Interior Design Prompts: Room Visualization

Interior design is about more than just furniture; it's about Atmosphere. Nano Banana can visualize complex room layouts, lighting schemes, and material combinations, helping you "try before you buy" for home renovations.

Understanding Interior Rendering

To get a photorealistic room, you need to define the Architectural Shell (windows, floors, walls) separately from the Decor (furniture, rugs, art). If you mix them up, the AI gets confused about scale.

SCANDINAVIAN LIVING ROOM

Let's start with the foundation example from the Product Visualization overview. Here is the complete, fully detailed prompt to generate the "SCANDINAVIAN LIVING ROOM".

[Optional Base Image] Design a photorealistic living room interior.

Architecture:
- **Style**: Modern Scandinavian
- **Windows**: Large floor-to-ceiling windows with sheer white curtains
- **Flooring**: Light oak herringbone parquet
- **Walls**: Soft off-white matte paint

Furniture & Decor:
- **Sofa**: Low-profile beige linen sectional
- **Coffee Table**: Organic shape glass and wood table
- **Rug**: Textured wool Berber rug
- **Accents**: Potted fiddle leaf fig, abstract line art print

Lighting & Atmosphere:
- **Light Source**: Soft morning sunlight streaming in (volumetric)
- **Shadows**: Long, soft shadows
- **Vibe**: Airy, peaceful, minimalist, cozy (hygge)

Why This Works

The "Herringbone Parquet": Specific architectural details like "herringbone" or "wide plank" give the room structure and scale. Without them, floors look like flat color blocks.

The "Volumetric" Light: "Volumetric lighting" (or "god rays") adds dust and atmosphere to the air, making the empty space feel real and lived-in.

The "Linen" and "Wool": Mixing textures is key to Scandinavian design. Specifying "linen" vs. "wool" prevents the room from looking sterile or plastic.

Common Mistakes

Note:

Impossible Architecture: AI loves to put windows where they don't belong (like on a ceiling). Use "skylight" or "window on left wall" to constrain the architecture if it gets weird.
