A farmhouse for sale in Val-d'Oise (95), a barn to convert or a smallholding with a few hectares: the French Vexin and the Pays de France, in the north of the department, still have a strong stock of limestone and millstone-grit farm buildings despite the proximity of Paris. This page brings together the farmhouses, barns and mas for sale in Val-d'Oise published on ma-propriete.fr: a square-plan farm with a barn and stables, a former Vexin farm building awaiting renovation, a smallholding with pasture for horses.
Below you will find the actual prices of the Val-d'Oise rural market, an overview of where to look, from the French Vexin to the Pays de France, 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 Val-d'Oise (95) 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 |
|---|---|---|---|---|
| Peri-urban countryside (city catchment area) | €343,000 | €3,068/m² | -4.9% | 1,702 |

In the French Vexin, the square-plan farmhouse dominates: the house, barn, cowshed and shed arranged around a courtyard closed by a massive porch, all built in the cream-coloured limestone typical of the plateau. In the Pays de France, in the east of the department, farm complexes are more elongated, often L-shaped, with later brick outbuildings. The mas has no local reality in Val-d'Oise, the term being reserved for southern France.
These buildings, sometimes considerable in size on the Vexin plateau, convert well into a family home with workshop space or into several gîtes, subject to planning zoning and a building permit. The adjoining land, often still-farmed farmland, can run to several hectares, suitable for pasture for horses or a permaculture project.
In the French Vexin, around Magny-en-Vexin, Marines and Vigny, the choice of farmhouses and barns to renovate is the widest in the department, within a farming plateau classed as a regional nature park. Towards L'Isle-Adam and the Oise valley, farm complexes sit alongside more urban second homes. To the east, around Louvres and Survilliers, in the Pays de France, Picardy-style farm buildings remain accessible despite the proximity of Roissy airport.
Areas served by the Persan-Beaumont railway station or close to Pontoise stay clearly above the department average, while the heart of the Vexin, further from stations, offers more affordable prices for comparable agricultural volumes.
Check the permitted use of the buildings against the local plan: a barn classed in an agricultural zone can only be converted into a home if a change of use has been explicitly authorised, which remains strict within the French Vexin regional nature park. Check the roof (flat tile or asbestos-cement sheets on sheds), the timber frame and the drainage.
If land is included, ask about any current farm lease, common on the arable Vexin plateau, and about the pre-emption right of the Safer. Cost the renovation precisely: restoring a large limestone barn is often a budget comparable to the purchase price.
