Acreage Home in Mentone, Bayside Melbourne
Acreage building is fundamentally different from suburban building. Bore water, on-site wastewater, bushfire compliance, unsealed access and a lot more distance to services all reshape the budget. The upside is space, quiet, and the ability to build the house most suburban blocks would not allow.

Council rules and overlays for acreage 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 acreage home in Mentone
Water source
No mains water means bore, rainwater catchment, or trucked delivery. Each has cost and reliability implications. Test the bore before you fall in love with the block.
Wastewater system
On-site wastewater (septic, AWTS, worm farm) has to be sized, sited and approved. Get a soil percolation test done early.
Bushfire Attack Level (BAL)
Every rural block has a BAL rating. BAL-19 to BAL-FZ changes wall construction, window glazing, roof spec and materially the build cost.
Acreage Home FAQs for Mentone
Do I need mains water on an acreage block?▾
Not necessarily. Many acreage blocks rely on rainwater tanks and bore water. However bushfire regulations often require a minimum dedicated firefighting water supply on top of drinking water.
What is a BAL rating?▾
BAL stands for Bushfire Attack Level. Every block in a bushfire zone has one, from BAL-Low to BAL-FZ (Flame Zone). Your rating dictates window glazing, wall material and roof detail.
Can I use a project builder on acreage?▾
Most project builders decline blocks outside their standard service radius. Custom builders and rural-focused builders are usually the right fit.
How much extra do site costs add?▾
Acreage site costs commonly run 20 to 40% higher than suburban site costs because of power, water, wastewater and access.
Can I build without planning consent on acreage?▾
No. Rural zones still require planning consent for a new dwelling. Some outbuildings under 40m² may be exempt.
