    We offer versatility and any internal design.
    We also offer proven designs with 2 and 3 bedroom layouts.


    At Superior Granny Flats our team are dedicated to providing just that; a superior range of modern granny flats. With a factory and showroom in Bayswater, Victoria, and offices in Underwood, Queensland, we are able to provide our services along the entire east coast.

    We work extensively on the Gold Coast, and in Brisbane, as Australians continue to flock to these growing centres that balance opportunity and lifestyle. If you would like to find out more about how you could build a granny flat in another part of Australia, then please get in touch with our team to discuss the options for having a prefab granny flat from Melbourne delivered to you.

    With certification in three states (Queensland Building and Construction Commission, Victorian Building Authority, New South Wales Government Fair Trading) we have become the trusted granny flat builders more Australians turn to.

    We build granny flats in Melbourne and maintain strong interstate relationships to ensure that our interstate services are not just an add-on, but an integral part of our business. This has led to Superior Granny Flats becoming the market leader in Northern New South Wales and Queensland when it comes to granny flat homes as primary dwellings, small granny flats for use as investment units, or granny flat plans that can be adapted to provide ideal secondary dwellings for larger families.

    Superior Granny Flats offer relocatable granny flats, temporary housing options, and unmatched advice. Our experts can assist in customising our one, two, or three bedroom granny flat floor plans in our Melbourne factory to your specifications.

    To find out more about the options available to you, feel free to contact the Superior Granny Flats team, and learn why we are known for providing kit homes that take their place amongst the best granny flats in Australia.


    Since 1990, Superior Granny Flats have been Australia’s choice for reliable granny flat builders. Melbourne based, with the capacity to send teams interstate for consultation and construction, you will find outstanding value for money when you choose us for your granny flat construction.

    Rather than setting out to build cheap granny flats, we strive to deliver outstanding value. The continuing popularity of our granny flat kits in Melbourne and beyond gives us the superior purchasing power and efficient turnover that allows us to offer our high quality granny flats at prices that you can afford.

    There’s no room for error, as we build over 150 units each year. We design and make our relocatable granny flats in Melbourne before arranging for the flat pack homes to be delivered to their destination and assembled on site.

    Access is never a problem, because we design and manufacture our granny flats in Melbourne before delivering them as flat pack prefab constructions to their destinations. Most granny flats are designed to offer accommodation within the backyard of an existing dwelling, making it very difficult when granny flat builders try to bring a fully constructed granny flat into a backyard where there is limited side access. Flat pack construction combined with the skill of an experienced team mean that you can have a relocatable, custom granny flat in your backyard sooner.

    We are the dedicated granny flats builders Australians turn to more often, because we can provide everything from a small backyard retreat, to sturdy, temporary housing units, and you know that the Superior Granny Flats team will always work to find the right unit for your needs and the available space. Our range of relocatable homes give you flexibility and choice, so that we can supply the solutions our customers need.


    Looking into building a granny flat for your home but not sure how to go about the process? Superior Granny Flats specialise in building granny flats, and will work with you through the entire process, from concept to actualisation. Our custom granny flats are created to suit your needs, and are designed to appease your concerns about the cost of building a granny flat.

    Because relocatable homes and backyard bungalows can be thought of as temporary structures, many people start their search looking for cheap granny flats. Our Melbourne team take a different approach. We manufacture using a range of granny flat designs so Melbourne homeowners and interstate customers alike can find a quality unit that suits their budget.

    If you still have concerns over a granny flat’s cost, then why not talk to our team today? We can offer you transparent pricing options, so that your never need worry about hidden fees or unexpected budget blowouts.


    With over three decades of experience, and with our granny flats for sale in Melbourne, Brisbane, and available to the rest of Australia as well, you know that every granny flat design in the range has been well tested for practicality and comfort.

    In addition to the variations available for these standard designs, we also offer you the option to design your own custom granny flat. Our team will draw up a concept plan for your approval, incorporating all of your ideas for shape, space, and layout.

    You may choose the custom option because you want a designer granny flat that perfectly complements and adds value to your home. Or you may choose customisation due to accessibility requirements that are not considered in the run-of-the-mill granny flats for sale in Victoria.
