Dividing and boundary fencing in Castlecrag built on the surveyed line — Colorbond, timber and aluminium, with neighbour cost-sharing handled properly.
Fencing and Landscaping Experts provide boundary fencing throughout Castlecrag, NSW 2068, in Willoughby City Council's area on the Lower North Shore. 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. For boundary fencing in Castlecrag, the standard is a 1.8m dividing fence. Per lineal metre supplied and installed, after a free on-site measure. Licensed in NSW, insured to $20 million.

We work on boundary fencing throughout Castlecrag 2068. The service is the dividing fence between you and your neighbour, which makes it as much a legal question as a construction one, and in this suburb one thing shapes it more than anything else. Castlecrag's Walter Burley Griffin heritage character actively discourages high solid front fencing, and natural sandstone is the material that belongs here.
A boundary fence has to sit on the actual boundary, not where the last fence happened to be. Where the line is unclear or the existing fence has crept, we say so before quoting rather than building in someone else's mistake. On tight Lower North Shore blocks a few centimetres of encroachment is a real dispute, so on narrow-frontage sites we recommend confirming the line against a survey before anything is built. Access is a genuine cost factor in Castlecrag — where materials have to be carried down a stepped side path or worked off a slope rather than delivered straight to the work, the labour component rises.
Castlecrag sits in Willoughby City Council's area, and the ground here is dramatic sandstone outcrops with very shallow soil and natural rock shelves through most gardens. With Griffin-era and mid-century homes designed to sit into the landscape rather than dominate it, that shapes what works and what does not — which is why every Castlecrag quote follows a free on-site measure rather than a price off a screen.

A low retaining wall and fence built as one structure where levels differ across the line.
Documentation set out so it can be served on an adjoining owner under the Act.
The default 1.8m dividing fence — low maintenance, private, and available in the full Colorbond range.
Treated pine or hardwood palings, lapped or capped, in a traditional Sydney style.
Powder-coated aluminium where corrosion resistance or a lighter look matters.
Panels stepped down a fall so the fence follows the ground without gaps underneath.
We work across Castlecrag 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 boundary fencing specifically, the constraints that come up most often in Castlecrag are narrow access, sandstone shelf, foreshore building lines and heritage conservation area controls. Willoughby City Council is the consent authority for Castlecrag, 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.
Under the NSW Dividing Fences Act 1991, owners on both sides of a boundary in Castlecrag normally contribute equally to a sufficient dividing fence. In practice that means a standard 1.8m Colorbond or timber paling fence. If one owner wants more than that, they generally fund the difference. We set our quotes out so they work as the basis of a Fencing Notice.
1.8 metres is the accepted standard for a side and rear dividing fence in Castlecrag and across Willoughby City Council's area, and it is what most exempt development provisions are written around. Front boundaries are treated differently and are usually limited to a much lower height, particularly on a corner block or in a conservation area.
You can serve a Fencing Notice under the Act, which sets out the proposed work and the cost split and gives the adjoining owner 30 days to respond. If there is still no agreement the matter can go to the NSW Civil and Administrative Tribunal. We give you a clear written Castlecrag quote to attach, which resolves most disputes without going that far.
Castlecrag blocks fall enough that a level fence line is rarely the right answer. We step the panels down the fall in short runs, or rake the panels to follow the ground where the style allows. Where the level change across the boundary is large, a low retaining wall with the fence built above it is usually the better solution.
We will not knowingly rebuild an encroachment. If the existing Castlecrag fence looks like it sits off the true boundary, we flag it and recommend confirming the line with a registered surveyor first. It is a small cost next to rebuilding a fence twice or arguing about it later.
All of Castlecrag 2068, plus the surrounding streets in Northbridge, Willoughby, Middle Cove and Roseville. Castlecrag is characterised by Griffin-era and mid-century homes designed to sit into the landscape rather than dominate it, 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.
