Eastern Suburbs · AS 3660.1
Boutique barrier installation for Elizabeth Bay 2011 apartment and villa rebuilds among the Art Deco blocks and Victorian Italianate houses near Elizabeth Bay House and Boomerang.
Quick answer
Yes. Elizabeth Bay lies within a termite-prone part of Sydney, so a new dwelling or a substantial rebuild here needs a compliant termite management system under national building rules. Fitting it to the AS 3660.1 standard has to happen before the slab goes down. Your certifier then needs a durable notice stored inside the meter box, plus an installation certificate on file, before the Occupation Certificate is released.
Termite barriers in Elizabeth Bay
Elizabeth Bay, also known by its Aboriginal name Gurrajin, is a small harbourside City of Sydney suburb about 1.8 km east of the CBD in postcode 2011, its streets tightly packed with Art Deco apartment buildings such as the 1937 Edgewater flats alongside heritage landmarks including Elizabeth Bay House and the Spanish Mission estate Boomerang, with Victorian Italianate villas from the 1860s and 1870s further back from the water. There is next to no vacant land, so new work is almost always a heritage-sensitive apartment rebuild, a boutique infill development, or a villa renovation on one of the older streets.
A suburb built this densely, this close to the harbour, needs a barrier plan built around the site rather than a standard layout. Light wells, shared basements and party walls between neighbouring blocks all affect where collars and perimeter treatment can physically be installed, and the moisture that hangs around a harbourside block rarely lets the ground dry out the way it would further inland. Getting the detailing right before a heritage-area pour matters more here than almost anywhere else we work, since access rarely allows for a second attempt later on, once scaffolding comes down and the building is handed back to its owners.

Local conditions
Three things shape how a barrier gets fitted in Elizabeth Bay.
With Art Deco blocks and Victorian villas built almost wall to wall, nearly every job is a rebuild or boutique infill rather than a new estate. Each site needs its own collar and perimeter plan around existing party walls and light wells.
Sitting right on the harbour means the ground around a slab or basement level rarely dries out the way an inland site would, and that ongoing dampness suits subterranean termites wherever a barrier has a weak point at a penetration or slab joint.
Apartment rebuilds here often involve a basement or lower ground level close to a neighbouring foundation, so collars and perimeter treatment have to be detailed around structural elements rather than a simple open slab edge.
What we install here
Our Elizabeth Bay work is almost entirely heritage-area apartment rebuilds, boutique infill and villa renovations rather than anything close to estate-scale building, given how little room the suburb has left. We fit collars, membrane and perimeter treatment around basements, light wells and party walls, working with heritage consultants and builders on tight sites, and the visit is timed against the plumber's rough-in so the barrier fits a constrained inner-city program.
Local knowledge
John Armstrong Reserve sits close to the harbour edge near many Elizabeth Bay apartment blocks, with Kings Cross station a short walk away bringing its own dense, mixed-use surrounds. Sites nearest the harbour get the closest attention to slab and basement-level detailing given the added humidity, while blocks near Elizabeth Bay House and the older villa streets tend to carry more heritage constraints on where a barrier can be placed.
City of Sydney certifiers handle new dwellings and substantial rebuilds in Elizabeth Bay. What they need before releasing the Occupation Certificate is straightforward: a durable notice recording the system inside the meter box, and a matching installation certificate confirming exactly what was fitted and where it protects the building. Both documents are ready once the barrier is installed, along with the relevant product data sheets.

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.

+61 450 515 215Yes, though the approach is tailored to what heritage constraints allow. We work with heritage consultants and builders to place collars and perimeter treatment without affecting protected fabric, and we detail carefully around any basement or light well close to the original structure, agreeing the exact placement with the consultant before any work starts on site.
Ground near the harbour tends to stay damper for longer than an inland block, which can support termite activity close to a slab or basement level. We pay particular attention to penetrations and slab joints on lower floors to make sure the system has no gap for that moisture to exploit.
We count every penetration across the shared slab, fit collars to each one, and run the perimeter continuously around the building footprint, working around party walls and any basement level. Visits are scheduled to the plumber's rough-in so the barrier fits a tight inner-city build program without holding up the next trade 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.
