A farmhouse and barn for sale in Marne (51), a large plains Champagne farmhouse or a barn to convert: this wine-growing and cereal-farming département has kept a substantial stock of farm buildings, between the Champagne hillsides and vast chalk plains. This page brings together the farmhouses, barns and mas for sale in Marne published on ma-propriete.fr: a plains farm with a square courtyard and a dovecote, a former wine-growing holding with a storeroom, a brick-and-chalk barn to convert, a farmhouse with farmland.
Below you will find the actual prices of the Marne rural market, an overview of where to look, from the chalky Champagne plain to the Marne valley, 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.
How much does a country house cost in Marne (51)? According to DVF data (notarised sales) analysed by the ma-propriete.fr observatory, the median price of a country house in Marne (51) stood at €180,000 in 2025, with an average price of €191,161 and a median price of €1,675/m² of living space (1,380 house sales in rural municipalities over the year). The price range is wide: 10% of houses sold for less than €90,000 (floor price, 1st decile) and 10% for more than €312,820 (ceiling price, 9th decile). The typical country house here offers 114 m² of living space on an average plot of 1,606 m², i.e. around 0.2 ha.

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 Marne (51) by type of municipality (cumulative sales from mid-2020 to 2025) and its change between 2021 and 2025.

| Peri-urban countryside (city catchment area) | €216,500 | €1,967/m² | +2.8% | 4,434 |
| Deep countryside (outside urban influence) | €142,700 | €1,380/m² | -0.3% | 3,915 |

Note: in Marne (51), the municipalities classified as "coastline" have no access to the sea. They are municipalities bordering lakes of more than 1,000 hectares (or, in Eure, the Seine estuary) covered by the 1986 Loi Littoral, which also applies to such inland lakes and estuaries.

The typical plains farmhouse in Marne is built around a closed square courtyard, with the dwelling, a barn and a shed arranged around the same complex in brick, chalk or millstone grit depending on the area, sometimes with a dovecote. In the vineyards, the wine-growing farmhouse is more modest, with an adjoining storeroom. There is no mas in Marne: the term has no local use here.
These buildings offer large volumes: a plains barn can become a home or a gîte, subject to local planning zoning. The adjoining farmland, often several hectares of arable crops, also lends itself to pasture for horses or a smaller-scale permaculture project.
The chalky Champagne plain, around Châlons-en-Champagne, Vitry-le-François and Sézanne, has the widest and most affordable choice of plains farms to renovate. Towards Fère-Champenoise and the south of the département, farmhouses dominate a landscape of arable land. Around Sainte-Menehould, in the Argonne area, buildings mix with forest.
Near Reims and the Montagne de Reims, as well as around Épernay and the Marne valley, former wine-growing farmhouses sell well above the départemental average, driven by the Champagne vineyards. The north and east of the département stay more accessible.
Check the change of use status in the agricultural zone of the local plan: a barn or agricultural shed can only be converted into a dwelling if the planning document allows it. Check the roof (flat tile, or asbestos-cement on more recent sheds), the timber frame and the drainage, worth checking in isolated plains hamlets.
If farmland is included, ask about any current farm lease and about the pre-emption right of the Safer (the French rural land agency), particularly active in this arable-farming département. Also cost the clean-up of any tanks or manure pits before renovation.
