## Before you hire an architect
_What to check when choosing this kind of trade (general guidance, not a claim about this business):_
- Trade and building licensing in Australia is set by each state or territory. Check the relevant regulator (e.g. NSW Fair Trading, QBCC in Queensland, VBA in Victoria) that the contractor holds a current licence for the work type and value before you hire.
- For larger residential building work, confirm the contractor carries the home-building / domestic-building insurance your state requires before you pay a deposit. It is what protects you if the work is left unfinished or defective.
- Ask to see a portfolio of completed work like yours, plus recent references you can contact.
- Check the credentials and registrations that matter for this work, and that they are current.
- Get a written, itemised quote with scope, assumptions and a staged payment schedule.
