Interior Design Styles Guide: Visualize Your Dream Space with AI

The Problem: Choosing an interior design style is overwhelming. You're unsure if Boho, Japandi, or Modern Minimalist will work in your space, and you don't want to commit to expensive furniture or paint without seeing the result first.

The Solution: Use AI to visualize any interior style instantly. Generate photorealistic room designs, test different aesthetics, and see your vision before making physical changes.

What this article is going to cover:

• Part 1: 3 ways to generate styled interiors (from scratch, from sketches, with reference images)
• Part 2: 5 styling techniques (wall colors, lighting, seasonal variations, style mixing, decluttering)

We will be primarily using Nano Banana and Midjourney for the examples in this article. Both can be accessed from the Prompt Composer on the side of the page if you want to try it out.

For advanced techniques like furniture replacement, CAD rendering, and material swaps, see our Advanced Interior Design Techniques Guide.

Part 1: Three Ways to Generate Styled Interiors

Method 1: Text-to-Image Style Generation (From Scratch)

Best For: Creating inspiration boards, exploring different styles, generating concepts from imagination

Best Model: MidJourney (fast, creative, excellent for pure text-to-image)

How It Works:
Describe your desired interior style in detail, and AI generates a photorealistic room from scratch. No input images needed.

Example: Japandi Living Room

A Japandi living room with a low wooden coffee table, beige linen sofa, natural oak flooring, paper pendant lamp, minimal decor, soft natural light through sheer curtains, muted sage green accent wall, warm and calm atmosphere

More Style Examples to Try:

Boho Bedroom:

A boho bedroom with macramé wall hanging, layered Persian rugs, terracotta and mustard cushions, hanging pothos plants, rattan furniture, warm string lights, textured throws, vintage mirror, eclectic and cozy

Modern Minimalist Kitchen:

A minimalist kitchen with handleless white cabinets, black countertops, stainless steel appliances, pendant lights, no visible clutter, clean lines, monochromatic color scheme, polished concrete floor

Coastal Living Room:

A coastal living room with white slipcovered sofa, navy and white striped pillows, driftwood coffee table, jute rug, sheer white curtains, rope accents, seafoam green throw, natural light, breezy atmosphere

Industrial Loft:

An industrial loft with exposed red brick walls, concrete floors, black metal beams, leather sofa, reclaimed wood coffee table, Edison bulb pendant lights, metal shelving, vintage factory windows, urban and raw

Prompting Tips for Text-to-Image:

• Be specific about materials (wood, linen, marble, concrete)
• Mention lighting (natural light, warm lighting, soft glow)
• Include mood words (cozy, airy, minimalist, eclectic)
• Specify colors and textures

If you are unsure, you can always paste these examples into Chatgpt or Claude to generate your own.

Method 2: Style Empty Rooms or Sketches

Best For: Real estate staging, architectural visualization, turning concepts into reality

Best Model: Nano Banana (advanced spatial reasoning, accurate furniture placement)

How It Works:
Upload a photo of an empty room or a hand-drawn sketch, then describe the style and furnishings you want. Nano Banana understands spatial relationships and places furniture realistically. Click on the below image to view the input image of the empty room.

Example: Empty Room → Japandi Living Room

Transform this empty room into a fully furnished Japandi living room with a beige linen sofa, low wooden coffee table, floor lamp, area rug, wall art, potted plants, and warm natural lighting. Keep the same perspective and camera angle. respect the current layout, place furnitures in reasonable places.

More Examples to Try:

Empty Bedroom → Scandinavian Style:

Furnish this empty bedroom in Scandinavian style with a light wood platform bed, white bedding, gray knit throw, simple nightstands, pendant lamp, potted plant, and soft natural light from the window. respect the current layout, place furnitures in reasonable places.

Sketch → Modern Kitchen:

Convert this hand-drawn kitchen sketch into a photorealistic rendering with modern minimalist style. Include white handleless cabinets, black countertops, stainless steel appliances, and pendant lights. respect the current layout, place furnitures in reasonable places.

Raw Construction Space → Boho Cafe:

Transform this raw construction space into a boho cafe with colorful seating, hanging plants, wooden tables, macramé decorations, warm string lights, and a cozy eclectic atmosphere. respect the current layout, place furnitures in reasonable places.

Empty Office → Industrial Workspace:

Style this empty office as an industrial workspace with metal desks, exposed brick accent wall, concrete floors, vintage chairs, Edison bulb lighting, and open shelving. respect the current layout, place furnitures in reasonable places.

Why Nano Banana Excels Here:

• Understands perspective and scale
• Places furniture realistically (no floating objects)
• Maintains lighting consistency
• Respects architectural features (windows, doors, beams)

Notice in the examples above, the furnitures are placed in reasonable places without blocking the doors, and also both the lighting from the window and the lamp are affecting the furnitures.

Method 3: Use Reference Images to Guide Styling

Best For: Combining elements you love, applying specific furniture/decor to your space, style transfer

Best Model: Nano Banana (multi-image understanding and composition)

How It Works:
Upload your room photo plus 1-3 reference images showing the style, furniture, or mood you want. Nano Banana extracts elements from references and applies them to your space.

Example: Apply Reference Style to Your Room

Fill image 1's empty space with furnitures and decoration items extracted from reference image 2(chairs/sofa/shelves etc)

More Reference-Based Examples:

Copy Furniture from Pinterest:

Transform this bedroom to match the style in image 2. Use the same bed frame, nightstands, lighting, and color scheme. Keep my room's window placement and dimensions

Apply Mood from Magazine:

Restyle this dining room with the warm, cozy atmosphere from image 2. Use similar wood tones, textile textures, and lighting mood while keeping the table position

Combine Multiple References:

Create a living room that combines: the sofa style from image 2, the lighting fixtures from image 3, and the color palette from image 4. Set it in my current space shown in the main image

Why This Method Works:

• An image is better than 1000 words
• Show exactly what you want with images
• Mix and match elements from different sources
• Maintain your room's actual layout

Part 2: Styling Techniques for Interior Design

Now that you know how to generate styled interiors, here are 5 practical styling techniques to refine and perfect your designs.

Technique 1: Test Different Wall Colors and Materials

The Challenge:
You want to see how different wall colors or materials (paint, wallpaper, wood paneling, tiles) would look before committing.

The Solution:
Upload your room photo and specify the wall treatment you want to test.

Example: Change Wall Color

Change the wall color in this living room to sage green. Keep all furniture, lighting, and decor exactly the same.

Example: Add Wood Paneling

Replace the painted walls with vertical wood paneling in natural oak. Maintain the same furniture and layout.

Example: Test Wallpaper

Apply a subtle geometric wallpaper pattern in soft gray tones to the accent wall behind the sofa. Keep everything else unchanged.

Why This Works:
AI can isolate walls and apply new colors or textures while preserving lighting, shadows, and the rest of the scene.

Best Model: Nano Banana (precise area editing) or Flux (fast iterations for color testing)

Pro Tip: Test multiple colors quickly by generating several variations with different prompts.

Technique 2: Adjust Lighting and Time of Day

The Challenge:
You want to see how a space looks in different lighting conditions (morning light, evening, golden hour, overcast).

The Solution:
Specify the lighting mood and time of day in your prompt. Note that the input image will also affect the final result, in the following example, there is only one lamp in the room with no ceiling light in the original image, so the final result will not be a brightly lit room.

Example: Evening Ambiance

Change the time of the photo from day time to 8pm in the evening, turn off the natural light coming through the windows making it look like night time. turn on the lamp to brighten up the room making it look like a cozy evening making the interior look bright.

Example: Morning Light

Transform this bedroom to show bright morning sunlight streaming through the windows, creating a fresh and energizing atmosphere.

Example: Moody Overcast

Show this space on an overcast day with soft, diffused natural light and a calm, contemplative mood.

Why This Works:
Lighting dramatically affects how colors and materials appear. Testing different conditions helps you make better design decisions and understand how the space feels throughout the day.

Best Model: Flux Pro (fast lighting variations) or Nano Banana (more accurate lighting changes on top of the Flux output)

For advanced interior lighting controls, see our Advanced Interior Design Techniques Guide.

Technique 3: Seasonal Styling and Decor Variations

The Challenge:
You want to see how a space can be styled for different seasons or occasions.

The Solution:
Describe the seasonal elements and mood you want to add.

Example: Winter Cozy

Transform this living room for winter with cozy blankets, warm throws, candles, a knit pouf, and warm ambient lighting. Add a sense of hygge and warmth.

Example: Summer Bright

Style this sunroom for summer with light linen curtains, bright cushions, fresh flowers, and an airy, breezy atmosphere. Show bright natural daylight.

Example: Holiday Decor

Add subtle holiday decorations to this living room: a small Christmas tree, garland on the mantle, warm string lights, and festive pillows. Keep it elegant and not overwhelming.

Why This Works:
Seasonal styling helps you visualize how versatile a space can be and how simple decor changes can transform the mood.

Best Model: Nano Banana (accurate seasonal changes and decor placement)

Technique 4: Mix and Match Styles (Eclectic Design)

The Challenge:
You want to blend elements from different styles (e.g., Scandinavian + Boho, Modern + Industrial).

The Solution:
Describe the specific elements from each style you want to combine.

Example: Scandi-Boho

Create a living room that blends Scandinavian and Boho styles: light wood furniture and neutral base (Scandi) with layered textiles, colorful cushions, and hanging plants (Boho). Balance minimalism with warmth.

Example: Modern Industrial

Design a bedroom mixing modern minimalist and industrial elements: clean white walls and simple furniture (modern) with exposed brick accent wall, metal light fixtures, and concrete textures (industrial).

Example: Coastal Japandi

Combine coastal and Japandi styles in this space: natural wood and neutral tones (Japandi) with light blues, linen textures, and breezy atmosphere (coastal). Keep it calm and organic.

Why This Works:
Many beautiful interiors blend multiple styles. AI can help you visualize these combinations and find the right balance.

Best Model: Text to image with MidJourney (creative style blending) then make specific edits with Nano Banana (accurate execution)

Technique 5: Declutter and Simplify Existing Spaces

The Challenge:
Your space feels cluttered or overwhelming, and you want to see it simplified and organized.

The Solution:
Ask AI to remove clutter, simplify decor, and create a cleaner version of your space.

Example: Simplify Bedroom

Simplify this bedroom by removing excess decor, clutter, items on the floor, and unnecessary furniture. Keep only essential pieces. Clean up the room and create a clean, breathable space.

Example: Organize Workspace

Clean up this home office by organizing books on shelves, removing clutter from the desk, and creating a minimalist, productive workspace. Keep it functional but uncluttered.

Example: Neutralize for Listing

Prepare this bedroom for a real estate listing by removing personal items, simplifying decor, and creating a neutral, appealing space that buyers can envision themselves in.

Why This Works:
Perfect for real estate agents, homeowners preparing to sell, or anyone wanting to see their space with less visual noise.
