Single & Two Story Granny Flats

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.

We recently built a granny flat with My Granny Flats and are very satisfied with the quality and speed of the service. Designs and approval were hassle-free. Our site supervisor, Steven, was very understanding, easy to work with and was very quick to rectify any of our concerns.

We recently built a granny flat with My Granny Flats and had a fantastic experience! They offered quality inclusions in comparison to competitors and were quick to responses. Steve was taking lead throughout the build and kept us informed along the way. He always made time available to us to review the granny flat when it suited our schedule and was quick to address any areas of concern.

Steve, the director of the company is a very passionate person and happy with the staff. We're happy with the outcome of the granny flat they built for us. The inclusions were of high quality. We are happy to recommend them to other people who are intending to build one for either extra space, to downsize or for additional income.

Prompt in addressing queries and concerns, quality work without hassles. No great price variations from original quote/agreed amount which means no headache in my bank account! Approachable staff available at every stage of the build whenever I needed clarification. Would work with them again definitely.
