Are You Buying a Granny Flat… or Just a Kit? What Adelaide Homeowners Need to Know!

Quality Australian Designed & Built
With the rising demand for granny flats, backyard studios, and garden rooms in Adelaide, more companies than ever are entering the market.
At first glance, this seems like a good thing - more choice, more competitive pricing.
But we’re hearing the same story more and more from customers:
They thought they were getting a fully installed building… but instead signed off on a kit!
And often, this isn’t realised until the very end - buried in the small print.
The Hidden Reality Behind “Affordable” Granny Flats
Across Australia (and globally), the housing crisis has driven a surge in prefabricated granny flats and garden rooms.
With so many options available, it can quickly become overwhelming.
Many of the lowest-priced options you see advertised are actually:
Builder’s kits
Delivered to your site
With major components not included
These kits are often dropped off on your driveway - leaving you to organise:
Installation
Trades
Compliance
Additional costs
What seems like a great deal upfront can become far more complex (and expensive) than expected.
⚠️ Beware of the Small Print
This is where many customers get caught out.
Key inclusions are sometimes excluded or unclear — especially when:
Comparing quotes
Reviewing contracts
Or signing off at the final stage
Before committing, it’s essential to understand exactly what you’re getting.
✅ Checklist: What to Confirm Before You Sign
If you’re exploring a granny flat or garden room in Adelaide, use this checklist to avoid surprises:
1. Is the Engineering Site-Specific?
If documents are included, confirm that:
Engineering is tailored to your block
Not generic or reused across multiple builds
2. Are Footings Included?
Footings are critical — and often excluded.
Check:
Are footings included in your quote?
Is footing engineering based on your soil report?
3. Is This a Kit or a Full Build?
This is one of the most important questions.
👉 Ask clearly:
Is this a kit only, or a fully installed building?
Many customers only realise too late that installation is not included.
4. Is Installation Included?
Confirm both:
Installation of footings
Installation of the building
If not included, you’ll need to coordinate multiple trades yourself.
5. Are Compliance Certificates Provided?
For a compliant, habitable structure, you’ll need certificates for:
Glazing
Bathrooms
Waterproofing
Electrical
Without these, you may face issues with approvals or future use.
Why This Matters More in South Australia
In Adelaide and across South Australia, approvals, site conditions, and compliance requirements can vary significantly.
Choosing the wrong type of build (or misunderstanding inclusions) can lead to:
Delays
Unexpected costs
Approval complications
The Difference: Kit vs Turnkey
At Inoutside, we often speak with clients who initially explored kit options — only to realise the complexity involved.
That’s why we focus on full turnkey solutions, where everything is managed for you:
Planning and approvals
Site preparation and footings
Full installation
Internal fit-out
No hidden surprises. No chasing trades. No confusion.
Final Thoughts
If you're considering a granny flat or garden room in Adelaide, take the time to look beyond the headline price.
The most important question isn’t:
❌ “How cheap is it?”✔️ “What’s actually included?”
Because in many cases, the difference between a kit and a complete solution is everything.
