Inner West · AS 3660.1
Collars and perimeter membrane fitted before the concrete pour for Ashbury 2193 bungalow rebuilds and extensions within the suburb's heritage conservation area near Peace Park's high ground.
Quick answer
Heritage listing does not change the answer for Ashbury: a rebuild or new structure still needs a compliant termite system before the certifier will release an Occupation Certificate. The NCC ties that to AS 3660.1, installed before the slab closes, regardless of the conservation area. Once the work is done we prepare the paperwork, meter-box notice included, for whichever of the two councils is handling your file.
Termite barriers in Ashbury
Ashbury is a quiet residential suburb about 8.9 km south-west of the Sydney CBD, in postcode 2193, split between the City of Canterbury-Bankstown and Inner West Council. Almost the whole suburb is a heritage conservation area, made up mainly of Federation and Californian bungalow houses built between about 1900 and 1940, with leadlight windows, terracotta tile roofs and decorative timber. Peace Park sits on the high ground, and the southern edge of the suburb runs down toward the Cooks River, with rebuild and renovation work on the older bungalow stock making up most of the new construction here.
Those detached houses on garden blocks are what shape termite risk in Ashbury. Bungalows commonly have raised timber floors over a sub-floor, timber verandahs and front fences, and gardens that have grown for decades, all of which suit subterranean termites working quietly toward the house. Because heritage controls encourage owners to keep original timber, a rebuild or extension here often has to protect both a new slab and the sub-floor void of a retained section, and getting the barrier right before the new concrete closes up matters more than it would on a standard suburban block.

Local conditions
Three things matter most for a compliant barrier on an Ashbury heritage block.
Federation and Californian bungalows built between 1900 and 1940 dominate the suburb, and rebuild or extension work on them has to detail a new slab against original raised timber floors and sub-floor voids that heritage controls often require owners to retain.
Bungalow gardens in Ashbury have had many decades to establish, and timber verandahs, front fences and mature planting close to the house all offer a hidden path right up to the frame. Any new slab has to be treated with that established landscaping in mind, not just the bare footprint.
The suburb's southern edge falls away toward the Cooks River, and any new slab or extension on that lower ground needs the perimeter detailed carefully at each step-down, the same as on any other sloping site nearby.
What we install here
We work on Ashbury bungalow rebuilds, rear extensions and the occasional new secondary dwelling, almost all of it inside the heritage conservation area. Waffle pod and raft slabs are common for new sections, while retained sub-floor voids on original bungalows need their own inspection and treatment alongside the new work. Pricing is quoted once from the plans, and we schedule around the plumber's rough-in so a heritage-sensitive build is never left waiting on the barrier.
Local knowledge
Jobs near Peace Park, on the suburb's higher ground, are mostly bungalow rebuilds and extensions where retained timber and established gardens are the main things we check. Closer to the Cooks River on the southern edge, sloping blocks add step-downs that need careful perimeter detailing. James Foster Reserve and Graham Reserve sit within the suburb too, and older garden beds near either one are worth checking on any block backing onto them.
Ashbury straddles the City of Canterbury-Bankstown and Inner West Council depending on which side of the suburb a block sits, and both expect the same two things before signing an Occupation Certificate: permanent signage inside the meter box, and paperwork recording the products, protected areas and installer's licence. On heritage properties we also note how the new work relates to any retained original structure.

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

Ashbury questions

+61 450 515 215No, the NCC termite management requirement applies regardless of heritage status, though a heritage conservation area can affect how a rebuild or extension is designed around retained original timber. We work with your builder to detail the barrier so it protects both the new slab and any sub-floor void that heritage controls require you to keep.
We inspect the raised timber floor, sub-floor ventilation and any timber verandah or fence close to the house for existing termite activity or damage, since a new extension's slab has to tie into that structure without leaving a gap. Decades-old garden beds against the original footings are a common area of concern.
Yes, any step-down or change in slab level toward the lower, southern part of the suburb needs the perimeter detailed carefully at each junction, the same as on any sloping site elsewhere. We work from the engineering plans to make sure those transitions are covered before installation starts on site.
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.
