In Marly, the benchmark price stands at 1 634 €/m² for an apartment. This level reflects an affordable market in the southern suburbs of Valenciennes, where the older red-brick fabric sits alongside more recent housing, a few minutes from the centre of the conurbation. These values come from DVF data, the French notarised sales database, meaning transactions actually registered with notaries, not estimates based on listings. They give an order of magnitude: each property still needs to be assessed according to its condition, location and floor area, as well as its proximity to tram stops and routes towards Valenciennes.

The Marly market is driven by its position in the inner ring of Valenciennes: the immediate proximity of the centre, the tram and the jobs of the conurbation supports steady demand, notably from first-time buyers drawn by affordable entry prices. The older brick stock, inherited from the municipality's working-class and industrial past, offers a volume of townhouses to renovate that find buyers, while the residential areas of detached houses meet family demand. Each sale remains sensitive to the specific characteristics of the property, condition, location and proximity to the tram, more than to any single market trend.
In the longer term, the price trajectory depends on several factors. Energy performance is becoming decisive: in an older stock, well-renovated homes gain value while poorly insulated properties sell at a discount, which weighs on part of the brick housing. The dynamism of Valenciennes Métropole, tram links and an affordable price level remain the underlying drivers of demand in this municipality of the Valenciennes area.
Marly sits in the lower range of its area: its prices remain below those of Valenciennes, while coming close to those of towns such as Douai or Cambrai.
Marly extends south of Valenciennes, in the Escaut valley, on a Hainaut territory crossed by the Rhonelle, a small river that joins the Escaut at Valenciennes. The name of the municipality appears in the forms Marlis, Marliz and Marliis from the 12th century, before settling as Marly in the 18th century. The Romans had already laid out several of their straight roads across this area, near a Valenciennes settlement oriented towards river navigation.
The history of Marly is marked by military episodes linked to Valenciennes: during the siege of 1793, the municipality saw the battle of Marly, on 26 May. In the 19th and 20th centuries, it became a working-class municipality of the Valenciennes basin, driven by industry and crafts. The Chimot brickworks, opened in 1904 with its Hoffmann kiln to supply the bricks for the Saint-Michel church in Valenciennes, operated until December 2024 and symbolises this heritage of brick and terracotta.
Today, Marly is a municipality in the southern suburbs of Valenciennes, part of the Valenciennes Métropole inter-municipal authority. It has nearly 12 000 inhabitants and is served by the Valenciennes tramway, whose lines T1 and T2 cross the town, notably with the La Briquette stop. This urban setting, close to the services and jobs of the conurbation, makes it a residential municipality sought after by households in the Valenciennes area.
According to INSEE, the French statistics institute, Marly has around 11 995 inhabitants, a stable population that has risen slightly in recent years. The market is aimed first at households from the Valenciennes basin: first-time buyers, families and working people looking for affordable housing in the immediate vicinity of the conurbation's centre and its jobs. The stock mixes brick townhouses, detached houses and apartments, which opens the market both to buying a main residence and to some buy-to-let investment, supported by moderate entry prices. Tram links and proximity to Valenciennes sustain steady demand for this kind of inner-ring municipality.
The benchmark price in Marly stands at 1 634 €/m² for an apartment. This figure comes from DVF data, the sales actually signed before notaries. It is an average: depending on floor area, condition and location, a brick townhouse needing renovation or a recent apartment close to the tram may differ appreciably from this base.
The surroundings of the centre and the streets near the tram stops are among the most in demand, for easy access to Valenciennes. The older red-brick buildings, typical of Hainaut, appeal to buyers fond of townhouses, while the more recent residential areas of detached houses attract families looking for a garden. Proximity to shops and schools remains a decisive criterion in the local market.
Marly is directly connected to Valenciennes by tram, whose lines T1 and T2 serve the municipality, for example at the La Briquette stop. The town is also linked by several bus lines of the conurbation and lies close to the main roads of the Valenciennes area. These links make commuting to the centre of Valenciennes and its employment area easier.
The local market mainly offers houses, from old brick townhouses to more recent detached houses with gardens. Apartments are available, notably in buildings near the centre and the tram, but remain more limited. For a first purchase or a tight budget, an apartment may be suitable; for a family looking for space, the detached house remains the dominant product in Marly.
As in any dense urban municipality of the conurbation, building rights are governed by the intermunicipal local urban development plan of Valenciennes Métropole. Part of the older building stock may require renovation work, particularly energy upgrades. Before any project, it is useful to consult the PLU, the local urban development plan, at the town hall to check the rules applicable to a plot and any easements.
