Inner West · AS 3660.1
St Peters sits on old brickworks and landfill land now carrying the WestConnex interchange, postcode 2044, and older homes west of the Princes Highway still need proper termite protection.
Quick answer
Yes, a new home or knockdown rebuild in St Peters needs a termite management system under the NCC, since the suburb sits in a termite-prone part of Sydney. The system is installed to AS 3660.1 before the concrete pour, with collars fitted at every penetration. A durable notice for the meter box and an installation certificate for the certifier are both required before the Occupation Certificate.
Termite barriers in St Peters
St Peters is in postcode 2044, about 6.1 km south-west of the CBD, with most of the suburb in the Inner West Council area and a small south-eastern section in the City of Sydney. Housing is concentrated west of the Princes Highway, while land east of the highway was largely industrial until recently, and the northern and western parts along the rail line and Unwins Bridge Road remain mostly industrial today. The eastern end of the M8 and the large WestConnex interchange now sit on old landfill and brickworks land, echoing neighbouring Sydney Park, which was also built on former brickworks. Rebuild work here is concentrated on the older homes west of the highway.
Older homes in St Peters can have timber sub-floors that suit termites, and years of nearby construction have disturbed ground across parts of the suburb, which is exactly the kind of change that can shift existing termite activity onto neighbouring blocks. A rebuild west of the highway needs both of those factors accounted for: the age of the original sub-floor timber, and the extent to which major infrastructure work like the WestConnex interchange has recently reworked the soil close by. We check what's actually happened to the ground before finalising a barrier for any St Peters project.

Local conditions
Three local conditions shape how we detail a barrier in St Peters.
Older homes in St Peters can have timber sub-floors that suit termites, and that's where most of our rebuild work is concentrated. We check existing sub-floor conditions carefully before finalising a new barrier design for any knockdown rebuild here.
Years of construction around the WestConnex interchange and the M8 have disturbed ground across parts of the suburb, and disturbance like that can shift existing termite activity onto blocks nearby. We factor recent construction history into our site assessment.
Parts of St Peters, including land now under the interchange, sit on old brickworks and landfill, much like neighbouring Sydney Park. Ground with that history can behave differently underfoot, which we account for when planning soil preparation.
What we install here
St Peters work is mostly knockdown rebuilds and extensions of the suburb's older homes west of the Princes Highway, with occasional light-industrial or warehouse-conversion slabs closer to the rail line. Waffle pod and raft slabs suit most residential sites. We fit collars to every pipe and conduit penetration and run the perimeter to the true boundary, checking existing sub-floor timber and recent ground disturbance from nearby construction before finalising a design, and we work to your builder's program throughout.
Local knowledge
Sydenham Green sits close to much of our St Peters work, its turf and planting a reminder of how much green space has been reclaimed from the suburb's industrial past. Sydenham station marks the rail corridor that separates the residential streets from the industrial land beyond. Park Sydney Village, a little further out, sits closer to the newer developments on former warehouse land, and across St Peters generally, the legacy of brickworks, landfill and recent road construction shapes ground conditions more than in most Inner West suburbs.
Most of St Peters is certified through Inner West Council, with a small south-eastern section falling under the City of Sydney. Both expect the same two records before an Occupation Certificate follows: a meter-box notice confirming the system, and an installation certificate that lists the products, the treated areas and the installer's licence. We have these ready as soon as our stage of a St Peters job wraps up.

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.

St Peters questions

+61 450 515 215Yes. Older homes here can have timber sub-floors that suit termites, so we check existing sub-floor conditions carefully before recommending a new AS 3660.1 barrier for the rebuild. That check matters more in St Peters than in many Inner West suburbs given how long some of the housing stock has stood.
It can. Years of construction around the interchange and the M8 have disturbed ground across parts of the suburb, and that kind of disturbance can shift existing termite activity toward neighbouring blocks. We factor recent construction history into our assessment before finalising a barrier design for your new build or rebuild.
Most of St Peters is certified through Inner West Council, with a small south-eastern section under the City of Sydney. Both want the identical pair of documents before an Occupation Certificate: a meter-box notice and an installation certificate naming the products, the treated areas and the licensed installer. We prepare both regardless of which side applies.
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.
