In most cases, building a structure over 9m² (class 1A structure) will require both council approval and building certification.
This typically involves:
- Draftsman or building designer plans
- Soil testing
- Structural engineering
- Building certification
- Energy efficiency (and bushfire assessment if required)
- Council plumbing permit
These are essential steps to ensure your project complies with local regulations and allows us to provide an accurate build cost.
At C.J Carpentry & Construction, we can coordinate this entire process for you, or you’re welcome to begin the process yourself by organising your own plans if preferred.
Typical design & approval costs range from $10,000 – $20,000+, depending on the site, services (sewered or unsewered), and overall project complexity.
For smaller projects, these costs may be lower where reduced approvals or simpler certification is required.
Once plans are finalised, we’re able to provide a detailed and accurate quotation for your project.
