In 2011, Boris Mathias founded Chapi Chapo Design, a name inspired by his French roots, with a clear mission: to craft bold, meaningful interiors defined by precision, character, and timeless sophistication.

What began as Boris’s personal design venture grew into a respected, full-fledged practice built on his vision and guided by a trusted, long-standing team. Over the years, his work expanded across luxury residential, hospitality, and bespoke commercial projects, earning recognition for a design approach grounded in intention, refinement, and integrity.

With this established foundation and a continued desire to push creative boundaries, Boris founded OPUS 356, a studio that reflects his experience, leadership, and unwavering commitment to meaningful, sophisticated design.
 
Opus speaks to the art of creation at its highest level, the pursuit of a signature work, crafted with vision and virtuosity, destined to leave a lasting mark.
 
356 pays homage to a pioneering sports car, a lasting symbol of craftsmanship, elegance, and innovation, and a reflection of Boris’s passion for speed, precision, and adrenaline.
 
More than a new name, Opus 356 represents a studio in motion, firmly rooted in its founder’s vision, driven by a commitment to excellence, and always pushing the boundaries of what thoughtful design can achieve.
