In 1999, Chahan Interior Design established itself with a discreet showroom in the heart of Carré Rive Gauche to welcome its clientele. This multicultural activity, combined with its distinctive aesthetic, has enabled it to develop and assert the “Chahanian” style: a blend of textures, lighting, rare collections, pure lines, historical references, and timeless design—all presented in luxurious, serene, and highly personalized settings.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 antiques and design fairs such as the Pavillon des Antiquaires, the Pavillon des Arts et du Design, Collective Design, and The Salon New York introduced its vision and aesthetic to an international audience.

In February 2008, Chahan Gallery opened its doors at 11 Rue de Lille, allowing it to expand the visibility of its offerings and present exceptional collections of mid-20th-century furniture. It also hosts twice-yearly exhibitions dedicated to the artists it represents.
