Landscape Design-Build Pricing: Design Fees, Hardscape, Planting, Lighting, and a $68K Backyard

Design-build is a different business than maintenance

If you run a maintenance crew and a design-build crew out of the same truck yard, the first rule of pricing is: they are two businesses. Maintenance is a recurring-revenue machine priced per cut and per month. Design-build is a project business priced per job with 35–50% gross margin.

Mixing them up is how landscape shops bleed money. Design-build crews end up cutting grass mid-project because schedules conflict. Maintenance crews get pulled off routes to help on big installs. Both sides lose productivity, and neither produces its expected margin.

Charge for design — always

The cheapest and most common mistake in landscape design-build is giving away the design phase. A proper residential design takes 8–25 hours of professional time: site visit, measurements, client goals interview, concept sketches, 2D plans, plant selections, revisions, and a final presentation.

Price the design separately. A reasonable 2026 range:

Most design-build shops credit the design fee back to the project if the client proceeds. This structure filters tire-kickers (they won't pay the design fee) and pre-qualifies buyers (they already wrote you a check for $1,500 before they've signed an install proposal).

Hardscape pricing per square foot

Hardscape pricing depends heavily on base prep depth and cut-in work. A 400-sq-ft flagstone patio with no curves, no step-downs, and existing sub-grade is a different job than the same material wrapping around tree roots with a 2-step elevation change.

Planting pricing: plant cost × 2.5 to 3

The standard pricing rule for residential plant installation is plant cost × 2.5 to 3. That covers the plant itself, your labor to plant it, soil amendments, staking (on trees), mulch, and warranty.

Add a separate line for soil amendment, planting, and mulch on large beds — roughly $4–$7/sq ft for prepared planting bed ready for plants.

Irrigation systems

A residential irrigation system is priced per zone, with adjustments for distance from the water source and control complexity. 2026 ranges:

• Per zone (standard lawn, 6–8 rotors or sprays): $650–$950
• Drip zone for planting bed: $450–$750
• Smart Wi-Fi controller: $395–$595 installed
• Rain sensor: $150
• Backflow preventer: $395–$595 (code required in most areas)
• Typical 6-zone residential system: $4,200–$6,800

Low-voltage landscape lighting

Lighting is where design-build margin hides. It's high-markup, high-impact, and clients love the before-and-after. Price it per fixture installed with wire and transformer included in the per-fixture rate when ordered in bulk:

• Path light (brass or composite): $145–$225 installed per fixture
• Uplight (well light or bullet): $165–$245 installed per fixture
• Downlight / moonlight (in tree): $265–$395 installed per fixture
• Transformer (300W, Wi-Fi enabled): $695–$995
• Design fee for lighting plan: $350–$750 (often waived on install)

A typical mid-size residential lighting package: 20–30 fixtures + transformer + controls → $4,500–$8,500. Margin on brass fixtures purchased at wholesale is excellent — often 60–70% gross.

Full project example: $68,000 backyard

• Design phase (10 hours + rendering): $2,400
• Demo existing patio (500 sq ft, haul): $2,800
• Grading + soil import: $3,500
• New paver patio (600 sq ft × $28): $16,800
• Segmental retaining wall (80 face sq ft × $45): $3,600
• 6-zone irrigation: $5,800
• Planting (3-gal × 40, 5-gal × 20, 15-gal × 6, perennials × 50): $8,100
• Soil amendment + mulch (900 sq ft beds): $4,500
• Landscape lighting (25 fixtures + transformer): $6,800
• Artificial turf in dog run (400 sq ft × $14): $5,600
• Project management, permits, crane day, buffer: $7,100
• Total: $67,000, rounded to $68,000 customer price

On a well-run job, this lands at 40–45% gross margin. The design fee is credited back against the total if the client proceeds.

Landscape design-build bid mistakes

1. Free designs. You're giving away $1,500–$4,000 of professional work. Charge for the design, credit on install.
2. Plant cost × 2 is not enough. The accepted multiplier is 2.5–3. Below 2.5, you're breaking even on plant work after labor.
3. Forgetting warranty. Include a 1-year plant warranty on 15-gal and larger trees as part of the price. Replacement cost averages 3–5% of plant subtotal — build that in.
4. Single-bid presentation. Landscape budgets are fluid. Present phased options (phase 1 patio + irrigation this year, phase 2 lighting + planting next spring) and let clients self-select.
5. No change-order process. Client says “could we add two more uplights?” on day 5. That's a change order at $225 × 2 + wire pull, not a freebie.
