Give the AI your project notes and numbered photos, then ask for a case study in four parts: brief, challenge, solution, result. Every sentence must trace to a note or a photo, so you supply the results, the AI shapes the writing, and you confirm photo rights and client permission before publishing.
A gallery shows what you made. A case study shows how you think, and prospective clients scan it for a project like theirs and for proof that you solved the same kind of problem. AI is good at turning a pile of notes and photo captions into readable prose. It is poor at the part clients care about most, the result, which it will happily invent. The method below is built around that weakness: the AI writes only from facts you supply, and results come from you.
What a case study page does that a gallery cannot
A workable length is 400 to 700 words with six to ten photos, each captioned, which is my suggestion and not a standard. Open with a snapshot box (project type, size, duration, your role and, if the client agrees, a budget band), then four parts in a fixed order. The order matters because it is the order a prospective client's questions arrive in.
| Part | What goes in | Where the facts come from | The AI's job |
|---|---|---|---|
| Brief | What the client asked for, in their own words where possible | The intake notes or questionnaire | Condense to two or three sentences |
| Challenge | The constraints that made it hard: light, structure, budget, time, existing pieces | Your survey notes and the first photos | State them plainly without drama |
| Solution | Three or four decisions, each with its reason and a photo | Your decision log | Write the reasoning you supplied; add none of its own |
| Result | What changed, in measurements, delivery facts and the client's own words | Your records and the client | Nothing creative: arrange the facts you give it |
The last column carries the whole method. In the first two parts the AI can condense. In the solution it can only phrase reasons you wrote down. In the result it may not add a single word of substance, because every outcome statement a prospective client reads is one you have to be able to defend. If you already ran a questionnaire at the start of the project, the brief part is largely written, and interior design client questionnaire: build and summarise it with AI shows how that brief gets made.
One project note holds everything the AI may say
The raw material is a single note per project, written while the job is fresh. It has the facts, the reasons behind each decision, the results, a numbered photo list and the permissions. Here is one for the worked example, a front living room that had to serve a family of four. All figures are illustrative.
PROJECT NOTE (illustrative)
Project: front living room, family home (two adults, two children)
Size: 4.2 m x 5.1 m, about 21 m2. North-facing, one window 1.1 m wide.
Our role: design, joinery drawings, supplier sourcing, site visits
Duration: 11 weeks on site. Handed over on the agreed date.
Budget band (client agrees to publish): $26,000 to $30,000
Brief, client's words: "We want one room that works for the four of us in the evening: sofa time, homework, and somewhere to put the toys away."
Constraints: chimney breast on the right-hand wall; radiator under the window; no storage; old two-seater sofa and one armchair seated three
Decisions and reasons:
1. Joinery in both alcoves. Left: desk with two stations. Right: closed storage, 2.4 m of base units with doors. Reason: toys vanish at the end of the evening; homework has a place that is not the sofa.
2. Warm off-white walls, deeper clay on the chimney breast. Reason: north light is cool, so warm tones stop the room feeling cold; the darker breast gives the room a focal point.
3. Three layers of lighting: ceiling light on a dimmer, wall light by the desk, floor lamp by the sofa. Reason: the room can move from homework to relaxing without one bright overhead light.
4. Modular sofa. Reason: seats six and can be rearranged for films or visitors.
Results (facts only): seating for six, was three; 2.4 m closed storage, was none; desk for two children; handed over on the agreed date; final cost within the band
Client quote (permission given): [client's words]
Photos: 1 before, whole room; 2 before, window wall; 3 after, whole room; 4 after, left alcove desk; 5 after, right alcove storage; 6 after, desk detail; 7 after, chimney breast paint; 8 after, dusk with all lights on
Credits: joinery [workshop]; paint [brand, colours]; sofa [maker]; photography [photographer]
Permissions: client yes (photos, text, budget band, no street); photographer's licence covers website and socialThe reasons beside each decision are the most valuable lines on the page, because "why" is the one thing a gallery cannot show and the one thing the AI cannot know. Write them on site, two lines per decision, in a notes app. A reason recalled six months later tends to arrive polished and slightly wrong. The results line holds measurements and delivery facts only, and the photo list gives every image a number and a label so the AI can refer to them without guessing which is which.

Buy nowPass one: describe the photos literally
Do not ask for a case study yet. First have the AI describe the photos and compare what it sees with the note. This pass catches misreadings before they are woven into prose, and it doubles as a privacy scan.
Attached are eight photos of one room, numbered as in the project note. For each photo, describe only what is visible: layout, furniture, finishes, colours, lighting and any people or personal items. Then compare your descriptions with the project note and list every place where they disagree. Do not write any marketing text yet.Illustrative output, shortened:
- Photo 1: narrow living room, grey carpet, a small sofa and one armchair, a radiator under a single window, a chimney breast on the right-hand wall, no storage visible.
- Photo 3: the same room with warm off-white walls, a deeper clay chimney breast, units in both alcoves, a large corner sofa, a floor lamp and a rug.
- Photo 5: right-hand alcove with closed cupboards in a pale oak finish.
- Photo 8: the room at dusk with ceiling light, wall light and floor lamp on; a child's drawing and a school bag are visible on the desk.
- Disagreements: the note says the sofa is modular but photo 3 shows what looks like a fixed corner sofa; photo 5's finish is not in the note.
Three actions follow. Confirm with your own records that the sofa is modular and arranged as a corner, and keep the claim only if so. Add the joiner's specification for the finish instead of letting the AI's "pale oak" stand, since it was a guess from a photo. And deal with the drawing and school bag in photo 8, either by retaking the shot or by checking the client is comfortable, because a child's drawing is the kind of personal detail that a reader of the page may notice and the client may not.
Pass two: the case study, written from the note
With the descriptions confirmed, ask for the case study. The prompt closes the usual gaps in advance: invented results, praise adjectives and credits the AI made up.
Write a portfolio case study from the project note and the confirmed photo descriptions, 450 to 550 words, in four parts: Brief, Challenge, Solution, Result. Add a one-line snapshot at the top.
Rules:
1. Use only facts in the note. If a fact you want is missing, write [MISSING: what is needed].
2. In Solution, give each decision with the reason from the note and cite the photo number in brackets.
3. In Result, list only the facts under "Results (facts only)" and the client quote if one is supplied. Add no other outcome, no praise, and no claims about value, wellbeing or energy.
4. Do not use: stunning, transformed, dream, haven, oasis, curated, bespoke.
5. Plain, specific sentences. No exclamation marks.
6. End with a credits line using only the credits in the note.This is the edited version of what came back, which is the main worked example. The figures and names are illustrative, and the brackets show where your own details go.
A north-facing living room that works for four
Living room with built-in joinery, about 21 m², 11 weeks on site. Our role: design, joinery drawings, supplier sourcing and site visits. Budget band: $26,000 to $30,000.
Brief. The family of four asked for one room that works in the evening: "sofa time, homework, and somewhere to put the toys away."
Challenge. The room faces north and gets its daylight from one window 1.1 m wide, with a radiator beneath it and a chimney breast on the right-hand wall [Photos 1 and 2]. There was no storage, and the old two-seater sofa and armchair seated three. The budget had to cover joinery, a new sofa, lighting and decorating.
Solution. We used both alcoves for joinery [Photos 4 and 5]. On the left is a desk with two stations, so homework has a place that is not the sofa. On the right are 2.4 m of closed base units, so toys disappear at the end of the evening. North light is cool, so we painted the walls a warm off-white and the chimney breast a deeper clay [Photos 3 and 7], which warms the room and gives it a focal point. The lighting works in three layers: a ceiling light on a dimmer, a wall light by the desk and a floor lamp by the sofa [Photo 8], so the room can move from homework to relaxing without one bright overhead light. A modular sofa seats six and can be rearranged for films or visitors [Photo 3].
Result. The room now seats six, where it seated three. There is 2.4 m of closed storage where there was none, and a desk for two children. The work was handed over on the agreed date and the final cost stayed within the budget band. [Client's words, with permission.]
Joinery by [workshop]. Paint by [brand, colours]. Sofa by [maker]. Photography by [photographer].
Five edits turned the first draft into that version, and each one is a pattern to watch for.
- The Result opened with "a stunning transformation that makes every evening easier". Praise with no measurement behind it went, and the facts replaced it.
- It added "increasing the home's value". Nothing in the note supports that, so it was deleted.
- It wrote a client quote ("It's the best room in the house") that nobody said. The placeholder shows where a real quote goes, and only if the client agrees. Rule 1 had already made it write [MISSING: client quote] once, which is the behaviour you want.
- It called the sofa "bespoke", where the note says modular.
- It cited photo 6 for the lighting, but photo 6 is the desk detail. Check every bracketed photo number, because a wrong citation tells a visitor the image does not show what the text says.
Results without inventing any
Results come from three places and no others: measurements, delivery facts and the client's own words. Anything else needs evidence you hold and a client who agrees to its publication. The table shows the lines AI drafts tend to produce and what each should become.
| Weak result line | Why it fails | What to write instead |
|---|---|---|
| "A stunning transformation" | Praise with no evidence behind it | "Seating for six where there was seating for three" |
| "Maximised storage" | Vague and unmeasured | "2.4 m of closed storage where there was none" |
| "A smooth, stress-free project" | A claim about the client's experience | A real quote from the client, or "handed over on the agreed date" if that is true |
| "The client loved it" | Reported feelings with no source | A quote with permission, or leave it out |
| "Added value to the home" | A financial claim | Leave out unless a valuer's figure is on file and the client agrees to publish it |
| "On time and on budget" | Needs proof in both directions | "Handed over on the agreed date; final cost within the $26,000 to $30,000 band", if the records say so |
If a project has no measurable result, say what changed in observable terms: the layout, what was kept, what was added. A modest true result beats an impressive false one, because visitors often spot puffery and it undermines the rest of the page. Awards and press mentions go in only when they are real, with the date and the name of the publication.
Photo rights and permission, checked before the page goes live
Several parties can have a say in a single portfolio photo. Run through the table for every project, and keep the evidence in the project folder so that a question next year takes a minute to answer.
| Who | The question | Evidence to keep |
|---|---|---|
| The photographer | Who owns the photos, does the licence cover your website and social accounts, and is a credit required? | The written licence or commission terms |
| The client | Did they agree in writing to the photos, the text, any budget figure and the level of detail about their home? | Their emailed or signed approval of the final page |
| People and personal items | Are faces, children, family photos, documents or mail visible? | Cropped or retaken photos, plus the client's approval if anything remains |
| Third-party work | Is a recognisable artwork, designer piece or supplier logo prominent, and do you need permission or a credit? | Permission where needed, and credits copied from the note |
| Edited or rendered images | Has anything been added, removed or changed beyond ordinary retouching, and is any image a render? | A label on the image and in the text, with the originals kept |
Two practical points follow. First, rights belong in the contract as well as in an email trail: a clause that lets you photograph and publish the finished project, with the client's right to withdraw consent, is worth asking a lawyer to draft, and can AI draft an interior design contract, and which terms need a lawyer's check covers the ground. Second, a photographer's licence is often limited by use, so website use may be covered while advertising or competition entries are not. Get the scope in writing, and see photography usage rights: draft client licence wording with AI for the wording.
Uploading client photos to an AI tool is also a small act of sharing personal data. Check your plan's training setting (business plans such as ChatGPT Business and Claude Team do not train on content by default, and individual plans offer an opt-out) and crop out faces and documents before you upload.
Making each page findable without making it generic
Google's image guidance calls alt text the most important attribute for an image, asks for useful, information-rich descriptions that use keywords appropriately, and warns against stuffing. It also recommends short but descriptive file names instead of names like image1.jpg, and images placed near relevant text, because captions and surrounding words help it work out what a picture shows. For a case study page that translates into a short routine.
- Title: the project type, the constraint and your studio, for example "North-facing living room with built-in storage | [Studio]". One H1, and a heading for each of the four parts.
- Alt text: one plain sentence per photo about what is visible. Your pass-one descriptions are the raw material.
- File names: living-room-alcove-desk.jpg, not IMG_4821.jpg.
- Captions: a line beside each image, taken from the numbered photo list.
- Links: from each case study to the service page it proves, and to one related project.
The scaled-content rule applies here too. Google's spam policies treat generating many pages without adding value for users as scaled content abuse, however the pages are produced. One page per project, each carrying facts only that project has, is exactly what the project note guarantees. Ten near-identical pages with the room name swapped would be the opposite. If your site is built on Wix, Wix AI portfolio builder: a portfolio site for a freelancer or studio covers laying the pages out.
Three other shapes: one room, styling only, a project that slipped
Not every project fits the four-part page. Three variations come up often enough to have their own rules.
The one-room job. Use a short form of 150 to 250 words: one sentence of brief, two decisions with reasons, one measurable result. Illustrative output:
Guest bedroom refresh, about 11 m², three weeks. Brief: a spare room that sleeps two adults and works as a study. Decisions: a sofa bed instead of a double bed, so the room is a study by day [Photo 2]; blackout blinds behind linen curtains, because the room takes the early sun and guests often sleep late [Photo 3]. Result: the room sleeps two and has a desk for one. Finished in three weeks.
The styling-only job. The risk is over-claiming scope. The snapshot's "our role" line is copied from the note and the AI may not broaden it: "Styling and furnishing only. Building work and joinery by others." A visitor who sees that line trusts the rest of the page more, and a client who commissioned only styling is not credited with, or blamed for, work that was someone else's.
The project that slipped. In one illustrative case a supplier delayed the sofa by six weeks. The honest version of the challenge reads: "The sofa arrived six weeks late. We placed a loan piece so the family could use the room, and photographed once the sofa arrived." AI tends to smooth over delays, so add a rule to the prompt: "Include any delay or change that affected the outcome, without naming a supplier as the cause." A page that admits one problem and shows how it was handled is more believable than a page where nothing went wrong.
Choosing which projects to publish first
You will usually have more finished projects than the time to write them up, so score them. Give each project 0 to 2 on four criteria: usable photos (2 for a sharp set with before, after and details), permission (2 for written and complete), results on file (2 for measurements and delivery facts recorded), and fit with the work you want more of. Here is the scoring for six illustrative projects.
| Project | Photos | Permission | Results on file | Fits next work | Total |
|---|---|---|---|---|---|
| A. Family living room | 2 | 2 | 2 | 2 | 8 |
| B. Hallway refresh | 2 | 2 | 1 | 1 | 6 |
| C. Café fit-out | 1 | 0 | 1 | 2 | 4 |
| D. Friend's bedroom | 1 | 2 | 0 | 1 | 4 |
| E. Kitchen refresh | 2 | 1 | 2 | 2 | 7 |
| F. Whole-house renovation | 1 | 2 | 2 | 2 | 7 |
The decision follows from the totals. Publish A, E and F first, then B. Hold C until the permission arrives, because a high-fit project with no permission is a draft and nothing more. Hold D until you can document a result, since a page without one reads thin. The scores also tell you what to fix: project E loses a point on permission, which is a single email, and project F loses one on photos, which may be a reshoot worth paying for.
A final read, and how to tell whether the page works
Before publishing, read the page aloud and trace every sentence to a line in the project note or a numbered photo. Check each name and supplier spelling, every bracketed photo number, each alt text and each credit. Then send the finished page to the client for approval, keeping their reply in the project folder with the photographer's licence. If you can spare 20 minutes with the client, a short interview produces better quotes than any prompt, and how to write case studies from customer interviews using AI shows how to run one.
After a few weeks, look at what the page did. Add "which project caught your eye?" to the enquiry form, note which case study pages enquirers visited, and compare. A project that draws enquiries but not the kind you want is a prompt to change the brief section; one that draws none may need better photos or a clearer title. Publishing is the start of the feedback, and the note makes each revision quick because the facts are already organised.
The same note and photos can feed a month of social posts, and interior design Instagram captions: a month of posts from photos with AI shows how to turn them into captions with credits and client permission handled.
