Sandstone block and boulder retaining walls in Artarmon — the traditional Sydney material, built to last generations.
Fencing and Landscaping Experts provide sandstone retaining walls throughout Artarmon, NSW 2064, in Willoughby City Council's area on the Lower North Shore. The ground here is reactive clay that moves seasonally, so footings are sized for clay that swells and shrinks through the seasons, which is what pushes undersized posts out of plumb. For sandstone retaining walls in Artarmon, Sydney sandstone walls commonly stand for over a century. Per square metre of wall face, after a free site inspection. Licensed in NSW, insured to $20 million. Phone 0492 879 796.
Artarmon's industrial estate needs a very different fence to its residential streets — security mesh and palisade on one side of the railway, heritage-sympathetic timber and rendered piers on the other. That is the backdrop to every sandstone retaining walls job we do in Artarmon 2064, where the service uses sawn sandstone blocks or natural boulders, the material Sydney's original walls were built from and still the longest-lasting option available.
Sandstone walls are built, not assembled. Blocks are laid on a compacted base with a slight batter back into the slope, joints staggered, and the same drainage detail behind them as any engineered wall — the stone will outlast everyone involved, but only if water is not running through the wall. Sandstone is the historic Lower North Shore material, and on heritage properties and in conservation areas it is often the only wall material that will be accepted. Much of our work here is rebuilding failing original walls in kind. Artarmon's reactive clay swells when wet and shrinks when dry, and that seasonal movement is what pushes undersized footings out of plumb over a few years.
The ground under Artarmon is firm shale through the residential streets, with fill and made ground in the industrial pocket, and the suburb is built out with Federation and interwar homes on modest blocks, plus a substantial light-industrial estate. Those two facts decide footing depth, material choice and how long the job takes, so we measure on site before we price anything in Willoughby City Council's area.

We work across Artarmon and the surrounding Lower North Shore suburbs, and the local conditions genuinely change the job. Lower North Shore sites are tight, steep and often heritage listed. Access is usually the hardest part of the job: narrow frontages, shared driveways, harbour slopes and sandstone shelf under a shallow layer of soil.
For sandstone retaining walls specifically, the constraints that come up most often in Artarmon are narrow access, sandstone shelf, foreshore building lines and heritage conservation area controls. Willoughby City Council is the consent authority for Artarmon, so where approval is needed that is the path we work through with you — and we identify that before quoting rather than halfway through the job.
Sandstone is the premium retaining material, and in Artarmon the cost reflects the weight of the stone, the machinery needed to place it, and the skill of laying it well. Sawn block is more predictable in price than boulder work, which varies with the stone available. Against a 40-year service life it compares far better than the up-front figure suggests.
Longer than any other option. Sydney has sandstone walls still standing after 150 years. What fails is never the stone — it is the drainage behind it or the base beneath it, which is why we build Artarmon sandstone walls on a properly compacted base with a full aggregate drainage zone and subsoil drain.
Sawn block gives a formal, coursed wall face and is more predictable to price. Natural boulders produce an organic, landscape-led result that suits informal Artarmon gardens. We often use both on one property — block near the house, boulders further out.
It is usually the only material that is. On heritage items and in the conservation areas within Artarmon, Willoughby City Council will generally expect a sandstone wall to be repaired or rebuilt in kind rather than replaced with concrete. We work in matching stone and traditional coursing for exactly that reason.
In most cases yes. Sydney sandstone varies in colour and grain between quarries and weathers over time, so we select stone to sit alongside what is already on your Artarmon property and, where an old wall is being partly rebuilt, reuse the sound original blocks on the visible face.
All of Artarmon 2064, plus the surrounding streets in Chatswood, Lane Cove, Naremburn, St Leonards and Willoughby. Artarmon is characterised by Federation and interwar homes on modest blocks, plus a substantial light-industrial estate, and we schedule around what that means on the ground rather than booking a standard slot. We give you a firm start date with the quote rather than an open-ended window.
