How much does a home renovation or extension cost in Perth?

The cost of a renovation or extension depends on several factors, including the size of the project, complexity, material choices, structural requirements, and level of finish. Unlike new builds, renovations don’t have a simple square-metre rate because the existing site conditions and access have a big impact on price. The cost is also influenced by the standard of specification that comprises the project – such as kitchens, bathrooms, or structural modifications. At Addstyle, we offer a fully bespoke service to assess your home and provide a realistic cost estimate based on your specific requirements.

How long does a renovation or extension take?

The timeline depends on the scope of work. A small renovation may take a few months, while larger extensions or second-storey additions typically take 6–12 months. You must also allow time for the design process and council approvals. We provide a guide to timeframes at the start of the project to help you plan accordingly.

Do I need council approval for my home renovation or extension?

Most structural changes require council approval, especially if they involve extending the home’s footprint, changing the exterior, or adding a second storey. Some minor renovations may not require development approval, however all building work over $20,000 requires a building permit. At Addstyle, we handle the entire planning and approvals process, ensuring compliance with local building codes and minimising any delays.

Can I live in my home during the renovation?

In most cases you can comfortably live in the home throughout the duration of works, and most of our clients do choose that option.

Partitioning can be used to isolate the area of works from the home, or in the case of second storey additions, the works can be undertaken without breaking through to the ground floor until the late stages of the build.

    What are the considerations when deciding between a second-storey addition and a ground-floor extension?

    • Second-storey additions are ideal if you want to increase living space without sacrificing yard area. They also allow you to capitalize on potential views and improve the street presence of the home.
    • Ground-floor extensions work well if there’s available land and are great for open-plan kitchen/living/dining expansions, additional bedrooms, or alfresco areas.
    • The best choice depends on your block size as well as your lifestyle needs. We guide clients in making the right decision to maximise both functionality and property value.

    Can I stage my renovation to spread costs over time?

    Yes, some clients choose to stage their renovation for budgetary reasons. However, completing the work in one stage is usually more cost-effective due to mobilisation costs, permit fees, and economies of scale. If staging is necessary, we recommend prioritising structural work and leaving non-essential rooms or cosmetic finishes for later. We can help you develop a strategy that aligns with your timeline and financial goals.

    What factors impact the cost of a renovation?

    Several elements influence renovation costs, including:

    • Size and scope – Larger projects require more materials, labour, and time.
    • Material selections – High-end finishes and custom fixtures increase costs.
    • Structural modifications – Moving load-bearing walls or plumbing can add complexity.
    • Council approvals and permits – Some areas have stricter design requirements.
    • Site conditions – Access restrictions, sloping blocks, or older homes with outdated wiring or asbestos may require additional work.
    • Labour and trade costs – Skilled tradespeople are essential for quality results, and their expertise reflects in pricing.

    At Addstyle, we provide transparent and detailed project specifications to ensure the scope of work and material is clearly outlined. This helps avoid unwelcome surprises down the track.

    What are the benefits of renovating instead of moving?

    Renovating allows you to improve your home while staying in a location you love. Some key benefits include:

    • Customisation – Tailor your home to your exact needs and style.
    • Increased property value – High-quality renovations can significantly boost resale value.
    • Avoiding moving costs – No real estate fees, stamp duty, or relocation expenses.
    • Preserving character – Ideal for heritage homes or properties with sentimental value.
    • You can stay in the neighbourhood you love – No need to change the kid’s school or risk problematic neighbours.
    • You can save hundreds of thousands of dollars – By utilising the existing bones of the home you can achieve a ‘new’ home for reduced cost compared to a full new build.

    Rather than going through the stress of selling and buying a new home, a renovation or extension can create the perfect space without uprooting your family.
