Knockdown-Rebuild Site Clearing in Ipswich
Your builder has a start date. Everything that decides whether you hit it happens weeks earlier — in the approval queue and the Energex abolishment, not on demolition day.
The sequence that actually governs your start date
Knockdown-rebuild customers consistently underestimate the front half of the project and overestimate the demolition.
Here is the real order of operations in Queensland:
1. Check your zone and overlays — the Property Report shows character, heritage, flood and any other overlay. Free, same day.
2. If an overlay applies, planning approval from council comes first. Your certifier cannot issue building approval ahead of it.
3. Engage a private building certifier for the demolition building approval.
4. Services abolished — and Energex requires written confirmation before any work starts.
5. Asbestos survey, with licensed removal where required.
6. Demolition and site clearing.
Steps 4 and 5 run in parallel with 2 and 3. Run them in sequence and you add a month for no reason.
Energex is your critical path
Worth repeating on this page because it is what actually delays knockdown-rebuilds:
Energex needs a supply abolishment, lodged by your retailer, taking around 20 business days. And demolition cannot start "under any circumstances" until Energex confirms in writing that the connection has been removed.
If you take one thing from this page: lodge the abolishment the day you commit to the project. Not when the builder's contract is signed, not when the certifier is engaged. Day one.
Where our scope ends and your builder's begins
This is where knockdown-rebuild quotes get argued over, so here is the line in plain terms.
Ours: the house, all demolition waste removed, site cleared, and the slab where slab removal is in scope.
Your builder's: the site cut to the engineer's levels, new footings and the new slab.
Two specific things to settle in writing before anyone starts:
Is the existing slab in the demolition scope or not? It is a real cost either way and it is the item most often assumed by both parties to be the other's problem.
What condition is the site handed over in? Cleared and level is not the same as cut to level.
Published figures for site preparation and clearing as an add-on range widely — roughly $1,000 to $2,500 at one end and $5,000 to $10,000 at the other. That spread is real and depends heavily on what is actually on the block, which is why we quote it after looking rather than as a line item percentage.
Springfield, Ripley and the growth corridors
Both sit under additional controls in Part 10 of the Ipswich planning scheme, separate from the general provisions. If your block is in either corridor, that is the first check — not the last.
Flood overlay shapes the rebuild
If your property sits in the Flood Risk and Overland Flow Overlay, the overlay governs minimum floor levels for the new house. That is a design constraint, and it is far cheaper to discover before your builder has drawn anything.
Ipswich revised its flood zoning to reflect the 2011, 2013 and 2022 events, so an older report may not reflect where your land now sits.
Pools, sheds and everything else on the block
A knockdown-rebuild rarely involves just the house. Pool removal in Queensland runs roughly $4,000 to $12,000 and up, and sheds, garages, carports, retaining walls and paving all carry their own scope and cost.
The useful thing is to price the whole block at once rather than discovering the pool after the house is down — which is when it becomes an expensive variation instead of a line in the original quote.
What it costs
Demolition for a knockdown-rebuild sits in the same band as any house demolition: $12,000 to $40,000, roughly $40 to $150 per square metre, with asbestos as the biggest single variable and Queensland's $125 per tonne metro waste levy feeding into disposal.
Against a full knockdown-rebuild project, demolition is a modest share of total cost — which is worth keeping in proportion when comparing quotes that differ by a few thousand dollars but not on what is actually included.

- Flood overlay floor-level implications flagged before design starts
Knockdown-Rebuild Site Clearing — common questions
How far ahead of my builder do I need to start?
Allow a comfortable margin, because the demolition is the short part. Energex supply abolishment alone runs around 20 business days and must be confirmed in writing before work starts. A Road Permit needs at least 20 business days. If a character, heritage or flood overlay triggers planning approval from council, that sits ahead of your building approval as well. The demolition itself is only two to five days.
Who arranges the demolition — me or my builder?
It varies by builder. Larger project builders often manage the whole sequence inside their contract; smaller and custom builders generally expect you to engage a demolisher directly. Either way, the approvals attach to your property and the electricity abolishment is lodged by your retailer, so you are in the loop regardless. We coordinate directly with your builder on dates once the scope boundary is agreed.
Is the existing slab removed, or does it stay?
It depends what you agree, and it is the single most disputed item in knockdown-rebuild quotes. Removing it is a genuine cost; leaving it can suit some rebuild designs and not others. What matters is that it is stated explicitly in writing in both our scope and your builder's, because when neither document mentions it, both parties tend to assume it is the other's problem.
What condition is the site left in?
Cleared of the structure and all demolition waste, and level — but note that cleared and level is not the same as cut to your engineer's levels. The site cut for the new slab sits in your builder's scope, priced against their engineering. Worth confirming that boundary with both parties before work starts so nobody is waiting on the other.
Do Springfield and Ripley have different rules?
Yes. Both growth corridors sit under additional planning controls in Part 10 of the Ipswich planning scheme, separate from the general provisions that apply elsewhere in the city. If your block is in either, that is the first thing to check rather than an afterthought — it can affect what approvals your project needs and how they are assessed.
How does the flood overlay affect a knockdown-rebuild?
It mainly shapes the rebuild rather than the demolition, by setting minimum floor levels for the new house. Ipswich lies on a floodplain and grades land across five risk bands, with zoning revised after the 2011, 2013 and 2022 floods — so an older report may not reflect current mapping. Establish this before your builder or architect draws anything, because it can materially change the design.
What happens to the pool and shed?
They should be in the original quote rather than discovered later. Pool removal in Queensland runs roughly $4,000 to $12,000 and up depending on construction and access, and sheds, garages, carports, retaining walls and paving each carry their own scope. Pricing the whole block at once avoids the classic problem where the pool becomes an expensive variation after the house is already down.
How much does knockdown-rebuild demolition cost?
The demolition sits in the same band as any house demolition: $12,000 to $40,000, or roughly $40 to $150 per square metre, with asbestos the biggest variable. Site preparation and clearing as an add-on ranges widely in published figures — from around $1,000 to $2,500 at one end up to $5,000 to $10,000 at the other — because it depends entirely on what is actually on the block.
