Interior Range
Three coordinated interior finish themes for Adelaide granny flats, each a complete material and fixture palette rather than a room-by-room decision — chosen independently of your floor plan and carried consistently through the whole build.
Three named themes, each a coordinated palette across cabinetry, benchtops, fixtures and flooring, viewable in person as part of a design consultation.
Coastal-suburb builds around Brighton and the surrounding beachside strip often lean toward lighter, north-facing interior palettes, while Adelaide Hills builds tend toward warmer, timber-heavy finishes — the theme choice usually follows the block's light and setting, not just personal taste.

Interior Range
The Themes
Sandstone
Warm neutral tones, timber-look cabinetry and honed stone benchtops — a soft, considered palette suited to most design ranges.
Ironbark
Dark cabinetry, matte black fixtures and a charcoal-toned material palette for a bolder, more contemporary finish.
Limestone
Light, coastal-toned finishes with pale cabinetry and a bright, airy material palette — suited to north-facing designs like The Aldinga.
Which Theme Suits Your Build? — Where to Go Next
| Your preference | Suggested theme | Where to go |
|---|---|---|
| Warm, timeless, easy to match to most homes | Sandstone | Design consultation |
| Bold, contemporary, dramatic contrast | Ironbark | Design consultation |
| Bright, coastal, maximises natural light | Limestone | Design consultation |
| Choosing your floor plan first | Any theme pairs with any layout | Design Range |
| A block or brief no named layout suits | Themes still apply to a custom design | Custom Granny Flat Builders |
The floor plan and the interior finish are two separate decisions — choosing a theme doesn't lock you into a specific design range.
How to Choose a Theme
Each theme is a complete, coordinated palette across cabinetry, benchtops, fixtures and flooring, designed to be chosen once and carried consistently through the whole build rather than picked room by room. Any theme pairs with any layout from the Design Range or a fully custom design — the two decisions are independent of each other.
Unlike a named design range, an interior theme isn't priced as a standalone product — it's a finish-level uplift applied to whichever floor plan you choose, so the cost impact shows up in the overall build budget rather than as its own line item. See our cost guide for how finish level affects the total.
Choosing a Theme: Three Things to Consider
If your block faces north or gets strong natural light, Limestone's pale, light-reflective palette tends to suit the space better than a dark theme, which can read as heavy in a bright room.
If you want the interior to feel cohesive with an existing period or heritage-style main house, Sandstone's warmer, timber-heavy palette generally bridges the two better than a stark contemporary theme.
If you're undecided, see the finishes in person at a design consultation before committing — photos and swatches read differently to standing in a room with the actual materials.
FAQs
Common Questions About the Interior Range
Can I mix elements from different themes?
Each theme is designed as a coordinated palette, but specific changes can be discussed at the design consultation stage.
Does the interior theme affect the overall cost?
Finish level is one of the biggest factors in overall cost, though a theme isn't priced as a separate line item — see our cost guide for how this plays out across the different bands.
Can I see these finishes in person before deciding?
Yes — this is covered as part of the design consultation.
Does my choice of interior theme limit which design range I can use?
No — any theme pairs with any design range layout, or with a fully custom design.
Which theme suits a coastal-suburb block?
Limestone's lighter, coastal-toned palette generally suits north-facing coastal blocks best, though this comes down to personal preference as much as the block itself.
