Eastern Suburbs · AS 3660.1
Perimeter barriers and under-slab systems fitted to Point Piper's steep sandstone harbourside blocks, installed before the pour around boatsheds, terraced gardens and every level of the build.
Quick answer
Yes. A rebuild on a Point Piper harbourside block needs an NCC termite management system installed to AS 3660.1. Collars and under-slab work go in before the concrete pour, detailed around retaining walls and any basement level. The durable notice for the meter box and an installation certificate for the Municipality of Woollahra certifier are both needed before the Occupation Certificate is issued.
Termite barriers in Point Piper
Point Piper is a small peninsula suburb on Sydney Harbour in the Municipality of Woollahra, about 3.9 km east of the CBD in postcode 2027. It has only around eleven streets, with Wolseley Road as the main one, and no commercial zone of its own, so residents use Double Bay and Rose Bay for shops. The shoreline includes Seven Shillings Beach with Redleaf Pool, Lady Martin's Beach and Duff Reserve, and the Royal Motor Yacht Club and Royal Prince Edward Yacht Club sit on the water. Our work here is exclusively rebuilds and major renovations on large, established harbourside properties.
Homes on Point Piper are large, many on steep sandstone blocks running down to the harbour, with boatsheds, terraced gardens, pools and extensive landscaping. Those features together create the main termite risks a barrier here has to manage. Retaining walls, irrigated gardens and harbour moisture suit subterranean termites, and mature trees give access toward rooflines well above ground level. Deep basements and plant rooms, common on these larger homes, are quiet spaces where activity can settle undetected if the barrier is not detailed carefully around every level of the build.

Local conditions
Three things shape termite risk on a Point Piper property, tied to the steep sandstone terrain and the scale of the homes.
Many Point Piper properties run down steep sandstone toward the harbour, with terraced gardens and retaining walls linking each level. Every retaining junction and step-down is a place a barrier can be let down if it is improvised, so we work from the engineering drawings and detail those points before work starts.
Boatsheds and gardens close to the harbour edge sit in consistently damp conditions, and that moisture makes it easier for termites to move toward nearby structures. We check timber-to-ground contact around boatsheds and pool surrounds as part of the barrier plan, not as an afterthought.
Larger Point Piper homes often include basement levels and plant rooms below the main living areas, and these quiet, rarely disturbed spaces can let termite activity settle unnoticed. We detail the barrier around every level of the build, not just the ground-floor slab.
What we install here
We work on Point Piper rebuilds and major renovations on large harbourside properties, with barrier systems planned around basements, terraced gardens, boatsheds and pool surrounds alongside the main slab. Suspended floors and piers are common where blocks fall steeply toward the water. You get one fixed written quote from the plans covering the whole property, and we attend around your builder's program so the barrier never holds up the pour.
Local knowledge
Our Point Piper work sits close to Seven Shillings Beach and Rose Bay Park, where salt air and harbour moisture keep sub-floors and basements damper than an inland property. Being such a small peninsula suburb, almost every rebuild we work on has some frontage or proximity to the harbour, so retaining walls and boatshed detailing feature in most of the jobs we do here.
The Municipality of Woollahra certifies Point Piper building work, and before granting an Occupation Certificate it wants a durable notice for the meter box, plus a certificate from the installer covering the products, the coverage and their licence, across every level of the build. We finalise both as soon as our stage of the work is complete.

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.

Point Piper questions

+61 450 515 215The system itself is the same NCC-compliant barrier, but the detailing is more involved. Retaining walls and terraced gardens linking different levels of the block each create a junction where a rushed barrier can leave a gap, so we work from the engineering drawings and price those points before work starts.
Yes. Basements and plant rooms are quiet, rarely disturbed spaces where termite activity can settle unnoticed, so we detail the barrier around every level of the build rather than treating the ground-floor slab as the only point of entry to protect. We plan access for each level separately, since basement work is often staged differently from the ground-floor slab.
Where a boatshed or pool structure has timber-to-ground contact, it needs the same attention as the main house. Harbour-edge moisture keeps these areas consistently damp, which is exactly the condition that draws termites, so we include them in the barrier plan rather than treating them as separate from the main build.
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.
