  • What should I consider before planning a home extension?

    Key considerations include your budget, intended use of the space, block size, structural limitations, and council regulations. It’s important to plan carefully to ensure the extension meets your needs without compromising the overall design and function of your home.

  • Do extensions require a building inspection?

    Yes, building inspections are required at various stages to ensure compliance with Australian Building Standards. These include inspections before slab pour, framing, waterproofing, and final completion. Certificates from licensed inspectors are often needed for approvals and insurance.

  • Will a home extension affect my property’s value?

    A well-executed extension can significantly increase your property’s market value and appeal to buyers. Added living space, extra bedrooms, or modern layouts enhance both comfort and resale potential. Quality workmanship and thoughtful design are key to maximising return on investment.
