Frequently Asked Questions
How much does a home extension cost in Australia?
The cost of a home extension in Australia depends on the size, design, materials, and structural complexity of the build. On average, single-storey extensions typically range from $2,000 to $4,000 per square metre, while double-storey extensions can cost between $3,000 and $5,000 per square metre.
Factors such as demolition work, plumbing or electrical changes, and site access can significantly affect the final cost. For example, adding a bedroom and ensuite might cost around $80,000 to $120,000, while a larger open-plan living extension could be well over $150,000. It’s also important to budget for permits, approvals, and design fees.
Do I need council approval for a home extension?
In most cases, yes — council approval or a complying development certificate (CDC) is required for home extensions in Australia. Approval ensures your extension complies with zoning regulations, building codes, heritage restrictions, and setback requirements. Factors such as the extension’s size, height, location on the property, and impact on neighbouring properties will influence whether development consent is needed.
If your extension falls under exempt development, such as minor alterations with minimal impact, formal approval may not be required — but it’s essential to confirm with your local council or private certifier before starting any work.
Can I live in my house during a home extension?
Yes, it’s often possible to live in your house during a home extension, especially if the work is contained to one area of the home. However, this depends on the scale and nature of the extension. Larger projects involving structural changes, second-storey additions, or plumbing relocations may cause significant noise, dust, and temporary disconnection of services, making it more practical to move out for part of the build. Living on-site can help reduce accommodation costs, but it’s important to weigh this against comfort, safety, and how long the work will take.
