9 Advanced Interior Design Techniques
Technique 1: Piece Multiple Furniture into One Space
Best For: Creating custom room layouts, combining furniture from different sources, client presentations
The Challenge:
You have photos of individual furniture pieces (sofa, chair, table, lamp) and want to see them all together in one room.
The Solution:
Upload multiple furniture images plus your base room image. Nano Banana understands spatial relationships and composes them naturally.
Click on the image to view the input images.

Let's remove the coffee table and the arm chair from the living room (image 1), and replace them using coffee table from image 2 and arm chair from image 3, keep the design details of these furnitures when placing them into the scene, and keep the rest of the scene in image 1 unchanged when creating the new image (use the same viewing angle and perspective)
Example Prompt:
Let's remove the coffee table and the arm chair from the living room (image 1), and replace them using coffee table from image 2 and arm chair from image 3, keep the design details of these furnitures when placing them into the scene, and keep the rest of the scene in image 1 unchanged when creating the new image (use the same viewing angle and perspective)
Pro Tips:
- Number your images clearly (image 1 = base room, image 2-4 = furniture)
- Specify placement: "sofa against the back wall," "coffee table in the center"
- Mention scale: "maintain realistic proportions"
- Request lighting consistency: "match the room's natural lighting"
Having 4-5 reference images might work in certain cases, but if you want to have a more accurate control, you should break them into multiple batches and modify the image in multiple steps. This allow the model to pay more attention to your instructions and details of the reference images.
Why This Works:
Nano Banana's multi-image composition excels at understanding spatial relationships and can intelligently place multiple objects while respecting perspective, scale, and lighting.
Best Model: Nano Banana (15-45s, advanced spatial reasoning)
Technique 2: Replace Specific Furniture from a Room
Best For: Testing furniture options, client revisions, before/after comparisons
The Challenge:
You want to replace just the sofa (or table, or chair) in a room without changing anything else.
The Solution:
Specify exactly which furniture piece to replace and describe the new one in detail.

Let's replace the white sofa on the right of the source image (image 1) with the red sofa from image 2 and place it about 45 degrees facing the window, and make sure you maintain the red sofa's design details when placing it in the scene, enhance the image quality and keep the rest unchanged.
Example Prompt:
Let's replace the white sofa on the right of the source image (image 1) with the red sofa from image 2 and place it about 45 degrees facing the window, and make sure you maintain the red sofa's design details when placing it in the scene, enhance the image quality and keep the rest unchanged.
Pro Tips:
- Be specific about what to keep: "keep everything else the same"
- Describe the replacement in detail: material, color, style, size
- Mention lighting: "match existing lighting and shadows"
- Specify scale: "ensure it fits the space naturally"
Best Model: Nano Banana (precise object replacement with context preservation)

Technique 3: Replace Textile/Fabrics in a Room
Best For: Testing fabric options, color coordination, material exploration
The Challenge:
You want to change curtains, cushions, throws, rugs, or upholstery fabrics without redesigning the entire room.
The Solution:
Specify which textiles to change and describe the new fabric, pattern, or color using either words or images.

Replace the white carpet under the sofa and coffee table from the image to a red woven style carpet. Keep the rest of the image unchanged.
Example: Change Curtain Fabric
Replace the white carpet under the sofa and coffee table from the image to a red woven style carpet. Keep the rest of the image unchanged.
Pro Tips:
- Specify fabric type: linen, velvet, bouclé, silk, cotton
- Mention texture: smooth, textured, woven, knitted
- Describe pattern: solid, striped, geometric, floral, vintage
- Consider light interaction: "show how light reflects on velvet"
Why This Works:
AI can isolate textile elements and apply new materials while preserving the underlying structure, lighting, and room context.
Best Model: Nano Banana (material accuracy and texture rendering)
Technique 4: Change Time of Day (Day to Night Transformation)
Best For: Showing lighting design, ambiance variations, real estate marketing
The Challenge:
You have a daytime photo but want to show how the space looks at night with interior lighting.
The Solution:
Describe the desired time of day and lighting conditions in detail.

Change the time of the photo from day time to 8pm in the evening, turn off the natural light coming into the room, turn on the interior's lightings, including the ceiling lamps to brighten up the room making it look like a cozy evening making the interior look bright.
Example: Day to Evening
Change the time of the photo from day time to 8pm in the evening, turn off the natural light coming into the room, turn on the interior's lightings, including the ceiling lamps to brighten up the room making it look like a cozy evening making the interior look bright.

Change the time of the photo from day time to 8pm in the evening, turn off the natural light coming into the room, turn on one of the ceiling lamps further in the distance to brighten up a corner of the room making it look like a cozy evening.
Example: Control of the Light
Change the time of the photo from day time to 8pm in the evening, turn off the natural light coming into the room, turn on one of the ceiling lamps further in the distance to brighten up a corner of the room making it look like a cozy evening.

Change this space to golden hour lighting (late afternoon). Show warm, soft sunlight streaming through windows at a low angle, creating long shadows and a warm golden glow on surfaces.
Example: Afternoon to Golden Hour
Change this space to golden hour lighting (late afternoon). Show warm, soft sunlight streaming through windows at a low angle, creating long shadows and a warm golden glow on surfaces.
Pro Tips:
- Specify which lights turn on: "table lamps, floor lamps, pendant lights"
- Describe the mood: "cozy," "intimate," "peaceful," "dramatic"
- Mention windows: "show evening sky outside" or "darker windows"
- Consider shadows: "soft shadows from lamps," "warm glow on walls"
Why This Works:
AI understands lighting principles and can realistically simulate how different times of day affect interior spaces, including light sources, shadows, and color temperature.
Best Model: Flux Pro (accurate lighting simulation)
Why Nano Banana isn't the best for this technique: Nano Banana is great for precision editing like shown in Precision Editing, but in the situation of changing lighting or time of day, this requires a total re-rendering of the image, as lights will affect every object in the scene, so Nano Banana's strength becomes its weakness.
Technique 5: CAD Drawing to Rendered Floor Plan
Best For: Architects, designers presenting to clients, real estate developers
The Challenge:
You have a CAD floor plan (line drawing) and need a photorealistic top-down rendered view with furniture and materials.
The Solution:
Upload your CAD drawing and describe the style, materials, and furnishings for each room.

Convert this CAD floor plan into a photorealistic top-down rendering. Living room: modern style with gray sofa, wooden coffee table, area rug. Kitchen: white cabinets, marble countertops, stainless appliances. Bedroom: Scandinavian style with light wood bed, white bedding. Show realistic materials, textures, and lighting from above. Use a consistent colour palette for the output image. keep all texts unchanged.

Best Model: Nano Banana (architectural understanding and spatial accuracy)
Technique 6: Rotate Viewing Angle in a Room
Best For: Virtual tours, showing different perspectives, comprehensive room documentation
The Challenge:
You have a photo of a room from one angle and want to see it from a different angle (e.g., from the opposite wall or from a corner).
The Solution:
Describe the new viewing angle and what should be visible from that perspective.

Rotate the camera view of this photo 45 degrees towards the window on the right side, still keep the coffee table in the center of the image. Make no change of the furniture layout
Example: Rotate 45 Degrees
Rotate the camera view of this photo 45 degrees towards the window on the right side, still keep the coffee table in the center of the image. Make no change of the furniture layout
Pro Tips:
- Describe current view: "currently showing sofa facing us"
- Specify new angle: "from opposite wall," "from corner," "45-degree rotation"
- Mention what should be visible: "show the TV wall," "include the doorway"
- Request consistency: "maintain same furniture and style"
- Consider perspective: "realistic human eye-level view"
Why This Works:
AI can understand spatial relationships and reconstruct rooms from different angles, though results work best when the original photo shows enough context.
Best Model: Flux Pro (Good with large porportion changes on the image)
Technique 7: Vibe Photos with Detail Variations
Best For: Social media content, design portfolios, showing design details
The Challenge:
You want to create multiple "vibe" shots focusing on different details of the same room (close-up of coffee table styling, corner reading nook, window view, etc.).
The Solution:
Generate variations that zoom into or highlight specific areas while maintaining the overall room aesthetic.

Create a close-up vibe photo of the coffee table in this living room. Focus on: the wooden table surface, styled with a ceramic vase with dried flowers, coffee table books, a candle, and a small plant. Show soft natural light, shallow depth of field, with the sofa blurred in the background. Cozy, intimate atmosphere.
Example: Coffee Table Styling Detail

Focus on: the wooden table surface, styled with a ceramic vase with dried flowers, coffee table books, a candle, and a small plant. Show soft natural light, shallow depth of field, with the sofa blurred in the background. Cozy, intimate atmosphere.
Example: Reading Nook Corner
Generate a detail shot of the reading corner in this room. Focus on: the armchair with textured throw blanket, side table with reading lamp and book, small plant, and window with natural light. Create a cozy, inviting vibe with warm lighting and intimate framing.
Example: Window View with Plants
Create a vibe photo focusing on the window area. Show: sheer curtains with soft natural light filtering through, potted plants on the windowsill, and a glimpse of the room's interior in soft focus. Peaceful, airy atmosphere.
Example: Texture Detail Shot
Generate a close-up detail photo showing textile textures: layered cushions on the sofa (velvet, linen, knit), throw blanket, and part of the wooden coffee table. Focus on textures and materials with soft, warm lighting. Tactile, cozy feel.
Pro Tips:
- Specify what to focus on: "coffee table," "reading corner," "window area"
- Describe composition: "close-up," "detail shot," "intimate framing"
- Mention depth of field: "blur background," "shallow focus"
- Include styling elements: books, plants, candles, textiles
- Describe mood: "cozy," "peaceful," "intimate," "warm"
Why This Works:
These detail shots are perfect for Instagram, Pinterest, or design portfolios, showing the thoughtful styling and atmosphere of a space.

Frequently Asked Questions
Which technique should I use for virtual staging?
Use Technique 1 (piece furniture together) or Technique 8 (remove existing furniture first, then add new).
Can I replace just the sofa fabric without changing the sofa shape?
Yes! Use Technique 3 (replace textiles) and specify "change upholstery fabric only, keep sofa shape and size."
How accurate is CAD to rendering?
Technique 5 produces realistic renderings but may interpret some details. Provide detailed descriptions for best results.
Can I rotate viewing angles for any room?
Technique 6 works best when the original photo shows enough context. Results may vary for very limited views. If you try with 180 degrees, you will obviously get unstable results as the majority of the content are only hullucinated by AI.
What's the difference between Technique 1 and 2?
Technique 1 adds multiple new furniture pieces to a room. Technique 2 replaces one existing piece with another which generally provides better result.
Is this suitable for professional client presentations?
Absolutely. All techniques produce high-quality, photorealistic results suitable for client presentations, proposals, and marketing materials. Use upsale to get it ready for presentation on large screens.
