Retaining Wall Tips for Sydney

Sydney council requirements for retaining walls are strict — walls over 600 mm often require a Development Application in many LGAs

Sandstone is the traditional Sydney retaining wall material and blends well with the natural landscape — expect a premium price for quality installation

Inner-west and north shore Sydney properties on steep blocks often need engineer-certified walls — factor in $600–$2,300 for certification
