We provide homeowners with the clarity, data and builder-neutral advice needed to build a granny flat with confidence. Your independent resource for Australian granny flat planning — regulations, costs, and design, without the builder bias.
Why We Built This Site
Building a granny flat in Australia is one of the biggest property decisions a homeowner can make. Yet finding genuinely unbiased information is surprisingly hard.
Most granny flat websites are run by builders, kit home companies, or lead generation businesses. Their content exists to sell you something.
Granny Flat Guide was created to do the opposite.
We are an independent, builder-neutral information hub. We do not sell construction services, take commissions from builders, or accept payment to recommend specific companies. Our only goal is to give Australian homeowners the honest, accurate data they need to plan their project with confidence.
