Founded by Gauthier Demumieux and Felix Heger, both architects by training, our brand is distinguished by a unique vision that fuses architecture and object design: at Collateral Edition, we collaborate with architects who, like the great design masters of the 20th century, possess a keen sense of detail and boundless creativity. These collaborations enable us to create original and exclusive pieces, produced in limited series, that embody the essence of architecture and design.

Our creations are aimed at a passionate public, connoisseurs and enlightened amateurs who seek objects that tell a story and bear witness to the harmonious encounter between functionality and aesthetics. Each piece we create is the fruit of a passionate collaboration, where the expertise and enthusiasm of our designers are transformed into exceptional objects.

Our philosophy

At Collateral Edition, we believe that design is a natural extension of architecture. Our objects are conceived with particular attention to materials, shapes and proportions, creating a perfect harmony between the object and its environment. We strive to push the boundaries of design by exploring new ideas and collaborating with talented architect-designers.

Our commitment

We are committed to producing high-quality objects that are not only beautiful but also durable. Each piece in our collection is crafted with care and respect, using premium materials and innovative production techniques. We believe in creating objects that stand the test of time and continue to inspire and amaze.
