Award-Winning
Boutique Interior Design in Naples, FL

After more than a decade guiding private clients through high-stakes decisions, Kate Killeen left that career in 2018 without a Plan B and stepped into design, training inside a design-build firm where she learned how exceptional homes actually come together on site. She also saw what the industry was missing: one person who stays with the client from the first decision to the final piece.

In 2021, she founded Kate Killeen Design, a full-service boutique interior design studio built around a deliberately limited project roster and direct principal involvement from start to finish.

Every project is led personally by Kate and delivered through the Private Client Standard™, with never more than three homes in design at one time. This proprietary process anticipates and sequences the thousands of decisions behind a finished home, giving clients one designer, one clear point of view, and one consistent advocate from the first conversation through final installation.

Kate doesn’t design toward a signature look. She designs from a signature sensibility. Her interiors are layered, refined, and considered, with every decision grounded in context, shaped by architecture, and guided by the judgment to know when to push, when to edit, and when restraint is the stronger choice.

Her work has been featured in Naples Illustrated, Florida Design Magazine, and Design + Decor, and was named a finalist at the 2026 Florida Design Seaglass Awards for Small Space Design.
