How Much Does a Renovation Cost in Perth in 2026?
Perth renovation costs in 2026 range from $20,000 for a laundry renovation to $500,000+ for a full
house transformation. Single-room projects typically sit between $20,000 and $75,000. Perth costs
run approximately 18% above the national average — driven by trade demand from the mining sector,
material freight premiums, and the 2024 engineered stone ban.

Why Perth Renovation Costs Are Higher Than the National Average
If you’ve looked up renovation costs and found numbers that seem lower than what you’re being
quoted in Perth — this is why.
Trade competition from mining and resources
Perth’s resources sector employs ~155,900 people — almost exactly the same as the
construction sector (~155,500)
Both compete for the same licensed tradespeople — plumbers, electricians, tilers
When mining projects are active, residential renovation trade rates rise and booking windows
extend to 10–16 weeks
Freight premium on materials
Most building products — tiles, tapware, cabinetry hardware, stone — distribute from Sydney or
Melbourne warehouses
Freight adds 8–15% to the cost of most materials compared to eastern state pricing
Custom imported items and premium appliances carry an additional premium and longer lead
times
The engineered stone ban — July 2024
Engineered stone (Caesarstone, Silestone, and similar products) is banned in WA from July
2024
Benchtops now use Dekton, porcelain, natural granite, or marble instead
These materials perform better in most applications — but cost $500–$2,000 more than
pre-ban equivalents
What this means
Use Perth-specific pricing, not national averages. A kitchen renovation budget that
works in Melbourne will not deliver the same outcome in Perth in 2026. The numbers in this guide are
based on actual Perth projects completed by House & Co in 2025 and 2026
What Makes a Renovation More or Less Expensive The Five Key Variables
1. The age of your property
Older Perth homes carry hidden works risk that newer properties don’t. Pre-1990 homes regularly
contain:
- Asbestos in wall and ceiling linings — licensed removal costs $2,000–$8,000 per room
- Galvanised steel supply pipes — replacement in a bathroom zone costs $3,000–$7,000
- Non-compliant electrical wiring — upgrade costs $800–$3,000 plus compliance certification
House & Co conducts a property assessment at every consultation. Likely hidden works are
discussed and built into the scope — not discovered as surprise variations after demolition.
2. Material selections
- Cabinetry: custom built-to-dimensions vs flat-pack — a $8,000–$20,000 difference in a kitchen alone
- Benchtop: laminate ($1,800–$3,000) vs Dekton or porcelain ($3,500–$6,000) vs natural stone ($4,000–$7,000)
- Tiles: standard 300×600mm format vs large-format 600×1200mm — 15–30% more to lay
- Tapware: entry fittings with 3–5 year warranties vs House & Co's standard 15-year to lifetime warranty specification
3. Structural changes
- Non-load-bearing wall removal: $5,000–$8,000 — building permit required in WA
- Load-bearing wall removal: $10,000–$15,000 — structural engineer report + permit required
- New alfresco structural addition: $8,000–$15,000 — council permit approval 4–8 weeks
- New bathroom or wet area where none existed: additional $8,000–$15,000 on top of renovation cost
4. Scope of the renovation
- Like-for-like replacement (same positions, same layout): lowest cost within each room type
- Full relayout with plumbing relocation: adds $3,000–$10,000 depending on slab cutting required
- Multi-room renovation: combining bathroom and laundry (shared plumbing wall) typically saves 10–15% on trades versus two separate projects
5. Contingency — the budget line most homeowners skip
| Property Type | Recommended Contingency | Why |
|---|---|---|
| Post-2000 home, never renovated | 8–10% | Low hidden works risk. Standard construction. |
| 1985–2000 brick veneer | 10–12% | Some galvanised plumbing risk. Older electrical possible. |
| Pre-1985 — first major renovation | 15–18% | Asbestos likely. Galvanised plumbing probable. Electrical may be non-compliant. |
| Pre-1960 character home | 18–22% | Highest risk. Asbestos almost certain. Original plumbing and electrical throughout. Possible termite damage |
Contingency not spent goes back in your pocket. Contingency needed but not budgeted stops the
project.

FREQUENTLY ASKED QUESTIONS
Frequently Asked Questions — Renovation Cost Perth
How much does a renovation cost in Perth in 2026?
Renovation costs in Perth range from $20,000 for a laundry renovation to $500,000+ for a full
home transformation. Single-room projects: bathroom $25,000–$50,000+, kitchen $30,000–$75,000+,
laundry $20,000–$35,000, ensuite $20,000–$40,000+, alfresco $15,000–$60,000+. Home extensions
start from $80,000. Perth costs are approximately 18% above the national average due to trade
demand from the mining sector, freight premiums on materials, and the 2024 engineered stone ban.
Why are renovation costs higher in Perth than other Australian cities?
Three reasons: Perth’s mining and resources sector competes with construction for the same
licensed tradespeople, pushing labour rates above eastern state equivalents; a freight premium of
8–15% applies to most building materials which distribute from Sydney and Melbourne; and the 2024
WA engineered stone ban has shifted benchtop specifications to Dekton, porcelain, and natural stone
— all costing more than the products they replaced.
What is included in a House & Co renovation quote?
House & Co provides fixed-scope quotes covering: 3D design before any work starts; all licensed
trades (plumber, tiler, electrician, cabinet maker, painter) coordinated under one agreement; all
materials specified in the quote; and project management. The price you sign is the price you pay.
Variations are only raised for client-initiated scope changes.
What contingency should I budget for a Perth renovation?
For post-2000 Perth homes: 8–10% above the quoted price. For 1985–2000 homes: 10–12%. For
pre-1985 homes in their first major renovation: 15–18%. For pre-1960 character homes: 18–22%.
Contingency not spent returns to you. Contingency needed but not budgeted can stop a project
mid-build.
Do I need a building permit for a renovation in Perth?
A like-for-like renovation — same room layout, same plumbing positions — does not require a
building permit. Structural work (wall removal, new openings), new wet areas, alfresco structural
additions, and home extensions all require building permits in WA. House & Co manages permit
applications as part of every project scope.
How long does a renovation take in Perth?
A laundry renovation: 2–3 weeks on site, 6–8 weeks total. A bathroom: 3–5 weeks on site, 8–12
weeks total. A kitchen: 4–8 weeks on site, 12–16 weeks total (cabinetry manufacture takes 4–6
weeks). An alfresco with permits: 14–20 weeks total. A home extension: 24–32 weeks total. In Perth’s
2026 trade market, key trades book 10–16 weeks ahead — start the consultation process early.
Does renovation add value to a Perth home?
Yes, in most cases. Bathrooms and kitchens consistently return more than their cost in Perth’s
inner and western suburbs. A $32,000–$42,000 bathroom renovation typically adds $40,000–$60,000
in value in suburbs like Cottesloe, Subiaco, and South Perth. Alfresco renovations perform strongly in
Perth given the climate. The full home case studies in our Case Studies section each achieved
approximately $500,000 uplift.
