Landscape Design Proposal: Write Concept, Scope and Fees With AI

A landscape design proposal needs five parts: the client's brief in your words, a concept that answers it, a scope split into stages with deliverables, fees by stage with rules for revisions and extras, and terms. AI can draft the concept and scope from your notes. You set and check the fees, because it cannot know your time.

The usual failure is not the writing. It is a scope line like "design the garden" with no deliverables, no revision limit and one lump sum. The client then asks for a fourth layout and you have no basis to say no or to charge. The fix is to define each stage by what the client receives, and to say how many rounds of changes each stage includes.

Design-only or design-build: decide this before you write

The two routes need different proposals, so choose, or offer both, before the first sentence. Design-only means the client buys drawings and a specification and appoints contractors. Design-build means you design and then build, usually in two stages.

My tutorial on a two-stage design-build fee letter goes deeper on the second route. In this one the proposal offers both options, because it is common for a client not to know which they want until they see the price of each.

Twelve brief questions that make the proposal easy to write

A proposal is only as good as the brief behind it. Ask these at the first visit, write the answers down in the client's words, and treat any answer you cannot get as a risk to the fee.

1. Who will use the garden, how often, and are there children, pets or regular guests?
2. What must it have, and what would be nice to have, in order?
3. What do you want to stop having? What annoys you about it now?
4. How much upkeep will you do, and will someone else be paid to garden?
5. What is the build budget as a range, and does it include groundworks and planting?
6. Is there a date that matters, such as a family event or the end of a school term?
7. What cannot change: trees, boundaries, drain covers, a shed?
8. Where does water collect, and where is it sunny, shaded or exposed?
9. Who decides? If two people decide, who gives you the consolidated comments?
10. Which gardens or photos do you like, and which do you dislike?
11. Any allergies, or concerns about plants that are harmful to children or pets?
12. Do you want us to manage the build, or will you hire a contractor?

Add the site questions you answer yourself: gate width for machines, services you can see, and the fall across the site. Paste the answers into the assistant and ask it for a one-page brief that lists any contradictions, such as "low maintenance" next to a large vegetable plot. A contradiction found now costs nothing; one found at Stage 3 costs a revision round.

The job: a sloping family garden with a wet corner

Illustrative job: a rear garden of about 120 m² (roughly 1,300 square feet) that falls about 1.2 m from the house to the back fence and faces south-west. A family of four and a dog. They want a dining terrace for eight, a lawn the children and dog can use, a vegetable corner, planting that screens neighbouring windows, and a fix for the soggy lower corner. The build budget is $60,000 to $70,000, and they would like to use it by next summer.

Concept: the prompt, the draft and the corrections it needs

You are helping a landscape designer write the concept section of a proposal.
Use only the brief below. Write about 150 words in plain English, in three or
four short paragraphs, describing how the garden could be arranged: zones, how
they connect, materials in general terms, the feel.
Brief: 120 m2 rear garden falling 1.2 m from house to fence, faces south-west,
brick house. Family of four plus dog. Wants: dining terrace for eight, hard-wearing
lawn, vegetable corner, planting that screens neighbouring windows, a fix for a
wet lower corner. Build budget 60-70k. Both adults work: low upkeep.
Rules: do not name plants. Do not promise results or maintenance levels. Do not
say the drainage is solved; say a drainage approach will be developed. No
superlatives. Do not mention anything not in the brief.

Illustrative draft, before corrections:

Your garden becomes three connected outdoor rooms stepping gently down from the house. Closest to the kitchen, a generous porcelain terrace seats eight and catches the evening sun. Beyond it, a hard-wearing lawn forms a clear play and dog zone, edged by a curving bed of layered planting that screens the neighbouring windows and softens the boundary.

At the lower end, a productive corner holds raised vegetable beds beside a small wildflower meadow that thrives on neglect and needs no mowing. Level changes are handled with low retaining walls and broad steps, and the drainage solution removes the wet corner for good. Materials are a calm palette of warm grey stone, timber and brick that echoes the house. The result is a low-maintenance, family-friendly garden that adds value to your home.

The draft reads well and still breaks three of the prompt's rules: it promises results, declares the drainage solved and adds things the brief never mentioned. This is the usual pattern with proposals: the assistant writes marketing copy unless the prompt forbids it, and then still slips.

• "Wildflower meadow" was never in the brief. Delete it, along with "thrives on neglect and needs no mowing", which is a maintenance promise.
• "The drainage solution removes the wet corner for good" is a guarantee. Replace it with "a drainage approach will be developed in Stage 3 after the survey, with specialist advice if needed".
• "Adds value to your home" is a claim you cannot support. Delete it.
• "Porcelain terrace" chooses a material before the client has seen options. Say "a hard-surfaced terrace".
• "Low-maintenance" came from the client, so keep it, but as "designed for low upkeep" with no hours attached.

The corrected concept is shorter and safer, and it is what goes in the proposal. It keeps the three rooms, the terrace for eight, the lawn zone, the screening bed, the vegetable corner, the level changes by steps and low walls, and the colour palette taken from the house. Illustrative corrected version:

Your garden becomes three connected outdoor rooms stepping down from the house. Closest to the kitchen, a hard-surfaced terrace seats eight and catches the afternoon and evening sun.

Beyond it, a hard-wearing lawn gives the children and the dog a clear play space, edged by a bed of layered planting that screens the neighbouring windows.

The vegetable corner sits at the lower end. Level changes are handled with low retaining walls and broad steps, and a drainage approach for the wet corner will be developed in Stage 3 after the survey, with specialist advice if needed.

Materials will be chosen with you in Stage 3, in colours that sit well with the brick of the house, and the whole layout is designed for low upkeep.

Scope: stages, deliverables and what the client supplies

A scope that names deliverables protects both sides. For each stage say what the client receives, what you need from them and how many rounds of changes are included. The prompt for the scope draft gives the assistant your stages and nothing else to work with.

You are helping a landscape designer write the scope section of a proposal.
Use only the stages and hours below. For each stage write: what the client
receives (specific deliverables), what we need from the client, and how many
rounds of changes are included. Then list exclusions a client might reasonably
assume are included.
Stages: 1 Brief and survey (7 h). 2 Concept design (16 h): two layout options,
one presentation meeting, two rounds of changes. 3 Developed design (28 h):
one round of changes. 4 Construction information (20 h). 5 Site support (8 h):
two visits.
Rules: do not add stages or deliverables I have not listed. Flag anything
unclear instead of guessing. Put the answer in a table.

Illustrative result, tidied here into the table the proposal uses:

What needed correcting in that draft: the assistant added a "Stage 6, planting supervision" that was nowhere in the stage list, and it described the Stage 3 budget check as a "cost estimate", which turns a sanity check into something a client could hold you to. Delete the extra stage and rename the line "budget check against your stated range, indicative only". It also listed "unlimited phone support" under Stage 5, which becomes answers to contractor queries within the visit allowance.

Then list what is not included. In this example: a topographic survey by a surveyor, structural or drainage engineering, planning or other permissions (you advise, the client applies), contractor supervision and contract administration, 3D visualisations, tree surveys and soil testing. The exclusions list is where AI is most useful as a second pair of eyes: ask it what a client could reasonably assume is included that your stages do not mention.

Before and after, so you can see the difference a deliverable makes. Vague: "We will design your garden and provide plans." Precise: "Stage 2 gives you two layout options at 1:100 and one meeting of up to 90 minutes. After you choose one we include two rounds of changes, each based on one set of comments from you." The second sentence can be enforced in a friendly way; the first cannot.

Fees: build the number from hours, then check it three ways

Choose a fee structure first. A fixed fee per stage with an hourly rate for extras suits residential work, because clients can see what they buy and you are protected when the scope grows. Hourly with a cap suits a job whose scope is truly unknown. A percentage of build cost is easy to explain but ties your fee to a number you do not control. Whichever you choose, build the figure from hours so you know what the percentage or the fixed sum means in time.

Illustrative fee build-up at $90 an hour for the example job:

The proposal states the rate for extras ($90 an hour here), that expenses such as plotting and travel are charged at cost with an allowance of about $150, and that the fee is valid for 30 days. Payment follows the stages: the Stage 1 fee on acceptance, then each stage fee at the end of that stage, with Stage 5 invoiced as time is used up to the limit.

Design-only and design-build versions of the same fee

To offer both routes, keep the design fee the same and change what happens after Stage 3. Illustrative wording of the two options:

The credit period and the ownership of drawings if the client does not proceed are commercial choices, and the contract wording is for you and a lawyer to settle. Ask AI to draft plain-English versions of those two paragraphs, then have them checked.

Revisions, changes of mind and what counts as extra

Two things get confused. A revision is a change to the design within the brief, such as moving the terrace three metres. A change of brief is a new requirement, such as adding a swimming pool after the concept is approved. Revisions are counted by round; a change of brief restarts the work at the stage where it matters and is charged at the hourly rate.

Illustrative clause: "Each stage includes the rounds of changes shown in the scope. A round is one consolidated set of comments from the client. Further rounds, and any change to the agreed brief, are charged at $90 an hour after we confirm an estimate of the time in writing." Quick sum: a third round of changes at Stage 2 would take about five hours, which is $450. That is a number you can say aloud in a meeting without embarrassment, and having it written down is what makes that easy.

The human check of fees: seven questions before it goes out

1. Do the hours times the rate equal the fee on each line, and do the lines add up? Recalculate on a calculator. 7 + 16 + 28 + 20 + 8 is 79 hours, and 79 times $90 is $7,110.
2. Do the hours match what these jobs really take you? Compare with your timesheets for the last three similar gardens. If they averaged 92 hours, you are under-pricing by 13 hours, or $1,170.
3. What is the effective rate once unpaid time is counted? If you spend 4.5 hours on the first visit and writing the proposal and are not paid for it, $7,110 over 83.5 hours is $85.15 an hour, about 5% below your $90.
4. Is the fee sensible against the client's budget? It is 10.9% of $65,000 for design-only. Use that as a sanity check against your own history, not as a target.
5. Does every stage in the fee table appear in the scope, and the reverse? A deliverable with no fee line is free work.
6. Do the payment milestones add up to 100%?
7. Are extras, expenses and validity stated? Rate for extras, expenses at cost, the validity period, and a line saying whether tax is added to the fees.

The assistant can do a first pass on questions 1, 5 and 6 if you paste in the fee table and the scope table.

Here are my scope table and my fee table. Check them against each other.
List: any stage that is in one table but not the other; any line where hours
x $90 does not equal the fee; the total hours and total fees, showing your
working; any payment milestone that does not bring the total to 100%.
Do not suggest changes to the fees themselves.

It cannot do questions 2 to 4, which depend on your own records, and it should not suggest fee changes, because it has no idea what your time is worth.

Where an AI-drafted fee section goes wrong

Three realistic errors, all of which turn up when you ask an assistant to turn a stage list into a fee section.

The total does not add up. An illustrative draft headed the fee table with $6,950 when the lines sum to $7,110. The assistant had produced figures that looked right and did not sum them. Fix: recalculate every total yourself, and ask for the working so the error can be traced.

The text contradicts the scope. The draft promised "unlimited revisions to ensure you are delighted" while the scope table allowed two rounds. The assistant optimises for a warm tone. Fix: put the revision rules in the prompt and read the output against the scope table line by line.

The survey vanishes. If the stage list you paste in leaves out the measured survey, the draft will happily omit it, and you will be on a hillside at Stage 1 with eight unpaid hours. Fix: have a person list the deliverables and then ask AI what a client might assume is included that is not.

For the general habit of checking numbers that an assistant produces in proposals, see my tutorials on AI proposal mistakes that cost you the job and, for the visual side of concept work, AI garden design visuals in quotes. If you are a landscape architect rather than a designer-builder, the AI tools tutorial for landscape architects covers planting plans and renders.

What the client signs, and the first payment

End with an acceptance block that is short enough to read: the option chosen, the fee, the payment schedule, a line that the proposal is valid for 30 days, and a place for a signature and date. Illustrative wording: "I accept Option [A or B] on the terms in this proposal. I understand the fee is $[amount] and that the first payment of $[amount] is due on acceptance, before the Stage 1 visit." Plan on about an hour and a half of your own time for a proposal like this one, nearly all of it spent checking: the brief answers, the concept corrections, the scope against the fee table, and the arithmetic.

Questions about landscape design proposals

Should I charge for a landscape design proposal?

A common approach is to send the proposal free and charge from the first paid stage, which is usually the brief and survey. What matters is that the free part is short and the paid part starts before you do any real design. A proposal that takes six hours to write and ends in no deposit is a cost you should count when you set your rate.

Is a percentage of the build cost a good fee basis?

It is easy to explain, but it ties your fee to a number you do not control and it rewards a bigger build, not a better design. I would build the fee from hours by stage and then use the percentage of the client's budget as a sanity check, not as the method.

Can AI choose the plants for my concept?

It can suggest plants, but it does not know your climate, soil, supplier stock or the client's allergies, so every name needs checking by you. Use AI for the narrative in the concept, such as the zones and the feel, and keep plant selection in your own hands until the planting plan stage.

How many revisions should a proposal include?

Pick a number and state it by stage. A common pattern is two rounds of changes to the chosen concept and one at developed design, with each round meaning one consolidated set of comments. Anything beyond that, or a change to the brief itself, is charged at your hourly rate for extras.
