About Us

We take education, legislation, and compliance seriously and work hard to stay up to date with the latest information and/or changes by working with Councils, Private Certifiers and Engineers. This allows us to deliver correct information, assess with accuracy and provide honest up front pricing.

Our construction crew are known for their attention to detail and consideration for tenants, neighbors and owner occupiers during the building process. Special attention is given to site safety to keep all occupants and tradesmen safe for the duration of the project.

By the way, when you engage Granny Flats Australia with your project, you have assurance that we are the building company. Construction is not outsourced.
