Stoneville sits on the plateau between Parkerville and Mount Helena, large blocks under jarrah and marri, and one of the hills localities the Shire of Mundaring's strategy names in its own right. We connect you with builders who cover the 6081 area.
Common wall situations in Stoneville
Acreage retaining work: driveway cuttings, house and shed pads, track and dam batters, and terracing that turns a slope into something you can use. The scale is larger than a town wall and the access is usually better, which changes how a quote is put together.
The Shire's strategy records reticulated sewerage in the hills as limited to the Mundaring town centre, so properties here run their own systems and the tank, leach drains and irrigation area are part of the site plan.
The ground under Stoneville
Perth is a sand city. Up here it is not. The ground is ironstone and laterite gravel over weathered granite, and the City of Kalamunda records in its Local Planning Strategy that reticulated sewerage is constrained in the Hills because hard granite sits close to the surface and is costly to dig through. That same rock is what a post hole has to get through, so ask any builder how the quote prices a hole that hits it.
Drainage is the thing that actually matters. Water that cannot soak away through rock travels sideways and arrives behind the wall, and the Shire of Mundaring names heavy soils and perched water tables as Hills constraints for that reason. Ag-pipe, free draining gravel, geotextile fabric and a lawful discharge point are not optional line items.
What a wall costs in Stoneville
As a rough guide, most residential walls run from around $200 to $700 or more per metre for a wall about a metre high, depending on material, height, access and engineering. Those are published Australian guide figures rather than a quote, and rock is the reason a Hills number can sit above them. Read the retaining wall cost guide and then get a price for your block.
Approval, and who to ask in Stoneville
In WA a retaining wall is exempt from needing a building permit only where it retains no more than 500mm of ground, is not tied to other building work or to holding up the land next door, and is not work of a kind that affects adjoining land. The measurement is the ground the wall retains, not the height of the wall, which catches a lot of people out. All three conditions have to be met, so a wall on or near a boundary needs a permit whatever its height. Development approval under the local planning scheme can be a separate question again, and the rules change, so confirm your wall with the Shire of Mundaring before you build.
Who is allowed to build it is a statutory question in WA, and it turns on how the work is classified under the building legislation rather than on a figure you can look up and apply yourself. We are not going to settle that on a web page. What is worth doing is simple: ask the builder what registration or licence they hold, check it with Building and Energy, and ask your permit authority what your particular wall requires before you sign anything. Before any digging, your builder should lodge a free Before You Dig Australia (BYDA) enquiry so underground services are located.
Frequently asked questions
What is the most common wall out here?
Concrete sleeper for driveway and pad work, because it is quick to build at height and the posts do the structural job. Large limestone or interlocking block where the finish matters.
Will rock be a problem?
Possibly, and it is worth pricing for. The granite under the Hills sits close enough to the surface that the City of Kalamunda cites it as a reason sewerage is costly here, and it is the same rock your post holes meet.
Do I need a permit for a pad wall?
A wall associated with other building work falls outside the 500mm exemption at any height, so a pad wall for a shed or a house almost certainly needs a building permit. Confirm with the Shire of Mundaring.
