    What Is a Granny Flat?

    A granny flat is an attached or detached small home on your property that can be used as a separate living space for a relative, friend, or tenant. Granny flats offer all the benefits of downsizing while still keeping your independence.

    Often a stand alone, self-contained home that can be used as an addition to your main property or as a stand-alone dwelling, granny flats are perfect for accommodating aging parents or dependants whilst having their own space to live. They’re also ideal for use as guest houses, home offices, or studios.

    • Is it moveable?
    • It is built out of non-permanent materials(no concrete/ foundations) and can be easily removed once the dependent person stops living there.
    • It will be occupied by a dependent person – someone who is incapacitated by medical, economic or social disadvantage, and depends on the person in the main dwelling.
    • There is no more than one person living in the unit.

    How much does it cost to build a granny flat in Mornington Peninsula?

    Assuming you’re looking to build a basic granny flat in the Mornington Peninsula, it would likely cost between $90,000 and $150,000. This price range covers construction costs for a typical one or two-bedroom unit with a kitchen and bathroom.

    Of course, the actual cost will depend on the specific features and finishes you choose for your granny flat. If you want to include high-end materials or custom designs, the cost will be higher. Similarly, if you’re building on a difficult or steeply sloping block of land, that will also add to the overall cost.

    To give you a better idea, let’s break it down into three different categories – small, medium, and large.

    For a small granny flat, you’re looking at spending around $60,000. This includes basic features such as one bedroom, one bathroom, a kitchenette, and a living area.


    If you want something a little bigger, then you’re looking at closer to $100,000 for a medium sized granny flat. This usually includes two bedrooms, one bathroom, a full kitchen, and a living area.

    And finally, if you’re dreaming of a more luxurious granny flat with extra features and fittings, you could expect to pay between $120,000 and $150,000.

    It’s important to remember that these costs are just an estimate – they will vary depending on your specific location and the materials and labor costs in your area. If you’re thinking about building a granny flat, it’s best to get in touch with a local builder for an accurate quote.

    Do I need council approval to build a granny flat in Victoria, Australia?

    To build a granny flat in Victoria, you must first obtain planning permit approval from your local council. The application process for this can be found on your council’s website. Once you have obtained planning permit approval, you will need to notify your local water authority and complete the relevant documentation to connect to services. You will also need to apply for a building permit from your local building authority and engagement of registered builders is essential.

    However, some companies take the hassle out of building a granny flat. They do all the paperwork for you and make sure everything is done according to regulations.

    How long does it take to build a granny flat?

    It really depends on the specific requirements and specifications of the granny flat, but generally speaking, it will take anywhere from 4 to 8 weeks to construct.

    It’s important to keep in mind that a granny flat is not just a small home – it needs to meet all the same building and safety regulations as a regular house. So, while the construction time may be shorter than for a traditional house, there is still some amount of work that goes into ensuring that everything is up to code.

    Does a granny flat add value to our property?

    A granny flat will adds value to your property.
