Single & Two Story Granny Flats

Two story granny flats are starting to become a lot more popular as investors and families are realizing the potential of placing one of these homes in their backyard!

The types of granny flats we build

  • Detached Granny Flats

    A detached granny flat is a standalone secondary dwelling on a block that already contains a main dwelling. Building a detached granny flat can be perfect to use as an investment, as it has a separate entryway to your main house and most often a fence between the two buildings to create more privacy for your family or tenants.

  • Attached Granny Flats

    An attached granny flat is joined to the main dwelling on the property and is designed to fit seamlessly with your home. By altering the orientation of the granny flat we can either maximise your privacy or increase the interaction between the occupants.

  • Granny Flat with Garage

    Did you know you can build a granny flat with a garage attached? Well, you can! The State Environment Planning Policy (SEPP) permits a granny flat to be built with an internal living space of 60m2.

  • Two Story Granny Flats

    Two-story granny flats are starting to become a lot more popular as investors and families are realizing the potential of placing one of these homes in their backyard! Two story granny flats come in different shapes and sizes, however, like single-story granny flats, they are restricted to 60m2 of internal habitable space.

Our experience with Steve was really positive. We appreciated his friendly smile and help backed by many years of experience which resulted in exactly what we wanted in a short period of time. The workers he used were all friendly, respectful and top-quality tradesmen. The result was a quality build that couldn't be faulted. I would recommend My Granny flats in Sydney for any granny flat project.

I cant speak highly enough of Steve and his team.
They were an absolute pleasure to work with. Always on time and stuck to the schedule making our building experience very stress free. Nothing was too much trouble and any adaptations were discussed professionally and promptly with Steve always available when needed.
Their workmanship is amazing and our finished building is exactly as I had planned.

My Granny Flats provided us with a high quality granny flat at a very reasonable price. Customisation of the fit out was easy to arrange and their after sales service has been excellent.
Very good value for money with excellent customer service.
I would definitely consider using Fox again if I need another granny flat.

Even though I am not yet a granny, I purchased the smallest of the granny flat homes which were built, on a little bit of land I had already bought. The whole process was made smooth by my being able to contact Steve directly with any questions and he and his team were wonderful. Many thanks to all of you at My Granny Flats!

Steve and the team from My Granny Flats Sydney were a total pleasure to deal with. Not only were they super accommodating and happy to adjust their standard designs to exactly suit our needs but also helped us find a builder and the right finance to get the project off the ground. We would happily recommend them to our family and friends and use them again ourselves.

The guys at My Granny Flats were super friendly and easy to deal with throughout the whole process. We had a bunch of changes to their standard model which was no issue what so ever. The whole process was very smooth – even the council approvals. Couldn’t be happier – our little Granny Flat is awesome! Highly recommend Steve and the Team at My Granny Flats in Sydney
