Diane is professional at every turn and a delightful person to have guide me in making major and minor changes in several rooms.

I never thought I'd employ the services of a san diego interior designer. The entire process was painless and the result is wonderful.

We absolutely recommend Diane and will use her expertise again.



Bella Designs was founded in 2002, after designer Diane Swenson found her client base growing beyond what she could service as a part-time job. Since then, the company has successfully completed projects for a variety of residential and commercial clients across Southern California (with a home base in San Diego) and Scottsdale, Arizona, earning accolades such as the design excellence award from San Diego Home/Garden Magazine and the Best of Houzz Customer Satisfaction for 2013.

Does your home or business need a facelift? Whether some minor tweaking is in order....or a complete overhaul, you will save yourself time and headaches by enlisting the aid of a client friendly company that offers professional design advice.


Diane earned a bachelor of fine arts degree, with an emphasis on interior design, from San Diego State University, which is accredited by the Foundation of Interior Design Education Research (now known as the Council for Interior Design Accreditation). Diane is also certified in "Feng Shui Friendly Design". She continually supplements her formal education by attending trade shows, seminars and conferences to remain up-to-date on the latest design trends.

San Diego Window Treatments

Installing window treatments is an excellent way to change the look of any room. Whether you seek to make a subtle change to an existing design.

San Diego Color Consulations
Color Consultation

Wall color, which often creates the initial impression of a room, is something that’s difficult to select for many people. Bella Designs can provide a palette of paint selections.

San Diego Space Planning

Space planning is a skill that separates interior designers from “mere mortals.” Most people find it difficult to visualize how items will look in a room, but designers are trained in doing just that.

San Diego Furniture Accessories
Furniture and Accessories

Making recommendations for new furniture and accessories—including items available from stores limited to designers—is just one way Bella Designs can help you change the look of a room.

San Diego Flooring

The variety of choices available for flooring today can be quite mind-boggling: carpet, wood, laminate, vinyl, and many types of tile. Bella Designs can help you decide what’s best for your needs, taking into account both usage and aesthetic concerns.

San Diego Model Home Staging
Model Home Staging

It’s no secret that four walls alone don’t go very far to sell a property; model homes are designed to attract buyers. Bella Designs has significant experience working with builders and Realtors to showcase properties in their best light.

The Process

Communication is vital when it comes to the design process, so at Bella Designs, we ensure that you understand up front what you should expect as we move forward. We maintain frequent contact during all phases of your project; we are available to answer any questions that might come up and provide guidance on demand as required. There are three important elements to our communication.



It’s certainly true that a picture is worth a thousand words, so we are pleased to present this gallery of before and after photos that document some of our many completed projects. Please feel free to ask for more information about specific work that catches your eye.


  • I never thought I'd employ the services of an interior designer, but after just about completing the look of my modern condo, I was stumped when it came to window treatments. Diane suggested some great alternatives and then provided me with wonderful fabrics from which to choose. The installer she recommended did a great job, too. The entire process was painless and the result is wonderful. Adrienne Moch

  • Diane is professional at every turn and a delightful person to have guide me in making major and minor changes in several rooms. I'll call her again. Patty Edwards

  • In our past experience with decorators, we felt the outcome reflected the designer's taste rather than our own. Our experience with Diane Swenson was entirely different. She got to know us, was able to combine practicality with elegance, and add a dash of fun. Diane helped us define and refine our ideas and choices, resulting in decor that suits our style and feels like our home. We absolutely recommend Diane and will use her expertise again.
