  1. Ignoring Proper Space Planning

    Poor vs proper space planning

    Poor space planning can make a room feel cramped or awkward. Furniture should allow easy movement and suit the room’s proportions.

  2. Choosing the Wrong Furniture Size

    Wrong furniture size comparison

    Oversized furniture can overpower a room, while undersized pieces may look awkward and impractical.

  3. Poor Lighting Design

    Poor vs layered lighting design

    Relying on a single light source often results in dull interiors. A layered lighting approach creates depth and comfort.

  4. Ignoring Natural Light

    Blocked windows vs natural light

    Blocking windows with heavy curtains or furniture reduces brightness and ventilation.

  5. Using Too Many Colors

    Too many colors vs balanced palette

    Too many colors can overwhelm a space. A controlled palette creates harmony and elegance.

  6. Lack of Storage Solutions

    Cluttered vs organized living space

    Insufficient storage leads to clutter and disorganization.

  7. Forgetting About Functionality

    Impractical vs functional interior design

    Design should support daily activities. Overly decorative spaces may lack practicality.

  8. Incorrect Placement of Rugs and Curtains

    Incorrect vs correct rug and curtain placement

    Incorrect rug size or curtain height can visually distort a room.

  9. Not Personalizing the Space

    Generic vs personalized interior design

    A home without personal touches can feel cold and impersonal.

Conclusion

Avoiding these interior design mistakes helps create spaces that are comfortable, functional, and timeless. Thoughtful planning, balanced design choices, and attention to detail make all the difference.
