What a granny flat costs in the Lockyer Valley.
Prices, the local rules, and which models fit your block. Delivered from Laceys Creek, about 90km away, with full install on the table.
The rules in the Lockyer Valley.
| What matters | Where it stands |
|---|---|
| Maximum size | Set by the Lockyer Valley planning scheme and your zone. Rural residential blocks carry generous caps. We confirm the number for your lot before you sign. |
| Approval pathway | Most compliant secondary dwellings go through building approval with a private certifier, not a council DA. We confirm the pathway for your lot before you commit. |
| Who can live in it | Rent it to anyone. The old family-only rule was removed in September 2022. |
| Setbacks and siting | Zone-driven. Confirmed for your lot in the site review. |
| Car parking | Confirmed per site. |
| Services | Rural blocks here often run tank water and septic rather than town services. We price the connections before you sign. |
| Overlays | Flood on the valley floor, mapped hard after 2011 and 2022, and bushfire on the ridgelines. Both are checked in the site review. |
Which models fit here.
Ticks assume a rural residential zone, the most common Lockyer enquiry. Township zones can cap tighter. We confirm every rule for your site before you sign anything. Current as at September 2026.
What the council part costs.
Costed from our completed builds at Wavell Heights and Petrie.
Certifier, survey, soil, bushfire, energy report, engineering. Invoiced range across our completed jobs. Typical. Hard crane access has run to $51,000; we quote after seeing your block. 3.4m wide models travel as standard loads; 4.0m models need a pilot vehicle.
Four ways to buy.
The Standard 8.4, our one bedroom module. Prices include GST. The all-in column is the finished, liveable number with approvals and site works included.
| Option | You pay us | All in, liveable |
|---|---|---|
| Kit | $59,900 | $158,800–$207,600 |
| Lock-up | $75,900 | $174,800–$212,700 |
| Complete | $139,900 | $176,900–$189,900 |
3 towns in the valley.
The valley’s centre, with big flat blocks and the uni campus. Flood mapping decides footing height on the low side of town.
Older town blocks and acreage on the edges. The 2011 and 2022 flood lines are mapped, and we check them before anything else.
Growing fast off the Warrego Highway. Easy truck access makes it the simplest delivery run in the valley.
