AI in Interior Design: What It Does and What It Cannot
Nicholas Kaiko - Owner and design principal - Kaiko Design Interiors
The interior design profession has changed more in the past decade than in several before it. Software that once took days to render now returns an image in seconds. A rough brief can become a wall of visual options before the first meeting is over. Artificial intelligence sits at the centre of that shift, and at Kaiko Design, a Sydney interior design studio, we treat it as what it is: a genuinely useful tool, and nothing more than a tool.
This article looks at how AI is actually used in interior design today, what it does well, why it will not replace the designer, and where the technology appears to be heading. The honest version, not the marketing one.
How AI Is Actually Used in Interior Design
Most of the real value of AI in design sits early in the process, at the point of ideation. A designer can describe a room, a mood, a palette or a material direction, and generate a spread of visual options in minutes. It is a way of thinking out loud with pictures. The rough concept that used to live in a sketchbook can now be tested in a dozen directions before anyone commits to one.
The other genuinely useful applications are visualisation and space planning. Tools now exist that turn a plain massing model or a basic plan into presentation-quality imagery, which shortens the distance between a technical drawing and something a client can actually read. Some systems help test layouts against the constraints of a room. Others suggest colour and material combinations based on patterns learned across thousands of interiors.
The skill in all of this is the prompt. Directing AI well is closer to briefing a junior than pressing a button. A vague instruction returns generic output. A precise one, informed by an actual point of view about proportion, light and palette, returns something worth looking at. The tool is only ever as good as the judgement steering it.
What AI Does Well
Speed is the obvious gain, but it is not the most interesting one. The more valuable quality is breadth. AI will happily produce twenty variations on an idea, including several a designer might not have reached quickly on their own. Occasionally one of those unexpected combinations is genuinely useful, a starting point that sharpens the thinking even when the image itself is discarded.
Used this way, AI widens creative exploration rather than replacing it. It lowers the cost of asking "what if" and lets more of those questions be answered visually and early. For a client, that means faster, richer conversations about direction, and fewer surprises later. The benefit is a better process and a better outcome, not a cheaper one.
What AI does not do is decide. It generates. Every option it returns still has to be read, judged, kept or rejected by someone who understands why one works and another does not.
Why AI Will Not Replace Designers
The parts of interior design that matter most are precisely the parts AI cannot do.
Colour is the clearest example. A convincing render of a scheme is not the same as knowing how a particular green will behave in a north-facing room at four in the afternoon, or how it will sit against an existing floor, or what it will do to the people who live with it. That is a human skill, built over years, and it is the heart of colour in interior design as we practise it.
The same is true of spatial and material judgement. Whether a joinery detail is worth the cost, whether a stone will wear well in a family kitchen, whether a room actually functions for the way a household lives, these are decisions grounded in experience, not pattern-matching.
Then there is the client. Good design begins with understanding people, their habits, their tolerance for risk, the things they will not say in the first meeting. That understanding is relational, and it is the foundation of the Kaiko Design approach to every project.
Finally, and least glamorously, there is documentation. A design only becomes a home when it can be built. The drawings, schedules and specifications that make that possible, and the interior design project management that holds it all together on site, remain firmly human work. AI can help present an idea. It cannot yet take responsibility for making it real.
How Our Studio Uses AI
We are candid about this. AI is part of our toolkit, and this very journal is AI-assisted in its production. We see no reason to pretend otherwise. What matters is where the line sits.
The line is judgement. We use AI to explore, to visualise and to move faster through the early stages of thinking. We do not outsource the decisions. The colour-led sensibility, the material choices, the detailing and the accountability for the finished result stay with the people in the studio. That is true of every piece of bespoke residential interior design we take on, and it is why our fixed-fee pricing buys expertise and considered judgement rather than volume of output.
A good tool used by a skilled hand produces better work. The same tool without the hand produces noise. We know which side of that we are on.
Where This Is Heading
The technology will keep improving, and quickly. Visualisation will get sharper, space planning more capable, the gap between concept and image narrower still. That is welcome. Anything that removes friction from exploration and helps a client see an idea sooner is worth having.
But the direction of travel does not change the fundamentals. Design intelligence, taste, spatial judgement and the trust between a designer and a client will remain human for a long time yet. The studios that do well with AI will be the ones that treat it as an instrument, played by someone who knows what they are doing.
If you are planning a full renovation or a new build and want that judgement behind it, you are welcome to talk to the studio about your project.
