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 are not a builder or a manufacturer. Our recommendations, reviews and guides come from impartial research, with one aim: helping you make the best choice.
Real-World Expertise
Our content is curated by researchers with direct access to Australian manufacturers and legislative databases. No generic advice, just practical insights.
Total Transparency
From breaking down real build costs to our pro versus con reviews, our goal is to give you the full picture, honestly and directly.
Independent Research, Grounded in Real Trade Work
The Granny Flat Guide is published by OakCodeAndTechSolutions, an Australian sole trader. Our editorial work draws on hands-on experience in residential electrical work, modular and portable housing websites, and owner-builder documentation in Australia. We are not a builder, certifier or financial adviser.
We built this site because granny flat research online is noisy: builder marketing, vague council summaries and headline kit prices that exclude slab, trades and approvals. We focus on costs, rules and build paths homeowners can verify with their 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.
Pick Up Your Research
Cross-check numbers, compatibility and local rules with official sources before you commit. Fee schedules, firmware requirements and council overlays change by state and postcode, so treat any single figure as a starting point. Use our tools and directories to compare options, then confirm with a licensed tradesperson, certifier or supplier before you sign.
