Baulkham Hills, the original Hills suburb
A mostly residential suburb at the junction of Windsor, Old Northern and Seven Hills roads, with older homes due for new driveways and outdoor areas.
Where three roads meet
Baulkham Hills is about 28 km north-west of the Sydney CBD. It is mostly in The Hills Shire, with a small southern section in the City of Parramatta, and is predominantly residential. Windsor Road, Old Northern Road and Seven Hills Road meet here.

Hills or Parramatta council?
Most of Baulkham Hills is in The Hills Shire, but a small southern section is in the City of Parramatta. The council that owns your road sets the rules for the driveway crossing, so we check which one applies before we quote.
A Baulkham Hills courtyard
The concrete courtyard photo on our site is a Baulkham Hills job. On older homes, replacing tired pavers or cracked slabs with a single, well-drained courtyard makes the outdoor area usable all year round.

What we build here
Driveways and the crossing at the road, carport, garage and granny flat slabs, patios and alfresco areas, pool surrounds, paths and stairs, and decorative finishes.
Excavation included
We do our own cut, fill and base, so one crew handles the job from breaking out the old driveway to the final finish, and one price covers it.
Complete jobs, not patch-ups
Whole driveways, whole patios, whole pool surrounds — where we control preparation, pour and finish rather than patching someone else’s work.
What’s under a Baulkham Hills driveway?
Baulkham Hills sits on the shale country of the Cumberland Plain, and reactive clay is the thing that decides how much preparation a driveway or slab actually needs.
Shale clay soils
Baulkham Hills sits on the Wianamatta Group shales of the Cumberland Plain. The NSW Government’s soil landscape report for this area describes the Blacktown soil landscape as gently undulating rises on Wianamatta Group shales, with a moderately reactive, highly plastic subsoil and poor soil drainage.
Source: NSW Department of Climate Change, Energy, the Environment and Water, Soil Landscapes of the Sydney region, Blacktown (bt) unit
Reactive ground moves
Reactive clay swells when it takes up moisture and shrinks as it dries. AS 2870, the Australian Standard for residential slabs and footings, classifies sites by how much that movement is expected: Class A and S are stable to slightly reactive, M moderately, H1 and H2 highly, and E extremely. The more reactive the ground, the more the slab design has to allow for it.
Source: AS 2870 Residential slabs and footings, AS 3600 Concrete structures, and the National Construction Code
What that means for your block
A site classification under AS 2870 comes from a geotechnical soil test on your property, not from a suburb map, and no honest quote assigns one without it. What we can do is look at the ground when we quote, and tell you where the preparation is going to matter.
Every block is different. A classification for your property comes from a soil test.
Which council is your Baulkham Hills block in?
The Hills Shire and the City of Parramatta both name this suburb, a legacy of the 2016 boundary change. The two run different crossing rules.
Both lists name it
The NSW Electoral Commission lists Baulkham Hills among the localities included wholly or partly in The Hills Shire, and also among those included wholly or partly in the City of Parramatta. The 2016 boundary change moved part of this area out of The Hills. Your rates notice, or a section 10.7 planning certificate, names the council that assesses your block.

Under The Hills
A Vehicular Crossing Request lodged online, paid before residential work commences. The applicant supplies the contractor’s details and a copy of their public liability policy, to a $10 million minimum, and council requires them to be appropriately skilled and experienced. Two inspections — one before any concrete is poured, one at completion — on 24 hours notice.
Source: The Hills Shire Council, Driveways — Vehicular Crossing Request
Under the City of Parramatta
An application and payment of inspection fees before any construction starts. Concrete is no less than 25 MPa at 28 days with a broomed or wood float finish. A residential crossing is between 3.0 and 5.5 metres wide, and the number of crossings is limited to one per property with frontages up to 18 metres, and two where the frontage exceeds 18 metres. Council’s Asset Inspector needs a minimum 24 hours notice for formwork inspections.

Driveway approvals in Baulkham Hills
A new driveway almost always includes the crossing between the road and your boundary. In Baulkham Hills, the first question is not how it gets built — it is which of two councils assesses it.
First, find out whose it is
The NSW Electoral Commission lists this suburb among the localities included wholly or partly in The Hills Shire, and also among those included wholly or partly in the City of Parramatta — a legacy of the 2016 boundary change. Your rates notice or section 10.7 planning certificate settles it for your block.

Local FAQs
Anything else, call 0468 491 882.
Do you do concreting in Baulkham Hills?
Yes. We build driveways and crossings, carport, garage and granny flat slabs, patios, pool surrounds, paths, stairs and decorative concrete for homes in Baulkham Hills and nearby suburbs, including Castle Hill, Winston Hills, North Rocks and West Pennant Hills.
Can you replace old pavers with a concrete courtyard in Baulkham Hills?
Yes. We lift the pavers, rebuild the base and pour a concrete courtyard with falls away from the house, finished in whatever suits the home, from broom to exposed aggregate.
Do I need council approval for a driveway crossing in Baulkham Hills?
Yes — and the first question is which council. The NSW Electoral Commission lists Baulkham Hills among the localities included wholly or partly in The Hills Shire, and also among those included wholly or partly in the City of Parramatta, a legacy of the 2016 boundary change. Your rates notice or your section 10.7 planning certificate names the council that assesses your block.
What are the two specifications?
Under The Hills: A Vehicular Crossing Request lodged online with payment before residential work commences, the contractor’s details and a copy of their public liability policy to a $10 million minimum, and two inspections — one before any concrete is poured and one at completion — on 24 hours notice. Under the City of Parramatta: An application and payment of inspection fees before construction starts. Concrete no less than 25 MPa at 28 days with a broomed or wood float finish, a residential crossing between 3.0 and 5.5 metres wide, one crossing per property with frontages up to 18 metres and two where the frontage exceeds 18 metres, and a minimum 24 hours notice to council’s Asset Inspector for formwork inspections.
Can I have two driveways?
Under the City of Parramatta, the number of crossings is limited to one per property with frontages up to 18 metres, and two where the frontage exceeds 18 metres. If your block is assessed by The Hills instead, that is a different application with different rules, so check your rates notice before you plan a second crossing.
How much does a concrete driveway cost in Baulkham Hills?
It depends on the size, how much excavation and base preparation the ground needs, whether an old driveway comes out, the crossing at the road, and the finish you choose. On an established block, what is under the old surface is usually the variable. The accurate number comes from seeing the site, and quotes are free.
What kind of ground is a Baulkham Hills driveway built on?
The Hills District sits on the Wianamatta Group shales of the Cumberland Plain, and reactive clay swells and shrinks with moisture, so base preparation and reinforcement matter more than they would on stable ground. Your block’s actual site classification under AS 2870 comes from a geotechnical soil test, not from a suburb map. On an established block the bigger unknown is usually what is under the old driveway — fill, a broken-up sub-base, or tree roots.
Is Baulkham Hills in The Hills Shire or the City of Parramatta?
Both lists name it. The NSW Electoral Commission lists Baulkham Hills among the localities included wholly or partly in The Hills Shire, and also among those included wholly or partly in the City of Parramatta — the 2016 boundary change moved part of the suburb. Most of Baulkham Hills is The Hills, but the southern edge is not, and the two councils run different crossing processes. Your rates notice settles it.
Are you licensed and insured?
Yes. Southo Concrete holds NSW contractor licence 398552C and a general construction induction white card, and carries $20 million public and product liability cover plus workers insurance. Certificates of currency are available on request, along with SWMS where a site needs them, and we can complete site inductions as required.
How long will the concrete last, and will it crack?
We use high-quality materials and proven construction methods to help ensure our work lasts for 25 years or more. We also use appropriate materials and techniques to control cracking in our slabs, helping to keep it very limited, if not eliminate it altogether. Please note that cracking can be affected by factors outside our control, including ground movement, weather and site conditions.
Do you do small concrete repairs in Baulkham Hills?
No. We take on complete jobs — driveways, carport and garage slabs, patios, pool surrounds and paths — where we control the work from preparation through to finish. We don’t do small patch-up repairs.
