Former factories, shops, public buildings or disused agricultural sites: 20,729 brownfield sites listed, 352,644 hectares in total. For each one, the area, the status, the planning zone, and the link to its town’s property market.
Source: national brownfield inventory Cartofriches (Cerema), October 2026 version: sites not yet redeveloped, from local observatories, calls for projects and the former polluted-site inventories (Basias, Basol), not all of which have been verified. Sites belonging to private individuals are not shown. Areas: land unit.
We check with you the PLU rules, the usable area, pollution risks and the local market (building-plot prices, neighbouring sales), and we help you identify and contact the owner.
Before making an offer, you need to know what the property is worth here: actual recorded sales nearby, the effect of its energy rating (EPC), the cost of works, the planning rules for the plot. I go through this analysis with you, and an adviser from the network can visit it for you.
