A farmhouse for sale in Isère (38), farmhouse built in the Dauphiné style of stone and timber, or a barn to convert with its hectares of pasture: this sharply contrasted department, spanning the Bièvre-Valloire plain and the Vercors and Trièves massifs, offers a range of farm buildings that shift with altitude. This page brings together the farmhouses, barns and mas for sale in Isère published on ma-propriete.fr: Trièves farms with a hay barn, Bièvre-Valloire farm complexes, former mountain farms with land and outbuildings.
Below you will find the actual prices of the Isère rural market, an overview of where to look, from the Bièvre plain to the Trièves, and the points to check before buying a former farm building. For a tourism project, 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 Isère (38) by type of municipality (cumulative sales from mid-2020 to 2025) and its change between 2021 and 2025.

On the Bièvre-Valloire plain, the Dauphiné farmhouse combines a pebble or stone dwelling with a barn-cowshed under tile or sheet metal, plus a more recent agricultural shed. At higher altitude, towards the Trièves and the Vercors, farms take on a more mountain character, with steeply pitched roofs and large timber-and-stone hay barns. There are no mas in Isère, a word reserved for the Mediterranean south of France.
These mountain or plain barns, often generously sized, lend themselves to conversion into a home or into gîtes, subject to the local planning zoning and altitude. The adjoining land, from a few hectares of hay meadow or pasture, can support livestock, horses or a permaculture project on valley floors.
The area around La Mure and the Trièves, near Mens, has a fairly wide choice of mountain farms and barns to renovate, in an unspoiled setting facing the Vercors. Towards Saint-Marcellin and the Bièvre-Valloire, farm complexes sit alongside orchards and lowland crops. The Bourgoin-Jallieu and northern Isère area has buildings closer to the Lyon employment area.
Near Grenoble and its basin, as well as in the Grésivaudan valley, renovated farm complexes are rare and expensive. Towards Vienne and the Rhône valley, demand is also strong, while the Trièves and the southern Vercors, more remote, remain noticeably more affordable.
Check the building's permitted use: in an agricultural zone under the local plan, a barn can only be converted into housing if it is listed among the buildings eligible for a change of use, which many mountain municipalities restrict strictly. Examine the roof (tile or sheet metal, but also asbestos-cement on some sheds), the timber frame, often sized for snow loads, and the drainage, sometimes complex in mountain terrain.
If land is included, ask about any current farm lease and about the pre-emption right of the Safer. Finally, cost the renovation precisely: utility access and winter road clearance can noticeably raise the cost of works at altitude.
