Inner South & City Fringe · AS 3660.1
Collars, membrane and party-wall detailing fitted to Redfern's terrace rebuilds and apartment slabs, installed before the pour close to the major transport hub at Redfern station.
Quick answer
Yes. A rebuilt terrace or new apartment building in Redfern still needs an NCC termite management system installed to AS 3660.1. Collars and under-slab work go in before the concrete pour, detailed around shared party walls or multi-dwelling penetrations. The durable notice for the meter box and an installation certificate for the City of Sydney certifier are both needed before the Occupation Certificate.
Termite barriers in Redfern
Redfern is an inner southern suburb in the City of Sydney, about 2.6 km south of the CBD in postcode 2016. It has many examples of Victorian terraced housing, similar to Surry Hills and Paddington, alongside modern apartment buildings, and flats now make up most homes in the suburb. Redfern station is a major transport hub and the first stop south of Central, and the suburb has deep significance for Sydney's Aboriginal community. Our work here spans terrace rebuilds on the older streets and apartment construction near the station precinct.
Redfern's shift from almost entirely Victorian terraces to a mix of terraces and modern apartments means a termite barrier here can be either job, sometimes on the same street. Terrace rebuilds need the same careful detailing around shared party walls that any inner-city row demands, since a colony active next door sits right against the new footings. Apartment developments near the station and the wider rail corridor carry a different scale of construction, with basement or podium slabs and a much higher number of service penetrations to collar on a single pour.

Local conditions
Three things shape termite risk in Redfern, tied to its terrace rows and its apartment construction near the station.
Redfern's Victorian terraces share walls and often roof space, so a colony active in one house can already be pressing against the footings of the next. We detail the barrier hard against that party wall junction on any terrace rebuild rather than treating it as an isolated slab.
New apartment buildings close to Redfern station and the rail corridor often carry basement or podium slabs with a large number of service penetrations. Collar counts and scheduling around the builder's program drive both the price and the timing on sites like these.
Even where a Redfern property is not a terrace, inner-city lots here tend to be narrow with limited external access. We plan collar layout and membrane runs from the plans before we arrive, working around whatever access the site actually has.
What we install here
We work on Redfern terrace rebuilds, rear and side extensions, and apartment and mixed-use developments near the station precinct. Slabs on terrace sites are usually small and constrained by party walls, while apartment sites need collar counts planned from the plans well before we arrive. You get one fixed written quote covering every stage, and we work around narrow-lot access and your builder's sequencing so the barrier is never the thing holding up the build.
Local knowledge
Most of our Redfern work sits near Great Buckingham Street Reserve and Jack Floyd Reserve, where terrace rebuilds and rear-lane access shape the job, and toward the Central Grand Concourse precinct, where larger apartment and mixed-use construction drives collar scheduling. Rail corridors and drains through this part of the suburb are a factor we check on any slab running near the fence line.
The City of Sydney will not issue an Occupation Certificate for a Redfern build without a durable meter-box notice and a certificate from the installer naming the products, the coverage and the licence held. We finalise both as soon as our stage of the work wraps up, on a terrace rebuild or an apartment development alike.

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
A complete document set for the builder, the certifier and every future owner of the property.
A permanent notice in the meter box showing the system, install date, installer, any chemical's life expectancy and inspection advice.

Redfern questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Yes. A rebuilt or substantially extended terrace is treated as new work under the NCC, so it needs its own termite management system installed to AS 3660.1, detailed hard against any shared party wall. We check what protection, if any, the original terrace has before finalising the plan. We also confirm access arrangements with any neighbouring property before starting work.
The same NCC requirement applies, but the job is scaled differently. A basement or podium slab near the station can carry many more service penetrations than a single terrace, so collar counts and scheduling around a busy construction program matter more here. We coordinate lift and loading dock access with the builder well ahead of our scheduled visit to the site.
We plan the collar layout and membrane runs from the plans before we arrive, working around whatever access the site has, often just the front or rear lane. On tight sites we sequence our visit closely with the plumber's rough-in and the concreter, since there is usually only one practical window before the slab is poured.
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.
