We create interiors that are as enduring as they are expressive. Founded in 2018, Theory Design is a leading luxury interior design firm in Southwest Florida, committed to timeless, personalized design.

Our team, led by Ruta Menaghlazi, VP of Design, consists of seasoned designers, creative thinkers, and project collaborators who are passionate about natural beauty, refined simplicity, and meaningful detail. We believe design is an experience that honors both the architecture of a space and the lifestyle of the people who inhabit it.

Our interiors are influenced by organic textures, earthy palettes, and the soulful craftsmanship of artisan-made elements. The result is warm, balanced, and deeply personal spaces that tell your unique story.

We approach each project—whether new construction or renovation—with fresh eyes, intention, and a deep respect for every client's unique story. We work closely with builders, architects, and homeowners to create effortless, authentic, and truly lasting spaces.
