Private building certifier in Silverdale
Silverdale mixes established homes, rural land and the new estate where the Lion Safari Park once operated. CertifiBuild certifies sheds, pools, alfrescos and new homes here, and lot drainage is often what we look at first.

Local rules
Silverdale: ridge-top homes and the old Safari Park
A detached suburb on high ground
Council's centre report describes Silverdale as elevated land with views towards Sydney. Its small convenience centre grew out of a service station and the businesses around it. For the locality overall, 99.3% of occupied homes in the 2021 count were houses standing alone. Only the Wollondilly portion of Silverdale is covered here.
From safari park to housing estate
Wollondilly's development control plan (DCP) has a dedicated section for Marsh Road, the old Lion Safari Park. It covers release staging, street and path connections, landscaping and water quality. Stormwater must be treated as one integrated system, so water leaving the estate is no worse, or is better, than before. Those rules apply to the mapped release land only, not to older or rural lots elsewhere in Silverdale.
Not the same as Warragamba
Silverdale shares postcode 2752 with Warragamba, but not its history. Warragamba was purpose-built for dam workers and has its own heritage character controls. Those do not carry over here. Use the heritage mapping, zoning and lot category that apply to your Silverdale property.
Typical work
Common projects and how they get approved
What owners build here
Homes are almost all detached, so most work centres on houses. Typical Class 1 and 10 work includes:
- New houses on release lots, fitted to each lot's subdivision and drainage conditions.
- Pools and barriers, positioned around easements and approved drainage paths.
- Roofed alfrescos, with downpipes and paving included in the stormwater plan.
- Sheds and garages on larger established and rural-edge lots, clear of drainage lines.
- Extensions and rebuilds on older lots, working with the existing house position.
Granny flats hinge on zoning, lot size and what water and sewer services can reach the lot, so we look at those first.
How approval usually works
First, confirm whether your lot sits within the former Safari Park release area and get its subdivision consent. Check any new house there against those documents and council's residential controls. For backyard work, look up the drainage approved for your lot and any easements before placing a pool, an alfresco or a big paved area, because extra hard surfaces change runoff. Do not borrow Warragamba's heritage rules just because of the shared postcode. A CDC, which follows State code rules and moves faster, may fit if your land and design pass the criteria. Otherwise lodge a DA and resolve release-area and servicing conditions before the construction certificate. CertifiBuild checks drainage, easements and precinct coverage up front, so new structures fit the estate's approved system.

Local questions
Questions we hear about this suburb.
No two lots in Silverdale are the same. Give us your address and we will check every map that affects it.
See the council pageWhere do I start with a new house on former Safari Park land?
Start with the section of Wollondilly’s development control plan (DCP) for Marsh Road, the release area on the old Lion Safari Park site, and the subdivision approval for your lot. These cover staging, street and path links, landscaping and how stormwater is managed across the estate. Then look at the general house rules and any drainage or siting conditions on your title. Once those are clear, test the house design against the complying development certificate (CDC) code. Where it falls short, a development application (DA) to council is the route, with a construction certificate after it.
Once my Silverdale home is finished, can a pool go in?
Often, yes. Your lot, the pool design and the approval route all need to line up. On the former Safari Park land, check the easements, the drainage approved for your lot and how much yard is left before choosing a spot. Pools often clash with drainage lines or easements in newer estates. Include the safety barrier, the gate, the access path and any new paving on one plan instead of adding them as afterthoughts. A pool may suit a complying development certificate (CDC) if every code standard is met.
Will a new alfresco roof affect my stormwater?
Yes, it can. A new roof adds hard surface, changing how much rain is collected and where it ends up. In the Silverdale estate on the old safari park land, stormwater is managed as one integrated system so water leaving the estate is no worse than before, and your lot’s drainage was approved as part of that. The alfresco’s downpipes need to connect into that approved system. Show the roof, downpipes and any new paving together on your plans, and check easements before setting the posts.
