Retaining Walls in Duncraig
An established northern-suburbs pocket inland of Hillarys, on the coastal sand plain either side of Mitchell Freeway.
Retaining wall guidance for Duncraig homeowners - the right material for your site, and whether the WA 0.5 m permit threshold applies to your project. Duncraig sits in Perth's coastal limestone belt, where Tamala limestone-derived sand shapes most retaining decisions, which is the starting point for every material and compliance recommendation on this page.
Retaining Walls Perth Guidance for Duncraig
Duncraig sits inland of the immediate coast but still on Perth's northern coastal sand plain, along the Mitchell Freeway and Marmion Avenue corridor. Blocks here are generally established, mid-density residential rather than beachfront, with retaining needs driven more by split-level geometry than dramatic coastal grade.
As an established northern-suburbs pocket rather than a recent development zone, a fair share of Duncraig's retaining work is repair or upgrade of existing walls rather than fresh builds.
For a typical Duncraig split-level block, limestone remains the cost-effective default for garden and boundary retaining, with post and panel reserved for taller or load-bearing sections near a driveway or extension. Duncraig sits within the City of Joondalup local government area, the same council covering neighbouring Hillarys; the 0.5 m WA exemption threshold and Joondalup's permit process apply consistently across both suburbs, so confirming with the City of Joondalup remains the right first step for any wall over that height.
Because so much of Duncraig was built in a single era, a common enquiry is a like-for-like retaining wall replacement alongside a wider home renovation - in that scenario it is worth checking whether the retaining work itself triggers a fresh permit even when the rest of the renovation is separately approved.

About Duncraig
Duncraig is home to landmarks including Duncraig Senior High School, Marmion Avenue corridor, Mitchell Freeway. Established family housing from the suburb's original development phase makes up much of Duncraig's stock, with retaining enquiries split between upgrades to existing walls and work tied to renovations.
Local context for Duncraig
Duncraig's streets around Marmion Avenue and Warwick Road were largely built out in the suburb's original development phase, and its position inland of the coast but still on sandy ground means the retaining picture here is less about coastal grade and more about the typical split-level blocks common through Perth's established northern corridor.
