Commercial Interior Design in Missouri
Our ‘Solutioneers’ are Commercial Interior Designers who hold degrees like interior design and architectural studies, and they’re some of the best in the business. Their talent helped to make us the premier interior design company in Columbia, MO. At Marathon, our Solutioneers believe in merging functionality with aesthetics, meaning we won’t just sell you something expensive and pretty; we suggest the most practical and efficient office furniture while adhering to your desired aesthetic. Our commercial interior design process offers flooring solutions, window treatment, desks, and workspaces, and everything commercial workspaces need to keep comfort and function at the forefront. It’s our clients’ needs that drive the design process, and our clever design solutions will cater to your taste while maximizing both the beauty and the efficiency of your space. Our clients have full control over the interior design process at every step, from furniture selection to renovation. We provide visual representations and 3-D renderings of our design plans so nothing gets done without the approval of our customers.
Regardless of your interior needs, we always recommend working with our design department; it creates a more streamlined process. We manage the work among other departments, saving our clients time so that they don’t have to. This also allows us to aesthetically coordinate the design. At Marathon, we love talking commercial interior design so whether you have questions about our services, or just want to talk about your favorite interiors, we’re only a phone call away.
Site Analysis
Whether you already have a vision for your space or you need a trained eye to help you combine the best colors, texture, and finishes, the expert Solutioneers at Marathon will guide you in analyzing your space and creating a design plan to give you the best outcome possible. During the site analysis process, our trained professionals will take measurements, photos, and determine the ways they can make your space fit your wants and needs. They will discuss the aesthetic and feel you’re hoping to achieve while keeping your budget and timeline in mind.
The way a space is put together shapes how people move through it, how they focus, and how clients perceive a business from the moment they walk in. Marathon’s design team handles that full picture. From material selection and finishes to color and spatial flow, we build environments that reflect your brand and support the people working inside them.

Communication with All Parties Involved
We know there may be several people involved in your interior design project, so it is crucial to keep an open line of communication between all parties involved. We pride ourselves on providing clear and detailed updates throughout the entirety of the project so that no one feels left in the dark. From the initial site analysis to the completion of your project, you will have one of our Solutioneers there with you every step of the way to answer questions and help you feel comfortable while we work together to craft your space the way you imagine it.
How long does a commercial interior design project take? Most projects move through planning, design development, coordination, and documentation phases. Timelines depend on the size and complexity of the space, but clients should expect several months from the first consultation to final sign-off.
Can commercial interior design be integrated with architecture? Yes. Marathon coordinates interior planning alongside architectural work so structural decisions and design decisions stay aligned throughout, rather than being reconciled at the end.
