Turning steep and uneven backyards in Warrawee into usable flat space — retaining, terracing, drainage, steps and turf.
Fencing and Landscaping Experts provide sloping backyard landscaping throughout Warrawee, NSW 2074, in Ku-ring-gai Council's area on the Upper 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 sloping backyard landscaping in Warrawee, we set the levels first, then retain and drain them. Per project, after a levels and access assessment. Licensed in NSW, insured to $20 million.

Warrawee's long boundary runs mean fence lines here are measured in tens of metres, so getting post spacing and rail sizing right is what stops a fence bowing five years in. That is the backdrop to every sloping backyard landscaping job we do in Warrawee 2074, where the service turns a backyard you cannot use into flat, level space — through retaining, terracing, cut and fill, drainage and access steps.
A sloping yard is solved by deciding where the flat parts go before anything is built. We set the levels first, then work out what retaining is needed to hold them and where the water will go, rather than building walls and hoping the levels work out. Upper North Shore slopes usually fall toward a bushland gully, which means the design has to move water away safely without simply dumping it on the neighbour or into the reserve. Warrawee'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 Warrawee is shale-capped ridge soils that hold water through winter, over sandstone at depth, and the suburb is built out with very large lots with long side boundaries, high hedges and significant mature plantings. Those two facts decide footing depth, material choice and how long the job takes, so we measure on site before we price anything in Ku-ring-gai Council's area.

We work across Warrawee and the surrounding Upper North Shore suburbs, and the local conditions genuinely change the job. The Upper North Shore is Sydney's leafiest fencing environment. Large blocks, mature canopy and Ku-ring-gai and Hornsby's tree-protection controls mean post holes frequently land inside a tree protection zone, and heritage conservation areas set the tone for what a front fence is allowed to look like.
For sloping backyard landscaping specifically, the constraints that come up most often in Warrawee are tree protection zones, heritage conservation area controls and sloping sandstone-over-shale blocks. Ku-ring-gai Council is the consent authority for Warrawee, 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.
Almost always. The question is how much flat area you need and what it costs to hold it. Many Warrawee yards need only a single low wall and some careful cut and fill to produce a genuinely usable flat area. We look at the fall, the soil, the access and the drainage, then show you what is achievable at a few different budget levels.
Cost is driven by the volume of earth moved and the retaining needed to hold the new levels. In Warrawee the two biggest variables are what is under the surface — heavy clay in Warrawee excavates readily but holds water, which changes the drainage design — and whether machinery can reach the work. We assess both before quoting.
Usually, yes. Two or three lower walls are cheaper to build than one tall engineered structure, are less likely to require certification, and generally produce a more usable and better-looking garden. On steep Warrawee blocks terracing is nearly always the better answer.
Excavation and fill beyond modest limits, and retaining walls over the 600mm exempt threshold, will generally need approval from Ku-ring-gai Council. Work near a boundary, on a steep site, or affecting drainage attracts more scrutiny. We identify the approval path as part of quoting rather than leaving it to you.
Deliberately, and early. Water is what destroys slope landscaping — it scours new turf, saturates fill and pushes over retaining walls. On Warrawee slopes we install subsoil drainage behind every wall and manage surface water with falls, spoon drains and pits so it leaves the site the way it is supposed to.
All of Warrawee 2074, plus the surrounding streets in Wahroonga, Turramurra and Pymble. Warrawee is characterised by very large lots with long side boundaries, high hedges and significant mature plantings, 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.
