Swan View sits at the western edge of the scarp and is named on the primary record among the localities doing so. It also sits near where the Shire of Mundaring and the City of Swan meet, which matters when you go looking for your permit authority. We connect you with builders who cover the 6056 area.
Common wall situations in Swan View
Blocks that step toward the scarp, 1960s and 1970s stock, and plenty of walls at the end of their life. The work is terracing, driveway cuttings and edges, and replacing walls built without drainage.
The Shire of Mundaring's strategy named Swan View among the foothills suburbs with unsewered residential areas and recommended lobbying for reticulated sewerage to be extended to them, so both situations exist here. Where a property runs its own system, the tank, the leach drains and the irrigation area constrain the wall line and its drainage.
The ground under Swan View
The substrate is the thing that makes a quote here different from a quote on the plain. Lateritic gravel and ironstone over weathered granite, with the rock close enough to the surface that the City of Kalamunda cites it in writing as the reason sewerage is costly to run through the Hills. Post holes can hit it, and that changes the method, the machine and the price.
Ask what the quote includes behind the wall. Ag-pipe at the base, free draining gravel rather than the spoil that came out of the hole, geotextile fabric so the drain cannot silt up, and somewhere lawful for the water to go. Water, not weight, is what fails walls here.
What a wall costs in Swan View
Published Australian cost guides put a wall about a metre high somewhere between roughly $200 per metre for timber and $700 or more per metre for stone and engineered block. Treat that as a band to sanity-check a quote against, not a price. The retaining wall cost guide explains what moves it here, rock included.
Approval, and who to ask in Swan View
The WA permit line is 500mm, and it is measured as the ground the wall retains rather than the height of the wall itself. The exemption also requires that the wall is not associated with other building work or with holding up the land next door, and is not work of a kind affecting adjoining land. Fail any one of those and a building permit is needed at any height, which is why boundary walls almost always need one. Development approval can be a separate question. the Shire of Mundaring and the City of Swan is the permit authority here, so check your wall with them first.
On who may carry out the work, WA draws the line by how the work is classified under the building legislation, not by a dollar threshold a homeowner can apply to their own job, and the position for a standalone retaining wall is not something to take from a website. Ask any builder what registration or licence they hold and verify it with Building and Energy, and ask your permit authority what your wall requires. Have the builder lodge a free Before You Dig Australia (BYDA) enquiry before anything is dug.
Frequently asked questions
Which council is Swan View in?
This is worth confirming rather than assuming. Swan View sits around where the Shire of Mundaring and the City of Swan meet, and the local government is your permit authority, so establish which one covers your address before you lodge anything.
Is Swan View on a slope?
Yes. It is one of the localities named on the primary record as sitting at the Darling Scarp's western edge.
Is my block on sewer?
Check it. The Shire of Mundaring's strategy named Swan View as having unsewered residential areas and recommended lobbying for sewerage to be extended to them, so it varies by address.
