How Long Does House Demolition Take in Balwyn?

When people ask how long a demolition takes, they are usually picturing the excavator. That part is quick. A standard house on a reasonable block is typically down in a matter of days.

The honest answer to the question is measured in months, because almost all of the elapsed time sits before anything is knocked over. Understanding where it goes is what lets you plan a build realistically instead of optimistically.

Approvals: the long pole

This is where the time goes, and in Boroondara more than most places.

A demolition permit through a registered building surveyor is relatively predictable. Section 29A report and consent from council is less so, because council has to consider it and respond, and that is not immediate.

Where a heritage overlay applies, and across Balwyn, Kew, Canterbury and Deepdene it very often does, a planning permit may be required too. That is a substantially longer process, and it can involve advertising and objections. Properties that are not individually significant frequently still sit within a precinct overlay, which catches a lot of owners out.

Realistically, approvals are the difference between a project that starts this quarter and one that starts next year. Our article on demolition permits in Boroondara covers what applies.

Service abolishment

This is the second timeline driver and the one most often left too late.

Disconnection is not abolishment. Abolishment means the supply is permanently removed back to the main, and it is done by the relevant authority or distributor rather than by the demolisher. Electricity, gas, water and telecommunications each have their own process and their own lead time, and they run independently of one another.

These can be applied for while approvals are still in progress, and doing so is the single most effective way to compress an overall program. Leaving them until approval is granted simply adds their lead time to the end of the approvals period rather than overlapping it.

Asbestos assessment and removal

Any Boroondara house built before 1990 should be assessed. If asbestos is present, licensed removal happens before general demolition, and it is its own scope with its own timeline, usually measured in days rather than weeks for a typical residential job.

The assessment itself is quick. What causes delay is discovering asbestos late, because it was assumed rather than checked, and having to stop and mobilise a licensed removalist mid-job. Our piece on asbestos in Boroondara homes covers what to expect.

The demolition itself

Once approvals are in hand, services are abolished and asbestos is dealt with, the physical work is fast.

Site setup, fencing and protection is generally a day. The structure itself typically comes down in one to three days depending on size, construction and access. Then footings, slabs, paths and driveways are removed, material is sorted and carted, and the site is left cleared and levelled. For a standard Balwyn house, allow around a week on site, give or take.

Larger homes, difficult access, extensive hard surfaces or significant tree protection requirements extend that.

What actually causes delays

In order of how often we see them.

Approvals not started early enough, or a heritage overlay discovered after the design was already committed. Service abolishment left until approvals came through, adding weeks to the end. Asbestos assumed rather than assessed, discovered on site. Significant trees on or near the site with controls nobody checked, which is covered in our article on protecting significant trees. And weather, which affects the machine days but rarely drives the overall program.

How to compress the timeline

Start the approvals process before the design is finalised, so you know what you are working with. Apply for service abolishment in parallel rather than sequentially. Get the asbestos assessment done early, so it is priced and planned rather than discovered. Check the heritage and tree position at the very beginning, not after committing to a builder's start date.

Those four things account for most of the difference between a smooth program and one that slips repeatedly.

The short version

The excavator work is about a week. The approvals, service abolishment and assessments in front of it are what set the real timeline, and in a heritage-heavy municipality like Boroondara they can dominate it entirely. Start them early and run them in parallel, and the overall program shortens dramatically without anything happening faster on site.
