Last reviewed: · How we research

Landscaping is one of the last big line items in a Adelaide build - and one of the least regulated. Prices vary 2x for the same scope, quality gap between the top 8-10 Adelaide operators and the rest is huge, and the biggest Adelaide risk (drainage) rarely appears in a quote. This guide walks through the real all-in ranges for soft-scape and hard-scape, the PlanSA approvals you actually need, and how to compare Adelaide landscaping quotes on a shared inclusions sheet.

Soft-scape vs hard-scape, real Adelaide pricing

Adelaide landscapers price in three buckets: soft-scape (lawn, garden beds, planting, irrigation), hard-scape (paving, walls, decks, driveways, drainage) and structures (pergolas, screens, water features). Soft-scape is where the margins are lowest and the quality difference is smallest. Hard-scape is where the money and the risk sit, this is where you need engineered detailing, particularly for retaining walls over 900mm.

  • Turf-only refresh (small yard), $6,000-$12,000
  • Soft-scape package (irrigation, garden beds, planting, turf), $12,000-$28,000
  • Paving 40m² travertine / bluestone, $8,000-$18,000
  • Retaining wall (structural, engineered), $650-$1,400 per m² face
  • Full backyard refresh (soft + hard), $28,000-$65,000
  • Full landscape design + hard-scape build, $70,000-$120,000+

Adelaide climate + soil, what breaks a landscape

Reactive clay soil across much of metro Adelaide moves seasonally. Paving laid on unstabilised clay will heave and gap within 24 months. Retaining walls without proper drainage weep-holes and geo-fabric will bulge or fail. The four Adelaide-specific line items every quote should carry: (1) compacted road-base under all paving, (2) ag-drain behind every retaining wall over 600mm, (3) soil-improvement in garden beds (not just topsoil dump), (4) a proper irrigation controller with drip lines, not popup sprinklers on clay.

PlanSA approvals + neighbour rules

Retaining walls over 1m usually trigger development approval. Fences that double as retaining walls need a neighbour consent under the Fences Act (SA) or Fences Act 1968 (VIC). Structures like pergolas within a certain setback of the boundary trigger their own approval. Your landscaper should own the PlanSA lodgement, not you. If they say "no approval needed, don't worry", you're the one who gets the council letter.

How to shortlist a Adelaide landscaper

Landscape is unregulated (no mandatory licence for pure soft-scape) but hard-scape work above $12,000 in SA and above the DBI threshold in VIC needs an appropriately licensed / registered builder. Insist on:

  • Verify Consumer and Business Services (CBS) registration for hard-scape and retaining
  • Ask for 3 completed jobs in your suburb, walk one if you can
  • Insist on a fixed-price contract with itemised drainage line-items
  • Confirm Building Indemnity Insurance (BII) certificate for anything over $12,000
  • Get the soil / drainage strategy in writing before the deposit
  • Separate design fee from build fee, you own the design if you pay for it

Frequently asked questions

Concrete sleepers slot into steel posts, resist rot, termites and fire, and are the long-life choice for structural retaining on reactive Adelaide clay, at a higher upfront cost. Timber sleepers are cheaper and look warmer but will eventually rot in the ground even when treated, typically lasting 10 to 20 years. For anything structural or over about 600mm, most Adelaide landscapers now recommend concrete sleepers or a block wall; timber suits low, decorative garden edging.

The villain to watch on this job

Reactive clay and cracked walls: The clay under the house swells when wet and shrinks when dry, and the footings ride up and down with it. The cracks are the house trying to keep up.
