Short answer: Describe the style by its materials and furniture, not just its name: "pale oak floor, a low linen sofa in warm off-white, a round light wood coffee table" says more than "Scandinavian". Then give the camera position ("from a standing position across the room, walls and verticals kept perfectly vertical"), the light ("soft diffused daylight"), three colours and "uncluttered". To redesign your own room, attach its photo and say what must stay: walls, windows, doors and floor.
"A cosy living room" gives you a generic showroom with too many cushions. Interior photographs look real because of a few specific things: real materials, straight walls, one kind of light and a short palette. Put those in the prompt and the room looks like a page from a design magazine instead of a furniture catalogue.
How do you describe an interior style?
By the things in it. The style's name is a starting point; the materials do the work:
| Style | Words that make it |
|---|---|
| Scandinavian | Pale oak floor, linen sofa, light wood, sheer curtains, one plant, cream and sage |
| Japandi | Low oak platform bed, rumpled linen, round paper pendant lamp, slatted wood wall, beige, clay and charcoal |
| Dark academia library | Forest-green walls, floor-to-ceiling dark wood shelves, cognac leather armchair, brass floor lamp |
| Bright kitchen | White zellige tiles, open wood shelf, trailing plants, butcher block counter, morning sun |
Two more lines matter in every prompt: "walls and verticals kept perfectly vertical" (otherwise the model tilts them, like a phone photo taken from above) and "uncluttered" (otherwise it fills every surface).

How do you redesign a photo of your own room?
Attach the photo and split the prompt in two: what stays and what changes. For example: "Redesign the room in the reference photo. Keep the walls, windows, doors, ceiling and floor plan exactly as they are, with the same camera position. Change the furniture, colours and decor to a Japandi style: a low oak bed, sand-coloured linen, a round paper pendant lamp, beige, clay and charcoal." Without the first half, models often move a window or invent a wall.
Then treat the result as a mood picture, not a plan. The model does not know your room's measurements, so a sofa that looks right in the picture may not fit through the door. Change one thing per round ("now make the walls sage green") rather than asking for everything at once, so you can see what each change does.
Why ask for no readable text?
Book spines, framed posters and jar labels come back as half-letters that make a photo look fake at a glance. The library prompt's "books whose spines show only colour and texture" keeps the shelves full without a single wrong word.
