Retaining Walls
Retaining Wall Builders — North Shore & Sydney
North Shore Landscaping Pty Ltd designs and builds retaining walls across Sydney's North Shore. Sandstone, stone, timber sleeper and concrete retaining wall construction, installation and repair — engineered, drained correctly and finished to last. Over 35 years working the steep blocks and sandstone soils of the North Shore.
Retaining Wall Construction Across the North Shore
Most North Shore blocks slope. A well-built retaining wall turns an unusable fall into flat, usable garden — a level lawn, a terraced garden bed, a driveway cut or a pool surround. As retaining wall contractors working locally since 1989, we handle the whole job: excavation, engineering, footings, drainage, construction and the landscaping that finishes it.
Sandstone Retaining Walls
Sandstone is the signature North Shore material. We build both dry-stone and mortared sandstone walls using sawn blocks or rough bush rock, matching the stone to your home and existing garden. Sandstone walls suit heritage properties in Killara, Wahroonga and Gordon and age beautifully over decades.
Concrete & Timber Sleeper Retaining Walls
Concrete sleeper walls give you clean, straight lines with galvanised steel posts and a long service life — ideal for driveway edges, pool terraces and boundary level changes. Timber sleeper walls are a cost-effective, natural option for garden beds and informal terracing. Both are installed with engineered posts, compacted backfill and full drainage.
Stone & Rendered Block Walls
For contemporary homes we build core-filled block walls, either rendered and painted or clad in stone. These walls handle serious retained height, integrate with paving and steps, and can carry lighting, planters and seating as part of the design.
Engineering, Drainage & Council Requirements
Walls that fail almost always fail for the same reasons: no drainage, poor footings or no engineering. We build to engineered detail where required, install ag-line drainage and outlets behind every wall, and arrange certification and council documentation when the wall height or location calls for it.

Frequently Asked Questions
How much does a retaining wall cost on the North Shore?
Cost depends on wall height, materials and site access. Timber and concrete sleeper walls are the most economical, while sandstone and dry-stone walls sit at the premium end. We quote each site after a visit so the price reflects the real ground conditions, drainage and access on your property.
Do I need council approval for a retaining wall?
In most North Shore council areas, low walls within set height limits can be built as exempt development, while taller walls, walls near boundaries or walls supporting a structure need approval and engineering. We advise on what your wall requires and arrange engineering certification when it is needed.
Which retaining wall material should I choose?
Sandstone suits heritage and garden settings across Killara, Pymble and Wahroonga. Concrete sleepers are strong, straight and cost-effective for level changes. Timber sleepers suit informal gardens. Stone and rendered block walls suit contemporary homes. We match the material to the slope, the load and the look of your garden.
How long does a retaining wall take to build?
A straightforward garden wall is typically built in a few days. Larger engineered walls with excavation, drainage and agricultural pipe can run one to three weeks depending on height, length and site access.
Do you handle drainage behind the wall?
Yes. Every wall we build includes correct backfill, ag-line drainage and outlets. Poor drainage is the single most common cause of retaining wall failure, so it is never treated as an optional extra.
