How to use the design brief generator

A good brief is the cheapest way to save time on a project. Most redesigns, fee disputes and budget shocks trace back to something nobody asked at the start: how many people really live in the house, whether the budget includes furniture, whether the client works from home, or who signs off decisions. This generator gives you a structured client questionnaire in seconds, organised in the order you'd normally run a briefing meeting.

  1. Choose the project type. A new house, an extension or renovation, an interior project or a commercial or workplace job each get their own questions about spaces and use.
  2. Pick the length. The short version keeps the two or three most important questions in each section, which suits an email before the first meeting. The full version is for a briefing workshop.
  3. Tick the sections you need. Leave out sustainability for a quick fit-out or the site section for an interior, for example.
  4. Add names for the client and project if you like, then copy the text or download it as a .txt file and paste it into your own letterhead, email or form tool.

What goes into a design brief

Brief = goals + budget + timeline + site + spaces + use + style + performance + approvals + decision-making

The sections follow the order of a typical RIBA Stage 1 or AIA Pre-Design conversation. Start with why the client wants to build and what success looks like, then pin down money and time, because those two shape everything else. Next come the site and any existing building, followed by the list of spaces and how people will use them. Style, materials and sustainability come later, once the practical needs are clear. Finish with approvals and how the client wants to work with you.

Worked examples

A rear kitchen extension

Choose "Extension or renovation", the full length and all sections except commercial use. The questionnaire asks which rooms are being changed, what isn't working now, whether the family will live in the house during the works, and whether there's a party wall or a conservation area. That's enough to start measured survey and feasibility work.

A pre-meeting email for a new house

Choose "New house" and the short length. You get about 20 questions covering goals, budget range, the plot, the number of bedrooms, the household and style references, short enough that clients will actually fill it in before you meet.

An office fit-out

Choose "Commercial or workplace" and untick the site section if the building is already chosen. The questions cover headcount now and in five years, desk ratios, meeting room needs, brand, IT and the lease end date.

Who this generator helps

  • Architects running Stage 1 or Pre-Design briefings and writing fee proposals.
  • Interior designers onboarding residential and hospitality clients.
  • Small practices and sole practitioners who don't yet have a briefing template.
  • Design-and-build contractors qualifying leads before a site visit.
  • Homeowners getting their thoughts in order before they talk to an architect.
  • Students practising client briefs for studio projects.

Practical tips

Once you have the brief, describe the room in a sentence and see it straight away with Text to Room, a fast way to check you've understood the client's style.

FAQ

Design Brief Generator FAQ

What is a design brief in architecture?

A design brief is the written statement of what the client wants a building or interior to achieve: the spaces and how they're used, the budget, the timeline, the site constraints, the look and feel, and any performance targets. It's the reference the architect designs against and the yardstick the client uses to judge the result.

What should a client questionnaire for an architect include?

At a minimum: project goals, budget and how it's funded, the target timeline, information about the site and any existing building, a list of rooms or spaces with sizes, how the household or business uses the space, style preferences, sustainability goals, accessibility needs and how the client wants to communicate and make decisions.

When should the design brief be written?

In the RIBA Plan of Work it's developed during Stage 1, Preparation and Briefing, and finalised before Concept Design. In the AIA phases it's part of Pre-Design or programming. Getting it agreed early avoids redesign later, which is one of the biggest causes of delays and fee overruns.

Should I send the questionnaire before or after the first meeting?

Many architects send a short version before the first meeting so the client can think about budget and priorities, then go through the full questionnaire together in a briefing workshop. Clients often answer more honestly about budget and lifestyle when they've had time to think.

How many questions should a design brief questionnaire have?

For a house or extension, 30 to 50 focused questions is usually enough. A short pre-meeting version might have 10 to 15. For commercial or public projects, a briefing document often grows into a detailed room data schedule, but it still starts with the same core questions.

How do I get clients to be honest about their budget?

Ask for a range and whether it includes fees, VAT or sales tax, furniture and contingency. Explain what typical construction costs per square foot or square metre are in your area, so the client can see whether the brief and the budget match. A quick estimate with a construction cost calculator helps.

Can I edit the generated questionnaire?

Yes. The questionnaire is plain text, so you can copy it into your email, a Word or Google Docs template or a form tool, or download it as a text file. Add your logo and practice details and remove any sections that don't apply to your project.

Is this design brief generator free?

Yes. It's free with no sign-up, and everything is generated in your browser. Nothing you type, such as client or project names, is sent to a server.
