How an architect can combine Notion AI and Midjourney to cut quote turnaround by 50%
Julien, an independent architect in Bordeaux, cut quote preparation time by 50% combining Notion AI for brief writing and Midjourney for fast concept visuals. 8 hours saved per project.
An architecture project rarely starts with drawings. It starts with a commercial proposal: project brief, aesthetic vision, budget estimate, timelines. For Julien, an independent architect in Bordeaux, this quoting phase averaged 12 to 15 hours per project, with a large portion spent drafting the project brief and producing mood boards to convince the client.
By combining Notion AI for writing and Midjourney for visuals, he cut this phase by 50%, recovering 6 to 8 hours per project reinvested in billable execution or new client acquisition.
The Hidden Cost of the Quoting Phase
The quoting phase is often unbilled or underbilled. An independent architect who spends 12 hours preparing a quote for a project that does not proceed has lost a day and a half of billable time. According to a 2025 survey by the French Order of Architects, independent architects spend an average of 22% of their working time on unconverted commercial proposals.
Reducing this time without sacrificing proposal quality is a direct lever on profitability.
Julien's Workflow with Notion AI
Julien has created in Notion a set of brief templates by project type: residential renovation, extension, new construction, commercial space rehabilitation. Each template includes standard sections (context description, functional program, regulatory constraints, budget estimate, schedule).
With Notion AI, he now fills these templates by dictating notes after the site visit. He tells Notion AI: "Write the functional program from these notes: family of 4, 140 sqm, open kitchen onto living room, add master bedroom with en-suite bathroom." Notion AI produces a structured first draft in 2 minutes, which Julien refines in 15 minutes rather than writing from scratch in 2 hours.
Visual Production with Midjourney
One of the most time-consuming parts of the quoting phase was producing mood boards. Julien used to spend 3 to 4 hours searching Pinterest references and formatting them in a Canva presentation.
With Midjourney, he directly generates concept visuals suited to the project in 20 to 30 minutes. He describes the desired atmosphere in English ("Haussmann apartment renovation, Paris style with modern touches, warm wood, white walls, natural light, 4K architectural photography") and obtains several proposals in under 2 minutes.
He selects the best ones, integrates them into his Notion presentation, and submits them to the client to validate aesthetic direction before investing in 3D renders.
Results After 6 Months
Julien applied this workflow to 18 projects over six months. Average quote preparation time dropped from 13 hours to 6.5 hours, a 50% reduction. On a base of two new projects per month, that represents 13 hours saved monthly.
His quote-to-contract conversion rate also improved by 4 points, with Midjourney visuals helping clients visualize more easily and validate aesthetic direction from the first presentation.
What This Workflow Does Not Cover
Midjourney generates concept images, not drawings. Notion AI produces text, not technical documents. Both tools accelerate the commercial phase, but the execution phase (drawings, 3D models, planning permission file) remains fully handled with Julien's usual technical tools.
Setup with Expert Support
Julien set up this workflow in two days with a consultant. The first day focused on creating Notion templates and configuring Notion AI. The second day on building a Midjourney prompt library for his usual styles and training on rendering parameters.

Frequently asked questions
Are Midjourney visuals precise enough to present to clients?
Midjourney visuals are concept images, not technical drawings. They allow quickly validating an aesthetic direction with a client before investing in professional 3D renders. For projects that progress, tools like SketchUp, Revit, or Archicad take over.
Can Notion AI generate project briefs compliant with building standards?
Notion AI generates text content from your templates and notes. Compliance with standards (DTU, Eurocodes, thermal regulations) remains your responsibility. AI accelerates the descriptive writing phase, but technical review is non-delegable.
Do you need a paid Midjourney subscription for professional use?
Yes. Commercial use of Midjourney-generated images requires a paid subscription (from 10 dollars per month). Images generated with a free account cannot be used for commercial purposes under the terms of service.
How long to master Midjourney prompt writing for architecture visuals?
Half a day of practice is enough to master the basic parameters. Julien has built a library of template prompts for his usual styles (contemporary, industrial, Mediterranean), letting him generate a satisfactory-quality visual in under 5 minutes.
Does this workflow work for a 3-to-5-person architecture firm?
Yes, and the effect is even more pronounced. Notion allows sharing brief templates between collaborators, and the Midjourney prompt library becomes a shared asset that homogenizes the visual style of client presentations.
