It is important to use a registered architect because then you are certain that the person has attained the necessary qualifications, completed the specific practical experience, and has passed the Board’s examination before registration. Architects must undertake professional education appropriate to the services they provide which increases their professional competence and thus you are guaranteed a high delivery standard.
Architects are also subject to the Architects professional code of conduct in the Architects Registration Act governing their service to clients which ensures client protection even beyond the business/personal relationship. In case of misconduct, the architect is answerable to a regulatory body.
