Prompt library
Ready prompts for interior visualisation, architectural presentation and spatial atmosphere.
Short answer
Three pieces of information decide an architectural prompt: the space's dimensions and ceiling height, the direction and time of day of the light, and the material list. If you must preserve a real space's geometry, a prompt is not enough; you need Stable Diffusion with ControlNet and a reference photograph.
The most common mistake in architectural and interior prompts is describing the space by style alone. Write "minimalist living room" and the model produces a room, but its dimensions, ceiling height and light conditions are arbitrary.
The prompts below carry dimension, light and material information. Keep those fixed and change the style description to suit your project.
Each prompt explains why it is written that way. Change the subject to suit you and leave the technical part as it is.
interior photograph of a living room with three metre ceilings, one tall window on the left wall, off-white lime plaster walls, light oak flooring, a low linen sofa, one large arched mirror, soft afternoon daylight raking in from the left, natural materials, no clutter, architectural photography, wide angle
Works well in these tools: flux, midjourney, stable-diffusion
Note: Stating the ceiling height in metres directly determines how the space's scale reads.
architectural visualisation of an empty apartment room, three metre ceiling, one large window on the left wall, matte white walls, light oak floor, no furniture at all, even natural daylight, neutral colours, wide angle from a corner, clean render aesthetic
Works well in these tools: flux, stable-diffusion
Note: Empty-space images give a base for testing furniture scenarios and convey a sense of scale to the client.
modern kitchen interior, handleless matte deep green cabinetry, honed pale marble worktop and splashback, brushed brass tapware, integrated lighting under the upper units, morning light from a window on the right, polished concrete floor, no clutter on the surfaces, architectural photography
Works well in these tools: flux, midjourney
Note: Naming materials individually (matte green, marble, brass) is the only way to control a space's material palette.
warm evening interior, living room lit only by three low table lamps and a fireplace, deep shadows in the corners, terracotta and charcoal palette, heavy textured curtains drawn, a worn leather armchair, film-like colour grade, quiet intimate mood, shot on 35mm
Works well in these tools: flux, midjourney
Note: Counting the light sources (three lamps and a fireplace) lets the model build a lighting logic, and the result is more convincing.
architectural exterior of a two storey concrete and timber house, large glazed openings, flat roof, surrounded by tall pines, overcast even daylight, muted natural palette, slight low angle, no people, no cars, clean architectural photography, sharp detail in the material joints
Works well in these tools: flux, midjourney, stable-diffusion
Note: "Overcast even daylight" is the preferred light in architectural presentation: it shows form clearly without shadow drama.
compact studio apartment interior, twenty square metres, two and a half metre ceiling, one window facing the camera, built-in storage along one wall, pale birch plywood, white walls, a folding table, bright even daylight, sense of openness despite small size, wide angle from the doorway
Works well in these tools: flux, stable-diffusion
Note: Giving the floor area in square metres helps the model build the space at a realistic scale.
interior of a small specialty coffee shop, exposed brick on one wall, dark stained timber counter, brass fittings, eight stools, warm pendant lighting above the counter, large street window on the right with soft daylight, worn concrete floor, no people, wide angle, warm inviting atmosphere
Works well in these tools: flux, midjourney
Note: Specifying the seat count (eight stools) is a practical way to control a space's scale through the prompt.
architectural detail photograph, the junction where a raw concrete wall meets oak flooring and a brass skirting strip, soft raking daylight from the left revealing surface texture, shallow depth of field, muted natural palette, macro detail, quiet composition
Works well in these tools: flux, midjourney, stable-diffusion
Note: Detail images are used in presentations to convey material quality, and they are far easier to generate than a full space.
A prompt alone is not enough. You need to photograph the room and use it as a depth or edge reference in Stable Diffusion's ControlNet; the model keeps walls, windows and ceiling height in place and changes only materials and furniture.
Because the prompt carries no dimensional information. State the ceiling height in metres, the floor area in square metres and the number of windows explicitly. Framing descriptions like "wide angle" also directly affect how the space reads.
You can, provided you say clearly what they are: design proposals, not renders that will be built literally. Also make sure every piece of furniture and material shown can actually be sourced — a client wanting furniture that does not exist is the most common problem in this field.
