The average price recorded in Marly-le-Roi stands at 3 766 €/m² for an apartment. That average covers a housing stock dominated by flats: according to INSEE, the French national statistics institute, 79,5 % of the municipality's dwellings are apartments, most of them from the post-war schemes, starting with the Grandes Terres estate. Houses, in the minority, trade at around 6 259 €/m², above all in the old village and on the slopes near the park. These values come from DVF data, which records the transactions actually registered before notaries, and not from the prices shown in listings.

The Marly-le-Roi market is held first of all by its shortage of land and by its setting. Between the national estate, the state forest and the protected perimeters of the old village, the municipality has little building land across its 6,54 square kilometres. Sales volumes therefore stay steady from one year to the next, at around 161 transactions a year, without the jolts produced by deliveries of new schemes elsewhere in the Yvelines. Demand comes above all from families settled in Paris or in the Hauts-de-Seine, looking for floor space and direct access to the forest.
The structure of the stock explains the second movement. A large share of the apartments comes from the Grandes Terres estate and from the schemes of the 1950s and 1960s, now at the age of heavy works, energy works in particular. Renovated homes stand clearly apart from those that are not, and that gap has widened with the tightening of the rules applying to the least efficient dwellings. Conversely, the house segment, rare and concentrated in the old village and on the slopes, serves as a ceiling for the market and remains little sensitive to swings in volume.
Marly-le-Roi sits in the lower range of the municipalities of the loop, close to the level of Louveciennes but clearly below the addresses on the right bank. The three municipalities below frame its price level.
The place is recorded as early as 676, under the reign of Thierry III, in a Latin form derived from the name of a Gallo-Roman landowner. The suffix le Roi recalls its attachment to the royal domain. Everything changed in 1676, when Louis XIV acquired the lordship and entrusted Jules Hardouin-Mansart with the building of a château conceived as a retreat more intimate than Versailles: a royal pavilion surrounded by twelve pavilions for guests, at the end of a water vista. To feed those gardens and those of Versailles, the machine de Marly was raised on the Seine in the 1680s by Arnold de Ville and Rennequin Sualem, with fourteen paddle wheels and an aqueduct crossing Louveciennes.
The horse pond, laid out between 1698 and 1702 at the foot of the park, completes the ensemble and remains the largest work of its kind in Europe. The revolutionary years put an end to that setting: the estate was looted in 1789, then sold. In 1799, the industrialist Alexandre Sagniel bought the abandoned château, took it apart and sold on its stones as building material. All that survives today are the terraces, the basins and the layout of the gardens. The estate passed to the Eaux et Forêts administration in 1806. The machine, whose output had collapsed, was destroyed in 1817 and replaced by successive installations.
The opening up came from the railway. After a steam tramway brought into service in 1878, the Marly-le-Roi station opened on 5 May 1884 on the line from Saint-Cloud to Saint-Nom-la-Bretèche, 25,9 kilometres from Paris-Saint-Lazare: the municipality then entered the residential orbit of the capital. The real demographic turning point came later. Between 1957 and 1961, the architects Marcel Lods and Jean-Jacques Honegger built the Grandes Terres estate, around 1 500 dwellings laid out in squares on a landscaped promontory. That scheme, given the Architecture contemporaine remarquable label, explains on its own the present shape of the town: a municipality of flats set against a historic estate and the forest.
The town of today lives on that double inheritance. The national estate of Marly, run by the State, and the neighbouring state forest, of around 2 000 hectares, take up most of the 6,54 square kilometres of municipal territory and lastingly cap the spread of building. The museum of the Domaine royal, set in the park, keeps models, sculptures and original elements of the vanished château. The municipality ranges between 48 and 179 metres in altitude, from the banks of the Seine to the wooded plateaux, which creates very marked differences of view and aspect from one district to another, and weighs concretely on property values.
Marly-le-Roi has 16 756 inhabitants for around 7 700 households. According to INSEE, the municipality counts nearly 8 300 dwellings, of which 91,9 % are main residences and only 1,7 % second homes: the market is carried by buyers who come to live there, not by a holiday clientele. Again according to INSEE, 79,5 % of dwellings are apartments, and 67,2 % of main residences are occupied by their owner against 31,5 % by tenants. The dominant profile is that of working families employed in Paris, at La Défense or in Versailles, looking for a family apartment in a wooded setting, for want of houses available in any number.
The average price in Marly-le-Roi comes out at 3 766 €/m² for an apartment, on the basis of the DVF transactions registered before notaries. That figure is a municipal average: it aggregates the large co-ownerships of the 1950s and 1960s, more recent developments and a few older addresses in the old village. For a specific property, the gap with that average depends above all on the view, the storey, the general condition and the distance to the station.
The highest values are found in the old village, around the church of Saint-Vigor and the edges of the park, where the older houses and the narrow streets listed within the protected perimeter are concentrated. The slopes facing the Seine valley and the addresses on the forest edge follow. The Grandes Terres estate, overwhelmingly flatted, forms the base of the market and sits closer to the municipal average.
The two markets are clearly separate. The apartment largely dominates the stock, with 79,5 % of dwellings according to INSEE, and concentrates most of the annual sales. The house remains rare and trades at around 6 259 €/m², a gap of about 66 % with the apartment. A house budget in Marly-le-Roi therefore compares more with the neighbouring municipalities of the Seine loop than with the local apartment market.
The municipality is not served by the RER. The Marly-le-Roi station, opened in 1884, is on Line L of the Transilien, 25,9 kilometres from Paris-Saint-Lazare, via Saint-Cloud. The Grandes Terres and the old village are at uneven walking distance from that station, which creates a price hierarchy visible within the municipality. By car, the A13 and the A14 serve La Défense and the west of Paris.
Yes, and lastingly. The national estate of Marly and the state forest cover a large part of the municipal territory, which is only 6,54 square kilometres. A procedure to list the Marly massif as a protection forest has been started by the State, a status that makes urbanisation almost impossible on the areas concerned. In practice, new supply comes above all through the renovation and densification of the existing buildings.
