In Élancourt, the average price of apartments stands at 2 825 €/m², based on the DVF data, that is, on sales actually registered before notaries. That average covers a stock built for the most part over some twenty years, between 1970 and 1990, at the time of the new town: apartment developments of Les Sept-Mares and the plateau, terraced town houses, housing developments of La Villedieu and the north of the commune. The gaps owe above all to the health of the block's management, to the condition of the common parts of these 1970s estates and to the distance from La Verrière station.

Demographics are the first driver of the Élancourt market. After very rapid growth in the 1970s, the population reached a high point of around 27 600 inhabitants in the mid-2000s, before falling back to 26 365 inhabitants. The number of people per dwelling has fallen from 3,29 in 1968 to 2,30 today, and 38,2 % of households are now single-person, according to INSEE. That loosening feeds a steady turnover: ageing households free up houses and large apartments bought when the schemes were delivered, which families take over.
The second driver is employment and road access. The commune hosts 517 active businesses at the end of 2024, and the Clef-de-Saint-Pierre area concentrates more than 8 000 jobs with sites of Thales and Airbus Defence and Space. At the same time, 81,5 % of working residents are employed outside the commune, which makes access via the A12, the RN10 and La Verrière station decisive in choosing a sector. With around 203 transactions a year, the market stays liquid and provides stable price markers.
Élancourt sits in the lower part of this group of Yvelines communes. Its price level stays appreciably below that of Louveciennes and Saint-Nom-la-Bretèche, and well behind Versailles.
The name Élancourt combines the suffix -court, a marker of early medieval rural foundations, with the Germanic personal name Agilenus. The place appears as early as the 9th century in the polyptych of Irminon, an inventory of the lands of the abbey of Saint-Germain-des-Prés. The territory then consisted of the village grouped around the Saint-Médard church, of Romanesque origin, and of scattered hamlets: Launay, La Grande and La Petite Villedieu, Les Coudrays, recorded from the 16th century. At La Villedieu, the Templars founded a commandery around 1180, whose buildings survive and have been restored. Until the 1960s, Élancourt remained a farming commune of fewer than a thousand inhabitants: 861 at the 1968 census.
The turning point was the new towns policy. Élancourt was attached in 1971 to the perimeter of Saint-Quentin-en-Yvelines, whose development was led by the team of Serge Goldberg. The Sept-Mares district was designed to serve as the centre of the western part of the new conurbation: it brings together the town hall, the library, the cinema, the shops and the administrative facilities. Construction was rapid and concentrated. The population went from 861 inhabitants in 1968 to 10 629 in 1975, then to around 15 000 in 1978. That compressed timetable explains the uniformity of the present stock, a large part of which was built in some fifteen years with the same construction methods.
The withdrawal of Plaisir from the new town authority, in 1983, redirected development towards the north of Élancourt. The Clef-de-Saint-Pierre business park, created in 1990 across Élancourt and Trappes, today brings together around a hundred companies over some 160 hectares and more than 8 000 jobs, with sites of Thales and Airbus Defence and Space. In May 1991 the France Miniature park opened, reproducing French landmarks at 1/30th scale. To the south, the Élancourt hill, formed by dumping spoil from the new town's building sites, reached 231 metres in 1992 and became the highest point of the Paris region; it hosted the Olympic mountain bike events on 28 and 29 July 2024.
Élancourt has 26 365 inhabitants and 12 100 dwellings, of which 94,2 % are main residences and 1,2 % second or occasional homes, according to INSEE, the French national statistics institute. The stock brings together 66,3 % apartments and 32,4 % houses, a balance more favourable to single-family housing than in many communes born of the new town. Again according to INSEE, 64 % of households own their main residence and 34,8 % rent, for an average household size of 2,30 people. Buyers are mainly families and working households of the Saint-Quentin-en-Yvelines employment area, along with owners already settled who change home without leaving the commune.
The average price of apartments in Élancourt stands at 2 825 €/m², calculated on DVF sales actually completed before notaries, for a volume on the order of 203 sales a year. That town-wide average covers appreciable gaps depending on the sector, the year of construction and the quality of the block's management. A given property can therefore sit clearly above or below that marker.
The commune reads as three parts: the old village around the Saint-Médard church, the plateau built up in the 1970s with the Sept-Mares centre, and the northern part developed after 1983 around La Clef-de-Saint-Pierre. The houses of the village and the individual developments of La Villedieu generally trade above the town-wide average, while the large blocks of the plateau sit rather in the lower part of the market.
Élancourt has no station on its territory. The nearest is La Verrière, about 1,4 kilometres away, served by Transilien line N towards Paris-Montparnasse in around forty minutes and by line U towards La Défense in around thirty. Trappes station is also reachable. The Saint-Quentin-en-Yvelines bus network covers the commune, and the A12 motorway and the RN10 provide the road links.
Yes, and in a notable proportion for a new town commune: 32,4 % of the stock is made up of houses, against 66,3 % apartments, according to INSEE. These are mainly terraced town houses and detached homes delivered with the schemes of the 1970s and 1980s, around the village, La Villedieu and Les Coudrays. This segment turns over little, owner-occupiers being in the majority in the commune.
Most of the stock was built between 1970 and 1990, often in large blocks under joint ownership. Before buying or selling, it is worth looking at the energy performance certificate, the condition of the windows and insulation, and the works voted at general meetings, notably on facades and heating. These elements now weigh more on the value of an apartment than floor area alone, and explain part of the price gaps from one block to another.
