There is no standard price for landscape design in Perth, and any figure quoted without seeing your block is a guess. Landscaping costs vary greatly depending on the size of your outdoor space, what the design has to resolve, and how much of the finished yard is hard landscaping rather than planting.
What can be answered honestly is what moves the number. Two backyards of identical size on the same street can differ substantially in price because one is flat with a wide side gate and the other slopes away behind a narrow one.
What You Are Paying For at Each Design Level
Landscape design is priced by depth of documentation, not by hours on site. The more a plan has to resolve before a shovel moves, the more it costs.
Most Perth homeowners work with landscape designers rather than a landscape architect. An architect is generally engaged on large commercial or public landscaping work, while residential garden design sits with a designer who knows local soils, plants and councils.
| Design Service Level | What It Includes | When It Is Worth It |
| Initial Consultation | On-site visit to discuss ideas, spatial layout and preliminary plant choices | You want direction before committing to anything |
| Basic Concept Plan | Overhead 3D layout | Straightforward block, staged build, clear brief |
| Detailed Design Package | Scaled 3D concept, basic material definitions, zones for lawn and garden beds | You want the build priced accurately and without variations |
| Full Documentation | Engineering plans, 2D structural plans, formal documentation for council approval | Sloping sites, retaining over height, anything needing approval |
What separates those tiers is risk removed. A concept plan tells you what the space could be. A detailed package tells the builder exactly what to build, which stops variations appearing mid-job.
Actual costs depend on design complexity far more than block size. A flat rectangular yard with three simple zones documents quickly and costs less to design. A sloping site carrying retaining walls, drainage and multiple levels takes more work and costs accordingly.
Most Perth homeowners do not need the top tier. It earns its cost on sloping blocks and on anything requiring council approval.
Which Services Push a Landscaping Quote Up
The biggest driver of what you pay is which services the design calls for.
How much landscaping costs once the drawings are done depends almost entirely on this list.
| If the design includes | Effect on cost |
| Retaining walls | Significant increase, and more again where height triggers engineering and council approval |
| A pool and its surrounds | The largest single increase of any feature |
| An outdoor kitchen or outdoor entertaining zone | Significant increase, driven by services, benchtops and structure |
| Decking | Moderate to significant increase. Decking cost varies with the board, and composite carries a higher upfront cost than timber |
| Custom paving | Moderate to significant increase. Paving cost depends heavily on the material chosen |
| Reticulation | Moderate increase, and effectively unavoidable in Perth |
| Turf or artificial turf | Moderate increase. Artificial turf costs more upfront and less to maintain |
| Garden lighting | Modest increase for a noticeable gain in usable hours |
| Water features | Modest to moderate increase, depending on scale and plumbing |
| Garden beds and planting | The smallest increase per square metre of any element |
| A refresh only, meaning lawn replacement and fresh mulch | The lowest-cost option of all, and the fastest to deliver |
The pattern is obvious. Hardscaping features increase costs faster than anything you plant beside them, because paving, retaining, decking and structures carry material and labour weight that garden beds never do. Larger projects vary based on the various features packed into the space rather than square metres alone.
Reworking a plan to shift the balance between hard and soft is the most effective way to bring a quote down without cheapening the result.
Trimming the paved area and extending the garden beds changes the number more than swapping one paver for another ever will.
What Else Drives the Cost of a Landscaping Project
Access and Slope
A narrow side gate and no rear laneway access means every load of material is barrowed in by hand, which adds labour to every stage. If a bobcat can get in, the same job costs less.
Sloping blocks bring retaining, levels and drainage that a flat block never needs, so a sloping site always costs more than an equivalent flat one.
Both are set by the site rather than the design, and worth knowing before you fix a landscaping budget.
Materials and Where They Come From
Western Australian limestone and native timbers avoid the transport premium on interstate stone, and premium natural stone pavers cost several times what basic concrete pavers cost for the same area.
Material costs are the biggest lever you control after the size of the paved area, and choosing local can reduce the structural budget without changing the design at all.
Where Perth Homeowners Waste Money
The expensive mistakes are rarely about buying cheap materials. They are about sequence.
Starting with features instead of a plan is the costliest. It is far cheaper to move a line on a drawing than to rebuild a finished feature, which is the argument for planning the transformation properly first.
Building piecemeal costs more than one staged plan and rarely reads as one considered space. Cutting soil preparation and reticulation to afford more paving is a false saving, paid back by replacing dead plants every summer.
Taking the cheapest quote without checking what has been left out is another, and so is treating design as the line item to cut when it protects every other one.
Bringing a professional into a complex landscaping job avoids the costly mistakes that cost more to undo than they ever saved.
You save money on sequence, not on quality.
Perth Conditions That Change the Cost
Sandy soil cuts both ways. Perth sand is quick and cheap to excavate compared with the clay of the eastern states, which lowers earth-moving costs. It holds almost no water or nutrients, though, so heavy soil conditioning is not optional here.
Reticulation is effectively mandatory. Automated reticulation is what keeps a garden alive under our water restrictions, so it is a line item rather than an upgrade. Irrigation systems are standard in functional garden design in the Perth climate, and a new lawn rarely survives its first summer without one.
Plant selection changes the ongoing cost more than the upfront one. Drought-tolerant native plants such as kangaroo paw, grevillea and banksia cost much the same to plant as thirsty exotics and far less to keep alive.
Choose low-maintenance plants matched to local conditions and the ongoing maintenance bill drops with them, leaving you an outdoor area you use rather than a standing weekend job.
A garden planted for our climate holds its shape for years, which is worth building into maintenance costs from the start.

Every price range on this page is a starting point, not a quote. What your project actually costs comes down to your block, its access and slope, and how much hard landscaping the design carries.
The only way to get a number worth budgeting against is to have someone walk the site and price the work properly.
We handle design and construction under the one team, so the plan gets costed by the people building it, and the quote and the drawings describe the same project.
