A sunlit modern living room with a sage-green sofa, warm oak table and a large arched window.

Quick answer

Start with a wide photo of the room. Lock the walls, windows, doors and camera perspective, then describe one style direction, three materials and one lighting condition. Keep the result reviewable rather than photorealistically overstuffed.

Best for

  • Testing a palette before buying furniture
  • Creating mood images for a client review
  • Exploring a room’s layout and lighting direction
01

Preserve the architecture

Name what cannot move: wall positions, window shape, door openings, ceiling height, floor direction. If the model changes the architecture, the image stops being useful as a design reference. Put the architecture lock before the style instruction.

Use a wide, straight-on photo. A phone panorama can distort the room; a normal wide lens is easier to preserve. If the room is empty, the model has more freedom; if it is furnished, say which pieces stay.

02

Pick one style, three materials and a palette

“Modern interior” is too broad. Choose a lane: warm minimal, Japandi, mid-century, soft industrial. Then name three materials that carry the look: oak, travertine, linen; walnut, bouclé, brass; concrete, black steel, wool.

Limit the palette to two dominant colours and one accent. A sage-green sofa, warm oak and cream plaster is a coherent direction. Five colours and four materials produce a showroom collage, not a room.

03

Design the light with the room

Name the time of day and the direction of the light. Morning sun through an east window, late-afternoon side light, or a grey overcast day will each change the materials. Ask for realistic shadows and soft bounce.

If you are adding a lamp, say whether it is on. A warm floor lamp against cool daylight creates depth. A room lit by ten invisible sources looks flat and artificial.

04

Keep it reviewable, not just pretty

A useful concept shows the floor, the main seating, the circulation path and the window. Do not fill every surface with decor. Leave negative space so a client can imagine living there.

Check the perspective, the window mullions, the table legs, the rug edges and the relationship between furniture and walls. If the image is beautiful but spatially impossible, it cannot guide a purchase.

Soft Industrial Studio

A darker concept that still leaves the room readable.

Using the uploaded room as the architectural reference, create a soft industrial studio concept. Preserve the walls, windows, ceiling and perspective. Add a charcoal bouclé sofa, a black steel shelving unit, a concrete coffee table and a large abstract rug. Keep the palette to charcoal, warm grey and rust.

FAQ

  1. 1

    Can I redesign a room from a photo?

    Yes. Use image-to-image with a wide room photo. Lock the architecture and perspective, then change furniture, materials and lighting. Review the result for spatial accuracy before using it as a shopping reference.

  2. 2

    Is this a replacement for an interior designer?

    No. It is a concept and mood tool. It does not replace measurements, building codes, structural review or a designer’s site assessment. Use it to explore direction, not to approve construction.

  3. 3

    Which model is best for interiors?

    GPT Image 2 and FLUX 2 Pro are strong for material and lighting detail. SeeDream 5.0 Lite is a cheaper direction test, and Qwen Image Edit can handle simple furniture or background changes.

  4. 4

    Why does the room layout change?

    The model may prioritize the style over the architecture. Repeat the architecture lock, use a straight-on photo, and reduce the number of new furniture pieces in the prompt.

  5. 5

    Does interior generation use purchased credits?

    Yes. The hosted image workflow uses purchased credits and has no unlimited free tier. The pricing page shows the current packs and plans.
