Founded by Julien Sebban, Uchronia is a Paris-based architecture and design studio conceived more as a multidisciplinary collective than a traditional architectural practice. Taking its name from the idea of fictional time and the ephemeral, the studio creates contemporary “places of experience” where architecture, design, scenography and visual identity come together.

Known for its bold use of colour, material experimentation and playful spatial compositions, Uchronia removes the boundaries between technique and creativity. From restaurants and private apartments to fashion shows and hospitality projects, the studio transforms spaces into immersive environments with a strong and singular identity.

Drawing from art, pop culture, fashion and historical references, Julien Sebban develops a vibrant design language that is both expressive and contemporary. His work has been presented at international design fairs and through high-profile projects, establishing Uchronia as one of the most distinctive voices on the French design scene.
