The first stone of the ATOM residence was laid on Friday, October 2, in the Menpenti neighborhood of Marseille. This project includes 97 social housing units aimed at young workers, students, and apprentices, as well as the relocation of the Saint-Éloi workshop. The development is a joint effort by the social housing company 3F Résidences, a subsidiary of Action Logement, and developers Océanis and Immostone. The site is located on rue Jacques-Hébert, in the 10th arrondissement of Marseille. The ATOM residence is being built near the 26th Centenary Park and is expected to be completed by the end of 2027. It will offer 97 apartments, including 102 units, designed for young people with incomes that are modest. Élisabeth Novelli, general director of 3F Résidences, emphasized the importance of accessible housing for young people, stating that it is difficult to build a future if one cannot find housing near where they work or study. Audrey Garino, deputy mayor of Marseille in charge of housing, highlighted the challenges young people face in finding affordable and accessible housing in the city. She noted issues such as precarious employment contracts, low incomes, and the difficulty of meeting the financial guarantees required by landlords. She also pointed out the limited availability of housing for this demographic in Marseille. The six-story building will feature 31 studios, 61 one-bedroom apartments, and five two-bedroom apartments. Managed by the association Vivacité, the residence will be open to students, apprentices, and young workers, including some from the Child Protection Services (ASE). Common areas such as a cafeteria, a laundry room, a co-working space, and a bike storage room will be available for residents. The location is near public transport and the Timone campus, with a tram stop about 400 meters away and two metro stations accessible on foot. The Saint-Éloi workshop, which is linked to the École des Beaux-Arts de Marseille, will be temporarily relocated during the construction. It will return to its original site at the foot of the future building, occupying 250 square meters. The building, designed by architect Didier Roche, will have a stepped silhouette to blend with the surrounding urban environment, which includes buildings of varying heights from two to eight floors. A green space will be created at the center of the ATOM residence, featuring a terrace and tall trees to provide a cooling effect. The City of Marseille has sold a municipal land plot and another parcel to Immostone to help realize the project. It also guarantees 50% of the total loan, which amounts to 5.2 million euros. Additional financial support comes from the State, the Aix-Marseille-Provence Metropolis, the Banque des Territoires, and Action Logement. Audrey Garino noted that the project aligns with the city's broader goal of providing housing solutions that adapt to the changing needs of its residents throughout different stages of life.
