Atmospheric illustration of Castelginest, a municipality of the northern suburbs of Toulouse, in Haute-Garonne.
The average price recorded in Castelginest stands at 2 471 €/m². That level, affordable for the first ring around Toulouse, reflects the position of the municipality in the north of the conurbation, on the bank of the Hers-Mort. The average covers a stock in which the detached house dominates, inherited from the estates that accompanied the strong growth of the municipality since the 1970s, alongside more recent blocks of flats. Location, transport links to Toulouse, the condition of the property and its energy performance explain most of the gaps. These figures come from the DVF data, the French notarised sales database, which lists the transactions actually registered with notaries.

The Castelginest market rests on its position as a residential municipality in the north of the Toulouse conurbation, at prices that have stayed more affordable than in the central city or in the aeronautical municipalities to the west. Demand comes above all from families and first-time buyers looking for space and a garden without moving far from Toulouse. The very strong population growth of recent decades shows that appeal, with pressure bearing particularly on family houses and on building plots, which grow scarcer as the municipality becomes denser.
Membership of Toulouse Métropole and the closeness of the employment areas of the conurbation support steady demand, driven by households priced out of the most expensive districts. On the resale market, energy performance has become a marked negotiating criterion, especially on older detached homes whose certificate weighs in the price discussion. Road access and the quality of the living environment also count in the trade-offs. A correctly valued property stands out faster than one advertised too high.
In the north of the Toulouse conurbation, Castelginest shows prices more affordable than Toulouse and than its aeronautical neighbour Blagnac, in a range close to that of the adjoining municipality of Aucamville.
Castelginest lies about ten kilometres north of Toulouse, on the bank of the Hers-Mort, in the plain of the Toulouse area. Its name comes from the Occitan Castèl, the castle, and Genèsta, the broom shrub: literally the castle of the brooms. Medieval settlement took shape around the estate of Vilaigon, mentioned in the 10th century. The municipality appears for the first time in a charter in 1137. Like many villages of the Toulouse area, it was built in fired brick, the characteristic material of the region, around a church and fertile farmland.
In the 14th century, the building of a fort followed an agreement reached in 1368 between the village community and the abbot of Saint-Sernin in Toulouse, on whom the territory depended. Castelginest had earlier been part, in 1279, of a division into castellanies attached to Toulouse. For centuries the municipality remained a rural village living off farming, on the gentle land of the right bank of the Hers. That long agricultural period left few monumental traces, but it explains the scattered shape of the older housing, organised around farms and hamlets rather than around a dense centre.
The shift came from 1975 onwards, when Castelginest moved from a rural village of around 3 800 inhabitants to a residential town of the Toulouse suburbs. The population almost tripled in a few decades, carried by the immediate closeness of Toulouse and by the economic appeal of the conurbation. Now part of Toulouse Métropole, the municipality has been covered with housing estates while keeping a few farmed fringes. That recent development explains a spread-out town, made up above all of detached houses, where flats and shops were grafted on later along the roads towards Toulouse.
Castelginest has 11 271 inhabitants according to INSEE, the French statistics institute, after growth of more than 7 % since 2017. The housing stock is clearly one of detached homes: the house with a garden remains the dominant format, alongside more recent flats that have appeared along the main roads and near the shops. The municipality is marked by a high share of owner-occupiers, a common profile in the periurban municipalities of the first ring. Buyers are mostly families and working households from the Toulouse conurbation, looking for a greener setting and entry prices more affordable than in Toulouse itself, while staying connected to the central city.
The average value recorded from notarised sales is 2 471 €/m². That figure aggregates a recent apartment as much as an estate house with a garden, two different market realities. The type of property, its location within the municipality, transport links to Toulouse, the year of construction and energy performance explain most of the gaps around that average. For a reliable valuation, it is better to rely on comparable sales than on the municipal average alone.
The detached house largely dominates the Castelginest stock, inherited from the housing estates developed since 1975. It offers a garden and space, but buildings from the 1970s and 1980s often need energy renovation work. Apartments, which are rarer, are concentrated in recent blocks near the shops and the roads towards Toulouse, and suit first-time buyers. The choice depends mainly on your budget and on your need for outdoor space.
Castelginest lies about ten kilometres north of Toulouse. The municipality is linked to the central city by the roads of the northern conurbation and by the bus routes of the Tisséo network, which feed into the nearest metro stations. The car remains widely used for daily journeys, with the traffic constraints typical of the northern entrance to Toulouse at peak times. That closeness to the metropolitan area supports residential demand.
The municipality is drained by the Hers-Mort, which exposes some low-lying areas to flood risk. That information should be checked in the état des risques, the statutory natural-hazard disclosure, and in the planning documents before any purchase, as it can concern plots close to the river and to its tributaries. The local plan also sets out the building zones and the applicable rules. These points deserve to be examined case by case, according to the precise address of the property.
The municipality has developed in a spread-out way, without an inherited dense centre, which gives several residential atmospheres. The housing estates, in the majority, take up a wide share of the territory and offer houses with gardens. Around the roads towards Toulouse and the shops, more recent blocks of flats can be found. The fringes of the municipality keep a more open character, next to the farmed land of the Hers plain. These areas do not all sell at the same level.
