Duplex Home in Curlewis, Bellarine Geelong
A duplex is two dwellings on one title, sharing a common wall. Done well it can turn a single subdividable block into two homes, one to keep and one to sell or rent. Done poorly it creates neighbour disputes, planning knock-backs and resale headaches.

Council rules and overlays for duplex home in this area
In Victoria, a new build generally needs a planning permit (where the local planning scheme requires one) and a building permit issued by a registered building surveyor. Overlays such as Bushfire Management, Heritage, Significant Landscape and Development Contributions can apply, and growth-area blocks may attract the Growth Areas Infrastructure Contribution (GAIC). Confirm current requirements with your local council and the Victorian Building Authority before finalising a design.
The 3 decisions that shape your duplex home in Curlewis
Torrens title or Community title
Torrens gives each dwelling its own separate title with no shared body corporate. Community title is faster to approve but creates ongoing common areas. Ask your builder which their design supports before you sign.
Party wall detail
Fire rating, acoustic rating and thermal separation of the shared wall is the single line item that separates a good duplex from a cheap one. Ask to see the exact wall specification in writing.
Driveway and services split
Each dwelling needs its own metered water, power and NBN connection. Confirm the site plan shows two separate service pits, not a shared one.
Duplex Home FAQs for Curlewis
Can I build a duplex on any block?▾
No. The zoning has to allow two dwellings and the block usually needs to meet a minimum frontage and area under the council development plan. Check the property's zoning at the VicPlan portal before you engage a builder.
Do I need separate titles for each side?▾
You need separate titles if you want to sell one side independently. This is called Torrens title subdivision and is done after Certificate of Occupancy is issued. Community title is faster but creates a shared common area.
How much more does a duplex cost than a single home?▾
A duplex is usually cheaper per square metre than two single homes because the shared wall halves the roof and foundation on that side. Total cost depends on inclusions and finishes.
Can I live in one and rent the other?▾
Yes. This is one of the most common duplex strategies. Keep the tax treatment clean by confirming the split with your accountant before construction starts.
What happens if my neighbour objects?▾
Councils give neighbours a formal representation period during the planning consent stage. Objections do not automatically stop a duplex, but they can trigger a panel hearing that adds months. A pre-lodgement chat with adjoining owners is worth the time.
