Nano Banana: 5 Prompt Templates for Interior Design

Many designers and renovation creators want to turn sketches, empty rooms, or old photos into photorealistic renders without drawing or 3D modeling. Nano Banana can do that when nanobanana prompts are clear: swap materials, stage furniture, change style, switch perspective, and add annotations. This guide gives 5 reusable nanobanana 2 interior design templates and a 4-step formula.

1. Formula: 4 Steps to Control Output

Formula: [Role] + [Action] + [Visual details] + [Constraints]

Element	Example	Why
Role	You are an interior design visualizer…	Sets the task for the AI
Action	Replace / Stage / Render / Annotate	Clear verbs = better compliance
Details	Matte finishes, warm oak, indirect lighting	Material, color, light
Constraints	Strictly keep… / Do not alter layout	What must not change

Use Annotate for labels, Render for final renders, Stage for furniture placement, Replace for swapping elements.

2. Five High-Use Templates

Copy and replace the content in brackets [ ].

1. Local change / material swap

Prompt: You are an interior design visualizer. Change the [bed back wall] to [floral pattern wallpaper]. It is crucial to keep all other furniture, the bed, and the lighting exactly the same. Blend the new material realistically with the existing shadows.

2. Virtual staging (empty room)

Prompt: Stage this empty room as a [modern bedroom]. Add [a double bed, a rug, and a wardrobe]. Strictly maintain the existing architectural structure, windows, flooring, and perspective.

3. Style transfer (lock layout)

Prompt: Render a photorealistic 3D perspective view based strictly on the layout of this image. Apply a [warm, minimalist style]. Do not move walls or change furniture positions.

4. View change (top-down)

Prompt: Generate a direct top-down flat lay view of the scene. The subject is [a girl in a white hoodie]. Strictly maintain the character’s clothing and appearance. High angle, soft lighting.

5. Marketing annotation

Prompt: Annotate this image for a design presentation. Highlight the [bed] with a [soft glow effect] and add text labels for dimensions. Keep the photo unchanged, just overlay elements.

3. Four Pitfalls to Avoid

1. Verbs: Avoid Design, Create, Remodel; use Render, Stage, Visualize, Apply texture.
2. Semantic lock: Describe what to keep in detail (e.g. “small orange ginger tabby cat” not “the cat”).
3. Reference the image: Use “based on the attached image” or “relative to the reference.”
4. Iterate in chat: If something is wrong, say so in the next message instead of rewriting a long prompt.

4. Universal Local-Edit Formula

Action + Area + Detail + Constraint
Example: Change (action) the floor (area) to light oak (detail), keeping walls and furniture exactly as they are (constraint).
