Retaining Walls in Scarborough

Beachside Scarborough blocks sit on shifting coastal sand, and retaining walls here are as much about containing sand and managing drainage on redevelopment sites as holding a slope.

Retaining Wall Perth - Scarborough Guide

Scarborough's beachside blocks sit on shifting coastal sand, and retaining walls here are increasingly about redevelopment - containing sand and managing drainage on a site being rebuilt or extended - rather than holding back a hillside. As older beachside homes are redeveloped into larger contemporary builds, retaining is frequently part of that broader site works package, working with the same low-bearing sand conditions as neighbouring City Beach.

Why Scarborough homeowners use our help

Redevelopment-site experience

Scarborough's wave of beachside redevelopment means retaining work here is often coordinated as part of a larger site-works scope, not a standalone job.

Sand-containment focus

Coastal sand movement and drainage are the priority in every Scarborough design, ahead of a hills-style structural load.

Comfortable with redevelopment timelines

Retaining sequenced to fit a broader rebuild or extension program on a beachside block.

About Scarborough

Scarborough is one of Perth's best-known beachside suburbs, anchored by the Scarborough Beach foreshore and the Scarborough Beach Pool, with Abbett Park providing local green space back from the coast. The suburb has seen significant redevelopment in recent years, with older beachside homes increasingly replaced by larger contemporary builds on the same coastal sand-plain blocks.

Local conditions in Scarborough

The Esplanade and Manning Street sit within the same loose, low-bearing coastal sand system as City Beach, where retaining and site works go hand in hand on a redevelopment rather than being treated as a separate trade. West Coast Highway forms the suburb's eastern boundary on marginally more settled ground. Neighbouring Doubleview, Innaloo and Trigg share the same beachside sand conditions, and retaining approaches proven on a Scarborough redevelopment generally transfer directly across those suburb boundaries.

Scarborough - Frequently Asked Questions

How long does council approval take for a retaining wall in Perth?

Timeframes vary by council and by whether adjoining owner consent is required. Build in several weeks for a straightforward application, longer where a structural engineer's design or a boundary consent needs to be obtained first.

Does a retaining wall need to be engineered if it supports a pool?

Where a retaining wall forms part of a pool barrier or carries a surcharge from a pool structure, it is more likely to need building approval and an engineer's design regardless of height, because of the surcharge and safety-barrier requirements involved.

What is the difference between a limestone wall and a post and panel wall?

Limestone block walls are dry-stacked or mortared natural or reconstituted limestone blocks, a Perth-common look that suits the local geology. Post and panel (twin-side) walls use precast concrete panels slotted between posts - generally a faster install with a very consistent finish.

Can I build a retaining wall myself in WA?

A wall that retains no more than 0.5 metres, is not tied to other building work, and does not affect adjoining land or a boundary can be exempt from needing a building permit. Anything beyond that generally needs council approval and, depending on height and load, an engineer's design. Confirm your specific wall against your council's retaining wall information sheet first.
