Three talented French Craftsmen
dedicated to excellence

+33 Collectif epitomizes French artistry and ingenuity, bringing together the talents of three craftsmen to redefine luxury in the United States.
Our collective is based in New York City, but its roots lie in France, where the three workshops remain.

Founded by Emmanuel Barrois, Steven Leprizé, and Steaven Richard, +33 Collectif reinvents centuries-old traditions of working with glass, wood, and metal with a contemporary sensitivity. Our artisans blend traditional techniques with cutting-edge technologies to create innovative, one-of-a-kind pieces that inspire architects and interior designers worldwide.

We are dedicated to excellence and collaborate closely with the most discerning clients in the high-end luxury market to design bespoke pieces that will elevate their spaces. Though our strength lies in collaboration, we also provide the flexibility to work individually with any of the three workshops, offering tailored solutions to meet your specific needs.
