⚖️ QLD Council Regulations & Permits

Before commencing your landscaping project, it is essential to know the local building codes. In the Brisbane City Council (BCC) area and most of South East Queensland, retaining walls are generally considered accepted development (no permit required) IF they meet these strict criteria:

  • Height Limit: The total height of the wall and the fill or cut is no more than 1 metre (1000mm).
  • Boundary Rules: It is no closer than 1.5 metres to a building or another retaining wall.
  • Surcharge Loads: It does not carry any "surcharge" loads (such as a driveway, pool, or heavy structure above the wall).

Building Over 1 Metre?

If your retaining wall exceeds 1000mm or takes a surcharge load, you will legally require a building approval and a design certified by an RPEQ (Registered Professional Engineer of Queensland). All of our concrete sleepers are AS3600 certified, making the engineering sign-off process seamless for your project.

Disclaimer: Regulations can vary slightly between councils (e.g., BCC, Logan, Moreton Bay). Always consult your local council or a private certifier before building.

Brisbane Retaining Wall FAQs for Builders

Do I need council approval for a retaining wall in Brisbane?

Under Brisbane City Council (BCC) regulations, retaining walls generally do not require building approval if the total height is less than 1 metre, they are set back at least 1.5 metres from buildings and boundaries, and they do not support surcharge loads like driveways. Walls over 1 metre require a building permit and an RPEQ (Registered Professional Engineer of Queensland) certified design.

Are your products suitable for Queensland weather and termites?

Absolutely. Unlike timber walls that rot in the wet QLD summers or attract termites, our concrete sleepers are 100% termite-proof and weather-resistant. Combined with our hot-dipped galvanised steel posts (AS4680 compliant), they are engineered to last 50+ years in South East Queensland conditions.

Where do you deliver in South East Queensland?

We supply heavy-duty crane truck and forklift deliveries across the entire Greater Brisbane region. Our logistics network regularly services trade sites from the Gold Coast up to the Sunshine Coast, and inland through Logan and Ipswich.
