Every design process is unique, and this generic step-by-step guide to the design process is indicative only. The number of steps varies depending on the complexity of the project and whether you’re building a new home, renovating, or simply making a few small home improvements. Regulation and registration of building designers also vary between states. Building designers are state-registered in Tasmania, Queensland, and Victoria. They are moving toward national accreditation in other states and territories through Building Designers Australia. NSW and South Australian chapter members are accredited through an internal process.
