Coding Liquids tutorial cover featuring Sagnik Bhattacharya for Interior Design Client Questionnaire: Build and Summarise It With AI.

Ask who lives in the home and how each room is used, which styles the client likes and rejects, a budget range with priorities, timing, and constraints such as structure, lease rules, pets and accessibility. Yes, AI can turn the answers into a one-page brief, provided you review it and the client has agreed to how their data is stored.

Questionnaires fail in two ways: they are too long to finish, or they collect answers nobody reads again. AI helps with the second. It is good at sorting thirty answers into a structure, quoting the client's own words and spotting contradictions between them. It is poor at taste, so the brief it writes must keep what the client said apart from what the AI guessed, and you review it before anyone else sees it.

Seven blocks of questions, and why each earns its place

Group the questions into blocks so the form feels like a conversation and the summary has a structure to fill. The questions below are samples to adapt, not a fixed list.

BlockSample questionsWhat it decides
1. The householdWho lives here, and what are the children's ages (ages only)? Any pets? Who works from home, and on which days? Does anyone need step-free access, or have needs that affect the layout?Finishes, storage and layout, since pets and toddlers change almost every material choice
2. Rooms and routinesFor each room: what happens there on a weekday and at the weekend? What annoys you now? What must stay exactly as it is?Turns "redo the kitchen" into jobs the room has to do
3. StyleThree words for how the home should feel. Two rooms or images you love, and why. Colours or materials you dislike. Pieces you own that must stay.Dislikes narrow the field faster than likes, and kept furniture anchors the scheme
4. BudgetA range rather than a figure. What does it include: furniture, building work, fees? What is fixed and what can flex? Is there a contingency?Stops a brief outrunning the money
5. ConstraintsStructural limits, lease or landlord rules, permissions, access for deliveries, heritage features, allergiesWhat is possible at all; found late, these become expensive surprises
6. Timing and decisionsDates that matter (a move, an event, a birth). Who decides? How do you prefer to receive updates?Deadlines, lead-time planning and the people who must agree
7. Documents and photosFloor plans, photos of each room, links to inspiration, earlier quotesEvidence behind the brief, and source material for mood boards

I would aim for about 30 questions in total; that is a rule of thumb, not a standard. If the full set feels heavy, split it in two. A short enquiry form (block 1, a one-line scope, a budget band and timing) goes to everyone who gets in touch, and the complete questionnaire goes only to clients who agree to proceed. That keeps the long form for people who are committed, and it keeps personal data you do not need out of your files.

Build the form in three prompts

AI is useful for the drafting stage and for tidying afterwards, in three short steps. First, ask for a draft aimed at your kind of project. Second, ask it to shorten the draft and strip jargon. Third, ask where answers should branch, so a client with no pets never sees the pet questions.

1. I am an interior designer who mostly does [whole-home refreshes / single rooms / new builds]. Draft a client questionnaire in seven blocks: household, rooms and routines, style, budget, constraints, timing and decisions, documents. Write each question in plain language a client would use. Ask for budget as a range. Do not ask for anything we do not need to design the space.
2. Cut it to the questions that change a design decision. Remove any question a client would struggle to answer without a designer's vocabulary.
3. Suggest which questions should only appear after a particular answer, and say which answer triggers each one.

For the form itself, Google Forms is free and handles most of this. Sections let you mirror the seven blocks, and the form can send a client to a different section depending on their answer to a multiple-choice or dropdown question, which is how the pet questions stay hidden. Checkbox questions cannot branch, so ask "Do you have pets?" as a yes/no multiple-choice question. One catch matters for block 7: a file upload question makes respondents sign in to a Google account, and the uploaded files land in a new folder in the form owner's Drive. If you expect clients without Google accounts, ask them to email photos instead, or check the upload rules of any paid form tool before you commit to it.

A filled-in questionnaire: one household's answers

The main example is a family house with an open-plan ground floor of about 38 m². These are one household's illustrative answers, shortened to the ones that matter. Names and addresses are left out on purpose, for reasons the consent section explains.

QuestionClient's answer
Who lives here?Two adults, a toddler aged two and a labrador. One adult works from home three days a week.
ScopeKitchen, dining and living areas, open plan, about 38 m². Hall and upstairs are not included.
A normal weekdayBreakfast at the island in a rush at 7am. The toddler eats at the table. Remote work happens on the sofa at present. The dog sleeps by the back door.
What annoys you now?No storage for toys, a dark room in the evenings, and mud tracked across the floor.
Three words for the feel"Warm, calm, lived-in."
Images you loveA kitchen with walnut shelves and a terracotta tiled splashback; a living room with a deep rust sofa.
DislikesCold greys, glossy cabinets, open shelving at toddler height.
Must stayThe blue sofa, bought two years ago, and a dining table from a grandparent.
Budget$38,000 to $46,000 including furniture and building work, fees separate. "Would stretch for the right worktop."
ConstraintsThe chimney breast stays because it carries a flue. The back door cannot move. Worktop height and drawer depth matter to one adult.
TimingFinished before a second baby arrives in nine months. Away for the first two weeks of August.
Who decides?Both. The adult who works from home leads on the kitchen; the other prefers options in writing.

Read the answers as a designer would and a few tensions jump out already. The client loves walnut shelves yet dislikes open shelving at toddler height. They own a blue sofa and admire a rust one. The budget has a soft edge. A summary that merely tidies these answers would hide all three, and a summary that resolves them for the client would be inventing a decision. The prompt below asks for neither.

The brief the AI gave back, and what I changed

Here is the one-page brief as a well-prompted AI returns it, close to its first form, with the tags the prompt asks for.

Project brief, Client A (draft for designer review)

Snapshot. Open-plan ground floor, about 38 m²: kitchen, dining and living areas. Budget range $38,000 to $46,000 including furniture and building work, fees separate [Stated]. Target: finished before a second baby arrives in about nine months [Stated].

Household. Two adults, a toddler aged two and a dog [Stated]. One adult works from home three days a week [Stated].

What the space must do. Fast weekday breakfasts at the island; a toddler-friendly place to eat; somewhere to work three days a week; a back-door zone that copes with mud; storage for toys [Stated].

Style. "Warm, calm, lived-in" [Stated]. Loves: walnut shelves with terracotta tiles, a deep rust sofa. Dislikes: cold greys, glossy cabinets, open shelving at toddler height [Stated]. Keeps: the blue sofa and a grandparent's table [Stated].

Constraints. The chimney breast stays; the back door position is fixed; away for the first two weeks of August; worktop height and drawer depth matter to one adult [Stated].

For the first meeting. Walnut shelves against the dislike of open shelving at toddler height [Conflict]. Blue sofa alongside rust-sofa inspiration [Conflict]. How far "would stretch for the right worktop" goes [Missing]. How a disagreement between the two decision-makers is settled [Missing].

It reads well because the prompt forced it to. I still changed four things, and the first draft is where they hid. It had summarised the style as "warm minimalist", a label the client never used; the AI had inferred it from the photos, so I replaced it with the client's own three words and moved the guess into the first-meeting list as [Inferred]. It had turned the budget range into "around $42,000", a midpoint nobody said. It had recommended luxury vinyl flooring for the dog and the toddler, which is a specification and not a brief, so I cut it. And it had written "one adult has a bad back", a health detail the design only needs in the form of worktop heights and drawer depths.

The prompt that keeps the AI to what the client said

Each rule below closes a gap the first draft showed. Paste the answers underneath the prompt, or attach the form's response sheet with the names and address removed.

Summarise the questionnaire answers below into a one-page design brief of no more than 350 words, for the designer's review.
Rules:
1. Tag every statement [Stated] when it comes directly from an answer, [Inferred] when it is your own conclusion, or [Missing] when an answer is blank or unclear. Quote the client's own words for style.
2. Keep ranges as ranges. Never turn a range into a single figure.
3. Do not recommend products, colours, materials or layouts. Record needs, not solutions.
4. List contradictions between answers under "For the first meeting", with the two answers side by side.
5. Leave out names, addresses and health details. Where an answer affects the design, state only the design effect, for example "drawer depth matters to one adult".
6. Finish with five questions the designer should ask first.

The tags do the real work. [Stated] lets you skim, because anything carrying it can be checked against the form in seconds. [Inferred] shows where the AI has gone beyond the client, which is where taste mistakes live. [Missing] stops blanks turning into assumptions. For wider prompt ideas around briefs and schedules, see ChatGPT for interior designers: ten prompts for briefs and schedules, and for the same questionnaire-to-brief idea in another trade, wedding planner client questionnaire: answers to a brief with AI.

Reading inspiration images without letting the AI decide taste

Block 7 invites photos and links, and an AI that reads images can describe them. But a picture of a kitchen the client loves is evidence of something, not of everything. Ask the AI to describe only what is visible and to keep every conclusion labelled.

Describe what is visible in each image: materials, colours, finishes, layout and lighting. Then list possible reasons the client might like it, each tagged [Inferred]. Do not tell me what the client wants.

Illustrative output for the two images in the example: "Image 1: off-white matt cabinets, walnut open shelves above a terracotta tiled splashback, a brass tap, two pendant lights over an island. Possible reasons [Inferred]: the warm wood, the terracotta accent, the shelves as a place to display things. Image 2: a deep rust velvet sofa, warm white walls, a wool rug, trailing plants. Possible reasons [Inferred]: saturated colour, texture, plants." Then put one question per image to the client: "What do you love most here: the colour, the shelves, or the way the room is laid out?" Their answer goes into the file as [Stated]. The AI's guess never does.

Two decision-makers, two sets of answers

When two people share a home, send blocks 2, 3 and 4 to each of them separately, with a note that there are no right answers. Paste both sets into the prompt and ask for a table of agreements and differences. For the example household it might come back like this, with figures and answers illustrative.

TopicPerson 1Person 2Status
Top priorityStorage firstThe island firstDiffer
Feel of the roomWarm and calmWarm and cosyAgree on warm
Work spaceA dedicated deskHappy to use the tableDiffer
The dogNeeds a back-door mud zoneNeeds a back-door mud zoneAgree

Nothing in the table decides anything, which is the point. It gives you a neutral way to open the first meeting, and it stops whoever filled the form in first from setting the whole brief. Keep each person's answers under their own label, and do not tell either of them what the other said unless both have agreed to share it.

Contradictions and gaps become the first meeting's agenda

The closing questions turn the conflicts into an agenda. For the example household the AI proposed these five, and I kept all of them with light edits.

  1. If open shelving is out at toddler height, would shelves placed well above a toddler's reach give you the walnut-and-terracotta look you liked in the photo?
  2. Is the blue sofa staying in the living area, and which colours can sit beside it?
  3. What does "the right worktop" mean in cost terms: how far above $46,000 would you go for it?
  4. When the two of you disagree about a finish, who has the final say?
  5. Which two weeks in August are off limits, and may trades work in the house while you are away?

A quick sum on time, with illustrative figures. Writing a brief by hand takes 30 minutes; with AI the run takes 5 minutes and the check 10, so 15 in all. Across 12 new clients a year that saves three hours, which is modest. The better return is that every conflict and gap is on paper before you meet the client, which is cheaper than finding them at the first presentation. The last question in particular feeds the schedule, and interior design project timeline: draft phases and lead times with AI shows how a hard date like the second baby shapes the phases.

Consent, storage and what stays out of the chat

A questionnaire collects personal information about people at home, so the handling matters as much as the questions. These habits are practical, not legal advice, and a qualified adviser should confirm what applies to your clients.

  1. Say what you do on the form. State what you collect, why, who sees it (you, and an AI tool you use to summarise), where it is stored and for how long.
  2. Ask for a tick. Put a required checkbox before the submit button so consent is recorded with the answers.
  3. Ask only for what the design needs. Accessibility needs can count as health information, which many data-protection laws treat more strictly, so ask "does anyone need step-free access or particular worktop heights?" and record the design effect only. For children, ask for ages, not names or photos. Never ask for identity or bank details.
  4. Strip identifiers before pasting. Replace names with Client A, delete the address and keep sizes, dates and preferences. How to anonymise client data before you paste it into AI walks through the steps.
  5. Check your AI account's training setting. Individual plans offer an opt-out from training on your chats, and business plans such as ChatGPT Business and Claude Team do not train on content by default. On a personal plan, find the model-training switch in the privacy or data settings and turn it off.
  6. Set a retention period and keep to it. Google Forms stores uploaded files in a folder in the form owner's Drive, so deleting the response sheet at the end of the period is not enough; delete that folder too.

Here is wording you can adapt for the form's introduction.

The answers you give here help us prepare your design brief. We keep them in our client files for [period] after your project ends. We may use an AI tool to summarise the answers, and we remove names and addresses before doing so. Only [names of the people who will see the answers] see them. You can ask us to delete your answers at any time. Tick to confirm you are happy with this.

If you have clients in the EU, data-protection law such as the GDPR applies to how you handle all of this, and a short conversation with an adviser about your privacy notice is money well spent.

A blank answer that became "flexible"

In one illustrative run, a questionnaire came back with the budget question empty. The first summary prompt had no [Missing] rule, and the brief said "budget flexible". Nobody noticed until the first scheme was presented and the client reacted to the total. The cause was the summary, not the client: a blank is information too, and it means "ask".

The fix is the [Missing] tag plus a follow-up that goes out the same day. A short version works: "Hello [first name], thank you for the questionnaire. One gap: the budget question was blank. A range is enough, and you can split furniture from building work if that is easier. It keeps the first scheme realistic." Keep it friendly and specific, and put the reply in the file before you design anything.

Once the brief is agreed, the next document is usually the proposal, and interior design proposal template: scope, fees and phases with ChatGPT picks up where this tutorial stops.

Questions designers ask about questionnaires and AI

How long should an interior design questionnaire be?

Long enough to settle scope, short enough to finish in one sitting. Many designers send a short enquiry form first and the full questionnaire once the client agrees to proceed. Use multiple choice for budget bands and similar answers, and keep open text for the places where you need the client's own words, such as how each room should feel.

Can AI read a client's inspiration photos?

Yes, ChatGPT, Claude and Gemini can describe images, but treat what they say about taste as a guess. Ask for what is visible, such as materials, colours and layout, and tag any conclusion as inferred. Then ask the client why they love each picture, because the reason matters more than the image. Claude takes up to 20 images per message on claude.ai, each up to 10 MB.

Do I need consent to use AI on a client's answers?

Tell clients you use AI tools to summarise their answers, what is shared and how long you keep it. Data-protection laws generally expect transparency and a lawful basis for processing personal data, so a clear privacy notice and consent wording are the practical steps. Ask a qualified adviser for wording that fits your business and clients.

Should the questionnaire ask about budget directly?

Yes. Ask for a range and what it includes, then what is fixed and what can flex. A client who skips the question needs a follow-up, not an assumption, so leave the gap marked as missing in the brief and cover it in the first meeting. Never let a summary turn a blank answer into a flexible budget.
