How Much Does House Demolition Cost in Monash?

Demolition is one of the few parts of a knockdown-rebuild where the price genuinely varies from house to house, which makes it hard to budget from a web search alone. Here is a realistic picture for Glen Waverley and the wider City of Monash.

The headline numbers

For a standard three-bedroom Melbourne home, demolition generally falls between **$15,000 and $35,000**. Double-storey and full-brick homes push toward **$40,000**, and difficult sites can reach **$50,000**. Measured per square metre, most residential demolition lands somewhere around $40 to $105 depending on construction and access.

Against a total knockdown-rebuild commonly running $450,000 to $900,000, demolition is a small share of the project. It is also one of the easiest lines to underestimate.

What actually drives your number

Asbestos

This is the biggest single variable and the most common source of cost variations. Anything built before 1990 should be assumed to contain asbestos until inspection proves otherwise. Removal must be done by licensed operators before general demolition begins, and disposal must go to an EPA-approved facility. The quantity and whether it is bonded or friable both matter.

Site access

A wide Monash block with a straight driveway is cheap to work. A deeper block near central Oakleigh with a single side access, overhead wires and no street parking is not. Access determines machine size, how waste leaves the site, and how many days the job takes.

Concrete volume

People budget for the house and forget the driveway, paths, paving, garage slab and old extension footings. Concrete is heavy, and disposal is priced by weight. A large paved site — common on Wheelers Hill blocks — can add meaningfully to the total.

Pools

Removing a concrete pool shell and backfilling and compacting the void is a substantial job in itself. Some rebuild designs allow a pool to stay, which avoids the cost entirely — worth checking with your designer before assuming it has to go.

Heritage requirements

A Heritage Overlay can require a planning permit before demolition is approved, and may mean retaining a facade rather than a clean full demolition. This is more likely around older Oakleigh pockets than the outer Monash suburbs, but it is always address-specific.

The variations that catch people out

Most unpleasant surprises trace back to a quote given without a proper inspection. The recurring ones are asbestos that was never assessed, footings and slabs that were excluded from the scope, service abolishment costs treated as someone else's problem, and access limitations discovered on day one.

A fixed price issued after a site inspection is worth more than a lower estimate given over the phone. The second number is not really a price — it is an opening position.

Getting a number you can budget around

Get the inspection done early, while your design is still settling. It gives you a reliable figure to build the rest of your budget around, and it surfaces approval issues — overlays especially — at a point where they are still cheap to work around.
