The Brétigny market is that of a residential outer-suburb commune well connected to Paris. With an average price of around 3 173 €/m² for an apartment and one hundred and forty-two sales a year, Brétigny-sur-Orge sits in the upper half of the Essonne communes on RER line C. The price loses 2 % over five years, with a high point in 2022 at 3 390 €/m² and a steady easing since.
What sets the commune apart lies elsewhere than in its geography of prices, which is simple: the new-build of the eco-district at the top, the older flats of the centre in the middle, the detached housing of the south at the bottom, with a 31 % gap end to end. It lies in the relationship between the two market segments: houses trade here at 3 153 €/m² and apartments at 3 173, a gap of 1 %. In every comparable commune that gap runs from 13 to 18 %. It means that the Brétigny square metre is worth the same whatever the property type, and that the trade-off between house and apartment is settled here on other criteria.
Brétigny-sur-Orge compared with the major French cities, on the average price per m² of an apartment.
Brétigny-sur-Orge lived two centuries on two activities that each left their mark on the fabric of the town. First the Clause seed company, established here for generations, whose name can still be read on avenue Lucien-Clause. Then air base 217, opened to the south-east of the commune and closed in 2012, whose memory is kept in the street names: Clément-Ader, Roland-Garros, Nungesser-et-Coli, Marcel-Dassault, Antoine-de-Saint-Exupéry, René-Leduc, colonel Rozanoff.
The land freed up by the seed company became the Clause-Bois Badeau eco-district, some two thousand four hundred homes built during the 2010s and 2020s in the north-west of the town, with its shops, its park and its avenues named after contemporary writers and scientists: Claude-Lévi-Strauss, Marguerite-Yourcenar, Simone-Veil, Georges-Charpak. It is today the most expensive sector of the commune.
The rest of Brétigny is detached housing, and its street names tell the story in series: tree species to the north in the villa district of La Fontaine, the provinces of France to the south towards La Moinerie and Maison Neuve, writers to the west towards Les Cendrennes. The town centre, around the RER line C station, the espace Jules-Verne and the Ciné 220 cinema, holds most of the older flats.
The Brétigny market has one feature that governs everything else: houses and apartments sell here at the same price per square metre, 3 153 against 3 173 euros. In comparable communes the gap runs from 13 to 18 %. In practice, the choice between the two comes down to the total budget, the plot and the running costs, not to the price per square metre. The commune attracts Paris region households looking to become owners thirty kilometres from Paris, with an RER train every fifteen minutes, and the Clause-Bois Badeau eco-district has added a large supply of new-build over the past ten years. Studios come out at 3 700 €/m² and T4 units and larger at 2 550: the gap between small and large floor areas stays within the norm for the outer suburbs.
The average price in Brétigny-sur-Orge is 3 173 €/m² for an apartment (actual DVF transactions, notarised sales), within a range of 2 588 to 3 695 €/m² depending on the district. Property portals show asking prices, 10 to 20 % above the prices actually recorded.
The gap is 31 % between the most expensive and the most affordable. Clause-Bois Badeau, the eco-district in the north-west, shows 3 469 €/m²; the town centre 3 067; La Moinerie, to the south, 2 633. The ranking is easy to read: new-build at the top, the older flats of the centre in the middle, the detached housing of the south at the bottom.
This is the particularity of the commune: both sell at the same price per square metre, 3 153 € for a house and 3 173 € for an apartment, a gap of 1 %. In comparable communes a house costs 13 to 18 % more. The choice therefore comes down to the total budget, the floor area, the plot and the running costs, not to the price per square metre.
Yes, by 9 % against the communal average and by 13 % against the town centre: 3 469 €/m² compared with 3 067. It is a new-build stock, put up during the 2010s and 2020s on the former land of the Clause seed company, with some two thousand four hundred homes. It records thirty-five apartment sales a year.
It is stable. The average price loses 2 % over five years and 3,7 % over the last twelve months, and the three districts ease back in the same proportions, between 1 and 3 % over five years. No sector is breaking away and none is running ahead.
Start with the year of construction: between the older flats of the centre and the new-build of the eco-district, the price gap reaches 13 %, and it comes from the building rather than the address. As houses and apartments sell at the same price per square metre, do not reason by property type but by total floor area and by plot. Then adjust for condition, energy performance and parking.
