Located in the heart of the 5th arrondissement, Les Petites Serres was a 4,700-square-meter temporary space awaiting the completion of a hotel project. Featuring a unique layout that combined a listed mansion with industrial spaces under a glass roof, this venue hosted a diverse yet complementary mix of project leaders: sustainable development startups, neighborhood associations, artists, real estate firms, architects, and more. The Aurore association had also set up temporary housing there.
