In 2016, major works were launched to address the problem of saturation of the site. In fact, the capacity of 60,000 people was no longer sufficient for the 250,000 visitors who wandered there each year. The renovation project imagined by Jean-Paul Philippon included the creation of a new 1600 m2 wing and the rehabilitation of 700 m2 of the existing museum. The project also included the creation of a room dedicated to the history of Roubaix, a gallery dedicated to the history of modern sculpture, a second room for temporary exhibitions, spaces reserved for the museum's textile collection and a hosting artistic workshops for young audiences.
After a festive weekend, the Swimming Pool closed on April 2, 2018 for a period of six months in order to redesign all the spaces for the arrival of the new collections in the fall. An important work of restoration, inventory and installation could thus be done without disturbing the public.
