The Interior Design Client Questionnaire: What to Ask Before Every Project

Every successful interior design project starts the same way: with a clear brief. And a clear brief starts with the right questions. Yet most designers still gather these details through scattered WhatsApp messages, half-finished emails and a couple of hurried phone calls — then spend hours piecing it all together.

A good client questionnaire fixes that. Ask the right things up front, in one place, and you walk into the project knowing exactly what your client wants, what they can spend, and when they need it.

Below is a complete interior design client questionnaire you can use before every project, grouped into the six areas that matter most.

1. The space

Start with the basics of what you're working with.

• What type of space is it (apartment, house, office, hospitality venue)?
• Which rooms or areas are part of this project?
• What is the approximate surface area?
• Is this a new space, a renovation, or a refresh of what's already there?
• Are there any structural changes planned (walls, layout, extensions)?

2. Lifestyle and needs

The same room serves very different people. This is where you learn who you're really designing for.

• Who uses the space day to day? Any children, pets, or elderly family members?
• How do they use each room — work, entertaining, relaxing, all of it?
• What frustrates them about the current space?
• What must the finished space absolutely have?
• Is there anything they want to keep (a piece of furniture, a view, a feeling)?

3. Style and aesthetics

This is the part clients find hardest to put into words — so give them anchors.

• Which styles appeal to them (minimalist, Scandinavian, industrial, classic)?
• Are there colours they love, or ones they can't stand?
• What atmosphere should the space create — calm, energetic, cosy, elegant?
• Do they have reference images or a saved collection to share?
• Are there materials or finishes they're drawn to (wood, stone, metal, textiles)?

4. Budget

Skipping this question helps no one. It's kinder — and more professional — to align early.

• What is the overall budget range for the project?
• Does it include furniture and décor, or construction only?
• Are they open to investment pieces, or focused on value?
• Is the budget fixed, or is there flexibility for the right result?

5. Timeline

• When would they like the project to start?
• Is there a hard deadline (a move-in date, an event, a season)?
• Are there phases, or should everything happen at once?

6. Practicalities

The details that prevent surprises later.

• Who are the decision-makers, and who signs off?
• How do they prefer to communicate, and how often?
• Are there access constraints, building rules, or an existing team of contractors?

Turn the questionnaire into a brief that works

A questionnaire is only useful if the answers come back complete. In practice, clients skip questions, misunderstand what you mean, or reply across three different channels — and you're left chasing.

The fix is structure: ask every question in one place, guide the client through it, and receive a single, organised brief you can act on. That's exactly what a structured briefing tool does — it takes the questions above, presents them clearly to your client (in their own language), and hands you back a complete, professional brief without the back-and-forth.

Once the answers are in, the next step is shaping them into a document that guides the project — see our guide on how to write an interior design brief. Get the brief right, and the rest of the project runs on solid ground.
