Penrith & the Outer West · AS 3660.1
Perimeter barriers and under-slab systems fitted to Orchard Hills acreage blocks and new homes, installed before the pour on land once planted with the orchards and vineyards the suburb is named for.
Quick answer
Yes. A new home or shed-adjacent build on an Orchard Hills property needs an NCC termite management system installed to AS 3660.1. Collars and under-slab work go in after the plumber's rough-in and before the pour. The durable notice for the meter box and an installation certificate for the City of Penrith certifier are both required before the Occupation Certificate is issued.
Termite barriers in Orchard Hills
Orchard Hills is a rural suburb in the City of Penrith, postcode 2748, about 44 km west of the CBD. Its name comes from the orchards planted on its rolling hills around 1900, after the old York Estate was subdivided into orchards and vineyards in the late 1880s. It still has a mostly rural character, with fruit trees, grapevines and acreage homes alongside some newer housing, and Mamre, a Colonial Georgian sandstone homestead built for Reverend Samuel Marsden around 1830, still stands in the suburb. A station on the planned Western Sydney Airport metro line will bring more building activity in the years ahead.
Ground that has grown fruit trees and vines for well over a century behaves differently from a cleared suburban block. Old root systems, buried orchard stock and long-cultivated soil can all give subterranean termites material to work with before a new slab ever goes down, so soil preparation matters as much as the barrier itself on an Orchard Hills build. Large sheds, water tanks and acreage outbuildings common on these properties also add timber-to-ground contact well beyond the house footprint, so we treat the whole property as part of the job, not just the main slab.

Local conditions
Three things shape termite risk on an Orchard Hills property, tied to its rural history and acreage layout.
Land that grew fruit trees and grapevines for over a century, since the old York Estate was subdivided in the 1880s, often carries old root systems and cultivated soil that can feed termite activity. We treat soil preparation ahead of the slab as seriously as the perimeter barrier around it.
Acreage properties in Orchard Hills commonly carry large sheds, water tanks and other outbuildings with their own timber-to-ground contact points, well beyond the main house footprint. We plan the barrier around the whole property and how it is used, not just the slab under the house.
With a station planned on the Western Sydney Airport metro line, newer housing is starting to appear alongside the suburb's acreage blocks. New builds on recently subdivided rural land still need a full termite management system, since fresh clearing can disturb activity that was previously settled in old orchard rows.
What we install here
We work on Orchard Hills new homes, acreage rebuilds, sheds and outbuildings, and the newer housing appearing as the suburb grows around the planned metro station. Suspended floors and piers turn up on larger rural-residential blocks, alongside waffle pod slabs on newer, more conventional builds. 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 Orchard Hills work covers acreage properties near Orchard Hills Golf Club, where irrigated turf and water features add moisture to the surrounding land, and blocks closer to Mulgoa Nature Reserve, where bushland edges bring the same perimeter attention we would give a bush-fringed suburb further east. Around Glenmore Village, sites are more often newer housing on recently subdivided land.
The City of Penrith wants a durable notice in the meter box and a signed certificate from the installer, listing the products, the coverage and the licence held, before it will issue an Occupation Certificate for an Orchard Hills property. We deliver both as soon as our stage of the job wraps up, whether the build is on acreage or a standard residential block.

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

Orchard Hills questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Often yes. Ground that grew fruit trees and vines for well over a century can carry old root systems and cultivated soil that give termites material to work with before a slab is even poured. We check the soil on former orchard blocks and treat it properly ahead of the under-slab system.
Where a shed or outbuilding has habitable use or is close to the house, its timber-to-ground contact points need the same attention as the main slab. We plan the barrier around the whole property, including outbuildings, rather than treating the house as the only thing that matters. Larger properties sometimes have more than one shed, so we confirm the full list before quoting.
Yes, every new home in a termite-prone area needs an NCC-compliant termite management system regardless of how recently the land was subdivided. Newly cleared land near the planned station can actually push displaced activity from old orchard rows toward fresh timber-framed housing, so the barrier matters from the first pour.
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.
