How Much Does It Cost To Finish an Incomplete Build? (Melbourne Guide)
If your building project has been left incomplete, one of the biggest concerns is:
How much will it cost to finish?
The answer depends on several key factors.
What Impacts the Cost?
Stage of Construction
The further along the build, the less remaining work is required:
- Early stage → higher cost remaining
- Lock-up stage → moderate cost remaining
- Fit-out stage → lower cost remaining
Condition of Existing Works
The quality of work already completed has a major impact:
- Compliant works → lower cost (construction continues from where it left off)
- Defective works → higher cost (rectification required before continuing)
Rectification Requirements
Costs can increase significantly where:
- Waterproofing has failed or was incorrectly applied
- Structural issues exist
- Non-compliant works need to be removed and redone
Typical Cost Ranges
While every project is different, indicative ranges for Melbourne include:
| Scenario | Indicative Cost Range |
|---|---|
| Minor completion works | $20,000 – $80,000 |
| Mid-stage completion | $80,000 – $250,000 |
| Major completion + rectification | $250,000+ |
These are indicative ranges only. A site assessment is required to determine accurate costs.
Why Costs Can Increase
Builder takeover projects often cost more than initially expected because:
- Additional assessment and due diligence is required
- Previous works may need to be partially or fully removed
- The risk for the incoming builder is higher than a new build
- Documentation and permit reviews take time
Can Insurance Cover the Cost?
In some cases, yes.
If your builder has gone into liquidation, Domestic Building Insurance (DBI) may cover:
- Completion of works
- Rectification of defects caused by the original builder
Contact your insurer early to understand your entitlements. Read our related guide: What To Do If Your Builder Goes Bankrupt (Melbourne Guide).
How to Get an Accurate Cost
The only reliable way to determine the cost is to:
- Inspect the site and assess existing works
- Review plans, permits and documentation
- Identify defects and compliance issues
- Prepare a detailed scope of remaining works
- Provide a fixed-price cost to complete

Frequently Asked Questions
Is it cheaper to start again?
In some cases, but usually not. The cost of demolishing existing work and starting fresh often exceeds the cost of completing and rectifying. A full assessment is needed to determine the best path forward.
Can I get a fixed price?
Yes — after a full site assessment and detailed scope of works is prepared, a fixed-price contract can be provided.
How long will it take?
Timelines depend on the stage of construction, the extent of rectification required, and any permit or approval processes. A clear programme is prepared as part of the scope of works.
