Adding an extension to your home is a popular way to create more space, improve functionality, and even increase the value of your property. Whether you’re adding a new bedroom, extending your kitchen, or creating a multi-level addition, a home extension can transform the way you live. However, one of the biggest questions homeowners face when considering an extension is: “How much will a home extension cost?”

The cost of a home extension depends on various factors, including the size of the extension, the materials used, and the complexity of the project. In this blog, we’ll explore the different factors that affect the cost of a home extension, give you a rough idea of what you can expect to pay, and provide insights into how to maximise your investment.

Factors That Affect the Cost of a Home Extension

  1. Size and Complexity
    The size of your extension is one of the most significant factors in determining cost. A larger extension will require more materials and labour, increasing the total cost. Additionally, the complexity of the design plays a role. A straightforward ground-floor extension may be more affordable than a second-story addition that involves structural changes to your home.
  2. Materials Used
    The choice of materials can significantly impact the overall cost. High-end finishes, such as hardwood flooring, marble countertops, or custom cabinetry, will drive up expenses. On the other hand, opting for more affordable materials like laminate or standard tiles can help keep the budget in check.
  3. Labour Costs
    Labour costs vary depending on your location and the expertise of the builders you hire. In cities like Melbourne, labour can be on the higher end, but finding reputable and experienced builders ensures quality work that may save you money in the long run.
  4. Permits and Regulations
    Depending on the type of extension, you may need to secure various permits and approvals from your local council. These costs can vary, and failing to obtain the necessary permits can lead to fines and delays.
  5. Plumbing and Electrical Work
    If your extension requires additional plumbing or electrical work—such as adding new bathrooms or kitchens—you’ll need to factor these costs into your budget. Moving plumbing fixtures or installing new electrical wiring can significantly increase the cost of your extension.
  6. Site Conditions
    The condition of your property’s site also affects the cost. If your home is on a sloping block or has restricted access, this can add to the expense. Additionally, unexpected issues, such as poor soil conditions or the need to remove large trees, can increase costs.

Average Cost of a Home Extension in Melbourne

In Melbourne, the cost of a home extension typically ranges from $2,000 to $4,000 per square metre. A small extension (around 20 square metres) could cost between $40,000 and $80,000, while a larger extension (50 square metres or more) might range from $100,000 to $200,000. These prices can fluctuate based on the factors mentioned earlier, so it’s important to get a detailed quote from your builder before starting the project.

What Home Extensions Add the Most Value?

If you’re planning a home extension with the goal of increasing your property’s value, it’s worth considering which types of extensions are most likely to yield a high return on investment (ROI). Here are some of the top choices for value-adding extensions:

  1. Kitchen Extensions
    A spacious, modern kitchen is one of the most sought-after features in a home. Extending your kitchen to create an open-plan living space can make your home more functional and appealing to potential buyers. Kitchen renovations and extensions tend to offer a strong ROI, particularly if you focus on high-quality finishes and appliances.
  2. Bathroom Additions
    Adding an extra bathroom is another smart investment. Homes with multiple bathrooms are more attractive to families, and a well-designed bathroom with modern fixtures can significantly increase your home’s market value. According to the Office for National Statistics, adding a bathroom to your home can increase its value by up to 5%.
  3. Master Suite Additions
    Expanding your home to include a master bedroom with an ensuite can add luxury and comfort to your living space. Master suites are in high demand, particularly in family homes, and this type of extension is likely to boost your home’s resale value.
  4. Outdoor Living Spaces
    In Melbourne’s temperate climate, outdoor living areas are highly desirable. Extending your home to include a deck, patio, or covered alfresco area can enhance your lifestyle while increasing the value of your property.
  5. Granny Flats or Self-Contained Units
    Adding a granny flat or a self-contained unit to your property can provide additional living space for extended family members or create a rental income opportunity. This type of extension can significantly increase the value of your home, especially if it’s designed to be independent from the main house. Loft conversions can bring in around 20% of a value increase, the same as adding another room.
