A farmhouse for sale in Loire-Atlantique (44), a Nantes-area farm building or a Pays de Retz tenant farm: between estuary, marshland and vineyard, the department keeps a varied set of farm buildings that are now sought after for conversion. This page brings together the farmhouses, barns and mas for sale in Loire-Atlantique published on ma-propriete.fr: a Pays de Retz farm with outbuildings, a Nantes-vineyard barn to renovate, a Brière-marsh farm building, a former holding with a cowshed and shed. Proximity to the coast, to Nantes and the presence of appellation vines are among the criteria that most set listings apart from one another.
Below you will find the actual prices of the Loire-Atlantique rural market, an overview of where to look, from Pays de Retz to the Châteaubriant area, 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. Local agents and notaries are familiar with files combining older buildings and protected wetlands.
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 Loire-Atlantique (44) by type of municipality (cumulative sales from mid-2020 to 2025) and its change between 2021 and 2025.
| Type of municipality | Median price 2020-2025 | Median price per m² | Change 2021-2025 | Sales 2020-2025 |
|---|---|---|---|---|
| Tourist coastline | €330,000 | €3,508/m² | +3.7% | 800 |
| Residential coastline | €245,000 | €2,453/m² | +0.8% | 1,807 |
| Peri-urban countryside (city catchment area) | €245,000 | €2,374/m² | +0.0% | 11,176 |
| Deep countryside (outside urban influence) | €185,000 | €1,852/m² | +8.6% | 4,771 |

The traditional farm building of Loire-Atlantique, often called a métairie, pairs a low dwelling built of tuffeau stone or granite with a cowshed and a barn arranged in a row or an L-shape around a courtyard. In the Brière marsh, buildings stand out for their thatched roofs and earth walls, an architecture unique in France linked to reed harvesting. Mas and bastide are absent from the local landscape, those names staying specific to the south of France.
Barns in the Nantes vineyard and Pays de Retz, often modest in size, convert into a home or gîtes subject to an approved change of use. The adjoining farmland, from a few hectares of vines to damp pasture, suits keeping horses in some areas or, on lighter soils, a permaculture project. Some tenant farms still have a well and a bread oven, elements of a still clearly identifiable rural heritage.
In the Pays de Retz, around Machecoul and Legé, and towards Ancenis and the Nantes vineyard, the choice of farms and barns to renovate remains the widest and most affordable in the department. The Châteaubriant area, near the Maine-et-Loire border, also offers older buildings at contained price levels.
Near Nantes and along the Loire, renovated farm buildings are scarce and trade clearly above the departmental average. On the coast, between Pornic and Guérande, and around the Brière marsh, thatched cottages and former tenant farms form a particularly sought-after niche market. Between the two, the Vallet area and the Muscadet vineyard form an intermediate zone, between wine growing and traditional mixed farming.
Check the building's permitted use: in an agricultural zoning area, a barn can only become a home if it is identified as eligible for a change of use. Check the roof (tile, thatch in Brière requiring specific upkeep, or asbestos-cement sheets on more recent farm sheds), the timber frame and the drainage, which needs careful checking on plots near marshes and wetlands. An asbestos survey and a check on the state of the foundations are recommended before buying in an area close to the marshes.
If farmland comes with the property, ask about any current farm lease, particularly for vines in the Nantes vineyard, and the pre-emption right of the Safer. Finally, cost the renovation precisely, which can be expensive for a thatched Brière cottage.
On ma-propriete.fr, filter Loire-Atlantique farms and barns by budget, built area and land area, set up an email alert to be told of new listings, and extend your search to all farmhouses, barns and mas for sale in Pays de la Loire. It is also worth comparing whether vines, pasture or wetland are attached, a criterion that strongly shapes the feasible farming project.
