Knockdown rebuild · Beaconsfield
Short answer
Before you knock down and rebuild in Beaconsfield, check three things. First, your council: most of Beaconsfield is in Cardinia Shire and a small part is in the City of Casey. Second, your zone and overlays, from a free VicPlan planning property report. Most residential blocks aren't in the Bushfire Management Overlay, but some carry a vegetation, design, environmental, development plan or heritage overlay. Third, the demolition steps: report and consent, asset protection, asbestos and sewer assets. Turnkey Building Group (TKBG) is Victoria's leading builder broker, based next door in Berwick. We compare full turnkey, fixed-price packages from over 35 builders. We're paid by the builder from a share of its margin, so using us costs you nothing extra.
Why rebuild
Beaconsfield sits between Berwick and Officer, and it's a suburb of owner-occupied houses. At the 2021 Census, 86.3% of dwellings were separate houses and about 82% were owned outright or with a mortgage, both well above the Victorian figures.
New house lots are hard to find here. For many owners, the realistic way into a new home is to rebuild on the block they already have.
Beaconsfield station is on the Pakenham line. The Station Street level crossing was removed by building the McKenna Drive road bridge, which opened in March 2025. The Pakenham and Cranbourne lines are now boom gate free, and since 1 February 2026 they run exclusively through the Metro Tunnel. By road, the Beaconsfield interchange on the Princes Freeway is now a full diamond interchange. School zones go by address, so check yours with Find my School.
Council
Most of Beaconsfield is in Cardinia Shire, and a small part is in the City of Casey. Check which council your address is in first, because that decides whose planning scheme and demolition rules apply. Your rates notice or VicPlan report will show it. The demolition steps below are Cardinia's, so if you're in Casey, check with the City of Casey.
Overlays
Most of Beaconsfield's residential land is in the General Residential Zone. There are smaller pockets of Neighbourhood Residential Zone (around Glismann Road) and Low Density Residential Zone.
Overlays sit on top of the zone and can differ from one street to the next. Most residential blocks aren't in the Bushfire Management Overlay, which mostly covers the hills and green wedge land. Some streets do carry a Vegetation Protection, Design and Development, Environmental Significance, Development Plan or Heritage Overlay. Get a free planning property report from VicPlan before you pay for designs.
| Overlay | What it can mean for a rebuild | What to ask |
|---|---|---|
| Vegetation Protection (VPO) | Removing protected trees may need a permit, which can limit where the house goes | Which trees are protected? |
| Design and Development (DDO) | Its schedule can add design or siting requirements | What does the schedule require on my lot? |
| Environmental Significance (ESO) | Works may need a permit. Mostly on hills and green wedge land | Does it touch the house site? |
| Development Plan (DPO) | Development may need to follow an approved plan | Is there an approved plan for my area? |
| Heritage (HO) | Demolishing the house may need a planning permit | Is the existing house covered? |
| Bushfire Management (BMO) | A permit and bushfire protection measures may apply | What does it add to the design? |
Planning
Usually not. A single house on a lot over 300 m² in a residential zone generally doesn't need a planning permit under Clause 54. The siting rules are checked as part of the building permit instead. Clause 54 changed on 8 September 2025.
On a lot under 300 m², Clause 54 applies and you need a planning permit. An overlay can also trigger a permit on a bigger lot, which is why the VicPlan report comes first.
Planning Practice Note 84 says that in the General and Neighbourhood Residential Zones, a minimum garden area must be set aside when you build or extend on a lot of 400 m² or more:
| Lot size | Minimum garden area |
|---|---|
| 400 to 500 m² | 25% |
| Above 500 to 650 m² | 30% |
| Above 650 m² | 35% |
Garden area doesn't include the house (which counts a roofed alfresco, porch or verandah), the driveway or car parking. Only areas at least 1 m wide count. Lots under 400 m² are generally exempt. Check the rule before you settle on a big single-storey plan.
Demolition
Report and consent. In Cardinia you need Council's report and consent under section 29A of the Building Act 1993 to demolish a building, and a full knockdown needs it. You generally need it before your building surveyor can issue the demolition permit. Complete applications are generally processed within 15 business days. Heritage-registered buildings also need separate consent from Heritage Victoria.
Asset protection permit. Cardinia needs one before most works that could affect Council roads, footpaths, drains, nature strips or vehicle crossings, and demolition counts. Apply 28 days before works start. Work can't begin until the fee and refundable bond are paid and the permit is issued. It's valid for 12 months, and you apply for the bond refund within 7 days of finishing works, so photograph the nature strip before work starts.
Asbestos. WorkSafe Victoria requires any asbestos likely to be disturbed to be identified and, so far as reasonably practicable, removed before demolition starts. If you're not sure, assume it's there and have a sample analysed. A licensed asbestos removalist must do the removal. The only exception is limited non-friable removal: up to 10 m² in total and one hour in any seven days.
Sewer and water. Beaconsfield is in South East Water's area. You need its approval before building over its easement or within 1 m of its water, sewer or recycled water assets. Get the property sewer plan before the design is drawn.
Title. Check your title and plan of subdivision for covenants and easements.
Somewhere to live. You'll be out of the house from demolition to handover. Get each builder's estimated build time in writing and plan for longer.
The builder, demolisher, licensed asbestos removalist and building surveyor do this work, so book them in the right order.
What's new
On 17 November 2025, Cardinia approved the Glismann Road Area Development Plan. It covers land on Glismann Road, the Old Princes Highway and Mahon Avenue, where new subdivision can now happen. Landowners can apply for permits to subdivide or develop if their proposals align with the plan.
It allows conventional and medium-density lots on flatter land and larger Visually Sensitive Residential lots on steeper slopes. There are rules on retaining walls, earthworks and keeping vegetation. Nobody has to subdivide. If you own a newly subdivided lot there, you pay the Community Infrastructure Levy before a building permit is issued for a new house.
The broker
The risk is a design picked before anyone looks at the block. It can fail the garden area rule, sit over a sewer easement or clash with a protected tree, and then the "fixed" price moves.
Send us your VicPlan report and title. We shortlist designs from over 35 builders that fit your frontage, overlays, garden area and the assets on the lot. Then we compare full turnkey, fixed-price quotes priced on the real site. Our site costs guide and turnkey inclusions guide show what each quote should cover.
You choose the builder and sign the building contract directly with them. TKBG is a builder broker, not a builder. Before you sign, read how to check a builder in Victoria and how builder brokers get paid, or compare a broker with going direct.
If you'd rather buy land, compare Berwick, Officer, Pakenham or Clyde North. See builder broker Melbourne for how we work.
Why TKBG
Questions
Most of Beaconsfield is in Cardinia Shire, and a small part is in the City of Casey. Your rates notice or VicPlan report will tell you. If you're in Casey, check the demolition and asset rules with the City of Casey.
Usually not for a single house on a lot over 300 m² in a residential zone, where siting is checked with the building permit. Under 300 m², or where an overlay applies, you may need one.
Probably not. Most residential blocks in Beaconsfield aren't, because the overlay mostly covers the hills and green wedge land. Check your VicPlan report.
It's Council's consent to demolish under section 29A of the Building Act 1993. A full knockdown needs it, and in Cardinia you generally need it before a demolition permit is issued.
It can, if the lot is 400 m² or more and in the General or Neighbourhood Residential Zone. The minimum is 25% to 35% of the lot, depending on lot size.
Possibly. Cardinia approved the Glismann Road Area Development Plan on 17 November 2025. Landowners can now apply for permits to subdivide or develop, as long as their proposals align with it.
No. TKBG is Victoria's leading builder broker. We're paid by the builder from a share of its margin, so using us costs you nothing extra. We compare full turnkey, fixed-price packages from over 35 builders.
