Typical Renovation Costs in Perth (2026)
Perth sits approximately 18% above the national average for home renovation pricing, driven by tight trade availability and freight premiums on materials. Waitlists of 10–16 weeks on key trades are common.
| Project type | Estimated cost range |
| Bathroom renovation (basic) | $10,500 – $21,000 |
| Bathroom renovation (mid-range) | $21,000 – $36,750 |
| Kitchen renovation (standard) | $25,000 – $30,000 |
| Kitchen renovation (mid-range) | ~$40,000 |
| Full internal renovation | $80,000 – $300,000+ |
| Ground floor extension | From $250,000 |
| Second storey addition | $350,000 – $600,000+ |
Mid-range kitchen and bathroom renovations in Perth typically return 60–80% of their cost in added property value, per HIA data. A 15–20% contingency allowance is broadly recommended given current trade and material conditions.
What Documents You May Need
For a cash-out refinance or equity-based renovation loan:
- Recent payslips or tax returns (last 1–2 years)
- Bank statements (typically 3–6 months)
- Current loan statement and rates notice
- Builder quotes or fixed-price contract
For a construction or major renovation loan, lenders will also require:
- Approved council plans and building permits (where applicable under WA’s Building Act 2011)
- Fixed-price contract from a licensed WA builder
- Progressive payment schedule aligned with project milestones
Benefits of Renovation Finance
- Access funds at home loan rates, significantly cheaper than personal loan rates
- Potential to increase property value and rental yield
- Construction loan structures protect cash flow on large staged projects
- Options for owner-occupiers and investment properties
- Can be combined with a home loan refinance to improve your overall rate at the same time
Things to Consider Before Applying
Renovation finance is a flexible tool, but there are trade-offs to be aware of:
- A cash-out refinance increases your loan balance and repayments
- Construction loans involve more documentation than standard home loans
- Perth’s trade shortage can extend project timelines – factor this into your drawdown schedule
- Over-capitalising relative to comparable properties in your suburb can limit value recovery at sale
