Joseph Dirand (born 26 March 1974) is a French architect and interior designer based in Paris.
Dirand was born in Paris; his father, Jacques Dirand, was a photographer specialising in interiors and his mother was a fashion designer. He studied architecture at the École Nationale Supérieure d'Architecture de Paris-Belleville. As of April 2014 he lived in his own restored flat in the 7th arrondissement with his partner and their two daughters from previous marriages. Dirand works in Paris. After receiving the commission while still a student to do the interior design for Junko Shimada's Paris shop, he started his own interior design firm in 1999, when he was 25, and drew public attention with his redesign of a flat facing the Place de la Concorde. After his creation of the new shop for Balmain on rue François-Ier, which has been called "the most beautiful fashion store in Paris", he came to be in demand as an interior architect for fashion companies.
