about us

After gaining five years of professional experience in Marseille and then on Lille 2004, the European Capital of Culture, Grégoire Cartillier worked in Nantes for ten years as technical director of the “Estuaire” contemporary art biennale and then for “A Journey to Nantes”.

As a registered architect (DPLG), he has in-depth knowledge of urban planning issues and helps many artists set up installations with complex anchoring points. As a consultant with ministerial working groups, he also advises on issues related to the development of artistic commissions for public spaces, with an emphasis on the sustainability of artworks.

Over the course of 15 years, he has acquired recognised expertise in the study and direction of exceptional, non-standard creative projects.

In the autumn of 2016, he founded Ateliers Puzzle.
