Warragamba: a dam-builders' town with post-war character
A purpose-built township
Warragamba is a surviving construction town for the dam, with a town hall, a central park and a small commercial area. According to the local library, the small homes, shopfronts and tight streets still tell the story of daily life during dam construction. The 2021 count put stand-alone houses at 97.4% of occupied homes. Attached homes were rare and no flats were recorded.
Conservation area controls
Wollondilly's development control plan (DCP) treats the original village as a conservation area. It wants new work to reflect the simple character of the town as built after World War II. That is different from copying a colonial cottage or a modern estate facade. The plan also values the town's tie to Sydney's water supply and its long outlook west to the Greater Blue Mountains. Mapping decides which land is covered, and the town's history alone does not turn each house into a listed item.
A compact centre
Council's centre study describes a small settlement with several activity points rather than one main street. Home projects and centre work therefore face different design questions. Pools and back extensions are governed by their lot's own controls rather than the centre's.
Typical work
Common projects and how they get approved
What owners build here
The detached houses here generate most of our work. Typical Class 1 and 10 jobs include:
- Internal reworking and modest rear additions to original workers' cottages.
- Replacement garages and carports, sized to narrow streets, tight access and modest frontages.
- Second storeys, tested carefully against the street pattern, neighbouring houses and the heritage controls.
- Pools and barriers, fitted around access and existing outdoor space.
- Granny flats, where the lot size, intended use and servicing allow.
We pass on work for new shops and business premises in the centre, since it sits beyond Class 1 and 10.
How approval usually works
Start with a measured survey and any past approvals, not assumptions from the town's history. On mapped conservation land, match the size, shape and finishes of the post-war village. A CDC, the quicker approval under state rules, may still work. Its limits and exceptions hinge on the code, the type of job and the precise heritage status. A conservation area is also handled differently from a listed item. The view controls towards the Blue Mountains apply to new commercial buildings, not to a backyard shed. Narrow streets also make driveway access and garage placement worth checking early. When a DA is required, settle the heritage questions ahead of the construction certificate. CertifiBuild confirms your lot's heritage position and access constraints early, so additions suit the village without surprises.

See the council pageCan I enlarge my original Warragamba workers’ cottage?
Often, yes, provided the design suits the heritage and character controls. Wollondilly’s development control plan (DCP) maps the original village as a conservation area, asking new work to reflect its simple post-war character, rather than copying a colonial cottage or a modern estate look. Start with a measured survey and any past approvals, because your actual house and lot dimensions shape what fits, not the town’s history. Modest rear additions are the usual approach. Check how the extension affects the street, access and neighbours before choosing between a complying development certificate (CDC) and a development application (DA).
Does the conservation area block every CDC in Warragamba?
No. Whether a complying development certificate (CDC) is available in Warragamba depends on which code applies, what the work is and your lot’s exact heritage status. A listed property is handled differently from one that is simply inside the conservation area. Some jobs, such as certain pools and detached outbuildings, may still qualify. Mapping decides which land is covered, not the town’s dam-building past. Test your actual proposal, whether a pool, alteration or shed, against the code and your planning certificate before assuming a development application (DA) is the only option.
Can I turn my carport into a closed garage?
Possibly. Closing in a carport alters its shape, its access and its look from the street, so set the original approval beside the full new proposal. Warragamba’s narrow streets and modest frontages make car space and the gaps to neighbouring houses worth measuring carefully. On mapped conservation land, the new garage must also fit the plain post-war character protected by the development control plan (DCP). A garage is Class 10 work, so once the heritage position is clear, you can confirm whether code approval or a development application (DA) applies.
