Interior Design Mistakes to Avoid in 2025
When renovating your home, not everyone has a keen eye for detail and the creativity required for design.
Without the guidance of a professional designer, it can be difficult to choose the ideal furniture combination while staying within your budget.
You might find some great furniture and decorative pieces at a furniture store, but that doesn't necessarily mean they will complement your home's overall décor.
Mistakes to Avoid When Designing Your Home
While decorating your space is a personal decision, a professional interior designer can help you explore your unique style preferences and create a custom look tailored to your wishes.
Whether you're pursuing a trendy design style or prefer a more classic aesthetic, it's easy to make common renovation mistakes. However, a professional interior designer can quickly spot them and guide you on how to quickly correct them.

- Using Cool Gray Tiles Throughout Your Home
The "high-grade gray" tiles that were all the rage online a few years ago are now experiencing aesthetic fatigue. While the cool hue creates a sense of simplicity, it can easily make a space lack warmth over time.
In homes with poor lighting, gray tiles can appear even more depressing. 2. Choose paint before adding furniture
The mood of a room depends on its color scheme, and the wrong combination can disrupt the overall atmosphere of the space.
Choosing a paint color before purchasing furniture is never a good idea, as it's easier to change the color of a sofa than to change it. People often make this mistake and end up struggling to find furniture that meets their style and budget.
- Poor lighting
Lighting design is often considered an afterthought in the design process, leading to either a narrow selection of lighting options or installing lights that are inappropriate for the size of the room.
Many people overlook lighting design when it comes to interior design, but a trained interior design professional can help you differentiate between task lighting, ambient lighting, and general lighting.
Before installing these products, it's important to evaluate the type of lighting you need and stay current with the hottest trends in this market segment to purchase the right lighting for your home.
This includes installing dimmer switches to balance the light intensity in the room and ensure adequate lighting.
- Buying too much furniture
No matter how expensive, clutter is never a good design principle.
Too many tables, mirrors, seating arrangements, and so on can ruin the aesthetic of a design. Clutter also appears tasteless and limits space for movement.
The best way to prevent this clutter is to remove unnecessary pieces from the room to make it look more organized. Home interior designers recommend leaving 30 inches of space between furniture to facilitate movement around them.
- Cluttered Wall Art
Adding a modern look to your decor with the right artwork is a great design touch. However, arranging it incorrectly can bring the entire space down.
Common mistakes include mounting it too high or too low on the wall. This disrupts its alignment with the furniture and disrupts the room's overall design.
This mistake can be avoided by placing the pieces 8 to 10 inches higher than the furniture, resulting in a beautifully designed room.
So, avoid these mistakes when designing your home. Embark on your home design journey with confidence and create a space that's truly yours. Of course, if you're still unsure of your desired design style and feel overwhelmed by the many ideas, consult a professional interior designer at Xishu Kejian to help you make the right decisions and begin your journey to a truly unique home.
