House Extension Costs in Melbourne

The desire for more space is common for Melbourne homeowners. As families grow and needs evolve, a fresh start isn’t always the answer. Extending your existing home offers a compelling solution, adding valuable square footage without the upheaval of moving. But the question that lingers on everyone’s mind is: how much does a house extension cost in Melbourne?

While there’s no one-size-fits-all answer, this comprehensive guide from Extensions Unlimited, Melbourne’s trusted home extension builders, aims to shed light on the factors influencing house extension costs and give you the knowledge to make an informed decision.

Understanding Price Variations: Second Storey vs. First Floor

The cost of your house extension will primarily depend on the type of extension you choose. Here’s a breakdown of the general cost ranges for Melbourne extensions.

First Floor Extensions​

Ground floor extensions provide the opportunity to expand your living space outwards, potentially creating a more seamless connection to your backyard. This type of extension can be ideal for adding a larger kitchen and living area, an additional bedroom, or even a home office. However, ground floor extensions can have more variable costs compared to second storey additions.

Site access plays a significant role. Limited access to machinery and materials can necessitate creative solutions, potentially impacting the budget. Demolition of existing structures or significant excavation work required for foundations can also add to the cost. Additionally, the overall scope of internal renovations needed should be factored in. For instance, will the extension require structural changes, or plumbing and electrical upgrades to integrate seamlessly with the existing house? These factors contribute to the variability in first floor extension costs. Consulting with our reputable local builders for a customised quote is crucial to get a more accurate picture of the potential prices involved in your specific project.

Second Floor Extensions

Second storey additions offer an attractive solution for maximising space without sacrificing valuable backyard area. They’re generally quicker and more cost-effective per square meter compared to first floor extensions due to less foundation work required. However, there are still factors that can influence the final cost.

The complexity of the roof structure plays a role. A simple gable roof will be less expensive than a multi-faceted or skillion design. Additionally, if your existing house requires significant structural reinforcement to support the additional storey, this can add to the final cost. That being said, second storey extensions typically offer a predictable cost range, falling within the $260,000 to $350,000 range for most projects in Melbourne.

Key Factors Influencing House Extension Costs

Now, let’s delve deeper into the key factors that can significantly impact the final price of your house extension project:

Size and Complexity of the Extension: As expected, the larger and more complex your desired extension is, the higher the cost will be. This includes the square meterage of the addition, the number of storeys added, and the presence of intricate architectural features.

Site Access and Engineering Requirements: The ease of access for machinery and materials to your property can influence the cost. Sloped sites, limited access points, or the presence of mature trees that need removal can all add complexity and potentially increase costs. Similarly, engineering requirements for foundations, support beams, or specific materials can also impact the final price.

Materials and Finishes: The type of materials you choose for your extension will play a significant role in the overall cost. High-end finishes, customised joinery, or specific building materials can elevate the aesthetics and functionality of your extension but will also come at a premium price.

Demolition and Excavation (Ground Floor Extensions): For ground floor extensions, any demolition of existing structures or significant excavation work needed will add to the overall cost.

Permits and Approvals: Obtaining the necessary permits and approvals from your local council is an essential step in the extension process. While we take care of this for you, these permits typically incur fees that will be factored into the quote.

Builder Expertise and Experience: A reputable and experienced extension builder like Extensions Unlimited can offer valuable cost-saving insights and ensure efficient project management, ultimately contributing to a more cost-effective outcome.

The Value of a Well-Planned Extension

While cost is undeniably a crucial factor, it’s important to consider the long-term value a well-planned house extension can bring to your property. Here are some key benefits to consider:

Increased Living Space: House extensions offer a practical solution to address space constraints. Whether you need extra bedrooms, a dedicated home office, a larger living area, a new kitchen, or simply a more functional layout, an extension can significantly enhance your living comfort.

Boosted Property Value: A well-designed and executed house extension can add significant value to your property. The additional square footage, improved functionality, and modern updates can make your home more attractive to potential buyers in the future.

Enhanced Lifestyle: A well-planned extension can transform your living experience. Imagine a dedicated space for hobbies, a luxurious ensuite bathroom, or a seamless indoor-outdoor connection to your backyard – these improvements can significantly enhance your day-to-day life.
