AI and interior design: what it can do already, and what it still cannot

An interior designer in a European city spends 3 hours creating a moodboard for a client. She selects reference photos, browses furniture catalogues, combines colours in Photoshop and puts together a presentation that communicates the idea. The client looks at the moodboard, says "I like it but what if instead of Nordic we go Mediterranean?" and the designer starts again.

In 2026, the same designer uploads a photo of the client's living room to an AI tool, selects Mediterranean and has a photorealistic image of the redecorated living room in 30 seconds. The client says "and Nordic?" Another 30 seconds. "And what if we remove the cabinet at the back?" 30 seconds more.

AI has not replaced the designer. It has freed her from the hours of visual production so she can spend that time on what she really brings to the project: criterion, taste and the ability to understand what each client needs.

What AI does well in interior design today

Change the style of a space

The most direct application. You give the AI a photo of a room and ask it to transform it to another style. The result keeps the structure of the space (walls, windows, perspective) but changes furniture, colours, textiles and décor.

Works particularly well when:

• The space has good light and the photo is good quality
• The change is a full style switch (not fine adjustment)
• You do not need millimetric precision on the furniture dimensions

Does not work as well when:

• You need a specific piece from a specific catalogue
• The space has complex geometry (stairs, double heights, irregular ceilings)
• You want full control over each piece

Furnish empty spaces

You start from a photo of an empty room and the AI fills it with furniture coherent with the chosen style. It is the most widespread use in the property sector (virtual staging), but it also has direct application in interior design: showing the client how a space they just bought empty will look once furnished.

Turn sketches into photorealistic images

You draw a sketch by hand — at whatever level of detail you want — and the AI generates a photorealistic image of that space. It is not a technically precise 3D render, but for communicating an idea to the client and validating the project direction, it is more than enough.

This is especially valuable in the early phases of a project, when you are still exploring options and it makes no sense to invest in professional renders.

Improve portfolio photos

Correcting the lighting on a finished-project photo, removing elements that ruin the composition, adjusting colour balance. Operations that used to require Photoshop and time; now they take seconds.

What AI does not do well (yet)

Functional design

AI generates visually attractive images, but it does not understand how a space is lived in. It does not know that a sofa 30 cm from the wall makes the passage difficult. It does not calculate ergonomic distances. It does not verify that the furniture it proposes physically fits in the room.

Functional design — the layout that makes a space comfortable to live in — remains the job of the interior designer. AI proposes images. The designer designs liveable solutions.

Material specification and suppliers

When the AI generates a render with an "oak floor", it is a generic oak texture. It is not the Kahrs Oak Como 15mm model you are going to quote to the supplier. The connection between the generated image and the real catalogue of materials and manufacturers does not yet exist.

Some interior designers use the AI image as a visual reference and then manually search for the products that get closest to the result. It works, but it is not automatic.

Consistency between rooms

The AI generates each image independently. If you ask for the living room in Nordic style and then the bedroom in Nordic style, the result will be coherent in general style but not in detail: the wood tones may not match, the palette may shift slightly. For a full interior design project, where the whole flat needs visual coherence, you have to review and adjust.

Technical drawings and documentation

AI does not generate plans, sections, elevations or construction details. It does not replace AutoCAD, SketchUp or BIM modelling software. It is a visualisation tool, not a technical documentation tool.

How interior design studios are integrating AI

The studios that are getting the most out of these tools do not use them to replace their design process. They use them to accelerate the phases where visual production consumes the most time.

In the concept phase: Instead of searching reference photos on Pinterest and assembling moodboards, they generate images of the client's space directly in different styles. The client sees their own living room, not someone else's. The conversation shifts from "imagine something like this" to "this is what we propose."

In the presentation phase: Instead of waiting 5 days for the render artist to deliver the images, they generate concept renders with AI on the day of the meeting. If the client wants changes, they happen live. Iteration goes from weeks to minutes.

In the acquisition phase: A studio that includes 3–4 AI visualisations in its quote (cost: €10–20) is more likely to win the project than one that delivers a text-only quote. The image sells the project.

The interior designer who is not disappearing

There is a recurring narrative about AI "replacing" creative professionals. In interior design, that narrative does not hold up.

AI generates images. It does not understand why a layout works for a family with two children and a dog but not for a couple working from home. It does not know that the client has a €15,000 budget and that the floor it proposes costs €80 per square metre. It does not perceive that the afternoon light at that specific orientation makes warm tones work better than cool ones.

What AI does is remove the barrier between the idea the designer has in their head and the image the client needs to see to understand it. That barrier — which used to cost hours of visual production — now takes seconds to cross.

The interior designer who uses AI is not less professional. They are an interior designer who spends more time designing and less time producing presentations. And that, for the client, is strictly better.
