Retaining Wall with Fence on Top Ideas

Combine a retaining wall with fencing for privacy, security, and a polished finish. Design ideas, material combinations, and what to consider for Melbourne properties.

Popular Wall + Fence Combinations

Concrete Sleeper Wall + Timber Slat Fence

Concrete Sleeper Wall + Timber Slat Fence

The most popular combination in Melbourne. Steel galvanised posts extend from the concrete sleeper wall upward to support horizontal timber slats. The contrast between the grey concrete and warm timber creates a modern, sophisticated look.

Key consideration: Steel posts must be embedded in the wall footing during construction. Retrofitting a fence is more expensive and less structurally sound.

Concrete Block Wall + Colorbond Fence

Concrete Block Wall + Colorbond Fence

A practical, low-maintenance combination ideal for boundary walls. The concrete block provides structural strength while the Colorbond panels offer complete privacy and weather resistance. Can be colour-matched or contrasted.

Key consideration: Colorbond catches significant wind load. Engineering must account for this, especially on exposed sites or taller combinations.

Retaining Wall + Glass Pool Fence

Retaining Wall + Glass Pool Fence

Required where a retaining wall sits adjacent to a swimming pool. Frameless or semi-frameless glass provides the mandated pool barrier while maintaining sight lines and an open feel. Must comply with AS 1926.1 pool fencing standards.

Key consideration: Glass fence spigots or posts must be core-drilled into the wall capping. The wall cap must be sufficiently wide and strong to support the fencing.

Timber Sleeper Wall + Wire Trellis Fence

Timber Sleeper Wall + Wire Trellis Fence

A budget-friendly and attractive option for garden retaining walls. Stainless steel wire trellis mounted on timber posts above the wall provides a framework for climbing plants, creating a living fence over time.

Key consideration: Wire trellis provides limited privacy until plants establish. Choose fast-growing climbers like star jasmine or hardenbergia for Melbourne conditions.

Sandstone Wall + Aluminium Slat Fence

Sandstone Wall + Aluminium Slat Fence

A premium combination that blends natural stone with modern aluminium. The horizontal aluminium slats complement the horizontal coursing of sandstone, and the powder-coated finish is virtually maintenance-free.

Key consideration: Aluminium slats come in a wide range of colours. Choose a tone that complements rather than competes with the sandstone.

Gabion Wall + Steel Post and Rail Fence

Gabion Wall + Steel Post and Rail Fence

An industrial-inspired combination that works well in contemporary and rural settings. Steel posts extend through or beside the gabion baskets to support horizontal rails, mesh, or timber infill panels.

Key consideration: Steel posts should be concreted beside the gabion baskets, not through them. Galvanised or powder-coated steel prevents rust.

Height Regulations in Victoria

In Victoria, boundary fences on flat ground are generally limited to 2 metres in height without a planning permit. When a retaining wall and fence are combined on a boundary, councils assess the total visual impact from the lower side. A 1 metre retaining wall with a 1.8 metre fence creates a 2.8 metre structure when viewed from the lower property, which may require planning approval.

Always check with your local council and see our council approval guide for details on permit requirements.

Frequently Asked Questions

Does the fence height count towards the retaining wall height for permits?
In Victoria, the retaining wall height and fence height are generally assessed separately for building permits. The retaining wall height is measured from the lower ground level to the top of the wall. However, the combined height of the wall and fence may be subject to planning regulations regarding maximum overall height on boundaries. Always check with your local council.
Can I put a fence on top of any retaining wall?
The retaining wall must be designed to support the additional wind load from a fence. This is especially important for solid fences like Colorbond which catch significant wind. The engineering design should account for the fence as a surcharge load. For walls over 1 metre, the engineer should specify fence post footings and attachment details.
What is the best fence type for a retaining wall?
The best fence type depends on your requirements. Timber slat fences suit timber sleeper walls and offer a cohesive look. Colorbond panels on steel posts work well on concrete block or sleeper walls for low maintenance. Aluminium slat fencing provides a modern, durable option. Glass pool fencing is required where the wall retains a pool area.
