For Uchronia World, Julien Sebban transforms his Paris apartment into a living manifesto for the studio’s joyful and radical design language.

Located near Uchronia’s studio in the 18th arrondissement, the apartment becomes an immersive laboratory where colour, texture and craft take over from conventional neutrality. Lacquered ceilings, mirrored mosaics, Japanese silver leaf, bold pictorial finishes and unexpected material combinations create a world that feels both intimate and dreamlike.

Custom-made furniture, vintage finds and collaborations with specialist artisans give each room its own identity, from the celestial-blue living room to the sunlit yellow bedroom and orange guest room. Through this personal project, Uchronia turns domestic space into an expressive work of art, where imagination, craftsmanship and everyday life come together.
