A good interior prompt is not a poem. It is a specification: material, colour, light, and mood, in that order. Architectural AI keeps your walls, windows and camera fixed, so everything you write is spent describing surfaces and atmosphere rather than the room itself.
The prompts below are structured that way. Each one names concrete materials (oak, travertine, bouclé, brushed brass) instead of vague adjectives, because material names are what actually move the output. Paste one, change the two or three words that matter for your project, and generate.

Specific materials, a defined light condition and a short list of hero objects. Naming a real material ("honed travertine", "white oak", "bouclé") changes the output far more than adjectives like "beautiful" or "luxurious". Because architectural AI preserves your room geometry, you never need to describe the room shape itself.
No. When you upload a photo of the room, the camera, framing and proportions are already fixed by that image. Spend the prompt on materials, colour and light instead.
They will produce attractive images, but Midjourney invents its own room. Architectural AI applies the same description to your actual space, which is what you need when the render has to represent a real project.
One to two sentences is usually enough — roughly 15 to 30 words of concrete detail. Longer prompts start contradicting themselves and the result gets muddier, not richer.
