Can I convert a barn or bergerie into a house in Provence?
Short answer
Not always. Most agricultural outbuildings in Provence sit in PLU zone A (agricultural) where residential conversion is restricted. Even where the PLU allows a changement de destination, the density of ABF heritage zones in the Luberon and Alpilles means you will almost certainly need Architectes des Bâtiments de France approval — adding months and material constraints to any project.
In detail
Many Provence properties — mas, bastides, domaines — come with outbuildings: bergeries (sheep shelters), hangars, cabanons, or old magnaneries (silkworm houses). Buyers often assume these can be converted into gîtes, guest houses, or extra living space. The reality is more complicated.
The PLU zone problem
Most rural outbuildings sit in PLU zone A (agricultural) or zone N (natural/forestry). In both zones, residential conversion — legally called a changement de destination — is restricted.
Zone A (agricultural)
Conversion is only possible if the building is listed in the PLU as a "bâtiment pouvant faire l'objet d'un changement de destination" (Article L151-11 of the Code de l'urbanisme). Many commune PLUs have not catalogued older outbuildings. If it is not on the list, conversion requires a PLU modification — a process that takes one to two years and is not guaranteed.
Zone N (natural)
Conversion is even more restricted. Only buildings of "architectural or heritage interest" identified in the PLU can change destination. In practice, this means most zone N outbuildings cannot be converted at all.
What this means in practice: Before buying a mas with outbuildings you plan to convert, request the PLU zonage map and the specific PLU article that covers the building. Your notaire should do this, but many do not check until it is too late.
The ABF layer
Provence has France's highest concentration of Monuments Historiques and sites classés. The Luberon alone has over 60 listed monuments. Within 500 metres of any listed building, the ABF must approve all exterior changes — including converting an outbuilding.
ABF approval for a barn conversion typically adds two to four months to the planning timeline, on top of the standard two-month déclaration préalable or three-month permis de construire. The ABF may impose material constraints: stone walls restored in local pierre du Luberon, roof tiles matching the commune palette (typically tuiles canal in terre cuite), and limited window openings to preserve the building's agricultural character.
Communes with AVAP or ZPPAUP designations — including Gordes, Bonnieux, Ménerbes, Les Baux-de-Provence, and Aix-en-Provence — have even more detailed architectural rules that override the standard PLU.
Agricultural buildings and SAFER
If the outbuilding sits on agricultural land, the SAFER (Société d'Aménagement Foncier et d'Établissement Rural) may have a pre-emption right over the sale. SAFER can intervene if it believes the land should remain in agricultural use. This is more common in the Vaucluse and Alpes-de-Haute-Provence than in urban Bouches-du-Rhône.
Realistic conversion costs
A bergerie conversion in Provence typically costs €1,800–€3,000 per square metre depending on the commune, ABF requirements, and the state of the existing structure. A 100 m² bergerie conversion in an ABF zone runs to €200,000–€350,000 including architect fees, structural work, and ABF-compliant materials.
The key question to ask before buying: is this outbuilding listed in the PLU as eligible for changement de destination, and does the commune have an AVAP or ABF zone that will constrain the project?
