Frequently Asked Questions
What does a building designer do?
A building designer plans and prepares the drawings and documentation required for residential and commercial construction. This includes site layout, floor plans, elevations and technical detailing that comply with building codes and local council requirements. Building designers focus on functionality, aesthetics, sustainability and cost-efficiency — often collaborating with engineers, surveyors and town planners during the process.
Do I need council approval for building design?
Yes, most new homes, duplexes and renovations require approval before construction can begin. This usually involves either a Development Application (DA) through the local council or a Complying Development Certificate (CDC), which is a faster, private certification process. The right option depends on your zoning, lot size and design. A professional designer will help determine the best pathway for your project.
How long does the design and drafting process take?
The timeframe can vary depending on the project’s complexity, the number of revisions and council requirements. A basic design and drafting project may take 2–4 weeks, while more complex designs (such as duplexes or dual occupancies) may take 4–8 weeks or more. Council approval times are separate and can range from a few weeks to several months. Clear communication and planning help speed things up.
