Design Range
Four named design collections for Adelaide granny flats, each a considered starting point rather than a generic catalogue plan — choose one as-is, adapt it slightly, or pair it with any theme from our Interior Range.
Four named designs, each adaptable to minor site changes, with full council approval and project management included.
Blocks across the Adelaide Hills foothills, Blackwood among them, often suit a design range's proven layout better than a fully custom build, since the block shape is closer to standard than a steep escarpment site.

Design Range
The Collections
The Stirling
A family-scale two-bedroom layout with a generous open living space and covered outdoor area, suited to a standard-width block.
The Hahndorf
A compact one-bedroom design with vaulted ceilings and full-height glazing to the living area, suited to a narrower block or side-yard site.
The Aldinga
A two-bedroom layout designed around a north-facing living wing for natural light and cross-ventilation.
The Victor Harbor
The largest layout in the range, built around two bathrooms for independent multigenerational living or a premium rental.
Which Range Suits Your Block? — Where to Go Next
| Your situation | Suggested starting point | Where to go |
|---|---|---|
| Standard-width block, family-scale brief | The Stirling | Design consultation |
| Narrow block or side-yard site | The Hahndorf | Design consultation |
| North-facing rear yard, want maximum natural light | The Aldinga | Design consultation |
| Independent living or premium rental, want two bathrooms | The Victor Harbor | Design consultation |
| Sloping, irregular or heritage-overlay block | None of the four fit — go custom | Custom Granny Flat Builders |
| Deciding fixtures and material palette | Any range pairs with any theme | Interior Range |
The floor plan and the interior finish are two separate decisions — a named range doesn't limit which interior theme you can pair it with.
How to Use the Design Range
Each named range is a considered starting point, not a rough concept to be redrawn from scratch. Choose one as-is, or use it as the base for minor changes to suit your block's exact dimensions. Every range pairs with any theme from the Interior Range, so the floor plan and the finish level are decided independently of each other.
If your block is sloping, irregularly shaped, or carries a heritage overlay, none of the four ranges may be the right starting point — see Custom Granny Flat Builders for a design built around your site's specific constraints instead. A design range works best on a reasonably standard block; a genuinely difficult site is where custom design earns its extra cost.
Choosing a Range Instead of Custom: Three Things to Know
If your block is close to a standard rectangular shape, starting from a named range saves real design and documentation time compared to a fully custom design — you're not paying for site-specific engineering work your block doesn't need.
If you're not sure which range fits your brief, prioritise bedroom and bathroom count over layout details first — The Stirling and The Aldinga both suit a two-bedroom family brief, while The Victor Harbor's two bathrooms matter most for independent living or rental use.
If a range is close but not quite right, ask about minor adjustments before assuming you need a fully custom design — small changes to a proven layout are usually far cheaper than starting from a blank page.
FAQs
Common Questions About the Design Range
Can I modify a design range layout?
Yes — each range is a starting point. Minor layout changes are common; for substantial changes on a block that doesn't suit any of the four ranges, a fully custom design is usually the better path.
Does choosing a design range limit my interior finish options?
No — any range can be paired with any theme from the Interior Range, so the floor plan and finish level are separate decisions.
How much does a design range build cost compared to custom?
A design range build generally has lower design and documentation costs than a fully custom design, since nothing needs to be drawn from scratch — see our cost guide for real numbers.
Which range suits a rental property?
The Victor Harbor, with two bathrooms, is generally the strongest rental option for independent living, though The Stirling also suits a family-scale rental brief.
What if my block doesn't suit any of the four ranges?
See Custom Granny Flat Builders — a design built around your specific site constraints, common for sloping, irregular or heritage-overlay blocks.
