Cullen Bullen: a mining village on the Mudgee Road
North of Lithgow
Cullen Bullen is a village on the Mudgee Road about 28 kilometres north of Lithgow, at a height of around 880 metres. It was first surveyed in the 1820s, had a post office by the 1860s, and is supported by local mines and the Mount Piper power station. It is small, so each block is likely to be a standalone house or farm lot.
Land with a mining past
Because the area has a mining history, check mine subsidence mapping and any land contamination before you design. Parts of the Lithgow area are inside declared subsidence districts, which adds an approval beyond the usual certificate or consent.
Zone and lot size
The Lithgow Development Control Plan 2021 (DCP, council’s detailed design rules) splits housing and shed limits by zone and lot size, so measure your block and confirm its zone first.
Typical work
Common projects and how they get approved
What owners build here
Cullen Bullen’s village and rural blocks lead to practical projects. Typical jobs we certify include:
- New houses on village and rural lots.
- Sheds, workshops and garages within the limits for the zone.
- Extensions and verandahs on existing homes.
- Granny flats, where zone, servicing and the size limit allow.
- Carports and driveways, with width and grade checked.
How approval usually works
Check mine subsidence and bush fire maps before you commit to a design, since either can change the structure, siting or cost. If the lot is in a declared subsidence district, approval from Subsidence Advisory NSW is needed on top of the usual one. Confirm zone and lot area, because they decide which part of the DCP governs a shed or house. A complying development certificate (CDC, the fast-track route under state rules) can suit some jobs if the design and block both comply and no mapped hazard rules it out. Larger sheds and hazard-affected lots often need a development application. CertifiBuild checks which rules apply before anything is ordered.

Local questions
Questions we hear about this suburb.
No two lots in Cullen Bullen are the same. Give us your address and we will check every map that affects it.
See the council pageIs my Cullen Bullen block affected by mine subsidence?
Possibly, because the area has a mining history and parts of the Lithgow area are inside declared subsidence districts. Check your lot against the state mapping. If it is inside, building needs Subsidence Advisory NSW approval in addition to the usual certificate or consent.
What size shed can I build on a rural lot in Cullen Bullen?
On rural land and larger R5 lots, the Lithgow DCP 2021 allows a bigger total outbuilding area than on small urban lots, with limits on the size of any single building and its height, and larger boundary setbacks. Confirm your zone and lot area first.
Do I need a bush fire assessment?
If your lot is on the council’s bush fire prone land map, yes. The building must meet its assessed construction level, and an asset protection zone can take up part of the site. Check the map for your parcel and not just the village.
