About licensed building designers in Toowoomba
In Queensland, most building work valued over $3,300, including labour and materials, must be carried out by a contractor holding a QBCC licence of the right class. Some work needs a licence at any value, including plumbing and drainage, fire protection, building design and site classification.
A licensed building designer in Toowoomba holds a licence from the Queensland Building and Construction Commission (QBCC) that names the classes of work they may carry out. The licence has to be held by the business you sign with: a director's personal licence does not cover their company, and a licence in one class does not cover work in another.
TradesField reads QBCC and the Australian Business Register and lists every company with a building & interior design class in Toowoomba. Licence status is free to check. The Construction Background Report adds court, adjudication, ASIC and licence conduct records, graded A to E.

A listing is a record, not a recommendation.
TradesField brings public register records together so checking a contractor is quicker. It does not replace the authorities that keep them. Records can change after we read them, and a register can hold something we have not matched, so check licences, company status and court records directly with the QBCC, ASIC, the courts and the relevant state regulator before you rely on them, sign a contract or pay a deposit.
