Landscape Design
Landscape Design near you
Landscape design is the part of an outdoor project that happens on paper. Somebody measures the block, works out where the sun and the prevailing wind come from, resolves the levels, decides what is paved and what is planted, and produces drawings a builder can price and build from. On an Australian block that usually means reconciling three things at once: a slope, a stormwater problem, and a climate that punishes anything planted in the wrong aspect.

The confusion worth clearing up before you engage anyone is that in Australia the designing is largely unregulated while the building is not. Landscape architect is a credential: the Australian Institute of Landscape Architects awards Registered Landscape Architect through pathways that require an accredited qualification plus post-graduate experience. Landscape designer is not a protected term at all. Meanwhile the construction that follows is licensed trade work in most states once it passes a value threshold, and in New South Wales structural landscaping expressly covers retaining walls, paving, decks, pergolas and water features.
That split is where money is lost. A beautiful plan that cannot be built to the levels on the survey, or that assumes a retaining wall an unlicensed builder cannot legally construct, becomes a redesign at your expense. The useful test of a designer is not the rendering. It is whether the drawing set tells a licensed contractor what to build, to what levels, and where the water goes.
Landscape architect, landscape designer or design-and-construct: three different offers
All three will hand you a plan, but they carry different accountability and they suit different jobs. Work out which one you are buying before you compare fees, because the cheapest drawing is often the one that leaves the hardest decisions to the person holding the shovel.
- A Registered Landscape Architect holds a credential from the Australian Institute of Landscape Architects, awarded through pathways requiring an accredited degree plus years of practice.
- A landscape designer may be excellent and may be self-taught: the title carries no statutory meaning in Australia, so judge the portfolio and the documentation, not the word.
- A design-and-construct landscaper draws and builds, which removes the handover risk but also removes the independent eye on the construction.
- A horticulturist or plantsperson designs the planting only, and is often engaged alongside whoever resolves the levels and the hard surfaces.
- On a steep, filled or retained site a civil or structural engineer sits behind whoever designs, because the wall and the earthworks are their call, not the designer's.
What a landscape design package should actually contain
- A measured site survey with spot levels, not a sketch: everything downstream depends on knowing the existing ground.
- A concept plan you can argue with cheaply, before anything is documented in detail.
- A levels and grading plan showing finished surface levels, falls and any steps or retaining.
- A stormwater plan showing where surface water is collected and where it is taken.
- A hard landscape plan with materials, edges, jointing and setout dimensions.
- A planting plan with species, pot sizes and spacings, tied to the aspect and the soil actually on site.
- A specification and schedule the contractor prices line by line, so quotes from different builders are comparable.
Where a garden design meets the planning system
Plenty of landscaping never touches a council counter. New South Wales publishes an exempt development pathway under which many minor, low-impact works — decks, pergolas, garden sheds, fences, driveways, paths and paving, privacy screens, shade structures — need no planning or construction approval at all, provided every development standard in the relevant State Environmental Planning Policy is met and the work is structurally adequate.
The traps are the exclusions rather than the list. Exempt pathways are closed on heritage-listed property and in environmentally sensitive land, and every state runs its own version of the graded approval system, so the same pergola can be exempt in one jurisdiction and need an application in another. A designer earns their fee by telling you which pathway your drawing lands in before it is drawn, not after.
Site constraints that decide the design before you do
- Easements and sewer alignments, which limit what may be built over them and often decide where the paving stops.
- Registered trees and street trees, whose protection is set by your council and which constrain the footprint of everything nearby.
- Bushfire prone land, where what a structure may be built from is settled before its style is.
- Overland flow and low points, which decide where water will go in a storm whether the design acknowledges it or not.
- Soil reactivity, which governs how close paving and planting can sit to the house footings without causing seasonal movement.
- Boundary levels, because raising ground against a neighbour's fence is a retaining and drainage decision, not a landscaping one.
How landscape designs fail between the drawing and the build
- Levels that do not close: the plan assumes a fall the survey does not support, and the paving ends up above a door threshold.
- No stormwater strategy, so the builder improvises and the water ends up against the house or on the neighbour's side.
- Species chosen for a photograph rather than for the aspect, soil and water regime of the actual block.
- A retaining wall drawn but not engineered, which stalls the job while a design is commissioned mid-build.
- A specification vague enough that three quotes are for three different projects, which makes comparison meaningless.
- No staging plan on a large garden, so the whole thing must be funded at once or abandoned half-built.
Designing for the maintenance you will actually do
A garden is a commitment, and the honest conversation to have with a designer is about how many hours a month the household will really give it. Lawn area, clipped hedging, seasonal planting and water features all carry recurring labour; mass planting, mulched beds and durable paving carry much less.
Ask the designer to mark the maintenance load on the plan — which beds need regular attention and which are meant to close over and be left alone. Ask what the garden looks like in its second summer rather than on handover day, and what is expected to be replaced within a few years. A design that assumes a level of care nobody will provide is the most common way a good plan turns into a tired garden.
Landscape Design: frequently asked questions
Do I need a licensed contractor to build a landscape design in Australia?
For the structural parts, in most states yes, once the work passes the contract value threshold. New South Wales requires a contractor licence for residential building or trade work valued at more than five thousand dollars in labour and materials including GST, and its structural landscaping category expressly covers retaining walls that are not part of a habitable building, fencing, driveways, paths and paving, decks, pergolas and other non-habitable shelters, ornamental ponds and water features. Other states run their own licence classes and thresholds, so check the regulator's public register for your state before signing.
Is landscape architect a protected title?
The credential is. The Australian Institute of Landscape Architects awards Registered Landscape Architect through a mentorship pathway requiring an AILA accredited qualification plus at least two years of full-time post-graduate work, or a senior entry pathway requiring an accredited degree and at least eight years of experience. Landscape designer, garden designer and similar terms carry no equivalent requirement, which does not make those people less capable — it means the title tells you nothing and the documentation has to.
Should I get the design and the construction from the same company?
It depends on how much independent scrutiny you want during the build. A single firm removes the handover gap and is quicker, which suits straightforward gardens. Separating them gives you someone whose job is to check that what is being built matches what was drawn, which is worth more on a complex, retained or heavily documented site. If you do separate them, pay the designer for construction-stage review rather than leaving them out once the drawings are issued.
Will I need council approval for my landscaping?
Often not, but the answer is state and council specific. New South Wales runs an exempt development pathway under which many minor low-impact outdoor works need no approval provided every development standard is met and the work is structurally adequate and built in accordance with manufacturer specifications complying with the Building Code of Australia. Heritage items and environmentally sensitive land are excluded from that pathway. Have the designer confirm the pathway in writing at concept stage.
What is the single most useful drawing in the set?
The levels and grading plan. Almost every expensive landscaping failure is a levels failure in disguise: water sitting where it should not, a step that had to be invented on site, paving that finished too high against the house, a wall that grew taller than expected. A plan with real spot levels taken from a survey, and finished levels nominated across the whole garden, is what turns a picture into a buildable project.

What affects the cost of landscape design
Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:
- Size of the yard and the scope of the design
- Grading, excavation and drainage work
- Hardscape materials, such as stone, pavers or wood
- Plants, sod and soil
- Access for machinery
- Removal of old materials, trees or stumps
- How often visits are scheduled for ongoing services
How to compare landscape designers before you hire
- Choose a company that does the kind of work you need, since design, lawn care, tree work and hardscaping are different specialties.
- For big projects, ask for a site plan or drawing before work starts.
- Ask how they'll handle grading and drainage so water moves away from the house.
- For tree removal or large pruning, look for a qualified arborist with liability insurance.
- For ongoing services like lawn care or snow removal, get the visit schedule and what's included in writing.
Questions to ask landscape designers before you hire
- Can I see a plan or drawing before you start?
- How will you handle drainage and grading?
- Will you have underground utilities located before you dig?
- Does any of this work need a permit, such as for a retaining wall, fence or tree removal?
- What plants or materials do you recommend for our climate and my yard's sun and shade?
- Do you guarantee plants or sod, and for what conditions?
- Can you show me proof of liability insurance?
When to call a pro for landscape design
- Water that pools near the house or in the yard after rain
- A tree that is leaning, cracked or has large dead branches over the house or a driveway
- A retaining wall that is bulging, leaning or cracking
Landscape design permits and local rules
Some landscape design work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
