Custom Built Granny Flats in Sydney

At Inhouse Granny Flats, we understand that every person is different. We know that a set design may not be to your liking. Unlike other companies, we allow every client the opportunity to specifically design their own layout. Every backyard is different, why should you settle on a layout that wasn’t designed for you? Liaising with our onsite granny flat designer, each customer will be able to create their own floor plan, including room sizes and change of location. That way your granny flat will be unique and one of a kind.

  • 1. Getting a Quote

    1. Getting a Quote

    The first step to building a granny flat is an enquiry. When you call or email us, we will send you a free information pack so you get a better understanding of what we do. From there, our qualified builder will inspect your backyard free of charge to check the area and discuss your needs and requirements. Our sales representative will then send you a fee proposal, which outlines the necessary requirements for your granny flat as well as its inclusions and overall price.

    Once we have received your survey our qualified Inhouse design team will then draw up a concept floor plan and organise a personalised meeting to sit down with you to ensure your needs are met and any design alterations are made.
    Once you are happy, we will proceed to start your approval with a private certifier or via council.
