Why Build a Home Extension?

Our Home extensions in Canberra deliver more than extra floor space.

They provide a future-ready upgrade that lifts everyday comfort, increases property value, and adapts to how you live. Skip the stress and cost of moving; transform the home you already love to suit your lifestyle.


With a well-planned design, stay in your favourite neighbourhood while creating flexible zones to grow, work from home, and entertain in style.


Choose a Canberra home extension that blends seamlessly with your existing architecture and gives your family room to thrive.


Top reasons for considering home extensions in Canberra:


A cost-efficient alternative to moving: 

  • Avoid the high costs of stamp duty, agent fees, removals, and temporary accommodation. Extending your home can be significantly cheaper than buying a new property while still delivering the extra space you want.

Customised design for modern living: 

  • Tailor your extension to your lifestyle—an extra bedroom, a spacious family room, a home office, or an entertainer’s kitchen. You can design every detail to match your taste and functional needs.

Boost your property value: 

  • Well-designed extensions often deliver an excellent return on investment by increasing resale appeal and market price. Buyers are drawn to spacious, updated homes in established suburbs.

Minimal disruption to daily life: 

  • With the right planning and builder, you can continue living in your home during construction, avoiding the upheaval of selling and relocating. Builders experienced in Canberra extensions can stage works to reduce disruption.

Improved energy efficiency & comfort: 

  • An extension is an opportunity to upgrade insulation, install energy-efficient glazing, integrate solar panels, and improve overall comfort and sustainability, reducing long-term running costs.

Types of Home Extensions

There are many ways to expand your home, depending on your needs and property layout:


  • Single-storey extensions are ideal for adding extra living space, like a family room or larger kitchen
  • Second-storey additions create new bedrooms, bathrooms or even a private retreat without reducing outdoor space
  • Rear extensions can open up your home for indoor-outdoor flow, perfect for entertaining
  • Granny flats or self-contained studios are great for guest accommodation or rental income
  • Garage conversions offer a smart use of existing space, turning unused areas into offices, gyms or extra bedrooms


Each type can be customised to suit your home’s style and structure.

Custom Designs for Your Home Extension

Planning a home extension is an opportunity to improve how your home functions and feels, without the need to relocate. At Ozi Construction, we offer tailored solutions for home extensions in Canberra, with custom designs developed to meet the unique requirements of each household.


Our design process begins with an on-site consultation to understand your property layout, existing structure, and long-term goals. Whether you're after extra bedrooms, a larger kitchen, an open-plan living space, or a dedicated home office, we’ll guide you through every design decision. We take time to understand how your household lives and grows, so your extension integrates seamlessly and supports future needs.


As licensed builders familiar with Canberra's planning and development requirements, we ensure all designs comply with local council regulations and ACT building codes. From block limitations and energy efficiency standards to heritage overlays, our team takes care of the regulatory details for you.


Our designers work closely with engineers and project managers to translate your ideas into working plans that balance form and function. We consider lighting, ventilation, flow, and visual harmony with your existing home. Every detail—from window placement to rooflines and finishes—is chosen to enhance both aesthetics and practicality.


You’ll also have input on key design features such as materials, floor plans, and fittings to match your style and budget. Whether you're adding a second storey, building outwards, or transforming unused space, our team delivers professional guidance and craftsmanship from start to finish.


If you're exploring home extensions in Canberra that are built to last and designed around your lifestyle, we’re ready to bring your vision to life with smart, personalised solutions.

Frequently Asked Questions

  • How much does a home extension cost in Canberra?

    The cost of a home extension in Canberra depends on the size of the project, the design complexity, and the choice of building materials. On average, single-storey home extensions in Canberra start from $2,000–$3,000 per square metre, while double-storey extensions may cost more due to additional structural requirements. At Ozi Construction, we provide customised, obligation-free quotes to ensure your extension fits your budget, lifestyle, and property goals.

  • Will a home extension add value to my property?

    Yes, a well-designed home extension can significantly increase the value of your property by adding usable space, improving functionality and enhancing overall appeal—especially when tailored to meet modern living needs.

  • Is it cheaper to build a home extension or move house in Canberra?

    In most cases, extending your home in Canberra is more cost-effective than selling and buying a larger property. Extensions allow you to stay in your preferred suburb while adding space and increasing your home’s value without the high costs of stamp duty, agent fees, and relocation.

  • Do I need council approval for a home extension in Canberra?

    Yes. Most home extensions in Canberra require Development Approval (DA) or Building Approval (BA) through the ACT Government. Ozi Construction guides you through the approval process to ensure your extension complies with Canberra’s building codes and local regulations.

  • How long does it take to get council approval for a home extension in Canberra?

    Approval times vary, but most Canberra home extension applications take between 6–12 weeks. The timeframe depends on the complexity of your design and council assessment requirements. We assist you with all the paperwork to make the process smooth and stress-free.

  • Can I stay in my home during a Canberra extension project?

    In most cases, yes. Many homeowners continue living in their property while the extension is built. However, depending on the scope of work, there may be short periods where temporary relocation is recommended for safety and comfort.
