Inner West · AS 3660.1
Perimeter and under-slab barriers installed to AS 3660.1 for knockdown rebuilds and secondary dwellings on Lilyfield's narrow cottage blocks, from the Whites Creek corridor to the grounds of Callan Park.
Quick answer
Yes, a rebuild or new secondary dwelling in Lilyfield needs a termite management system, because the suburb is in a termite-prone part of the Inner West Council area and the NCC applies regardless of the block's age or size. The system is installed to AS 3660.1, with collars and under-slab work going in before the pour, and the durable notice and installation certificate handed to your certifier before.
Termite barriers in Lilyfield
Lilyfield sits about 4 km west of the Sydney CBD in postcode 2040, within Inner West Council, and began as a working-class pocket of small workers' cottages, many of which are now being knocked down and rebuilt or extended behind their original street frontage. Iron Cove and the Bay Run form the suburb's western boundary, Whites Creek runs north toward White Bay, and the light rail follows a former goods line through the middle of the suburb, with the City West Link carrying heavy traffic across it toward the Anzac Bridge. Most of our work here is a rebuild on a narrow inner-west block or a granny flat in a small rear yard.
Callan Park, the former hospital grounds with its sandstone Kirkbride buildings and large areas of old trees and lawn, is the suburb's biggest single piece of ground, and mature grounds like that hold established termite activity in old stumps and fallen timber close to nearby streets. Whites Creek and the foreshore land toward Iron Cove keep soil damp along the western edge, and Lilyfield's older cottages sit on narrow side paths with timber sub-floors that can already carry termite activity before a rebuild starts. On a block this tight, the barrier has to be planned around party walls and a slab edge that rarely runs in a straight line.

Local conditions
Three local conditions shape a Lilyfield barrier more than the size of the block does.
Callan Park's sandstone buildings sit within large areas of old trees and lawn that hold established termite colonies in stumps and fallen timber. Rebuild sites within a few streets of the park get a full perimeter rather than a minimal treated strip.
Whites Creek and the low-lying land toward Iron Cove keep soil damp along Lilyfield's western edge, and damp ground close to a slab is what subterranean termites look for when foraging from the foreshore. We detail those boundaries with extra care.
Lilyfield's workers' cottages often sit on narrow blocks with timber sub-floors and side paths built hard against the boundary, and that old timber can carry termite activity long before a rebuild is even planned. We check the neighbouring structure as part of every quote.
What we install here
Most of our Lilyfield work is a knockdown rebuild behind a retained cottage frontage, a granny flat in a tight rear yard, or an extension that ties new slab into an old sub-floor. We install under-slab membrane, collars and a physical or chemical perimeter suited to narrow, party-wall blocks, working in stages so a barrier visit fits around your builder's plumbing rough-in and pour date. One fixed quote from your plans covers the whole job.
Local knowledge
A good share of our Lilyfield work sits within a few streets of Callan Park, where old trees and sandstone grounds run close to residential boundaries, and along Whites Creek toward Iron Cove and the Bay Run, where foreshore land keeps soil damp. Around Lilyfield station and Norton Plaza, rebuild sites are more often narrow cottage blocks with a party wall on one or both sides, and Leichhardt Oval marks the southern edge of our usual run.
Lilyfield sits entirely within the Inner West Council area, which certifies rebuilds, granny flats and any new dwelling in the suburb. Before issuing the Occupation Certificate, the certifier needs a durable notice fixed in the meter box and an installation certificate naming the products used, the areas protected and the installer's licence. We supply both, together with product data and maintenance advice, as soon as the barrier work is finished.

Systems we install
Every photo below is from one of our own Sydney jobs. We look at your slab design, site and budget, then recommend a system or a combination.
01A termite-resistant sheet laid over the whole prepared footprint before concreting, so termites can't come up through the slab anywhere.
02A sealed collar on every pipe, conduit and service that passes through the slab. These gaps are the most common hidden way in.
03Protection at the slab edge and into the wall cavity, which stops termites building hidden tunnels up the outside of the slab.
04An APVMA-registered termiticide zone in the soil, with an optional pipe network under paving so it can be recharged later without digging.
05Barriers for bearers, piers and raised timber floors on sloping or elevated blocks, where there's no slab to protect.
06Detailing for sandstone cuts, block retaining walls, step-downs and cut-and-fill sites, which are common across Sydney.
Why during construction
A retrofit can only treat around a finished house. A pre-construction system protects the parts nobody will ever be able to reach again.
A barrier put in during the build costs a fraction of a post-construction system, and far less than repairing termite damage.
New houses (Class 1) and outbuildings (Class 10) with termite-susceptible framing need a compliant termite management system.
Pipe penetrations and slab joints can only be fully protected while they're still open, before the concrete goes in.
An under-slab system covers ground that no treatment from outside the finished house can ever reach.
Your certifier needs the certificate and durable notice before issuing the Occupation Certificate. We supply both together.
Documented, compliant protection gives buyers, building inspectors and lenders confidence when the home is sold.
Installation stages
A termite barrier isn't a single visit. Each part goes in when the site is ready for it, and we fit around your plumber, concreter and bricklayer.
Send your plans and slab details. We recommend a system and give you one fixed price that covers every stage.
Collars go on every service once the plumber has set out, then the membrane or soil treatment is installed across the prepared site.
Perimeter and cavity protection is fitted as the brickwork or cladding goes up, so there's no unprotected gap at the slab edge.
Where it's specified, the chemical perimeter or reticulation system is completed around the building before paths and gardens go in.
A durable notice goes in the meter box, and the installation certificate goes to your builder and certifier.
The owner gets simple care instructions and an inspection schedule so the system keeps doing its job for years.
Compare systems
Both can meet AS 3660.1. The best choice depends on your slab type, what surrounds the house and how much ongoing upkeep the owner wants.
Physical protection
Entry-point protection
Soil protection
Top-up protection
Most of the Sydney builds we work on use a combination: physical collars on every penetration plus a physical or chemical perimeter.
For builders & developers
Builders, developers and owner-builders get a fixed quote from plans, a technician who turns up when the site is ready, and paperwork that never holds up sign-off.
Consistent pricing across lots, one point of contact and a full document set for every dwelling.
Missing durable notices and unclear install records are a common reason Occupation Certificates get held up. We hand everything over together so your certifier has it all in one go.
Paperwork

Lilyfield questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Yes. A secondary dwelling is treated the same as a new home under the NCC, so it needs its own compliant termite management system even on a tight rear yard. We detail the perimeter around fences, party walls and any existing structure so nothing is left as a gap. This keeps everything properly documented for future reference too.
It does. The park's old trees and grounds hold established termite activity, so rebuild sites within a few streets usually get a full physical perimeter rather than a minimal strip. We are happy to look at the boundary facing the park as part of your quote. Just get in touch and we will talk through the details.
After the plumber has roughed in the drainage and before the concrete is poured, the same as any other new slab. On a narrow inner-west block we also plan around scaffolding and limited site access, so let us know those constraints when you book. We treat every quote as specific to your actual block.
In most cases, yes. The National Construction Code requires a termite management system for new houses and outbuildings in termite-prone areas where the primary building elements can be damaged by termites. Sydney is termite-prone, so the system is installed to AS 3660.1 and your certifier asks for the installation certificate and durable notice before the Occupation Certificate is issued.
It depends on slab area, perimeter length, the number of pipe penetrations, the system chosen, site complexity and how many visits the build needs. Send us the plans and we return one fixed written quote covering every stage. Quoting is free.
