In 2021, she joins Galerie Downtown, founded in 1982 by François Laffanour, which has gained worldwide recognition over the decades for its exhibitions of Jean Prouvé, Charlotte Perriand and Pierre Jeanneret. For Luna, the temptation to continue the Downtown adventure is legitimate, as is the desire to emancipate, distinguish and invent. Luna believes in interdisciplinarity and exchange, a conviction certainly born of her bi-culture. In 2023, the Galerie Downtown, already contemporary and innovative, reinvents itself with the creation of a new downtown+ department designed by Luna Laffanour. She is now at the forefront of this project, taking a fresh look at the gallery's heritage through a cycle of both physical and digital exhibitions, blending design and contemporary art.
