How to Price Garden Landscaping and Design: Soft Landscaping, Patios and Drainage

Quick Answer: A complete garden landscape project in the UK costs £80–£280/m² of garden area depending on hard:soft mix and finish quality. A small standard rear garden (40m²) typically £4,000–£12,000; medium (80m²) £8,000–£25,000; large designed garden (200m²+) £25,000–£100,000+. The breakdown is patio £80–£240/m² (Indian sandstone to porcelain), turf £8–£25/m² (rolled to instant), planting £30–£120/m² of bed (depending on plant size and density), fencing £80–£180/m run, and design fees 10–15% of build cost for a designer-led project.

Summary

Garden landscaping is one of the most variable trades to price because the same physical garden can be delivered for £4,000 or £40,000 depending on materials and finish. The customer's budget is set by aspiration (Pinterest, gardening magazines, friends' gardens), but the build cost is set by hard landscaping materials (paving, fencing, decking) which dominate the price. A coherent quote breaks the work into hard landscaping (typically 60–75% of cost), soft landscaping (15–25%), and structures/features (10–20%), and puts a realistic per-m² rate against each.

The pricing trap is the customer who wants "design" without paying for design. A landscape designer charges 10–15% of build cost for a fully detailed scheme — that's £2,500–£15,000 on the projects above — and the cost is justified because a designed garden uses materials more efficiently and avoids the £3,000–£8,000 in waste typical of unplanned builds. Builders who act as designer-by-default end up arguing about why the patio doesn't work or why the planting is wrong; getting the customer to a paid design stage avoids this.

The other under-quoted area is drainage. UK gardens with patios over 5m² draining onto adjacent land or to the highway are subject to SuDS rules, and clay or wet sites require land drainage anyway. Skimping on drainage produces patios that pond, lawns that rot, and beds that drown. Budget £10–£30/m² of garden area for drainage on most sites; up to £60/m² on very wet clay.

Detailed Guidance

The cost split — hard:soft:structures

A coherent landscape budget breaks roughly into:

The customer often wants the soft to be the highlight — "lots of planting" — but soft landscaping is cheaper to deliver than hard. A garden where the customer expects 50/50 hard:soft will probably get 70/30 once the patio and fencing are quoted properly. Manage this expectation early.

Patio — the price-defining choice

Patio material drives the front-loaded budget. Per-m² installed pricing:

Sub-base: 100mm Type 1 MOT, compacted in 50mm lifts. Bedding: 30–50mm 4:1 sharp sand and cement, or wet-mix concrete bed for porcelain. Joints: 3–8mm wide, brushed-in jointing compound (Geofix, Pavestone Easy Joint).

Don't quote patio installation without pricing the sub-base — it's typically £20–£35/m² of the £80–£240 total.

Lawn — turf vs seed

Most domestic clients want turf because of immediate result. Quote prep-work explicitly: topsoil to 100mm minimum (£25–£35/m² for soil + spreading), rotavate, level, fertiliser, then lay.

Planting — per-m² pricing

Plant density depends on plant size:

Plus topsoil amendment, mulch, irrigation if specified. Total planting cost typically £30–£120/m² of bed area. Mature gardens with specimens push higher.

Fencing — boundary cost

Posts at 1.8m centres, concrete-set in 600mm holes. Concrete posts (£40–£80 each) preferred for longevity over timber posts (£15–£30 each, 10–15 year life).

Drainage and soakaways

UK clay soils need drainage on most landscape projects. Three drainage systems commonly priced:

A typical 80m² garden on clay needs 1–2 soakaway points + 10–20m of drainage = £1,500–£3,500 in drainage budget.

Drainage and SuDS — front gardens

Front-garden hard surfaces over 5m² must comply with SuDS rules (Town and Country Planning [General Permitted Development] [England] Order 2015). Three legal options:

  1. Permeable surface (porous resin, gravel, permeable block paving)
  2. Surface drainage to soakaway within property (not to highway)
  3. Planning permission (£206 householder, 8 weeks)

Specify the option chosen at quote stage. Customers don't usually know this is a regulation.

Design — when to charge for it

A landscape designer should be paid for design work as a separate phase. Three approaches:

A builder who tries to "design as we go" without a separate paid design phase typically loses 5–15% on margin to design changes during build.

Frequently Asked Questions

How much is a complete garden makeover for a typical UK semi?

A 60–80m² rear garden, fully refreshed (new patio, lawn, beds, planted, plus fencing), typical 2026 budget £14,000–£28,000. Premium spec with porcelain patio, lighting, irrigation, mature planting £28,000–£55,000.

Can I get a designed garden for under £10,000?

Possibly for a very small garden (<30m²) with budget materials and minimal planting. £6,000–£10,000 is realistic. Larger or feature-led gardens won't come in under £15,000.

How much should I budget for planting alone?

10–25% of total build cost on most projects. £30–£120/m² of bed area depending on plant size and density. Typical small-to-medium garden: £1,200–£6,000 in planting.

Do I need planning permission for a patio?

Front gardens over 5m² in non-permeable material need planning. Rear gardens typically don't need planning unless the patio is over 30cm above adjacent land, near a boundary, or in a Conservation Area or AONB.

How long does a garden landscape project take?

Small (40m²): 2–3 weeks build time. Medium (80m²): 4–6 weeks. Large (200m²+): 8–16 weeks plus planting season constraints.
