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.

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.

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.

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.

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.

Key principles

  1. 1.Your spatial thinking and material knowledge are what clients pay for, not your ability to generate images from text prompts.
  2. 2.Use AI to visualise design decisions you have already made, never to generate the decisions themselves.
  3. 3.Brief and design thinking must come before any mood board or rendering touches the project.
  4. 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. 5.Know the gaps between what AI renders show and what real spaces actually feel like, and design accordingly.
