About Us

Residential Interior Design

We believe that building relationships with our clients is the secret sauce to delivering the perfect space for your individual needs. Exceptional design can be intimidating. We want to be your most trusted adviser through the entire process.


With precise attention to detail, and unmatched customer service, our goal is to help you create a space that looks and functions beautifully for years to come. 


After several years of serving clients in the Effingham, IL area, we relocated to the greater St. Louis area to continue providing exceptional Interior Design services. 

We've worked with clients on a wide range of renovations, from bathroom/kitchen remodels to full basement transformations & new builds. We'd love to hear from you about your next home project!

"Kelsey was fabulous to work with on 2 separate rooms in our home. Her designs fit our personalities and our budget perfectly. She provided several options with visual aids for us to choose from. She responded quickly to any questions that occurred during each remodel process. We look forward to working with her again in the future!"

Our Story

Our Story

Kelsey is the design behind Design No. 7 Interiors. After working for a time at a commercial architecture and design firm in St. Louis, she now runs the design side of the business full time. She has a background in interior design, graduating from Indiana State University with a degree in Interior Architecture Design. Austin, the financial brains behind this operation, graduated from SIUE with a degree in education. He currently works as a middle school mathematics teacher & basketball coach in Troy, IL.​

Kelsey started this whole operation in college. Shortly after graduation, we began talking about using Design No. 7 in a more impactful way. We believe at our core that we were put on this earth to serve others, and designing homes tailored to each of our clients' lives allows us to do just that! We value the relationships we build with our clients above all else. The combination of Kelsey's eye for great design and Austin's heart of a teacher drives our very personal design process.

We all want a space where our family can thrive, whether that is two people or twenty. At Design No. 7, we believe in creating a simplified process that meets your specific needs. Helping you bring your family and friends together is at the core of what we do here.
