning rules that apply in your part of the Dromana area.

Frequently Asked Questions
Do I need a planning permit for a home extension in Dromana?
Many extensions in Dromana require a building permit, and a planning permit is also often needed because of coastal, vegetation, landscape or bushfire overlays applied by Mornington Peninsula Shire Council. Whether planning approval is triggered depends on your property’s zone, overlays and the scale of the work. It is best to check your title and planning controls early, as they directly shape what you can build.
How long does a home extension take to build?
Timeframes vary with size and complexity, but design, documentation and permits commonly take several months before construction begins. The build itself might run from a couple of months for a modest single-room addition to considerably longer for a second storey. Coastal weather, council processing times and any surprises found in the existing structure can all affect the schedule.
Can I live in my home while it is being extended?
In many cases yes, particularly for ground-floor additions where the new work can be sealed off from your living areas. Larger projects, such as second-storey additions that open up the roof, may require you to move out for part of the build. Your builder should discuss staging, dust control and safety with you before work starts so you know what to expect.
Will an extension add value to my Dromana property?
A well-designed extension that adds functional space, such as an extra bedroom, a second living area or a modern kitchen, typically appeals to Mornington Peninsula buyers and can lift value. Quality of construction, how well the new work blends with the original home, and proximity to the bay all influence the return. It is wise to weigh the likely value against your budget and how long you plan to stay.
