Practical & Stylish Solutions
Retaining walls don’t have to be dull or industrial-looking. Whether you're after a classic block finish, a natural stone aesthetic, or a simple timber look, we can recommend materials that blend seamlessly with your landscape while doing the job they’re built for. Every site is different, and that’s why we assess slope, drainage, and soil conditions before planning the layout and design.

We can also integrate features like steps, garden beds, or drainage channels to maximise both functionality and visual appeal. Whether it’s part of a bigger landscaping project or a standalone build, we’ll take care of everything from prep and excavation to final clean-up—no fuss, no surprises.
FAQ
Everything You Need To Know
What is the purpose of a retaining wall?
Retaining walls hold back soil on sloped or uneven land. They’re used to prevent erosion, stabilise ground levels, create usable space, and protect nearby buildings or gardens. They’re also often included in landscaping projects for both function and appearance.
What materials are best for retaining walls?
Popular materials include concrete blocks, treated timber, natural stone, and brick. The best material depends on the wall’s purpose, required strength, desired look, and your budget. Timber is cost-effective for smaller jobs, while concrete and stone offer more durability for larger, load-bearing structures.
Do I need council approval to build a retaining wall?
It depends on the wall’s height and location. In many areas, council approval is required for walls over 600mm or if they impact drainage, neighbouring properties, or structural support. It’s best to check local regulations or speak with a licensed contractor familiar with the requirements.
