Our Style: Organic Contemporary

At CeTerra, we define our style as organic contemporary.

What’s that mean?

We use lots of natural, custom finishes – wood and metals – in unique ways to create a warm and yet contemporary look. And we incorporate the individual style of our clients and their home into our creative interior design process. In this way we let our vision and your needs blend into one ideal design that really works!

The Design Process


The Studio at CeTerra Accents & Interiors begins the design process with an extensive interview of the client, a visit to the site if possible, or a review of architectural drawings to ensure that we are the right fit for your project. During this phase of the process, it is our objective to develop a concise understanding of your needs and personal preferences. We will ask questions concerning how you would like your space to feel and function as well as your desired timeline and budget. The end result is an action list which thoroughly defines your project.


Once we have identified the needs of our client, and analyzed the scope of their project, we will conduct research to determine the appropriate resources for finishes, furnishings, materials, and labor if needed. The Studio at CeTerra will guide you through those numerous options, and assist you in your selections to avoid time delays, and prevent costly mistakes. We utilize the latest technology in design to create precise furniture layouts for space planning; and concept drawings for remodeling, and new construction. Our related services also include colorization and accessorizing, creation and placement of botanicals, and the specification of window and wall treatments. We can design custom furnishings, access resources available only to the trade, and recommend the best artisans, craftsmen, upholsterers, installers, painters and contractors to bring your vision to life.


The Studio at CeTerra Accents & Interiors has the benefit of the long established partnerships within the complementary industries of interior design. We pride ourselves on our ability to create a collaborative and professional working environment with all parties involved in your project to ensure that every aspect will be performed to the highest standards. To achieve this objective, we rely on consistent communication with our client and contractors in addition to regular visits to the site to monitor progress.

Wonderful experience from concept to final product!

Working with Katherine Mueller of CeTerra Accents & Interiors was a wonderful experience from concept to final product. Katie helped transform our outdated house into a comfortable and stylish home. Each room flows beautifully and gracefully.

Katie and her staff always made my job a priority. Their dedication, creativity and responsiveness are exceptional. Katie’s taste and ideas captured everything I ever wanted in a home from the custom furniture, cabinets, and drapery to the rugs, paint and lighting. In addition to her design talent, she managed to coordinate the efforts of several parties in one project to be sure that the project kept moving in a timely fashion.

I don’t know what I would have done without her! I would not hesitate in recommending Katie and CeTerra Accents & Interiors.
