The 2026 figures· Indicative data
4 276€/m²

The average price recorded in Le Pecq stands at 4 276 €/m². That average covers a stock made up mainly of flats, where older buildings in the centre sit alongside developments of the 1960s and 1970s and more recent schemes near the Seine. The municipality also keeps a distinct stock of detached housing: Belle Époque villas and holiday houses clinging to the slopes that rise towards Saint-Germain-en-Laye. Those houses, rarer on the market, trade at a markedly higher level, at around 6 321 €/m², which owes to their floor area, their plot and often their view over the river. The figures come from the DVF database, which records the transactions actually registered before notaries.

Market trends and analysis for Le Pecq

The Le Pecq market rests first of all on its position in the loop of Saint-Germain-en-Laye, by the Seine and on Line A of the RER. The municipality captures demand from families and managers who are aiming for western Paris but find Saint-Germain-en-Laye or Le Vésinet out of reach. That position as a more affordable option, in an equivalent setting, supports family apartments and houses with outdoor space. The scarcity of detached housing in the neighbouring municipalities reinforces interest in the houses of Le Pecq.

Supply remains constrained by the small size of the territory and by its already very built-up nature, between the two banks and the island. Riverside properties and those with a view pull values upwards, while the stock of flats from the 1960s and 1970s weighs on the average. As everywhere in the Île-de-France, energy performance has become a bargaining point, in particular on older buildings and on large houses in need of renovation. The closeness of Saint-Germain-en-Laye continues to serve as a price benchmark for the whole loop.

The history of Le Pecq

Le Pecq is one of the few municipalities built on both banks of a river, alongside Paris and Rouen. Set in a loop of the Seine some twenty kilometres west of Paris, at the foot of the château of Saint-Germain-en-Laye, it also takes in the île Corbière, partly protected as a nesting area. Its name appears as early as 704 in the form Aupec, in a Merovingian charter of King Childebert III linking the territory to an abbey. In 1875, part of the municipality broke away to form Le Vésinet.

Le Pecq played a particular part in the history of the railway. In 1837, it was the terminus of the first French railway line reserved for passengers, opened from Paris. The locomotives of the day could not climb the slope leading up to Saint-Germain-en-Laye: trains therefore stopped by the Seine, at Le Pecq, before the line was extended a few years later by a viaduct crossing the two arms of the river. That arrival of the railway fixed the residential vocation of the municipality very early on.

In the 19th century the banks of the Seine drew painters who came to work the light of the river, in the wake of the impressionists, and a themed path keeps the memory of it today. The built heritage mixes the church of Saint-Wandrille, put up in 1739 and topped with a triangular pediment, and the church of Saint-Thibault, built in 1964, recognisable by its wooden spire some thirty metres high. That legacy can still be read in the fabric of villas and grand houses that lines the river and climbs towards the slopes.

Who buys in Le Pecq

Le Pecq brings together a little more than 16 059 inhabitants on a tight territory shared between the two banks of the Seine. The stock mixes apartments, in the majority, with a sizeable share of detached houses inherited from the 19th century holiday tradition and from the 20th century building estates. Buyers are mainly Paris-region families looking for a waterside setting and quick access to Paris and La Défense, managers working in western Paris, and households already settled in the loop of Saint-Germain who want to stay there. The immediate closeness of Saint-Germain-en-Laye and Le Vésinet, both dearer, steers towards Le Pecq a demand that seeks the same quality of life on a more measured budget.

Frequently asked questions

The municipal average comes out at 4 276 €/m², calculated from the sales registered before notaries and published in the DVF database. That figure covers very varied situations, from an older apartment in the centre to a house on the slopes. The address, the bank of the river, the storey, the view over the Seine, the year of construction and the energy performance certificate explain most of the gaps. For your property, a valuation based on comparable sales will always be more accurate than the average alone.

What makes Le Pecq unusual is that it occupies both banks of the Seine. The riverside, with its grand houses and its recent developments, offers the most open views. The slopes rising towards Saint-Germain-en-Laye concentrate villas and a more well-to-do housing stock. The Ermitage district and the old centre show a more mixed fabric. These settings do not sell at the same level, and closeness to the station also weighs on values.

Le Pecq relies on Line A of the RER, whose Le Vésinet-Le Pecq station serves the municipality directly, while the Saint-Germain-en-Laye terminus is very close. La Défense is reached in around twenty minutes, and the centre of Paris, as far as Châtelet-Les Halles, in about thirty. Several bus routes complete the links to the neighbouring municipalities. That quick access to western Paris is one of the springs of local demand.

Yes, the municipality has kept a real stock of detached housing, which sets it apart from neighbouring towns that have become very largely made up of flats. The houses are found mainly on the slopes and along the Seine, from Belle Époque villas to estate-built houses. They trade at a level above that of apartments, at around 6 321 €/m², depending on their plot, their condition and their view. Properties of that kind remain sought after and often go quickly.

Its position by the Seine means checking exposure to flood risk before any purchase, in particular for properties close to the river and on the île Corbière. That information appears in the planning documents and in the statement of risks given to the buyer. As across the whole Paris conurbation, letting a furnished tourist rental is also regulated. These points are checked in advance, with the help of the town hall if needed.
