Bois des Roches occupies the east of Saint-Michel-sur-Orge, around the wood of the same name, planted with century-old oaks and a remnant of the former forest of Séquigny. The land, bought before the war by Victor Robin, hosted a project launched in 1961 for around 2 600 apartments in blocks and 50 houses. Construction began in 1964, half of the homes were occupied by 1967 and the shopping centre opened in 1968; the Les Genêts residence followed in 1981.
The district is organised around the allée Massenet, the rue Lecocq and the rue Messager, where the Domaine du Bois des Roches groups 980 co-owned apartments, and around the place Marcel-Carné and the venue of the same name, which houses a three-screen cinema classed Art et Essai and a performance hall. It also includes the Grand Bois shopping centre, the Bellevue residence and shopping centre on the avenue de Brétigny, the Lamartine school and, to the west towards the station, recent developments around the mail Gambetta. The priority urban neighbourhood defined in 2015 was called "Le Bois des Roches"; the one in the 2024 priority map, "L'entre bois des roches", has 1 771 residents on 18 hectares. Under Action Cœur de Ville, the place Marcel-Carné has been undergoing works since late 2024, with 1 400 m² of green space planned.
Bois des Roches stands at 2 466 €/m², the most affordable price in Saint-Michel-sur-Orge, 4 % below the town-wide average, with 31 apartment sales a year. It is up 10 % over five years and 18,9 % over twelve months.
Bois des Roches is one of the two centres of Saint-Michel-sur-Orge, with its shops, cinema, schools and wood, and the most affordable district in the town, at 2 466 €/m². It is worth knowing what this price describes. It mixes two markets: the co-owned blocks of the 1960s post-war housing estate, including the Domaine du Bois des Roches, which sell well below it, and recent developments on the station side, around the mail Gambetta, which pull the average up. An apartment in the estate therefore does not sell at the district's average price. Buyers are first-time buyers and families looking for a large floor area on a limited budget, working people drawn by the station on the west side, and investors. Two points to examine. The range, from 1 989 to 2 763 €/m², depends first on the residence: compare a property with sales in the same building, and look at service charges, works already voted and energy performance. And the 18,9 % rise over twelve months follows a low of 2 199 €/m² in 2024: it rests on 31 sales a year, whose split between the estate and the station side varies from year to year, and needs confirming. The 10 % rise over five years, from 2 236 €/m² in 2021 to 2 466 in 2026, gives a more reliable reading.
The average price in Bois des Roches is 2 466 €/m² for an apartment (actual DVF transactions, notarised sales), within a range of 1 989 to 2 763 €/m² depending on the building, the floor and the condition.
The east of Saint-Michel-sur-Orge, around the bois des Roches: the 1960s post-war housing estate, including the Domaine du Bois des Roches on the rue Messager, the Grand Bois shopping centre, the place and the venue Marcel-Carné, the Bellevue residence on the avenue de Brétigny, and, to the west towards the station, recent developments around the mail Gambetta.
No. The price of 2 466 €/m² mixes the co-owned blocks of the estate, which sell well below it, and more expensive recent developments on the station side, which pull the average up. For an apartment in the Domaine du Bois des Roches, only a valuation at the address gives a reliable order of magnitude.
Yes, by 10 % over five years, from 2 236 €/m² in 2021 to 2 466 in 2026. The 18,9 % rise over twelve months follows a low in 2024 and rests on 31 sales a year, whose split between the estate and the station side varies: it should be read with caution.
