Frequently Asked Questions About Home Extensions

  • How long does a home extension take?

    Most home extensions take between 3 to 6 months, depending on the size, complexity, and level of structural modifications required. Single-storey extensions are usually faster to complete, while second-storey additions and more intricate designs may take longer due to engineering requirements and council approvals. From day one, we provide a clear timeline, so you’ll always know what to expect at each stage of the project.

  • Do I need council approval?

    Yes, most home extensions require council approval to ensure compliance with local building codes and regulations. However, we take care of the entire approval process for you. Our team handles everything from Development Applications (DA) and Complying Development Certificates (CDC) to liaising with engineers and certifiers. This ensures your extension is approved smoothly without unnecessary delays or complications.

  • Can I live in my home during the extension?

    In most cases, yes, homeowners can continue living in their property while the extension is being built. Our team takes careful measures to minimize disruption, keeping construction areas secure and separate from your main living spaces whenever possible. However, for larger-scale projects—such as second-storey additions or major structural work—you may need to relocate temporarily for safety reasons. If that’s the case, we will discuss this with you well in advance so you can plan accordingly.

  • How much does a home extension cost?

    The house extension cost typically ranges between $150K to $500K+, depending on factors like size, materials, design complexity, and structural modifications. A single-storey extension is generally more affordable, while a second-storey addition or high-end finishes can increase costs. At Inner West Home Extensions, we offer fixed-price contracts, so you’ll know exactly what you’re paying—no hidden costs, no budget blowouts. We also provide a free consultation and quote, so you can get a clear idea of pricing before making any commitments.
