Urban renovation of Franc-Moisin in Saint-Denis: rehousing, demolitions, rehabilitation. Started in 2021, the 177 million euro operation led by the National Urban Renewal Agency was the subject of a meeting this Saturday.

B4 is the name of the building of 291 social housing units from landlord Logirep, the last three levels of which are being trimmed. Before disappearing from the city's landscape, the 13-story ghost building still dominates the Descartes school - also slated for destruction in mid-2026.
