Building a Granny Flat? We’ve Done the Research So You Don’t Have To.
The Granny Flat Guide is Australia’s independent resource for secondary dwellings. We exist to solve one problem: the construction industry is confusing. From vague council rules to hidden builder costs, it is hard to get a straight answer. We fix that.
A Clear Path in a Crowded Market
The journey to building a granny flat can be overwhelming. Conflicting information, complex council regulations and a huge choice of builders make it hard to know where to start. We believe it should not be that difficult. We built this guide to be your trusted partner, with a clear, step-by-step path from first idea to final handover.
- Compare prefab, kit and custom build paths with real cost bands.
- Check CDC versus DA likelihood before you pay for drawings.
- Use vetted supplier directories and independent reviews, not sales brochures.
Our Commitment to You
100% Independence
We're not a builder or a manufacturer. Reviews and guides come from impartial research, with one aim: helping you make a clearer choice.
Primary-source research
The Granny Flat Guide Team tracks Australian manufacturers, planning portals and owner-builder paperwork. No generic filler, and no trade-licence claims we cannot back with a public source.
Total Transparency
From real build-cost bands to pro-versus-con reviews, we try to show the full picture: including the fees builders leave out of the brochure.
Independent Research for Australian Homeowners
The Granny Flat Guide is an independent Australian research hub. Guides, cost bands and supplier reviews are published by The Granny Flat Guide Team, this site’s editorial organisation. It is not a named tradesperson and not a personal blog. We are not a builder, certifier or financial adviser.
Granny flat research online is noisy: builder marketing, vague council summaries and headline kit prices that exclude slab, trades and approvals. This site focuses on costs, rules and build paths you can verify with your council and licensed trades.
How We Create Our Content
Data-Driven Research
Price guides are built from real quotes sourced from Australian suppliers and cross-referenced against current raw material indices.
Regulatory Compliance
Permit advice is checked against state legislation, including the Victorian Building Act 1993 and the NSW SEPP (Housing) 2021. We link directly to government sources.
Human Verification
Every article is edited and checked against primary sources before publication. We use drafting tools for speed, but nothing goes live without a human review pass. See our editorial standards.
