In 1999, Chahan Interior Design established itself with a discreet showroom in the heart of the Carré Rive Gauche, where it welcomes its clientele. This multicultural activity, combined with its distinctive aesthetic, allowed it to develop and establish the “Chahanian” style: a blend of textures, lighting, rare collections, pure lines, historical references, and timeless design—all presented in luxurious, serene, and highly personalized settings.

From 2001 onward, its participation in numerous antique and design fairs such as the Pavillon des Antiquaires, the Pavillon des Arts et du Design, Collective Design, and The Salon: Art + Design in New York introduced its vision and aesthetic to a wider public.

In February 2008, Chahan Gallery opened its doors at 11 Rue de Lille, expanding the visibility of its offerings and presenting exceptional collections of mid-20th-century furniture. The gallery also hosts, twice a year, exhibitions dedicated to the artists it represents.
