How Much Does a Home Extension Cost in Melbourne?
The cost of a home extension in Melbourne depends largely on the size, design, and materials used. For a basic single-storey extension, you can expect to pay between $1,350 to $2,100 per square meter, while more complex projects, such as second-storey additions, often range from $3,150 to $4,000 per square meter. For example, an 80m² ground-floor extension typically costs between $164,500 to $310,000, while a second-storey extension could add 50% more to the total price.
Types of Home Extensions and Their Costs
- Single-Storey Extensions: Typically, the most affordable type, costing between $1,350 to $2,100 per m². If you’re adding an 80m² extension, the cost can range from $164,500 to $310,000 depending on the materials and design.
- Second-Storey Extensions: This is a popular choice for homeowners looking to maximize space without losing outdoor areas. However, it is more expensive due to structural reinforcement, and costs range from $320,000 to $640,000.
- Garage Extensions: Converting or extending your garage is generally more affordable, with prices typically up to $20,000, depending on whether additional structural or utility work is required.
Factors Affecting the Cost
- Materials: The type and quality of materials have a significant impact on the cost. For example, timber-framed extensions are often cheaper than brick veneer, but the latter may offer more durability and insulation benefits.
- Design Complexity: A simple room extension will cost less than adding a kitchen or bathroom, which requires additional plumbing, electrical work, and higher-end materials. A bathroom or kitchen extension can add between $10,000 to $35,000 to your overall budget.
- Permits and Planning: Before construction begins, you’ll need to secure the appropriate permits from your local council. This can cost anywhere from $500 to $2,000, depending on the scale of your extension.
- Hidden Costs: Excavation, insulation, and installation of HVAC systems can increase your final budget by 10-20%. For example, installing air conditioning, plumbing for a bathroom, or even additional electricity wiring may lead to higher unforeseen costs.
The Value of a Home Extension
Beyond adding more space, a well-executed home extension can significantly boost the value of your property. Melbourne’s growing property market makes home extensions a worthwhile investment for many homeowners. However, it’s essential to plan your budget carefully to avoid cost overruns, which can erode the return on your investment.
For example, extensions that focus on high-utility areas like kitchens or additional bedrooms tend to add the most value to your home. On the other hand, basement or cellar conversions can be expensive, ranging between $250,000 to $500,000, and may not always offer a high return unless executed with the future sale in mind.
Insights and Counter-Arguments
While home extensions are often seen as a more affordable alternative to moving, they do come with their own set of challenges. For instance, living through construction can be disruptive. Some homeowners choose to move out temporarily, which can add to overall costs.
Others may consider the environmental impact of large-scale renovations, opting for eco-friendly materials and energy-efficient designs to reduce long-term costs.
Additionally, while DIY extensions may seem appealing for the budget-conscious, they can result in costly mistakes. Engaging a professional builder ensures that the job is done to code and reduces the risk of future structural problems.
