Fontaine de l'Orme occupies the south-east of Saint-Michel-sur-Orge, around the rue Corot, the rue Watteau and the rue Fragonard, and the sports grounds that bear its name. The district grew out of a 1984 scheme that brought together 325 houses and 150 apartments in blocks, including a Castors-type self-build operation. The Jules-Verne school is in the district, and the Léonard-de-Vinci secondary school and the Mares-Yvon sports hall are nearby.
The district borders Villagexpo, a group of houses born of an exhibition-sale opened in 1966, the outcome of a competition launched in 1963 by the Ministry of Construction. Its 360 homes, around the rue de la Mare-des-Bordes and the rue de l'Île-de-France, welcomed their first residents in 1967. Since 2008, part of its houses have carried the Architecture contemporaine remarquable label. Villagexpo is an estate of houses and does not set the price of apartments in the district.
Fontaine de l'Orme stands at 2 523 €/m², 1 % below the town-wide average, with fourteen apartment sales a year. It is up 1 % over five years and 1,3 % over twelve months.
Fontaine de l'Orme is a residential district in the south-east of Saint-Michel-sur-Orge, with a price very close to the average, 2 523 €/m². It is made up of houses and small blocks of flats from the 1980s, linked by footpaths, with schools, a secondary school and sports facilities nearby. Buyers are families and first-time buyers looking for an apartment in a quiet area, and households aiming for a house in the district or in Villagexpo. Two points to examine. The range, from 2 086 to 3 048 €/m², is the widest in the town: depending on the residence, the floor and the condition, the difference in value is large, and a valuation by address is useful. And the price stability, 1 % over five years, from 2 488 €/m² in 2021 to 2 523 in 2026, rests on fourteen sales a year: the series peaked at 2 790 €/m² in 2022, and each year depends on a handful of transactions.
The average price in Fontaine de l'Orme is 2 523 €/m² for an apartment (actual DVF transactions, notarised sales), within a range of 2 086 to 3 048 €/m² depending on the building, the floor and the condition.

No. Villagexpo is a neighbouring estate of houses, born of an exhibition-sale opened in 1966 and lived in since 1967. Fontaine de l'Orme is a later scheme, from 1984, which mixes houses and small blocks of flats. The price of apartments in the district says nothing about the value of houses in Villagexpo.
Only slightly: the average price went from 2 488 €/m² in 2021 to 2 523 in 2026, a rise of 1 % over five years, and is up 1,3 % over twelve months. These figures rest on fourteen apartment sales a year and should be read with caution.
