Your estimate sits within the typical range.
A full renovation is usually quoted per square metre, but the level (cosmetic versus structural) changes the figure dramatically. Old homes carry hidden costs, wiring, plumbing, stumps, that only appear once work starts.
Ways to save
- Separate must-dos (services, structure, waterproofing) from nice-to-haves and stage the cosmetic work if budget is tight.
- Do services (wiring, plumbing) while walls are already open, it is far cheaper than going back later.
- Compare a high-end renovation against a knockdown rebuild, sometimes rebuilding is better value.
How we estimate this
A full house renovation in Australia typically costs around $1,500 to $3,000 per square metre for a mid-range renovation in 2026, so a 150m² home is often $150,000 to $400,000. Cosmetic renovations cost less, high-end and structural work much more.

What a full house renovation costs in Perth
A full-house renovation in Perth is priced first on the scope, since it ranges from a cosmetic refresh of paint, floors and an updated kitchen and bathroom with nothing structural moved, through to a full gut that strips the home back and moves walls, re-roofs, rewires and replumbs, and the two ends differ enormously in cost. The house size in square metres and the number of wet areas then multiply the figure, so a large gutted home costs far more than a small cosmetic update.
Perth's common double-brick construction shapes the structural side, because moving or removing a wall in a double-brick home means cutting load-bearing masonry and installing a steel beam and props, which is more involved and costly than opening a timber-framed wall, so a layout change is a bigger job here. Chasing new plumbing and wiring through solid double-brick also adds labour. The dry Mediterranean climate means less moisture damage to repair than a humid city, though an older home may still need rewiring. The isolation of the WA market can add lead time for specialist finishes, and labour sits near the national average, with the many trades sequenced across the renovation.
A full-house renovation is major building work that must be done or overseen by a licensed builder, with a structural engineer where masonry walls move and building approval for structural or external change, in Western Australia under WA Building Services, and licensed plumbers and electricians for the services. For a Perth home, the clearest way to price a full-house renovation is by the scope, times the house size and wet areas, with double-brick wall removal a bigger structural cost.
