Can an app design your home? An honest look at AI and interior design

You may have seen the comments popping up under designers’ posts lately. Why pay a designer when an app can do it for free? AI is coming for your job. Just upload a photo and it does the lot.

It’s a fair question, and it deserves a proper answer rather than a defensive one. So I’ll start by being completely upfront: I use AI in my own studio. You’ll find concept visuals on this very site that were made with the help of an image tool, and they’re labelled as such. So this isn’t a designer feeling threatened. It’s someone who uses these tools and knows exactly what they can and can’t do.

What AI does brilliantly

Let’s give credit where it’s due. AI image tools are fast, fun and endlessly patient. You can ask for your living room in sage green, then in terracotta, then in something entirely different, and have all three in a minute.

That makes them a wonderful way to discover what you’re drawn to. Plenty of people know they don’t like their room but can’t put their finger on what they would like instead. Playing with an app can help you find the words. And for seeing a mood or a direction before anything is settled, a quick visual is hard to beat. It’s exactly why I use them.

A picture of a room isn’t a plan for a room

Here’s the thing most people don’t realise until they try to use one. An AI image is built to look right. It isn’t built to work.

It doesn’t know your measurements

The app has no idea that your chimney breast is off centre, that the radiator sits right where the sofa wants to go, or that the door swings into the corner it has filled with a lovely armchair. It will happily draw a sofa that would never fit through your front door, and a dining table with no room left to pull out a chair.

The furniture often doesn’t exist

Look closely at a generated room and you’ll often find a lamp with no flex, a shelf held up by nothing at all, or a chair you can’t buy anywhere because it was invented a few seconds ago. It’s a beautiful picture of things that aren’t real. You can’t order an imaginary sideboard.

The light is always perfect

In an AI image the sun is forever pouring in, soft and golden. Your north-facing sitting room on a grey February afternoon is a different story. Light changes everything about a colour, which is why a paint that looks warm and creamy on screen can turn flat and grey on your actual walls. A designer plans for the light you have, not the light in the picture.

It doesn’t know your house

Every home has its quirks. The awkward alcove, the beam you keep hitting your head on, the lovely old floorboards you want to keep, the window that rattles in the wind. An app sees one photo from one angle. A designer asks about the rest, and the answers shape everything.

That’s also why online design works so well when it’s done properly. It isn’t one upload and a quick result. It’s photographs, measurements and a proper conversation, so the design is built around the room that’s really there. There’s more on how that works in What is eDesign?

It doesn’t know you

This is the big one. A room isn’t just a set of furniture. It’s how you live in it.

Do you have a dog who sleeps on the sofa? Children who build dens out of every cushion? Do you work from the kitchen table, host the whole family at Christmas, or read in the same chair every night? Do you need the room to feel calm after a long week, or full of life for friends?

An app can only answer the question you type. A good designer asks the questions you didn’t know to ask, and the answers become the brief. That’s where the real design happens, long before anyone chooses a cushion.

Taste is about knowing what to leave out

AI learns from millions of images and gives you something that looks like the most popular of them. That’s why so many generated rooms look strangely familiar. They’re an average of everyone else’s Instagram feed.

A home that feels like yours comes from editing, not adding. Knowing which piece to keep and which to let go. Making room for your grandmother’s chest of drawers, the painting you bought on holiday, the books you actually read. Those are the things that make a room feel like you, and no app knows they exist.

The real cost is getting it wrong

Free is lovely, until it isn’t. The most expensive part of doing up a room is rarely the design. It’s the mistakes.

A sofa that turns out to be too big for the room. A rug that leaves the furniture floating. A paint colour bought by the tin that looks nothing like it did on screen. Each one means return charges, wasted time, or simply living with something that never felt right, and those costs add up very quickly.

A designer’s real job is to get it right the first time. Measured layouts, named paint colours chosen for your light, and shopping lists of pieces that genuinely exist and genuinely fit. Seen that way, a design isn’t an extra cost. It’s what protects everything else you spend.

Someone who’s accountable

If an app gets it wrong, there’s no one to ask. It won’t explain why it chose that colour, won’t notice the rug is the wrong size, and won’t help when a piece sells out and you need an alternative that still works with everything else.

With a designer you have a person. Someone who explains the thinking, makes changes when something isn’t quite right, and answers your questions afterwards. Someone whose name is on the work.

How I use AI in the studio

So yes, technology plays a part here, and I think it should. It helps me work quickly and show you ideas sooner, so you can see a direction before anything is bought.

But the tool is the sketchbook, not the designer. Every design is led and approved by me: the layout, the measurements, the colours chosen for your light, and the real pieces you can actually buy. The decisions that make a room work are made by a person who has listened to you.

So, can AI replace an interior designer?

For inspiration, AI is a brilliant free starting point, and I’d encourage you to use it. For a room you’ll live in every day for years, it isn’t enough on its own. Online recipes didn’t replace good cooks, and a calculator never replaced a good accountant. Tools make good people faster. They don’t replace knowing what you’re doing.

How to make the most of both

If you enjoy playing with AI, here’s how to put it to good use. Save every image that makes you stop and look twice. After a while, notice what keeps coming up. Perhaps it’s warm whites, or old wood, or a particular shade of green. Those patterns are your taste, showing itself.

Then bring them to a designer. Saved images make one of the best briefs there is, because they show what words often can’t. My job is to turn them into a room that fits your space, your light, your budget and your life.

If you’d like a room that really works

Sunday Ambience designs entirely online, from your photographs and a few measurements, with every design led and approved by me.

The Signature Interior Design package is £1,495 for one room, designed in real depth, with photorealistic visuals and a live concept call. If you’d prefer to begin more gently, Room Ambience is the lighter option at £495.

Or simply send me a few photographs, and the AI images you’ve fallen for if you have them, and tell me what isn’t quite working. I read every message myself, and there’s no obligation of any kind.
