These are indicative planning estimates, not a contractor quotation. Actual costs depend on site conditions, design, location, material specifications, labour rates and local approvals.

Most budget overruns come from items nobody priced at the start. Check each of these against your contractor’s quotation. Whether and how much each applies depends on your plot, city and design.
Before construction
- Architect and structural engineer fees
- Building plan sanction and local authority charges
- Soil testing and surveying
- Site clearing, levelling and temporary connections

How to protect yourself
Ask each contractor for a written list of inclusions and exclusions, compare them line by line (see comparing quotations), and keep a contingency. The main calculator also lists the exclusions it does not price.
