No we are not architects. Building designers and architects have very similar responsibilities however there is one main difference. For an Architect to legally be allowed to use that title in Australia they must be registered with the ‘Board of Architects’ in their state and have studied 5 years of architecture followed by 2 years of practical work finishing off with an oral and written test.
Many people don’t know that building designers can perform a similar scope of work to an architect. A building designer still needs to fully comply with the state building and planning regulations. For example in Queensland all building designers are required to hold professional indemnity insurance in order to maintain a building design license with the Queensland Building and Construction Commission (QBCC). A Building Design company carrying out work in Queensland without the Building Design licence from the QBCC is doing so illegally.
