Landscape Design Process: Explained Step by Step

Ask three landscapers to describe the design process and you will get three different answers, with different numbers of steps and different names for each. That is not evasiveness. It reflects a genuinely standard method that different people carve up differently. This guide sets out what the stages are, what document you should receive at the end of each one, and what the elements and principles behind the drawings actually mean. The framework follows the widely cited University of Florida design process, adapted for Australian conditions.

Quick answer:  The landscape design process has five core stages: site inventory and analysis, determining your needs, functional diagrams, concept design, and the master plan with documentation. The first three work out what the site allows and what you need. The last two turn that into a plan a builder can price and construct. Underpinning all of it are five design elements (line, form, texture, colour, scale) and seven principles (unity, balance, proportion, transition, rhythm, focalisation, simplicity).

First, what landscape design actually is

Landscape design is the process of organising the natural and built features of an outdoor space into something that works aesthetically, functionally and environmentally. The emphasis on all three matters. A garden that photographs well but floods, or one that drains beautifully and looks like a car park, has failed at the job.

The titles used in the industry cause confusion, so it is worth separating them. A landscape architect holds a university degree and is registered with the Australian Institute of Landscape Architects. Landscape designer is not a protected title in Australia. A landscaper or landscape contractor builds the design and holds the licences required for structural work.

For most residential gardens, a capable designer working alongside a licensed contractor is the right combination. Large, complex or public sites, and anything needing structural certification, are where an architect earns their fee.

Stage 1: Site inventory and analysis

The process starts with the site rather than with ideas, and there is a reason for that order. Every subsequent decision is constrained by what the ground gives you.

A site inventory records soil type, topography and drainage, climate and microclimates, existing vegetation, and the location of services, boundaries and structures on an accurate base map. Soil determines what will grow: amending soil is expensive and often ineffective, so the sensible approach is choosing plants suited to what you already have. Existing vegetation gives clues, since areas where plants struggle are telling you something.

The Australian correction:  Overseas guides describe south-facing gardens as the sunny ones. In the southern hemisphere north is the sunny aspect. Sun and shade patterns also shift with the seasons and as trees mature, so a yard should be observed at different times of day before anything is fixed.

Drainage problems are identified and corrected at this stage, not later. A good design moves water away from the house and reroutes it elsewhere in the yard. On the reactive clay across much of Sydney this single decision shapes much of the budget.

Stage 2: Determining your needs

The second stage covers the people. There are five questions worth answering honestly: how do you use the yard now, how do you want to use it, how do you want it to look, are you a hands-on or hands-off maintainer, and what is the budget.

The first question gets skipped most often and matters most. Which entry does everyone actually use? Where do the kids play? Where does the dog run? Existing habits are stubborn, and a design that fights them loses. Being realistic about maintenance style is equally important, since an ambitious planting plan handed to someone with no time becomes an overgrown disappointment. If you are still working out what appeals, our backyard landscaping ideas guide is a useful reference.

Stage 3: Functional diagrams

With the site and the brief established, the designer locates activity areas on the plan. This is the bubble diagram stage: rough shapes for dining, lawn, planting, service areas and the circulation between them.

The organising idea here is the outdoor room. Spaces are separated and defined by plant beds, level changes, walls, arbors and paved surfaces so that each feels enclosed rather than exposed. People are more comfortable in spaces that feel sheltered, and the wall of the house usually forms the first wall of the first room. Incompatible uses get separated, related uses like cooking and dining get grouped.

Diagrams are quick to redraw, which is the point of them. Mistakes made here cost nothing.

Stage 4: Concept design

The concept turns the diagram into a proposal. It settles the form theme, the shapes of spaces, the general material palette and the character of the garden, usually presented as a plan with reference imagery rather than construction detail.

Form themes are typically geometric, following the shape of the house, or naturalistic with curved, organic edges. Many gardens combine them, using geometric hardscape with curved planting beds. Style themes usually take their cue from the architecture, which is what creates a sense of the garden belonging to the house rather than being applied to it.

A concept exists to be argued with. Changes at this point cost a conversation; the same change during construction costs money.

Stage 5: The master plan and documentation

The final stage produces the buildable document: a scaled and dimensioned plan with all the hardscape and planting detail required for installation, materials named, levels set, and a planting schedule listing species, sizes and quantities. Irrigation and lighting layouts are usually included.

This is also the point where approvals get resolved. Retaining walls above set heights, pools, larger decks and pergolas generally need approval in NSW, while planting, turf and low paving usually fall under exempt development. Sorting this while the design can still flex is far cheaper than redesigning around it.

What you should receive at each stage

If you are engaging a designer, this is a reasonable expectation of deliverables. Ask upfront which of these are included, because scopes vary widely.

The five elements of landscape design

Elements are the raw materials a designer composes with. They are worth understanding because they explain why a garden feels right or wrong when you cannot articulate the reason.

• Line. Bed edges, paths and structures direct the eye and control how people move. Straight lines read formal, curves read relaxed.
• Form. The shape of plants and structures. Form is the most enduring characteristic, since it persists long after flowering ends.
• Texture. Coarse through to fine. Coarse textures make a space feel smaller, fine textures make it feel larger.
• Colour. The most noticeable element seasonally, though form and texture carry the garden for most of the year. Warm colours advance, cool colours recede.
• Scale. How everything relates in size to the house, the block and the people in it. Undersized planting against a large facade is a common failing.

The seven principles of landscape design

Principles are how the elements get organised. These are the terms designers use when explaining why something is not working.

Unity means the garden reads as one space, usually achieved through repetition of a limited plant and material palette. Balance distributes visual weight, either symmetrically or informally. Proportion sizes elements to the house and block. Transition avoids abrupt jumps in height, texture or material. Rhythm uses repetition to carry the eye through the space. Focalisation gives the eye a destination. Simplicity is restraint, and in practice it is the principle most often abandoned, usually at the nursery.

So is it five steps, seven, or nine?

This question comes up constantly, and the honest answer is that the number is arbitrary. The University of Florida framework uses five stages. Seven step versions usually split the initial consultation out from site analysis and add construction and handover at the end. Nine step versions subdivide further, often separating planting design and lighting into their own stages.

The underlying method does not change: understand the site, understand the user, diagram the function, develop a concept, document it properly, build it, then look after it. If a designer describes their process using different numbers to another, that tells you nothing about their competence. What matters is whether all of the substance is covered and what you receive at each point.

What design costs and how designers charge

A design consultation typically starts around $300 to $1,500 depending on site size and how much advice you want. Full concept and documentation packages are usually quoted either as a fixed fee or as a percentage of the expected construction budget, commonly in the range of 8 to 15 per cent. Some designers credit the consultation fee against a full engagement, so it is worth asking. For what the construction itself tends to cost, see our Sydney landscaping cost guide.

Treat design as part of the build budget rather than an optional extra. The changes a documented plan prevents almost always cost more than the drawings did.

Why designs fail

• Skipping site analysis. Soil, levels and drainage constrain everything. Designing before knowing them means redesigning later.
• Designing for a photo. Magazine gardens are outstanding examples chosen for that reason. Adapt ideas to your site, budget and interest level.
• Ignoring mature size. Plants spaced to look full on day one become an overcrowded maintenance problem within a few years.
• No form theme. Without a governing shape logic, spaces end up as leftover gaps between features.
• Too many ideas. Simplicity is a principle, not a compromise. Collections read as clutter.
• Stopping at the concept. A concept cannot be priced accurately. Builders will either pad the quote or find variations later.

Working with a designer

A good process should feel like a series of decisions rather than a reveal at the end. You should see the site analysis, agree the brief in writing, react to a diagram before a concept, and receive documentation you could hand to any builder.

Frequently asked questions

1. What is the landscape design process?

The landscape design process is a structured method for turning an outdoor space into a functional garden. It runs through five stages: a site inventory and analysis, determining the user’s needs, creating functional diagrams, developing a concept design, and drawing a final master plan. The first three stages establish what the site allows and what you need from it. The last two apply those findings to produce a plan that can be priced and built.

2. What are the 7 steps in the design process?

Different sources count the stages differently, which is why you will see five, seven and nine step versions of the same thing. The University of Florida’s widely cited framework uses five: site inventory and analysis, determining needs, functional diagrams, conceptual design, and the final plan. Seven step versions usually split out the initial consultation and add construction or handover at the end. The substance is identical; only the labelling changes.

3. What are the 5 basic elements of landscape design?

The five elements are line, form, texture, colour and scale. Line directs the eye and controls how people move through a space. Form is the shape of plants and structures, and is the most enduring quality because it lasts beyond any flowering season. Texture ranges from coarse to fine and changes how large a space feels. Colour provides seasonal interest. Scale governs how everything relates to the house and to the people using it.

4. What are the 7 principles of landscape design?

They are unity, balance, proportion, transition, rhythm, focalisation and simplicity. Unity means the garden reads as a single space rather than a collection of ideas. Balance distributes visual weight. Proportion sizes everything to the house and block. Transition avoids abrupt changes in height or material. Rhythm uses repetition to carry the eye. Focalisation gives the eye somewhere to land. Simplicity is restraint, and it is the principle most often ignored.

5. What is the difference between a landscape designer and a landscape architect?

A landscape architect holds a university degree, is registered with the Australian Institute of Landscape Architects, and typically works on complex, public or large-scale sites, including work requiring structural certification. Landscape designer is not a protected title in Australia, and designers generally focus on residential gardens, concept plans and planting design. For most home projects a good designer is the appropriate choice; large or technically complex sites may warrant an architect.

6. What is the difference between a concept plan and a master plan?

A concept plan communicates layout and intent. It is deliberately loose, usually paired with reference images, and exists to be argued with before anything is committed. A master plan is the buildable document: scaled and dimensioned, with materials named, levels set, and a planting schedule listing species and quantities. Only a master plan lets several builders quote the same scope, which is the only way to compare prices fairly.

7. How much does landscape design cost in Australia?

A design consultation typically starts around $300 to $1,500 depending on the size of the site and the depth of advice. A full concept and documentation package for a residential garden costs considerably more, and is usually quoted either as a fixed fee or as a percentage of the expected construction budget, commonly around 8 to 15 per cent. Treat design as part of the build cost, since it prevents changes that cost far more during construction.

8. Do I need a landscape design before building?

You can build without one, and it is the most common reason projects run over budget. Without documentation, decisions get made on site under time pressure, materials are ordered piecemeal, and level or drainage problems surface after surfaces are laid. A documented design also lets multiple builders quote identical scope. For small planting projects a design may be unnecessary, but for anything involving levels, drainage or structures it pays for itself.
