Home building cost guide for Orange and regional NSW
These figures come from published guides, reviewed 28 October 2026. They are not Orange-specific and not quotes.
How to read the table
- Per m2 rows are rough guides
- Extension and granny flat figures are national or NSW-wide
- The new-home rows come from a modular builder's guide, so they may favour its own pricing
- Site costs, approvals and fees are usually extra
Local note
We did not find a published Orange-only price list, so no row claims to be local pricing.
