Granny Flat Builders in South West Sydney

A standalone granny flat is a separate, self-contained home built on a property that already has a house. It can give a family member independence close by, or extra space for your household.

Planning a granny flat

What makes a granny flat work

  1. Compact living that works

    In a smaller footprint every metre counts. Good planning keeps living, sleeping and storage clear of each other so the space does not feel cramped.

  2. Practical kitchen and bathroom

    A kitchen sized for real daily cooking and a bathroom that is easy to use, including for older family members if that matters to you.

  3. Privacy for both households

    Window placement, screening and where each outdoor area sits help the granny flat and the main home each keep their own space.

  4. Access

    How people reach the granny flat from the street, whether it has its own path or gate, and how deliveries and visitors find it.

  5. How it relates to your home

    Its position in the yard affects sunlight, views, the backyard you keep and how connected or separate the two homes feel.

Not every block suits a granny flat

Block size, shape, access and the rules that apply to your property all affect whether a granny flat is possible and where it could go.

Before you get in touch, it helps to know your address, roughly how much backyard you have, how you would reach the granny flat from the street and who it is for.

Common questions

Is a standalone granny flat the same as a house with granny flat?

No. This page is about adding a granny flat to an existing property. If you are building a new main home too, see house and granny flat builds.

Who are granny flats usually for?

Often a parent, an adult child or another family member who wants their own space nearby. Tell us who it is for and we can plan around their needs.

Can my block fit one?

It depends on your block and the rules that apply to it. Share your address and a few photos of the yard and we can talk it through.
