The 2026 figures· Indicative data
3 684€/m²

The average price of apartments in Saint-Jean-d'Illac stands at 3 684 €/m², based on the DVF transactions actually registered with notaries. An extensive municipality of Gironde located some fifteen kilometres west of Bordeaux, Saint-Jean-d'Illac rests on a vast wooded territory, on the edge of the Landes forest and its pines. The built fabric remains overwhelmingly made up of detached houses, with a limited share of apartment blocks. Demand comes above all from working households of the Bordeaux metropolitan area looking for a green setting, more open than in the city centre, while staying connected to the employment area. The value of a property depends on how close it is to the roads towards Bordeaux, on the size and the aspect of the plot, on its general condition and on the presence of outdoor space.

Market trends and analysis for Saint-Jean-d'Illac

The Saint-Jean-d'Illac market remains supported by the land pressure of the Bordeaux conurbation. The scarcity of large plots available and the appeal of detached housing in contact with the forest sustain demand, in particular from families leaving Bordeaux or its inner ring. Well-located properties, close to the main roads and to services, sell faster than outlying homes or those needing works.

The appeal lies in the wooded setting, the available floor space and the closeness of the Bordeaux employment area, through Mérignac in particular. The limits lie in the reliance on the car for the areas far from the centre, in the extent of the municipality, which creates widely varying situations, and in the sensitivity of the market to lending conditions, which weigh on the purchasing power of buyers.

The history of Saint-Jean-d'Illac

Long tied to the stretches of heathland and forest west of Bordeaux, Saint-Jean-d'Illac was first a rural territory, shaped by the working of pine and of the wooded spaces that still cover a large part of the municipality.

Development picked up with the spread of the Bordeaux conurbation and the arrival of working households wanting to settle away from the city, in a wooded environment. The closeness of business parks and of the Bordeaux-Léognan airfield went with this change.

Today, Saint-Jean-d'Illac has 9 616 inhabitants and stands out as a residential municipality of western Gironde, carried by the land pressure of the metropolitan area and by the appeal of detached housing in contact with the forest.

Who buys in Saint-Jean-d'Illac

With 9 616 inhabitants, Saint-Jean-d'Illac has a housing stock dominated by the detached house, on plots that are often generous on the edge of the forest. Apartments are fewer there and mainly concern the areas closest to services. Buyers are for the most part families and working households employed in the Bordeaux conurbation, in Mérignac or in the neighbouring employment areas, drawn by the wooded setting, the available floor space and a reasonable distance from Bordeaux. This sustained demand explains a tight market for a municipality of this size, sensitive to the quality of the location and to access to the main roads.

Frequently asked questions

The average price of apartments in Saint-Jean-d'Illac is 3 684 €/m², based on the DVF transactions actually completed before notaries. This average level covers gaps that depend on the location, on the closeness of the roads towards Bordeaux, on the condition of the property and on the presence of outdoor space.

Yes. The housing stock is dominated by the detached house on often large plots, on the edge of the forest. Apartments remain in the minority and are concentrated near services, which gives the market a distinctly residential orientation.

The location weighs heavily: the closeness of the roads towards Bordeaux and of the shops, the size and the aspect of the plot, the general condition, the energy performance rating and the presence of a garden or a garage account for most of the gap in value.

The municipality offers a wooded setting and floor space at a reasonable distance from Bordeaux and from Mérignac. This balance between a green environment and access to the Bordeaux employment area attracts families and working households of the metropolitan area.
