How to Price Landscape Design Projects Accurately

Learn how to price landscape design projects without leaving money on the table. Real methods, actual numbers, and hard-won lessons from 15+ years of practice.

Pricing is where most landscape architecture firms bleed money quietly and consistently. Not on bad projects — on good ones they underpriced in the proposal phase and never recovered from.

The Three Fee Structures Actually Worth Using

There are more fee structures than anyone needs. In practice, three cover nearly every project type a landscape architecture firm will encounter.

Hourly billing is the most transparent and the most contentious. Clients hate open-ended hourly arrangements, and honestly, they're right to. It transfers all schedule risk to them. Use hourly billing selectively — for studies, due diligence phases, or any scope that genuinely can't be defined yet. Bill against a not-to-exceed cap so the client has a ceiling.

Lump sum (fixed fee) is what most residential and mid-size commercial clients want. It forces you to do the work of scoping upfront, which is actually a discipline that improves your firm. The risk is yours if the scope creeps. The upside is that efficient teams can build real margin. Fixed fee works well when you've done similar projects before and your scope definition is tight.

Percentage of construction cost is common in public work and larger commercial projects. Typical ranges run 8–15% for full services depending on project complexity, size, and region. It aligns your fee with project scale, but it also means your revenue floats with contractor bids you don't control. If a client value-engineers the project after design, your fee drops even though your hours don't.

Most firms use all three depending on context. The mistake is defaulting to one structure out of habit.

How to Build a Fee from Actual Hours

The only reliable way to price a fixed-fee project is to build it from an honest hours estimate, then apply your rates. Start with phases: schematic design, design development, construction documents, bidding, and construction administration. Estimate hours per phase by role — principal, project manager, senior designer, junior designer, CAD technician.

Use your actual billing rates, not aspirational ones. If your senior designer bills at $145/hour internally and you're estimating 40 hours for design development, that's $5,800 in direct labor before overhead and profit. Apply your overhead multiplier — typically 1.5 to 2.0x for most firms — and your target profit margin on top of that.

The number that comes out is your cost-based floor. You should never go below it. Where you price above that floor depends on market conditions, client type, and how much you want the project.

Don't skip the construction administration estimate. CA hours are chronically underestimated and chronically unprofitable as a result. Budget CA at a minimum of 15–20% of your total design hours on projects with any construction complexity.

What Your Billing Rates Should Actually Be

If you haven't updated your billing rates in the last 18 months, they're probably too low. Labor costs have increased materially since 2022. A principal at a mid-size firm in a major metro market should be billing at $200–$275/hour. Senior designers typically run $130–$175/hour. Junior designers and interns range from $75–$110/hour.

These aren't universal — they vary by region, firm reputation, and project type. But if your rates are significantly below these ranges and you're in a competitive market, you're subsidizing your clients' projects with your firm's margin.

Raise rates annually, even modestly. A 4–5% annual increase is easier to absorb than a 15% correction after three years of stagnation. Tell existing clients in writing 60–90 days before the new rates take effect. Most won't push back if you've been delivering.

Scope Definition Is Where Pricing Gets Won or Lost

A fee is only as good as the scope it's attached to. Vague scope language is the most common reason fixed-fee projects go over budget internally. "Planting plan for rear garden" sounds clear until the client asks for three design alternatives, a lighting layout, and a revised plan after the contractor starts.

Write scope exclusions explicitly. List what is not included — number of design alternatives, number of site visits, number of revision rounds, whether irrigation design is in scope, whether you're providing AutoCAD files to contractors. Clients don't always read these, but when a dispute happens, your exclusions are what protect you.

Tie deliverables to specific formats and quantities. "Construction documents" means something different to every client. Specify sheet count ranges, scale, and what consultants are included. The more specific your scope language, the easier it is to price accurately and the easier it is to issue a change order when something falls outside it.

Change Orders: The Revenue You're Already Earning but Not Capturing

Most firms are terrible at issuing change orders. The work gets done, the client relationship stays warm, and the project ends up 20% over budget internally. Change order avoidance is a cultural problem as much as a process one.

The fix is mechanical. When a request comes in that's outside the original scope, document it immediately — even just an email to the client saying "This falls outside our current scope. I'll send a change order for X hours at our standard rate." That single sentence does two things: it creates a paper trail, and it trains clients to understand that additional requests have costs.

Price change orders at your standard hourly rate with a minimum — typically 2–4 hours. Don't discount change orders. You're already doing the work; discounting rewards scope creep.

On larger projects, build a change order log into your project tracking from day one. Review it at every internal team meeting. Know your running total of approved, pending, and potential change orders at all times.

Retainers and Payment Schedules That Protect Cash Flow

How you structure payment matters as much as what you charge. A well-structured payment schedule prevents the cash flow gaps that force principals to make bad decisions — taking on projects they shouldn't, delaying hires, or carrying receivables past 90 days.

For fixed-fee projects, a standard structure is 25–30% at contract execution, milestone-based payments through design phases, and a final 10–15% at project closeout. Never start work without a deposit. The client who pushes back on a deposit is telling you something about how the rest of the engagement will go.

For ongoing clients — municipalities, developers, repeat residential clients — a monthly retainer against a defined scope of services simplifies billing and improves your forecasting. Set the retainer slightly below your expected monthly average and bill overages hourly. This keeps clients from feeling nickel-and-dimed while protecting your hours.

Invoice on a fixed schedule, not when you remember to. Monthly invoicing on the first or fifteenth is easier to manage than project-milestone billing for most firms. It keeps revenue predictable and keeps clients from being surprised by large invoices.

Common Mistakes Firms Make When Pricing

Pricing to win instead of pricing to profit. Discounting your fee to beat a competitor's proposal is a strategy that compounds badly. You win a project at thin margin, the team is stretched, quality suffers, and you've trained the client to expect low fees.

Not tracking actual hours against estimates. If you don't know whether your last five projects came in over or under your hour estimates by phase, you're pricing the next project blind. Time tracking isn't just for billing — it's the feedback loop that makes future pricing accurate.

Lumping CA into design fees without budgeting it separately. Construction administration is a distinct service with distinct risks. Price it separately, track it separately, and staff it accordingly. Firms that bundle CA into a flat design fee consistently lose money on it.

Using outdated overhead multipliers. If your overhead multiplier hasn't been recalculated in the last year, it's probably wrong. Overhead changes — rent, software subscriptions, insurance, salaries. Recalculate annually using actual numbers from your financials.

Writing scope that's too general to defend. "Full design services" is not a scope. When the client asks for something you didn't intend to include, you have no leverage to issue a change order if your contract doesn't define the boundaries clearly.

Ignoring reimbursable expenses. Printing, mileage, travel, consultant coordination fees — these add up on larger projects. Either include a reimbursable expense line in your fee or track and bill them separately with a standard markup (typically 10–15%).

How Phasewise Handles This

Phasewise is built around the reality that pricing accuracy depends on data from past projects. The platform connects your fee estimates to your actual tracked hours by phase and role, so you can see in real time whether a project is running over its budget. When you're building a new proposal, you can reference completed projects of similar type and scope to check whether your hour estimates hold up. It doesn't automate your pricing decisions — it gives you the information to make them better.
