Dual Occupancy in Point Cook, Western Melbourne
Dual occupancy is two dwellings on one title where the block is not subdivided. Common configurations are a house at the front and a smaller dwelling behind, or an upstairs-downstairs split. Cheaper and faster than a duplex-plus-subdivision, but it stays as one title so both sides sell together.

Council rules and overlays for dual occupancy 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 dual occupancy in Point Cook
Front-back vs stacked
Front-back needs a longer block and a shared driveway. Stacked (upstairs-downstairs) works on smaller blocks but the layout is more design-constrained.
Single title trade-offs
The block cannot be split. If you plan to sell one side to help fund the other, dual occupancy is the wrong structure. Look at duplex-with-subdivision instead.
Privacy and independence
Separate entries, private outdoor space and acoustic separation matter more than most owners plan for. Get the layout critiqued by someone who will actually live there.
Dual Occupancy FAQs for Point Cook
How is dual occupancy different from a duplex?▾
A duplex ends up as two separate titles. Dual occupancy stays as one title. You cannot sell one dwelling of a dual occupancy without selling the other.
Can I rent one dwelling and live in the other?▾
Yes. This is one of the most common dual-occ strategies, especially for aging parents or adult children.
Does dual occupancy add value?▾
Usually yes, but less per m² than a duplex-with-subdivision would. The market pays for optionality that dual occupancy does not deliver.
Can I convert dual occupancy to a duplex later?▾
Sometimes. It depends on whether the original design supports service separation and boundary compliance for a future subdivision. Get this planned in from day one if it is a possibility.
Do I need two street addresses?▾
Councils usually assign an A/B or 1/2 subaddress. This is functional but not the same as two separate titles.
