Looking for a mill for sale in Haute-Garonne (31) means considering a department split between the Garonne valley, the Pyrenean foothills and the Lauragais, a wheat and woad plain once swept by the autan wind. It has former watermills along the Garonne, Save and Touch rivers, and a handful of rare windmills in the Lauragais, one of the last regions in France to still have them, recognisable landmarks of the local landscape rebuilt or preserved by heritage associations over recent decades. On this page, ma-propriete.fr brings together the mills for sale in Haute-Garonne: watermills to restore, former flour mills, Lauragais windmills or millers' houses with water rights.
You will also find price benchmarks based on actual sales, an overview of the areas where these properties are concentrated, and the specific points to check before buying a mill, whether a watermill or a windmill. To prepare your project, read our white paper on setting up a rural gîte, whose advice applies fully to a mill in Haute-Garonne, whether a watermill or a windmill, from renovation planning through to welcoming your first paying guests each season.
There are no official statistics dedicated to mills: sales are too rare and too varied (a ruin to restore, a habitable mill, a flour mill with a turbine). The most reliable market benchmark remains the price of country houses, which a habitable mill resembles, with a premium for the water, the character and the water rights, and a discount for the work required.

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 Haute-Garonne (31) 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 |
|---|---|---|---|---|
| Inland tourist areas (hinterland, mountains) | €164,580 | €1,690/m² | +0.6% | 650 |
| Peri-urban countryside (city catchment area) | €267,035 | €2,444/m² | +1.7% | 9,198 |
| Deep countryside (outside urban influence) | €169,200 | €1,549/m² | +2.1% | 2,552 |

The Garonne, between Saint-Gaudens and Toulouse, and its tributaries such as the Save, the Touch and the Hers-Mort, powered numerous watermills, often tied to grain growing on the Toulouse plain, one of the historic breadbaskets of south-west France. The Canal de Garonne and the Canal du Midi, legacies of the great 17th-century hydraulic works, also feature a few notable mills and locks, notably around Montech and Négrepelisse, remnants of a now-listed waterway heritage that still draws boating tourists and cyclists along the towpath today.
The Lauragais, in the east of the department near Revel and Villefranche-de-Lauragais, is autan-wind country: it is one of the few regions in France where stone windmills survive, a legacy of a grain plain almost devoid of powerful watercourses and long specialised in growing woad, the plant behind the region's historic blue-dye trade and considerable wealth. To the south, near Saint-Gaudens, Pyrenean rivers favoured small mountain watermills instead, more modest but well preserved thanks to the region's slower pace of development.
The Save and Touch valleys, west of Toulouse, offer the best balance between rural heritage and access to the metropolis and its TGV station. The Lauragais, around Revel and Villefranche-de-Lauragais, is the natural destination for a windmill or a former plain flour mill, in a landscape of gentle hills and sunflower fields, grown here for generations. Near Saint-Gaudens, at the foot of the Pyrenees, mountain mills sit in a steeper setting with views of the peaks.
Properties near Toulouse and its immediate surroundings are clearly above the department average, driven by the aerospace metropolis's economic momentum. The Lauragais and the Comminges area around Saint-Gaudens, further from the metropolis, remain more affordable for a mill to restore, with longer commuting times to Toulouse and its job centres, offset by lower prices per square metre.
For a watermill, check the water rights, the condition of the millrace and sluice gates, and the ecological-continuity obligations that apply notably on the Garonne and its tributaries classified for Atlantic salmon. For a Lauragais windmill, the main concern is the stability of the stone tower and the condition of the timber frame and machinery, often incomplete after decades of disuse and partial dismantling, sometimes to reclaim stone or timber for other local buildings.
The building, in foraine brick around Toulouse or limestone in the Lauragais, needs a check on damp and on flood zoning for valley mills, particularly near the Garonne and its main tributaries. Outbuildings lend themselves to a gîte project, a growing activity in the Lauragais and Comminges, gateways to the Pyrenees.
