Award-Winning
Boutique Interior Design in Naples, FL

Kate Killeen Design is a full-service luxury interior design studio in Naples, Florida, founded in 2021 and led personally by principal designer Kate Killeen. The studio designs new construction, whole-home renovations and select hospitality spaces for clients across Naples, Bonita Springs and Southwest Florida.

Kate came to design after more than a decade guiding luxury clients through high-stakes decisions. She got her start apprenticing inside a design-build firm, where she learned construction from the ground up and saw how exceptional homes actually come together on site. She also saw what clients were missing: one person who stays with them from the first handshake to the final install.

So Kate built a different kind of studio, one where she leads every project herself, from start to finish. With a deliberately small client roster, Kate has the time to know your project inside and out, and the candor to tell you what it really needs. One designer. One clear point of view. Straight answers about budget, timing and tradeoffs. Her promise to clients is simple: no handoffs, ever.

Kate’s proprietary process, the Private Client Standard™, brings rare structure to that personal approach, anticipating and sequencing the thousands of decisions behind a finished home. Her design work reflects the same clear judgment. Instead of a signature style, Kate brings a signature sensibility: knowing when a space should quietly breathe and where it should go bold.

Her work has been featured in multiple publications, including Naples Illustrated, Florida Design Magazine and Design + Decor. In 2026, Project Vanderbilt was named a Seaglass Awards Finalist in Small Space Design. For Kate, this is only the beginning.
