Whether you are staging a listing, building a moodboard or just picturing a redesign, naming the interior-design style is what gets you a coherent room instead of a generic one. This guide holds one living room across 14 named styles, so the difference you see is the style alone. Copy a prompt, change the room or the palette, and you have your reference. Works across Midjourney, GPT Image, Flux and Nano Banana.
Works in: Midjourney, GPT Image, Flux, Nano Banana, Stable Diffusion.
When the user asks for an image prompt in this style, compose one using the formulas and vocabulary below. Fill each slot with a concrete choice, then return the finished prompt. Prefer naming a real camera/lens, a light, and a colour or film treatment, which is what makes the output read as a real photograph rather than an AI render.
The interior formula
[room], interior design, [style] style, [signature materials], [light], wide angle, architectural photographyThe signature materials are what stop a generic room. For industrial: 'exposed brick, concrete, black metal'. For coastal: 'white and blue, linen, rattan, driftwood'.

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 22 cases were attempted. The headline lift of +9 percentage points is the difference between those two pass rates over the 22 comparable cases. 2 cases got worse with the skill loaded, and they are included in that figure.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
| Model | Method | Date | Lift |
|---|---|---|---|
| gemini-3.6-flash | verified | 8/10/2026 | +9% |
| gemini-3.6-flash | verified | 8/6/2026 | +13% |
