YJ Concept designs interiors inhabited by materials, for families attached to the places they live in.

Interior architecture studio founded in 2014. We lead three projects a year, in France and abroad, from the first visit to the final handover.

— The studio

12 people, two locations (Châlons-en-Champagne & Paris), three concurrent projects.
