Renovation and extension budget planner NSW

Bring the wider project costs into view before you commit to a renovation or extension. Add your own allowances and see what still needs confirmation.

This planner totals your inputs. It does not predict construction prices, property value, tax savings or approval eligibility. Avoid double-counting items already covered in your construction allowance.

No login or email required. The tool keeps your answers in this tab. Choose the optional review link to carry the summary to Contact SCE; nothing is submitted automatically.
