Sandstone block and boulder retaining walls in Terrey Hills — the traditional Sydney material, built to last generations.
Fencing and Landscaping Experts provide sandstone retaining walls throughout Terrey Hills, NSW 2084, in Northern Beaches Council's area on the Forest District. The ground here is sandstone shelf close to the surface, so posts are frequently drilled and chemically anchored into sandstone rather than concreted into a dug hole. Bushfire prone land applies to much of the suburb, so material within the asset protection zone has to be non-combustible. For sandstone retaining walls in Terrey Hills, 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.
We work on sandstone retaining walls throughout Terrey Hills 2084. 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, and in this suburb one thing shapes it more than anything else. Terrey Hills acreage means long rural-style boundary runs, horse and stock fencing and gated driveway entries — a different scale of job to standard suburban work.
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 non-combustible and locally native to the Forest District's geology, making it both the compliant and the visually appropriate choice against bushland boundaries. Sandstone sits close to the surface across much of Terrey Hills, so posts are often drilled into rock and chemically anchored rather than concreted into a dug hole.
Terrey Hills sits in Northern Beaches Council's area, and the ground here is sandstone plateau with very shallow sandy soil over near-continuous rock. With acreage and semi-rural holdings alongside standard residential blocks, that shapes what works and what does not — which is why every Terrey Hills quote follows a free on-site measure rather than a price off a screen.

We work across Terrey Hills and the surrounding Forest District suburbs, and the local conditions genuinely change the job. The Forest District sits against Garigal and Ku-ring-gai Chase National Parks. Most of it is bushfire prone land, which directly restricts what a boundary fence can be built from within the first few metres of a home.
For sandstone retaining walls specifically, the constraints that come up most often in Terrey Hills are bushfire prone land and BAL ratings, large bushland-interface blocks and sandstone rock. Northern Beaches Council is the consent authority for Terrey Hills, 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 Terrey Hills 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 Terrey Hills sandstone walls on a properly compacted base with a full aggregate drainage zone and subsoil drain.
Boulder walls sit beautifully in Terrey Hills's natural landscape and work with the existing rock rather than against it. Sawn block gives a crisper, more formal line where the wall is close to the house or forms part of an entertaining area.
It is usually the only material that is. On heritage items and in the conservation areas within Terrey Hills, Northern Beaches 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 Terrey Hills property and, where an old wall is being partly rebuilt, reuse the sound original blocks on the visible face.
All of Terrey Hills 2084, plus the surrounding streets in Belrose, Duffys Forest, St Ives Chase and Ingleside. Terrey Hills is characterised by acreage and semi-rural holdings alongside standard residential blocks, 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.
