Frequently Asked Questions

  • Do I need council approval for a home extension?

    Yes, most home extensions in Australia require council approval or a complying development certificate, depending on your location and the type of work. Extensions that alter the footprint of your home add new structures or significantly change external features generally need formal approval. Your builder can help guide you through the approval process, including supplying plans and documentation. Failing to get the correct permits can result in fines or future issues when selling the property, so it’s always best to confirm your obligations with your local council before starting.

  • Can I live in my home during a renovation?

    In many cases, yes—you can stay in your home during a renovation, especially for smaller-scale or staged projects. However, it depends on the extent of the work and which areas are being renovated. Kitchen or bathroom updates can be disruptive if no alternatives are available. Larger renovations may involve noise, dust and safety concerns that make living on-site impractical. Your builder will advise whether staying is feasible or recommend temporary relocation. Good planning, protective barriers and regular communication can minimise disruption if you decide to stay in the home.
