Kristine Irving’s path began in retail, where she cultivated an intuitive understanding of how objects, materials, and environments give form to the personal narratives that define our lives. What began as an art gallery evolved into a series of home stores, each defined by a layered, curatorial sensibility and an appreciation for the sensory richness found in everyday living. As clients returned seeking more than objects—asking for guidance in shaping their homes—the transition into residential design emerged organically, grounded in both entrepreneurial instinct and creative evolution.
Today, Kristine leads a small, tightly held studio working with a private, discerning clientele on complex residential projects. Operating as both artist and observer, she approaches each home with a considered, deeply collaborative mindset—balancing intuition with discipline and resonance with restraint. Known for creating interiors characterized by both refinement and juxtaposition, her work embodies a balancing act between old and new, history and invention, precision and soul.
STUDIO
Koo de Kir is a full-service interior design studio working with clients around the globe on ambitious, value-aligned projects. We view design as a means of translation, giving form to the architecture of one’s life and heritage. Rooted in equal measures of artistry and intention, our work expresses a refined, deeply collaborative approach to spatial storytelling—one that resonates instinctively and often unexpectedly.
SENIOR PROJECT MANAGER
Caitlin Berger
California-raised and Boston-educated, Caitlin Berger's path back to Koo de Kir has been anything but conventional. After an early chapter with our retail division, she headed to New York to pursue dual passions in acting and design. During her time at Celerie Kemble Interiors, Caitlin discovered a deep appreciation for the transformative power of interior design, an experience that solidified the direction of her career. Following a brief stint in public relations, she returned to Boston and reconnected with Koo de Kir, this time with her sights set firmly on the design world. Fortunately for us, it was a perfect match. Today, as Project Manager, Caitlin oversees the execution of our construction and interior architecture projects, bringing clarity, organization, and thoughtful leadership to every stage of the process.
