How Long Does House Demolition Take in Glen Waverley?

Monash is one of the busiest knockdown-rebuild municipalities in Melbourne, so we have this conversation constantly. Owners plan around the demolition date and are then surprised that the demolition is barely a week of a project measured in months. Here is where the time actually goes.

The machine work is days

On a standard single-storey Glen Waverley home with reasonable access, the physical demolition is typically two to three days. Add a day or so for slab and footing removal and a final clean-up of the site.

Double-storey and full-brick homes stretch that to four or five days. Large blocks with outbuildings, a pool, or extensive paving take longer, but still in days rather than weeks.

What actually governs this is not the size of the house so much as how fast material can leave the site. A narrow frontage, a shared or restricted driveway, street parking that limits truck access, or a battleaxe block all slow the job because trucks become the bottleneck.

The approvals set the real timeline

For most Monash sites the demolition itself requires consent, and where the building is over a certain age or covered by an overlay, that consent has to be obtained under Section 29A before a demolition permit can issue. Allow real time for council assessment.

Where a planning permit for the new dwelling or dwellings is involved, and in Monash it usually is for anything beyond a straight single replacement, that process runs on its own timeline entirely and frequently governs everything else.

Service disconnection is the usual culprit

If a demolition program slips, this is normally why.

Electricity, gas, water and telecommunications each have to be abolished, not merely turned off, and each provider runs its own process with its own lead time. Abolishment of a gas or electricity supply commonly takes many weeks from the date of application, sometimes longer, and there is no way to accelerate it.

Nothing can start until these are confirmed. A demolisher cannot safely take down a house with live services running into it, and no reputable contractor will try.

The lesson is simple: lodge the abolishment applications as early as you possibly can. They do not depend on your demolition consent being granted, so there is no reason to wait.

Asbestos, and where it sits in the order

An asbestos assessment should happen early, because the result changes the program. Homes across Mount Waverley, Wheelers Hill, Mulgrave, Oakleigh and Clayton built before the 1990s frequently contain bonded asbestos in eaves, wall sheeting, wet areas and sheds.

Where asbestos is present, licensed removal has to be completed before general demolition begins, and licensed work carries its own notification requirements. In practice this adds days to the on-site program and requires scheduling that cannot be compressed at the last minute.

A realistic shape

For a straightforward Monash site without heritage or unusual complications, a workable picture looks like this.

Weeks one to four are the active administrative phase: asbestos inspection booked and completed, demolition consent lodged, service abolishment applications submitted to every provider, dilapidation report arranged if neighbours are close, and any arborist assessment done where mature trees are involved.

Weeks four to twelve are largely waiting on council and the utilities. This is the window to finalise the builder, resolve soil testing, and settle anything that has to be known before slab design.

Once consent and disconnections are confirmed, mobilisation usually follows within a week or two subject to machine availability, and the on-site work runs about two weeks from fencing to a clear, level site.

Three months is a reasonable planning assumption for a simple site. Complications push it to six.

What you can overlap, and what you cannot

Almost all the slow items are independent of each other and can run simultaneously. Service abolishment, asbestos inspection, dilapidation reporting and arborist assessment do not need to wait for demolition consent or for each other. Owners who run these sequentially add months for no benefit at all.

The genuinely sequential items are short: protective fencing before anything else, asbestos removal before general demolition, and confirmed service disconnection before machines start.

The things that most often add time

Incomplete applications that come back for further information. Late decisions about salvage or strip-out after the program is set. Neighbours declining access for a dilapidation inspection, which needs working around rather than arguing over. Mature trees with protection requirements that were not identified early. And wet weather, which affects truck movements on soft ground more than it affects the demolition itself.

Pool and outbuilding removal generally adds days rather than weeks, but it should be priced and scheduled up front rather than added mid-job.

Plan backwards from the slow items

Treat the demolition date as the output of the approvals and disconnection dates, not as a fixed input. If you are still weighing knockdown-rebuild against renovating, the approvals window is the right time to settle it.
