The Most Popular Interior Design Styles of 2026

In this article, RED has carefully curated and organized 21 of the most widely loved interior design styles, making it easier for you to find the perfect match for your home or workspace.

I. Minimalist & Modern Interior Design Styles: Where Function Comes First

1. Minimalism: Purposeful Simplicity

Minimalism is not simply about owning fewer things, it is a design philosophy centered on intentional simplicity. In minimalist interiors, every piece of furniture has a clear purpose: it either serves a functional need or contributes aesthetic value.

Minimalist spaces feel light, open, and calming, allowing people to focus on how they live rather than being overwhelmed by visual clutter. This style encourages a sense of clarity and mindfulness in everyday life.

At RED, we approach minimalism by first understanding the homeowner’s daily routines and practical needs. Only after that do we determine the color palette, materials, and spatial layout. A well-executed minimalist space never feels cold or empty. When lighting, textures, and proportions are handled thoughtfully, minimalism can feel surprisingly warm and inviting.

How to apply the Minimalist style effectively:

• Keep the color palette limited, ideally 2–3 tones such as white, gray, beige, or white paired with light wood
• Choose furniture with clean lines and integrated forms; avoid excessive decorative details
• Maximize natural light with large glass windows and sheer curtains
• Reduce decorative items and instead focus on 1–2 meaningful focal points (abstract artwork, designer lighting)
• Use built-in storage systems to conceal clutter and maintain visual simplicity

RED project examples:

• A 65m2 apartment designed in a minimalist style, featuring flat-panel kitchen cabinets with concealed handles, light wood veneer, and white stone surfaces → compact yet airy and open
• A bedroom furnished only with a low-profile bed, simple bedside tables, and pendant lights → calm, restful, and ideal for sleep

2. Modern Style: Practical, Flexible, and Urban

Among today’s most popular interior design styles, Modern design stands out for its adaptability and suitability for urban living. Unlike Minimalism, Modern interiors are less strict about reducing items and instead emphasize functionality, comfort, and smart spatial planning.

The Modern style favors clear geometric forms, smooth surfaces, and a mix of industrial materials such as glass, metal, engineered stone, and wood. The result is a clean, energetic space that works well across different housing types and lifestyles.

Key principles for Modern interior design:

• Select multifunctional furniture: sofa beds, extendable dining tables, storage beds
• Use neutral tones as a base (white, gray, beige), then add 1–2 bold accent colors
• Embrace open-plan layouts that connect the kitchen, dining, and living areas
• Balance natural daylight with artificial lighting (downlights, concealed ceiling lights)
• Choose durable, low-maintenance materials suitable for daily use

Application examples:

• A three-story townhouse designed in a modern style, featuring a double-height living room and glass staircase → enhanced brightness and a sense of spaciousness
• A young family apartment using an L-shaped sofa, minimalist coffee table, and wall-mounted TV cabinet → optimized floor area and everyday convenience

3. Contemporary Style: Design That Evolves with the Times

Contemporary design is often confused with Modern style, but in reality, it reflects what is current and trending at any given moment. Rather than following a fixed set of rules, Contemporary interiors evolve alongside new ideas, materials, and technologies in design.

This style allows designers the freedom to mix materials, forms, and colors, as long as the overall space remains refined and visually balanced. Among today’s interior design styles, Contemporary is an ideal choice for those who enjoy freshness and innovation without venturing into overly bold or experimental territory.

Contemporary spaces tend to feel light and open, with minimal visual noise and a strong emphasis on lighting to enhance mood and spatial depth.

Key approaches to Contemporary interior design:

• Use simple forms with subtle focal points, such as soft curves or accent walls
• Combine modern materials like stone, glass, matte-finished metal, and finely treated wood
• Avoid classical patterns; favor smooth surfaces or gentle textures instead
• Prioritize lighting with large windows, concealed light strips, and streamlined decorative fixtures
• Choose artistic décor pieces, but keep quantities restrained

Real-world examples:

• A luxury apartment living room featuring a neutral-toned sofa, natural stone coffee table, and a one-of-a-kind pendant light
• A Contemporary bedroom with an upholstered headboard wall and indirect lighting → elegant yet understated

4. Hi-Tech Style: A Vision of the Future

Hi-Tech represents the most forward-looking direction within modern interior design styles. This approach is built on the seamless integration of design, technology, and user experience.

Every element in a Hi-Tech space is carefully considered to deliver maximum comfort, intelligent functionality, and a strong visual impact. The aesthetic often leans toward an industrial feel, characterized by cool color palettes, glossy surfaces, and smart systems deeply embedded into the architecture.

Core principles of Hi-Tech interior design:

• Prioritize smart furniture and systems: motion-sensor lighting, automated curtains, centralized control systems
• Use advanced materials such as glass, metal, engineered stone, and acrylic
• Common color schemes include white, gray, and black, often enhanced with LED lighting accents
• Clean, sharp lines dominate; handcrafted or ornate details are kept to a minimum
• Technical systems (lighting, electrical, audio) must be planned from the earliest design stage

Application examples:

• A smart-home apartment with lighting that automatically adjusts throughout the day
• A Hi-Tech kitchen featuring built-in appliances, flat surfaces, and handle-less cabinetry → exceptionally sleek and modern

II. Nordic & Japanese-Inspired Interior Design Styles: Minimalism with Emotional Depth

5. Scandinavian Style: Bright, Balanced, and Comforting

Scandinavian style is one of the most beloved interior design styles in Vietnam thanks to its harmonious balance between aesthetics, functionality, and emotional comfort. Originating in Northern Europe, where long winters and limited daylight are common, this style places strong emphasis on natural light, bright color palettes, and creating a warm, welcoming living environment.

Scandinavian interiors are never flashy or overly ornate, yet they offer a distinct sense of ease and livability. At RED, we often describe Scandinavian as a “highly livable” style: it adapts well to many housing types and can be easily adjusted to suit tropical climates through thoughtful material choices.

Core principles of Scandinavian interior design:

• Light, airy color palettes using white, cream, beige, and soft gray as a base
• Light-toned wood furniture (oak, ash, light veneers) to add warmth
• Maximum use of natural light with large windows and sheer curtains
• Simple furniture designs with raised legs to create a sense of openness
• Minimal yet cozy décor, including indoor plants, woven rugs, linen, and cotton textiles

Practical examples:

• A young family apartment with a Scandinavian living room featuring a light-gray sofa, pale wood coffee table, and plush rug → bright, friendly, and inviting
• A Nordic-style bedroom with white walls, a low wooden bed, and warm ambient lighting → relaxing and sleep-friendly

6. Japandi Style: Where Nordic Comfort Meets Japanese Calm

Japandi is a refined fusion of Scandinavian warmth and Japanese minimalism, blending Nordic functionality with the quiet, meditative qualities of Japanese design. Among contemporary interior design styles, Japandi is highly regarded for its emotional richness and the quality of everyday living it offers.

Japandi spaces emphasize calmness, order, and balance. Every detail is carefully considered, restrained yet never cold. RED often recommends Japandi to clients seeking a slower-paced home environment, a personal retreat from the demands of urban life.

How to design an effective Japandi interior:

• Use warm, muted neutral tones such as beige, light brown, warm gray, and earthy shades
• Choose low-profile furniture with simple forms, favoring natural or matte-finished wood
• Limit decorative items so each piece has a clear purpose and place
• Combine natural daylight with soft, indirect lighting
• Incorporate Japanese elements such as sliding doors, wooden slat partitions, and minimalist handcrafted objects

Real-life applications:

• A Japandi living room with a low sofa, solid wood coffee table, and gentle lighting → calm, grounded, and meditative
• A Japandi bedroom featuring a simple wooden bed, beige walls, and textured fabric curtains → peaceful and private

7. Wabi-Sabi Style: The Beauty of Imperfection

Wabi-Sabi is perhaps the most philosophically rich of all minimalist interior design styles. Rooted in Zen Buddhism and Japanese aesthetics, it celebrates imperfection, impermanence, and the quiet beauty of natural aging.

Wabi-Sabi interiors do not strive for flawlessness. Rough textures, uneven surfaces, subtle cracks, and muted tones are embraced as part of the space’s character. At RED, we often advise clients to choose Wabi-Sabi only if they genuinely appreciate simplicity and are drawn to a slower, more mindful way of living.

Key principles of Wabi-Sabi interior design:

• Emphasize natural materials such as raw wood, stone, cement, and handmade ceramics
• Use earthy, subdued color palettes: brown, gray, beige, and soil-inspired tones
• Preserve natural textures rather than over-polishing surfaces
• Keep furniture minimal but soulful; avoid mass-produced, overly industrial pieces
• Treat natural light as the most important design element

Application examples:

• A Wabi-Sabi living room with textured plaster walls, a raw stone coffee table, and solid wood seating → serene, artistic, and deeply calming
• A Wabi-Sabi bedroom stripped down to essentials—bed, bedside light, and natural daylight → encourages deep relaxation and mental clarity

III. Classic & Luxury Interior Design Styles: Timeless Elegance

8. Classic Style: The Benchmark of Refined Luxury

Classic design represents the most formal and enduring expression of luxury among interior design styles. Rooted in 17th-century European architecture, this style is defined by golden proportions, symmetrical layouts, and exquisitely detailed ornamentation. Every Classic interior carries a sense of prestige, permanence, and timeless beauty.

At RED, we see Classic design not as an excess of decoration, but as precision in every line and proportion. When executed correctly, Classic interiors feel grand and dignified, yet balanced and deeply sophisticated rather than overwhelming.

Defining characteristics of Classic interior design:

• Symmetrical layouts with clear spatial axes
• Decorative moldings and intricate carvings on walls, ceilings, and furniture
• Premium materials such as solid wood, marble, plated metals, and leather
• Elegant color palettes including cream, soft gold, rich wood tones, and classic blue
• Warm lighting, with statement chandeliers serving as focal points

Important considerations:

• Classic design works best in spacious interiors with high ceilings
• Skilled design and construction teams are essential to achieve proper proportions and detailing
• Investment costs are typically higher than for modern interior styles

Application examples:

• A villa living room with soaring ceilings, ornate moldings, and high-end leather sofas
• A Classic bedroom featuring a grand carved wooden bed and layered, heavy drapery

9. Neoclassical Style: Classic Elegance, Reimagined

Neoclassical style is a contemporary interpretation of Classic style: simplified, refined, and adapted for modern living. While ornate details are reduced, the essence of elegance remains intact. This is one of the interior design styles RED most frequently applies to townhouses and high-end apartments in Vietnam.

Neoclassical interiors strike a harmonious balance between traditional beauty and modern comfort, aligning well with the aesthetic preferences of today’s homeowners.

Key features of Neoclassical interiors:

• Structured layouts without rigid symmetry
• Subtle, well-proportioned moldings that highlight key wall areas
• Furniture with gentle curves and streamlined silhouettes
• Sophisticated neutral palettes: white, cream, gray, and deep navy
• A thoughtful blend of classic and contemporary materials

Tips for effective implementation:

• Limit decorative moldings to one or two accent walls to avoid visual overload
• Pair modern curved sofas with classically inspired tables or lighting
• Use lighting strategically to accentuate architectural details

Real-world examples:

• A luxury apartment designed in white and gray tones, featuring light moldings and refined pendant lighting
• A Neoclassical bedroom with an upholstered headboard, minimal moldings, and warm ambient light

10. Art Deco Style: Bold Glamour and Artistic Expression

Art Deco is a luxurious style with a strong artistic identity, emerging in the 1920s. Among high-end interior design styles, it stands out through its geometric forms, dramatic contrasts, and lavish materials.

This style isn’t for everyone, but when done right, it creates a striking, unforgettable impression. RED often recommends Art Deco for spaces that call for individuality and bold character.

Hallmarks of Art Deco interior design:

• Geometric motifs such as zigzags, fan shapes, and angular lines
• Opulent materials including marble, gold-plated metal, glass, and leather
• High-contrast color schemes: black and gold, emerald and brass, black and white
• Strong, sculptural furniture forms
• Artistic accents like statement mirrors, artwork, and designer lighting

Design considerations:

• Careful control of decorative elements is essential to avoid heaviness
• Best suited for larger spaces with high ceilings
• Requires a cohesive design approach from architecture through interior details

Application examples:

• An Art Deco living room with velvet seating, stone tables, and metallic lighting fixtures
• A hotel lobby or luxury apartment featuring a geometric-patterned accent wall

11. Baroque – Renaissance – Queen Anne

(European Royal-Inspired Styles)

This group represents the most opulent and historically significant classical interior design styles, closely associated with European royalty, aristocracy, and landmark heritage buildings. Their defining qualities include grandeur, ornate detailing, and exceptional artistic craftsmanship.

RED typically does not recommend applying these styles in full to modern residential interiors. However, selectively drawing inspiration from their essence can add a powerful sense of drama to special spaces.

Shared characteristics:

• Extremely elaborate ornamentation and intricate carvings
• Large-scale, statement furniture pieces
• Luxurious materials and rich, royal color palettes
• Spaces that demand very high ceilings and generous floor area

Smart application tips from RED:

• Avoid full replication; instead, use select elements such as chandeliers, chairs, or decorative motifs
• Best suited for grand foyers, formal reception areas, or feature spaces
• Balance with modern architectural foundations to prevent visual heaviness

Examples:

• A boutique hotel lobby inspired by Baroque design, highlighted by a dramatic chandelier
• A villa living room featuring a Queen Anne chair as a refined focal point

IV. Creative & Bold Interior Design Styles: Expressive and Full of Personality

12. Industrial Style: Raw, Honest, and Unapologetic

Industrial design is one of the most expressive interior design styles, known for its raw strength and honest use of materials. Inspired by old European factories and warehouses, this style embraces exposed structures rather than hiding them, concrete ceilings, visible piping, and bare brick walls become defining aesthetic features.

RED often recommends Industrial interiors to clients with strong personalities who value individuality over decorative polish. However, without careful handling of lighting and materials, Industrial spaces can easily feel cold or heavy.

Key principles of Industrial interior design:

• Preserve or replicate raw materials such as concrete, exposed brick, metal, and dark wood
• Avoid over-finishing; highlight natural textures and imperfections
• Dominant color palette: gray, black, brown, and metallic tones
• Simple, sturdy furniture with a focus on metal and wood
• Warm, yellow-toned lighting to offset the coolness of raw materials

Important considerations:

• Not ideal for very small spaces or areas with limited natural light
• Acoustic and thermal treatment is essential, as raw materials can amplify noise
• Introduce greenery or wooden elements to soften the overall atmosphere

Application examples:

• A creative studio with a concrete ceiling, solid wood desks, steel frames, and industrial pendant lights
• An Industrial-style café featuring exposed brick walls, large glass panels, and warm ambient lighting

13. Bohemian Style (Boho): Free-Spirited and Personal

Bohemian, often called Boho, represents freedom, creativity, and deep personal expression among interior design styles. Unbound by rigid rules, Boho interiors allow homeowners to mix colors, materials, and décor intuitively, guided more by emotion than convention.

RED finds Boho especially appealing to creatives, artists, and those who want their living space to clearly reflect their personality. That said, without a clear direction, Boho can quickly become visually overwhelming.

Defining traits of Boho interiors:

• Rich, earthy color palettes: terracotta, burnt orange, deep red, olive green
• Natural materials such as raw textiles, wool, rattan, bamboo, and wood
• Layered elements in rugs, cushions, and curtains
• Handcrafted décor and personal objects
• A strong presence of indoor plants

How to apply Boho effectively:

• Choose a dominant color tone to maintain visual coherence
• Group décor by material rather than mixing colors randomly
• Keep the spatial layout clear to avoid clutter
• Use natural light to soften bold colors and textures

Application examples:

• A Boho bedroom featuring woven rugs, patterned bedding, and rattan lighting
• A cozy Boho reading nook with an armchair, greenery, and freely arranged artwork

14. Maximalism: More Is Meaningful

Maximalism stands in complete contrast to Minimalism. Among interior design styles, it celebrates abundance, of color, texture, layers, and storytelling. Maximalism is not about chaos, but about intentional richness and bold combinations.

RED typically advises clients to choose Maximalism only if they have a strong sense of personal taste, as this style requires excellent control over the overall composition.

Key characteristics of Maximalist interiors:

• Bold, saturated colors with strong contrasts
• A rich mix of patterns, artwork, and collected objects
• Furniture from different styles unified by a shared theme
• Spaces that strongly reflect the homeowner’s identity

How to keep Maximalism cohesive:

• Define a clear central concept (color scheme, theme, or mood)
• Repeat certain elements, colors or materials, to create visual links
• Layer the space thoughtfully: background, focal points, and details
• Keep major surfaces (walls, floors) relatively stable and calm

Application examples:

• A Maximalist living room with deep-colored walls, a gallery-style art display, and a standout sofa
• A personal space showcasing collections of books, artwork, and travel memorabilia

15. Pop Art – Funky – Colour Block: Playful and High-Energy

This group represents the most youthful, daring, and energetic direction within creative interior design styles. Drawing inspiration from pop culture and contemporary art, these styles embrace vivid colors, bold graphics, and a sense of fun.

RED most often applies Pop Art, Funky, or Colour Block design to commercial spaces or areas that need a strong visual identity and immediate impact.

Defining features:

• Bright, saturated colors such as red, yellow, blue, and pink
• Clear forms and large blocks of color
• Iconic artwork, posters, and graphic décor
• Simple furniture silhouettes to balance the intense color palette

Tips for effective use:

• Limit the palette to 2–3 dominant colors to avoid visual overload
• Use large color blocks rather than scattered small accents
• Keep the background minimal so colors can stand out
• Best suited for short-term spaces or specific functional zones

Application examples:

• A Pop Art café with large mural-style wall graphics and colorful furniture
• A youth-focused fashion store using bold Colour Block layouts for strong brand recognition

V. Nature-Inspired & Sustainable Interior Design Styles: Living in Harmony

16. Rustic Style: Honest, Warm, and Naturally Grounded

Rustic design celebrates raw beauty, authenticity, and a deep connection to nature. Among interior design styles, Rustic stands out for embracing imperfection and prioritizing warmth, comfort, and emotional ease, much like a peaceful retreat in the countryside.

At RED, Rustic is often applied to garden homes, homestays, resort villas, or for homeowners who favor slow living and wish to escape the intensity of urban life.

Core characteristics of Rustic interiors:

• Natural materials with minimal surface treatment: raw wood, natural stone, handmade brick
• Exposed structures and honest construction that emphasize a sense of authenticity
• Warm, earthy color palettes: wood brown, beige, stone gray, soil tones
• Simple, solid furniture with a handcrafted feel
• A blend of natural daylight and soft, warm lighting

Important considerations when using Rustic style:

• Raw wood materials require proper moisture and pest treatment, especially in humid climates
• Avoid overloading small spaces with heavy materials
• Modern Rustic interiors are often softened with glass elements and thoughtful lighting

Application examples:

• A Rustic garden home with timber ceilings, stone flooring, and glass doors opening to greenery
• A Rustic-style homestay featuring reclaimed wood furniture and simple pendant lighting

17. Organic Style: Where Design Meets Well-Being

Organic design emphasizes a seamless relationship between people, architecture, and nature. Among sustainable interior design styles, Organic is not just an aesthetic choice, it is a mindset focused on supporting physical and mental well-being through thoughtful design.

RED considers Organic interiors especially suitable for eco-conscious lifestyles, families with children, or households with elderly members who value comfort and health.

Principles of Organic interior design:

• Soft, flowing forms with minimal sharp edges
• Natural, non-toxic materials such as wood, stone, clay, and organic textiles
• Nature-inspired color palettes: green, beige, brown, off-white
• Strong visual and physical connections to outdoor spaces
• Emphasis on natural ventilation and daylight

How to apply Organic design effectively:

• Use large windows and sliding doors to blur indoor–outdoor boundaries
• Introduce greenery in a controlled, intentional way
• Avoid glossy finishes and chemically intensive materials
• Select furniture with natural curves and organic silhouettes

Application examples:

• An Organic living room with rounded sofas, natural stone tables, and indoor plants
• An Organic bedroom featuring linen textiles, raw wood finishes, and soft ambient lighting

18. Eco-Friendly Style: Responsible Design for the Future

Eco-friendly design represents a responsible and forward-thinking approach within modern interior design styles. Eco interiors are not only visually appealing but also energy-efficient and environmentally conscious.

At RED, Eco design goes far beyond simply adding plants, it’s about aligning materials, functionality, and spatial operation to minimize environmental impact.

Key features of Eco interiors:

• Use of recycled or reused materials
• Preference for locally sourced materials to reduce transportation emissions
• Energy-saving design strategies for lighting and ventilation
• Durable furniture with long life cycles
• Reduced reliance on disposable items and excessive décor

Guidelines for implementing Eco style:

• Choose low-emission paints, adhesives, and finishes
• Maximize natural light and airflow to reduce energy consumption
• Use modular furniture that is easy to repair or reconfigure
• Integrate energy-efficient lighting systems

Application examples:

• An Eco apartment featuring reclaimed wood furniture and abundant natural light
• An Eco-conscious office using sustainable materials and thoughtfully placed greenery

19. Mediterranean Style: A Permanent Holiday Atmosphere

Mediterranean design embodies brightness, openness, and a close connection to coastal nature. Among nature-inspired interior design styles, it delivers one of the strongest resort-like experiences.

RED frequently applies Mediterranean interiors to beachfront villas, resorts, vacation homes, or for homeowners who want their living space to feel like an everyday escape.

Defining characteristics of Mediterranean interiors:

• Signature color palettes: white, ocean blue, turquoise, and sandy tones
• Arched forms and soft, flowing curves
• Natural materials such as stone, terracotta, and wood
• Open layouts filled with sunlight
• Strong visual connections to outdoor landscapes

Considerations for use in Vietnam:

• Adjust material choices to suit hot, humid climates
• Avoid overusing deep blue tones in smaller spaces
• Enhance natural ventilation to reinforce a cool, breezy atmosphere

Application examples:

• A seaside villa with whitewashed walls, arched doorways, and terracotta roof tiles
• A Mediterranean-style balcony featuring patterned tiles, greenery, and lounge seating

VI. Asian–European Fusion Interior Design Styles: Cultural Harmony

20. Indochine Style: Timeless East–West Elegance

Indochine is the most iconic example among Asian–European fusion interior design styles, blending classical French architecture with the spirit and materials of Southeast Asia. More than a design approach, Indochine represents a cultural identity, one that aligns beautifully with Vietnam’s climate, history, and aesthetic sensibilities.

At RED, we often describe Indochine as a “challenging but rewarding” style. When executed correctly, it delivers a space that feels elegant yet welcoming, rich in historical depth yet never outdated.

Core characteristics of Indochine interiors:

• French-inspired spatial layouts with high ceilings, large doors, and airy corridors
• Traditional Asian materials such as wood, bamboo, rattan, and patterned cement tiles
• Signature motifs including lotus flowers, geometric patterns, and traditional seal scripts
• Familiar color palettes: creamy white, soft yellow, warm wood tones, and black accents
• A thoughtful balance between decorative richness and everyday functionality

Important design considerations:

• Avoid overusing decorative patterns, which can make the space feel heavy
• Keep the color palette restrained and let materials and forms take center stage
• Best suited for high-ceiling townhouses, villas, and boutique hotels

Application examples:

• An Indochine living room with patterned tile flooring, wooden sofas, and a vintage ceiling fan
• An Indochine bedroom featuring a wooden bed, rattan headboard, and warm ambient lighting

21. Korean Style: Soft Minimalism with Emotional Warmth

Korean interior design represents a delicate fusion of modern Western minimalism and gentle East Asian sensibilities. Among cross-cultural interior design styles, it stands out for being youthful, adaptable, and well suited to contemporary urban living.

RED often recommends this style for compact apartments, young families, or anyone drawn to bright, uncluttered spaces that still feel warm and personal.

Key features of Korean-style interiors:

• Minimalist layouts with a strong focus on functionality
• Light, airy color palettes: white, beige, light wood, and soft pastels
• Low-profile furniture with smooth, gentle lines
• Abundant natural light throughout the space
• Minimal decoration with carefully chosen focal accents

How to apply Korean style effectively:

• Favor open layouts and limit solid partitions
• Choose integrated, space-efficient furniture
• Maximize natural light using light-colored curtains
• Decorate with monochrome artwork, small plants, and simple ceramics

Application examples:

• A 50–70m² Korean-style apartment with an open living and kitchen area
• A Korean-style bedroom featuring a low bed, light-toned walls, and simple bedside lighting
