Frequently Asked Questions

  • How much does a home extension cost in Canberra?

    The cost of a home extension in Canberra varies depending on size, design complexity and the type of space being added. Single-room extensions are generally more affordable than multi-room or second-storey extensions, which involve additional structural work. Factors such as materials, access to the site and connection to existing services also affect pricing. A detailed assessment of the home and proposed design is essential for understanding realistic costs.

  • Do home extensions require council approval in Canberra?

    Most home extensions in Canberra require council approval, particularly if they change the footprint, height or structure of the home. Approval requirements depend on factors such as zoning, block size and proximity to boundaries. Planning approvals and building regulations are designed to ensure safety and compliance, so it is important to confirm requirements early to avoid delays once construction begins.

  • Can I live in my home during an extension?

    In many cases, homeowners can remain living in the home during an extension, although this depends on the scale and location of the work. Smaller extensions may cause limited disruption, while larger projects can affect access, noise levels and utilities. Understanding the build stages and planning ahead can help households manage day-to-day living during construction.

Designed to Grow With You

Home extensions need to do more than add square metres – they need to support changing needs over time. Well-planned renovations can also improve how existing spaces function, enhancing comfort, flow and everyday usability. Each project is carefully designed to suit how the home is used now and how it may be used in the future, whether that means extra living space, reconfiguring layouts or improving indoor flow. Attention is given to structure, finishes and integration so the updated areas feel purposeful rather than added on.


With a clear process and well-structured planning, the end result is a home that feels cohesive, practical and built to last. Get in touch to explore renovation and extension options that suit your home and lifestyle.
