Interior Designers: Protect Your Judgement When Using AI Tools
When you start a project by feeding a brief into Midjourney, you risk letting the AI's visual output become your design direction instead of your own spatial thinking. Your clients book you because you understand how a room feels to live in and what materials will age well, not because you can prompt an image generator. The real threat is not AI replacing you, but your own expertise quietly disappearing as you spend more time curating AI renderings than developing genuine design concepts.
These are suggestions. Your situation will differ. Use what is useful.
Brief First, Mood Boards Second
Many designers now open Midjourney before they have fully understood the client's actual needs. This backwards workflow means AI aesthetic choices shape your thinking instead of your thinking shaping the mood board. Spend time with your client discovering what they genuinely want the space to do before you generate a single image. Only after you have clear spatial intentions and material preferences should you use AI to visualise those intentions.
- ›Write down three specific spatial outcomes the client wants before opening any AI tool
- ›Sketch rough material and colour ideas by hand or in mood boards from real reference images first
- ›Use AI to test how your existing design direction looks in different lighting, not to generate the direction itself
Know What Your Renders Are Actually Hiding
Adobe Firefly and Planner 5D AI renders look photorealistic, but they hide the problems that only exist in actual spaces. Soft furnishings never hang the way they do in renders. Light at 9am is completely different from light at 3pm. Spatial proportions that look perfect on a 27-inch monitor feel cramped or cavernous when you are standing in the room. Use renders as communication aids with clients, not as proof that your design will work.
- ›Always include a note with AI renderings that says 'This visualisation shows proposed design direction. Actual space lighting and proportions may differ'
- ›Test your material selections in the actual client space under actual light before presenting the final scheme
- ›Keep a record of projects where your design looked different in reality than the render, and learn from the gaps
Protect the Thinking That Makes You Valuable
Clients perceive AI as a threat to your value when they see you spending most of your time prompt-writing and image-selecting rather than giving them design advice. The spatial reasoning you use to decide whether a room needs to feel intimate or expansive, or whether a natural material suits a client's lifestyle, is what they actually hired you for. ChatGPT and DALL-E should do the mechanical work of visualisation while you do the irreplaceable work of understanding the space and the person living in it.
- ›Talk clients through your design decisions out loud before you show them any render ('This corner needs a visual break, so I am placing a darker material here')
- ›When presenting renderings, explain the spatial thinking behind them, not just what the image shows
- ›Document your design process with sketches and notes so clients see the thinking, not just the AI output
Material Knowledge Cannot Be Automated
An AI image of a silk velvet sofa looks identical to one of a polyester blend, but the difference in how that sofa feels and behaves over five years is enormous. Your knowledge of how materials perform in real homes, which finishes scratch easily, and what textiles suit different clients' lifestyles is what separates you from someone who can prompt Midjourney. Use AI to visualise material combinations you have already chosen based on your knowledge, not to discover materials from images.
- ›Keep a physical sample library of materials you specify regularly, separate from any digital mood board
- ›When a client asks 'Can we use this material?' based on an AI render, explain your reasoning for using or avoiding it in their specific space
- ›Build your design concepts around material performance first, then use renderings to show how those materials look together
Client Relationships Built on Genuine Expertise
The interior designers who lose client loyalty to AI are those who let the AI become visible in the process. If your client thinks Midjourney created the design and you just selected the nicest image, they will question why they need you at all. Build your relationship by being the person in the room who understands the specific client's life, their actual daily routines, and what makes a space work for them personally. AI tools should be invisible in your process, not the centerpiece of it.
- ›Spend client meetings discussing how they actually live in their home, not reviewing AI images
- ›When you do use renderings, position them as 'tools I use to show you my ideas', not as the source of your ideas
- ›Keep your early design conversations in sketches and conversation, where the focus is on understanding their needs, not on visual outputs
Key principles
- 1.Your spatial thinking and material knowledge are what clients pay for, not your ability to generate images from text prompts.
- 2.Use AI to visualise design decisions you have already made, never to generate the decisions themselves.
- 3.Brief and design thinking must come before any mood board or rendering touches the project.
- 4.Protect the visibility of your expertise by making your reasoning clear to clients, so the AI stays a tool and not the solution.
- 5.Know the gaps between what AI renders show and what real spaces actually feel like, and design accordingly.
Key reminders
- Before opening Midjourney, write down the three most important spatial qualities this room needs to have for this specific client.
- Use hand sketches in early client meetings instead of AI images, so the conversation stays focused on understanding their needs.
- When presenting renderings, always explain the design decisions first, then show how the render illustrates those decisions.
- Keep a record of where your AI renderings diverged from reality and why, then use those learnings to brief renderings more carefully next time.
- Test material samples in the actual client space before you finalise any scheme, regardless of how good they looked in the AI render.
