Retaining Walls in Weston

The centre of Weston Creek

Wikipedia says Weston is a suburb of Canberra with a population of 4,000 at the 2021 census. It says Weston contains the central shopping area of the Weston Creek district, including the Cooleman Court shopping centre, a post office, restaurants, clubs and many specialty shops. The article also lists several churches, Orana School and the Islamic School of Canberra. A suburb with this much activity has a mix of older homes, units and commercial buildings, and a retaining wall job can mean very different things on each.

A name from a homestead

The same article says Weston is named after a homestead built in the area around 1835, and that the Weston Creek grant was once held by Captain Edward Weston, the Superintendent of the Hyde Park Barracks in Sydney. Streets in Weston are named after artists. We mention it because a long-settled district has many older walls, and an older wall is often a repair job, not a new build. Ask each builder how they would assess one before quoting.

Rock close to the surface

The geology section says Deakin Volcanics green grey and purple rhyodacite mostly cover Weston, and describes a large outcrop in the park east of Cooleman Court. It says a band of pink and green porphyry runs across the suburb from west to east and is fault uplifted on the southern side. Hard rock near the surface suits a natural stone wall, and Yakka Labour gives $300 to $700 per square metre for rock walls where machines can reach. Rock can also slow a dig, so ask for an allowance.

Walls beside units and shops

Where a block adjoins shops or a neighbouring building, a retaining wall may carry a load above it. Yakka Labour says any wall supporting a building, a driveway or another wall needs engineering regardless of height. An Access Canberra factsheet says plans must show the actual height of the earth cut that is being retained. Ask whether your quote includes a design and who pays for it.

What the ACT pages say

ACT Planning says a retaining wall does not need a building approval if it is not higher than 1.2 metres, measured from the top of the wall to the lowest adjacent ground level. It publishes separate development approval limits for cut-in and fill walls. Neither page decides your block for you, so read both or ask a building certifier. Access Canberra's register shows whether a builder holds a licence.

Where to start

For a rock or sandstone feature wall, start with our natural stone guide. For a straight wall with a rendered finish or a tight boundary, read the block wall guide.
