Wherever
You Call Home.

Regan and her team provide full service interior design, both residential and commercial, nationwide.

Clients come to us when they want a space that feels considered rather than styled.  We create spaces that communicate through material, proportion, and history.  Spaces that feel intelligent, lived-in, and quietly confident. Craft matters. Longevity matters. Expression is intentional, never performative. We design at ease with restraint and presence, with heritage and modernity, with softness and structure. Nothing is about proving taste; everything is about living inside of it.

Aesthetically, our projects are based on timeless values such as clean lines, symmetry, proportion, and architectural detailing. In this way, our work feels inviting and familiar. We bring visual interest, personality, personal experience, and emotional connection into our designs through layering shape, color, texture, and pattern.

My approach to design is rooted in intention rather than display.

That philosophy was shaped early on.

I grew up in Maryland in a home my Francophile mother layered with Provençal ease and understated Parisian flair. Weekends were spent rummaging through the fabric shelves at Pierre Deux to make lampshades and wandering Antique Row in search of furniture with a past. She taught me that a home should be personal, comfortable, and original, never trend-driven, never overworked, always reflective of the people who live there.

Above all, she instilled in me a reverence for workmanship. That appreciation continues to guide my work today. I collaborate closely with artisans, artists, and trusted vendors around the world to source pieces with integrity. We source objects that carry cultural meaning, human touch, and lasting relevance. Years of cultivating relationships with independently owned and established businesses allow me to assemble thoughtful, highly skilled teams for my clients, ensuring each project is both creatively rich and impeccably executed.

Every home I design is meant to be lived in.  Spaces are not staged, not precious, but deeply functional, layered, and enduring. No two spaces are ever the same, because no two lives are.

When I’m not designing or spending time with my family, you’ll often find me open-water swimming. It’s where my mind quiets and my best ideas surface. That balance, between rigor and ease, intention and intuition, is the same balance I seek in every interior.

Design, to me, is not about making a statement. It’s about creating a place that feels unmistakably yours.

After receiving an undergraduate degree in art and art history, along with her degree in Interior Architecture and Design from the Pratt Institute, she honed her craft by working with some of the world’s leading designers, in both Los Angeles and New York, before establishing Regan Billingsley Interiors in 2013. She is a member of CBIA in Naples, Florida , ASID, and an Architectural Digest Pro Designer.

Design starts & ends with you.

We aren’t like other interior design firms. We create bespoke designs that are individualized to the people who experience them. We started our firm with the belief that good design can enhance quality of life. We see every design as an opportunity to weave experience, emotion, and connection into the world around us.

This belief is why we take a personal, client centric approach to our projects. Each project starts with a meeting between our clients and our Lifestyle Ambassador, so that from day one we understand our clients’ lifestyle, values, needs, goals, and desires.

Whether we’re crafting a space for entertaining, gathering, working, eating, or relaxing, the fundamental core of our design process is that it’s about you.
