Prompt: Generate an Interior Design Concept

Generates one photorealistic interior concept render for a specific room, with layout, materials and lighting specified before generation.

The prompt

Open in Studio

Generate ONE interior design concept image with the following exact specification.

Room: {{ROOM TYPE — e.g. a small living room, approximately 4m x 5m}}.

Design style: {{DESIGN STYLE — e.g. warm Scandinavian minimalism}}.

Key furniture and layout: {{LAYOUT — e.g. a low sofa against the left wall, a round wooden coffee table centred, a floor lamp in the far right corner}}.

Materials and palette: {{MATERIALS AND PALETTE — e.g. light oak flooring, off-white walls, muted sage textiles}}.

Lighting: {{LIGHTING — e.g. soft natural daylight from a large window on the right, warm supplementary lamp light}}.

Constraints:
- Photorealistic render, eye-level camera angle, as if photographed for a real estate or interior design listing
- Keep every item of furniture and its position consistent with the layout given; do not add furniture that wasn't specified
- No people, pets or visible brand names/logos anywhere in the image
- Walls, floor and visible structural elements must remain consistent with the room type and materials given, with no conflicting materials introduced

Example: "a low sofa against the left wall" is specific enough to place directly; "some nice furniture" is not.

Return only the generated image, with no accompanying text or caption.

Before generating, check the layout, materials and lighting above don't conflict (e.g. a window position that would put light on the wrong wall for the lighting described).

Example

Input

ROOM TYPE — e.g. a small living room, approximately 4m x 5m: a small living room, approximately 4m x 5m
DESIGN STYLE — e.g. warm Scandinavian minimalism: warm Scandinavian minimalism
LAYOUT — e.g. a low sofa against the left wall, a round wooden coffee table centred, a floor lamp in the far right corner: a low sofa against the left wall, a round wooden coffee table centred, a floor lamp in the far right corner
MATERIALS AND PALETTE — e.g. light oak flooring, off-white walls, muted sage textiles: light oak flooring, off-white walls, muted sage textiles
LIGHTING — e.g. soft natural daylight from a large window on the right, warm supplementary lamp light: soft natural daylight from a large window on the right, warm supplementary lamp light

Output (a written description, not a generated image)

What a good result should look like: A photorealistic, eye-level render of a small living room styled in warm Scandinavian minimalism. A low, sage-green upholstered sofa sits against the left wall, with a round light-oak coffee table centred in front of it on matching oak flooring. A slim floor lamp with a warm-toned shade stands in the far right corner. The walls are off-white and unadorned, keeping the palette calm and consistent with the light oak and muted sage materials specified. Soft natural daylight enters from a large window on the right, catching the sofa's texture and casting gentle shadows across the floor, supplemented by a warm glow from the floor lamp. No people, pets, brand names or logos appear anywhere in the image, and no furniture beyond the sofa, table and lamp appears in the scene.

Why it works

Fixing the exact furniture layout stops the model rearranging or substituting pieces between generations, which matters when comparing design options.
Specifying lighting direction alongside window position controls whether the render looks physically plausible instead of subtly inconsistent.
The pre-generation consistency check catches a conflicting light source and window placement before it produces an implausible render.

Why the basic version fails

“Design a living room in a Scandinavian style” leaves the furniture layout, materials and lighting entirely up to the model, so you get a plausible-looking room that has nothing to do with your actual space or plan, and often a different, incompatible layout every time you regenerate it.

What this prompt fixes

Fixing the furniture positions and materials means the render reflects an actual proposed layout you can evaluate, not a random showroom scene. Specifying the light source’s direction alongside the room’s real window position is what keeps the render physically consistent instead of showing shadows that fall the wrong way, which is a common giveaway of an ungrounded AI render.

Tips per model

Gemini handles specific furniture placement well when each item’s position is stated individually rather than as a general “furnished nicely” instruction.
ChatGPT’s image generation keeps material palettes more consistent across a room when the palette is named explicitly rather than implied by the style alone.
Generate a few variations with only the camera angle changed once the layout is right — it’s a faster way to review a design than changing several fields between attempts.
