Calculating Your Home Extension Cost: What You Need to Know

When considering a single-storey extension for your home, understanding the upfront cost is crucial. We at Inner West Home Extensions help you confidently plan by demystifying costs.

  • Materials: The quality and type of materials chosen impact the overall cost. Whether it’s the windows, doors, or walls, we use only high-quality materials that ensure durability and aesthetic appeal.
  • Labor: Our skilled team works efficiently to keep labor costs reasonable without compromising on quality. We manage our workforce to align with strict timelines and budget constraints.

Avoiding Additional Costs: 

Our Strategies for Keeping Your Budget Intact

We understand that managing the budget for your house extension is as crucial as the build itself. That's why we've developed effective strategies to ensure that when you choose us for your single storey extension, you invest in transparency and predictability.


Financial planning is key to avoiding common pitfalls that could inflate project costs. We start by helping you set a realistic budget for all aspects of your extension, from materials to labour costs. Our experience lets us provide you with an accurate estimate, broken down by square metres, so you know exactly where your money goes. Additionally, we discuss the importance of a contingency fund—typically 10-20% of the overall budget—to cover unexpected expenses without derailing your project.


Our proactive approach to managing unforeseen expenses involves meticulous upfront assessments of your property. This thorough evaluation helps identify potential challenges—be it with existing walls, plumbing, or the foundation—that could affect the cost down the line. We ensure all necessary building permits are obtained and that every aspect of the construction meets local regulations, reducing the risk of costly compliance issues.

Frequently Asked Questions About Single-Storey Extensions

  • 1. How much does a single-storey extension cost in the Inner West?

    The cost of a single-storey extension in the Inner West typically ranges between $2,500 and $4,000 per square metre, depending on the size, complexity, materials, and whether it involves wet areas like kitchens or bathrooms. For a standard 40m² rear extension, you can expect to invest $100,000–$160,000. Costs may be higher if you’re dealing with heritage homes, sloping blocks, or high-end finishes. We provide fixed-price quotes, so there are no hidden surprises.

  • 2. How long does it take to complete a single-storey extension?

    On average, a single-storey extension takes between 12 and 20 weeks from site start to completion. The timeline depends on the project’s complexity, approval timelines, weather, and supply availability. At Inner West Home Extensions, we provide a detailed schedule upfront—and we back it with our On-Time Completion Guarantee, meaning we work for free if we go over time.

  • 3. Do I need council approval for a single-storey extension?

    Yes, most single-storey extensions in Inner West require approval. This can be done through either:


    Development Application (DA) via your local council, or


    Complying Development Certificate (CDC) if your extension meets specific planning requirements (faster route).


    Our team handles the entire approval process, including site assessments, plans, and documentation, to ensure compliance with NSW planning laws and Inner West Council guidelines.

  • 4. Can I live in my home during the extension project?

    Yes, in most cases. Since single-storey extensions are typically done at the rear or side of the home, many clients stay in their home during construction. We implement safety barriers, manage dust and noise, and schedule major disruptions around your availability. If the project becomes too invasive (e.g., open-plan wall removal), we’ll advise the best time for a short relocation.

  • 5. Will the extension match my existing home?

    Absolutely. One of the key goals of a professional extension is to make the new space feel like it’s always been part of the original structure. We take special care with:

    • Matching bricks, roofing, and materials
    • Floor levels and ceiling heights
    • Heritage details (if applicable)

    Our design team ensures your extension blends seamlessly while still upgrading your home’s functionality and value.

  • 6. What are the most common uses for a single-storey extension?

    Popular uses include:

    • Expanding kitchens or dining areas into open-plan layouts
    • Adding extra bedrooms or bathrooms for growing families
    • Creating a home office, playroom, or media room
    • Extending living areas into alfresco zones for better indoor-outdoor flow

    Each design is tailored to your family’s needs, lifestyle, and property potential.

  • 7. How much value does a single-storey extension add to my home?

    A well-executed single-storey extension can add 15%–25% to your property’s value, depending on location, design, and build quality. In Inner West Sydney, where land is limited and lifestyle is a premium, added space and functionality significantly increase buyer appeal. According to CoreLogic, renovated homes in Inner West suburbs often sell faster and above suburb median prices compared to unrenovated ones.
