Garden Design Cost Guide Hampshire 2026

Three decades of honest Hampshire prices — the real cost of garden design and landscaping in 2026, with no marketing fluff.

“How much does garden design cost?” is the question we hear most often on Hampshire doorsteps. There’s no single answer, but there is an honest one. After 30 years and 500+ Hampshire projects, here’s our family team’s plain-English guide to what garden design and construction really cost across the county in 2026.

Quick price summary

What affects the cost of garden design in Hampshire?

Six main factors:

• Garden size — the obvious one. A 60m² back garden behind a Fareham terrace costs very differently to a half-acre Petersfield plot.
• Level changes — sloping Hampshire gardens (common around Romsey, Petersfield and the South Downs) need retaining walls, steps and proper drainage. Adds 25-50% to construction cost vs flat plots.
• Material choices — Indian sandstone is the most popular Hampshire patio material at around £60-90/m² supplied; porcelain costs £90-140/m²; granite is £110-180/m².
• Access — can a wheelbarrow get from the road to the back garden, or does everything have to come through the house? Tight terraced-house access (common in central Southampton, parts of Winchester) adds labour cost.
• Existing garden state — clearing an overgrown garden adds 1-2 weeks of labour plus disposal costs.
• Lighting and water features — an outdoor electrical circuit done properly is £800-£2,000 depending on complexity.

The design stage: what does £1,200 – £8,000 actually buy you?

Outline design (£600 – £1,200)

A 2D plan showing the structural layout of your new garden — patios, paths, lawn, key planted areas. Suitable if you have a clear idea of what you want and just need someone to draw it up properly. Often what people choose when they’re building it themselves or with a non-design landscaper.

Full bespoke design (£2,500 – £8,000)

The full Helyers package: detailed 2D plans, a 3D model you can walk through on screen, a complete planting plan with specific varieties and quantities, materials list with sourcing notes, lighting scheme, and itemised construction cost estimate. This is what you want if you’re investing properly in your garden — you’ll save the design fee many times over in avoided mistakes.

Why our family team gives free design consultations first

We don’t believe in charging customers to find out whether we’re right for them. The first visit is always free and we’ll give you an honest opinion, even if that opinion is “you don’t need a designer for this, just hire a good landscaper.” Roughly one in eight of our consultations end with us recommending the customer not to pay for design at all — it costs us a morning but it’s the right thing to do.
