A farmhouse for sale in Charente-Maritime (17), a barn to convert or a Charentaise longère with a few hectares of pasture or old vines: this department, historically built on mixed farming and livestock, still holds a dense stock of limestone farm buildings scattered between the marshes and the vineyard. This page brings together the farmhouses, barns and mas for sale in Charente-Maritime published on ma-propriete.fr: a borderie with outbuildings, a canal-tile barn waiting to be converted, a former farm with land, buildings close to the coast or to the marshland.
Below you will find the actual prices of the Charente-Maritime rural market, an overview of where to look, from the Rochefort basin to Haute-Saintonge, and the points to check before buying a former farm building. If your project is tourism-related, our white paper on setting up a rural gîte will help you cost it.
There are no statistics dedicated to farmhouses and barns: a renovated farmhouse sells like a country house with outbuildings and land, whereas a bare barn or a farm to renovate often sells well below. The most useful benchmark therefore remains the price of country houses.

A departmental average hides large gaps. A smallholding to renovate, a restored longère with its outbuildings, a farmhouse on several hectares of land or a manor house with parkland do not sell at the same price, and the location matters as much as the building: coastline, tourist area, peri-urban countryside close to a job market or deep countryside. The table below shows the median price of country houses in Charente-Maritime (17) by type of municipality (cumulative sales from mid-2020 to 2025) and its change between 2021 and 2025.

The Charente-Maritime farmhouse is often a borderie or a longère built of dressed limestone, topped with canal tiles, with a dwelling, a cowshed, a shed and sometimes an old cognac or pineau cellar. The outbuildings are arranged around a closed or U-shaped courtyard depending on the area. There is no mas in Charente-Maritime: the word does not belong to the local vocabulary, unlike in the south-east of France.
These volumes, often completed by an old cellar or a separate barn, lend themselves to conversion into a main home or several gîtes, subject to the local plan's zoning. The attached land, from a few thousand square metres to several hectares of pasture or former vineyard, suits horses, extensive grazing or a permaculture project near the Marais Poitevin or the Brouage marshes.
The northern part of the department, around Surgères, Aigrefeuille-d'Aunis and the Aunis plain, has a steady supply of farms and barns to renovate. In Haute-Saintonge, around Jonzac, Montendre and Montlieu-la-Garde, wine-growing farmhouses sit alongside arable land. Around Saint-Jean-d'Angély and the Boutonne valley, supply remains plentiful. Towards Saintes and the Charente valley, former tenant farms blend into the Cognac vineyard.
Close to La Rochelle, Rochefort and the coast, the Île de Ré or the Île d'Oléron, renovated farmhouses are rare and noticeably more expensive. Around Marans and the Marais Poitevin, former mixed-farming buildings remain more affordable but often call for care over damp and drainage.
Check the buildings' permitted use under the local plan: a barn located in an agricultural zone can only be converted into a home if the regulations explicitly allow it. Inspect the roof (canal tiles, but also asbestos-cement sheets on more recent sheds), the timber frame, the individual drainage system, often tricky in marshland areas, and any fuel tanks or manure pits that may need cleaning up.
If farmland comes with the buildings, ask about any current farm lease and about the pre-emption right of the Safer, active across much of the department. Finally, budget the renovation carefully: bringing a barn or a former borderie up to standard is often an investment comparable to the purchase price of the property itself.
