A garden designer is a creative professional who translates a client's vision into a coherent outdoor space - combining practical knowledge of plants, soils, hard materials and drainage with an eye for layout, proportion and planting composition. Garden designer is not a regulated title in the UK, but membership of the Society of Garden Designers (SGD) is the recognised quality indicator, requiring members to demonstrate professional experience and adhere to a code of conduct.
What they do
- Carry out measured surveys of the existing garden
- Produce concept masterplans and design options
- Prepare detailed design drawings and sections
- Produce planting plans and plant schedules
- Write specifications for hard and soft landscape works
- Obtain quotes from hard landscapers and soft landscapers
- Supervise construction works on behalf of the client
- Advise on maintenance requirements after completion
When you need one
A garden designer is most valuable when you want a cohesive design that brings together hard and soft landscaping, or when you need detailed drawings and a specification for a contractor to work from.
Typical costs (UK, 2025)
| Job type | Typical cost |
|---|---|
| Initial consultation | £200 - £400 |
| Concept and masterplan | £500 - £2,000 |

Costs increase with garden size, complexity and the level of project management required. A London-based SGD member at the top of their profession may charge significantly more than the upper end of these ranges.
Qualifications to look for
SGD membership is the principal quality indicator for garden designers in the UK. Members must demonstrate professional experience and design ability, and adhere to a code of conduct. The SGD has a Find a Garden Designer directory at sgd.org.uk.
Many garden designers hold an RHS qualification in horticulture or a dedicated diploma in garden design from a horticultural college. These demonstrate structured horticultural and design training, though they are not mandatory for practice.
How to find a reputable garden designer
Frequently asked questions
What does a garden designer actually produce?
A garden designer typically produces a measured survey, concept masterplan, detailed design drawings, planting plan, plant schedule and specification - enough information for a hard landscaper and soft landscaper to price and build the garden.
Do I need a garden designer or a landscape architect?
For private residential gardens a garden designer is usually sufficient. For planning applications, large developments or sites in sensitive landscapes a chartered landscape architect (CMLI) is typically required by the local planning authority.
How long does garden design take?
A full design for a medium-sized garden typically takes 4-8 weeks from commission to final drawings. Build time depends on the scope of hard landscaping - a major project with stonework, drainage and a new lawn may take 4-8 weeks to construct once design is complete.
