House Demolition
Full knockdown of an existing house down to a cleared, level block, ready for your new build.

Every extension and renovation in Mandurah begins with demolition — the old rear rooms off, the kitchen stripped to brick, the bathroom back to frame and joists. Done as its own properly-scoped stage, it means your builder and trades start on a clean, measurable shell. Done as an afterthought, it's where budgets go to die.
Partial demolition and strip outs cover both ends of that range: structural work like removing a rear section or opening a wall, and internal strip outs where the building stays untouched and the fit-out comes out.
Taking half a structure down is more careful work than taking all of it down. The cut line between old and new gets marked off the plans, the section staying gets protected and propped where needed, and the roof and wall junctions are left weather-tight — because the family is often still living in the front half while the back half becomes a building site.
On Mandurah's older brick-and-tile homes that usually means saw-cutting brickwork to a clean edge rather than letting an excavator find its own line. On timber-framed and fibro places around Silver Sands and Halls Head, it means checking what the sheeting is made of before anyone cuts anything — pre-1990 fibro is asbestos until a test says otherwise, and confirmed asbestos is a licensed removal job. See the asbestos removal page for how that referral works.
Inside, the scope is everything that isn't structure: kitchen cabinetry, bathroom fixtures, wall and floor tiles, carpet and timber flooring, built-in robes, old ceilings. The room goes back to frame or bare brick, the waste is sorted and carted, and the space is swept for the next trade.
The order matters. Trades cap water, gas and power first; then the strip runs from fittings down to floor coverings so nothing that's staying gets wrecked on the way through. A single wet area is typically a one-to-two-day strip; a whole-house strip ahead of a major renovation runs longer and earns its own bin strategy.
Plenty of Peel jobs sit between a strip out and a full knockdown — keep the front, lose the back, clear the yard. If the plan takes off more than it keeps, price it both ways: past a certain point, a full house demolition and rebuild costs less than surgery. If the block also needs sheds, slabs or vegetation gone, fold site clearing into the same mobilisation.
The quote should name every element coming out, the exact cut line for any structural work, who handles disconnections, and what condition each surface is left in — to frame, to brick, to slab. Fixed price, tip fees included. Typical Mandurah ranges by job type are on the costs page.

The section coming off is separated from the section staying, with the cut line braced and weather-sealed so the remaining house stays sound and dry. It's the standard first stage of a rear extension: the old lean-to or sleep-out comes off, the block behind is cleared, and the builder starts on a clean edge. What matters most is agreeing the exact cut line, on the plans, before work starts.
Internal, non-structural strip outs — cabinets, tiles, fixtures, floor coverings — generally don't need a permit under the Building Act 2011 (WA). Partial demolition that removes structure, like a rear section or a load-bearing wall, is different and will usually need a BA5 demolition permit through the City of Mandurah or Shire of Murray. Our permits page explains where the line falls; confirm your specific job with the council before work starts.
Work in that area stops, the material gets sampled, and any confirmed asbestos is removed by a licensed removalist before general work resumes — that's a WA legal requirement, not a judgement call. In Mandurah homes built before 1990, wet-area walls, eaves and old vinyl floors are the usual suspects, which is exactly why suspect materials should be tested at the quote stage rather than discovered with trades already booked.
