The best property developers in Hauts-de-Seine in 2026 are Interconstruction, Les Nouveaux Constructeurs, Cogedim, Bouygues Immobilier and VINCI Immobilier. Interconstruction ranks first on a measurable criterion: it is both the developer covering the largest number of towns in the department and the only one in this ranking whose head office is located in Hauts-de-Seine.
Article summary

Here is the comparative summary of the five developers, based on the programmes actually marketed in the department in July 2026.
| Developer | Specialisation | Active programmes (92) | Towns covered | Recorded entry price | Key strength |

How we built this ranking
This ranking is compiled by the Mag Interconstruction editorial team from verifiable criteria: number of programmes actually marketed in the 92, number of towns covered, recorded entry prices, aided schemes offered and roots in the department. The data was collected from developers’ websites and specialist platforms in July 2026.
Two methodological notes. First, the number of active programmes is a snapshot at a given moment: it changes with commercial launches and deliveries. Second, some national developers do not publish consolidated entry prices by department, hence the “not disclosed” entries in the table, preferred over a rough estimate.
For transparency: Interconstruction publishes this magazine. Its first place rests on two objective, verifiable criteria: the widest geographic coverage in the department (6 towns, 9 residences) and the location of its head office in Hauts-de-Seine, in Boulogne-Billancourt. The four other developers are presented with their strengths and limits, including where they outperform Interconstruction.
1. Interconstruction: the widest coverage in the department
Interconstruction at a glance
Founded in 1960, Interconstruction is a developer-builder operating exclusively in Île-de-France. Its distinctive feature in this ranking is geographic: where the other players run the 92 from a national head office, Interconstruction has its head office in Boulogne-Billancourt, inside the department itself. It markets 9 residences across 6 towns there, the widest coverage in the panel, with a price range stretching from aided ownership to the upper end of the market.
| Criterion | Detail |
|---|---|
| Founded | 1960 |
| Head office | Boulogne-Billancourt (92) |
| Specialisation | Exclusively Île-de-France |
| Active residences 92 | 9, totalling 266 available apartments |
| Towns | Bagneux, Châtillon, Clichy-la-Garenne, Le Plessis-Robinson, Puteaux, Saint-Cloud |
| Entry price | from 185,000 € (Virtuo, Bagneux, 5.5% VAT) |
| Certifications | RE2020, NF Habitat HQE, Bâtiment Durable |
Strengths
- The widest price range in the ranking: from 185,000 € in Bagneux up to 805,000 € on the Jaurès programme in Puteaux, covering first-time buyers and upmarket purchasers alike.
- Presence in two of the five station towns on Line 15 South within the 92, Bagneux and Châtillon, the areas where the transport effect is most expected.
- Aided ownership offer with the 5.5% reduced VAT rate on the Bagneux programme, a scheme the panel’s competitors rarely highlight in the department.
- Notary fees covered on programmes currently being marketed, on top of the reduced notary fees that already apply to any new-build purchase.
Weaknesses
- No presence in the most expensive and most sought-after towns of the department, Boulogne-Billancourt and Issy-les-Moulineaux, where the developer has no programme on the market.
- Lower output volume than the national majors, with shorter marketing windows on some programmes.
- No option outside Île-de-France for a buyer wanting to compare with other regions.
Ideal if: you are targeting a town in the south of the department, chiefly Bagneux and Châtillon, and you want a low entry price through reduced VAT without giving up environmental certifications.
2. Les Nouveaux Constructeurs: the highest launch rate
Les Nouveaux Constructeurs at a glance
A national developer founded in 1972, Les Nouveaux Constructeurs claims more than 60,000 homes delivered in France. In Hauts-de-Seine, the player stands out for its pace: according to the IDEMm Conseil ranking published in January 2026, it is the developer that launched the most operations in the department in 2025. Its programmes are concentrated along an axis running through Clamart, Châtillon, Colombes, Issy-les-Moulineaux and Boulogne-Billancourt.
| Criterion | Detail |
|---|---|
| Founded | 1972 |
| Specialisation | National and international |
| Homes delivered | 60,000 and above |
| Position in the 92 | 1st in operations launched in 2025 |
| Towns | Clamart, Châtillon, Colombes, Issy-les-Moulineaux, Boulogne-Billancourt |
| Positioning | Family residential and first-time buyers |
Strengths
- The highest launch rate in the department, meaning a steady flow of new opportunities for buyers who can wait for the right programme.
- Presence in the two most expensive towns in the 92, Boulogne-Billancourt and Issy-les-Moulineaux, where new-build supply is scarce.
- A clear positioning on family residential and first-time ownership.
Weaknesses
- National steering: less finely tuned to local constraints than a developer based in the department.
- Entry prices not publicly consolidated at department level, which makes upfront comparison harder.
Ideal if: you are not in a hurry and want to maximise the number of programmes to compare along the Clamart, Issy and Boulogne axis.
3. Cogedim: betting on towns under redevelopment
Cogedim at a glance
A subsidiary of the Altarea group, Cogedim markets 6 programmes in Hauts-de-Seine, spread across as many towns: Bourg-la-Reine, Châtenay-Malabry, Gennevilliers, Issy-les-Moulineaux, Nanterre and Villeneuve-la-Garenne. It is the only player in the panel whose geography leans clearly towards the redevelopment towns in the north and south of the department, where prices per square metre remain the most contained.
| Criterion | Detail |
|---|---|
| Group | Altarea |
| Active programmes 92 | 6 |
| Towns | Bourg-la-Reine, Châtenay-Malabry, Gennevilliers, Issy-les-Moulineaux, Nanterre, Villeneuve-la-Garenne |
| Nanterre range | 4,920 to 6,020 €/m² |
| Villeneuve-la-Garenne range | 3,970 to 4,850 €/m² |
| Châtenay-Malabry range | 5,370 to 6,570 €/m² |
Strengths
- The lowest price ranges in the panel, with a floor around 3,970 €/m² in Villeneuve-la-Garenne.
- Coverage of 6 towns, on a par with Interconstruction, across a very different geographic footprint.
- Transparent price ranges per square metre, town by town.
Weaknesses
- Positioning concentrated on towns whose desirability depends heavily on how far urban redevelopment projects have progressed.
- A brand perceived as upmarket, which can sit awkwardly with the locations chosen in the 92.
Ideal if: your priority is the price per square metre and you accept betting on a town in transition rather than an already established location. This profile often overlaps with rental investment schemes in new-build, where growth potential matters as much as immediate yield.
4. Bouygues Immobilier: the brand strength of a national major
Bouygues Immobilier at a glance
A subsidiary of the Bouygues group founded in 1956, Bouygues Immobilier is one of France’s largest developers. In Hauts-de-Seine, the brand markets at least 5 programmes, with an average price positioning around 5,000 €/m². Its brand awareness and the strength of its parent group remain its main arguments, at the cost of a highly standardised offer from one department to the next.
| Criterion | Detail |
|---|---|
| Founded | 1956 |
| Group | Bouygues |
| Specialisation | National |
| Active programmes 92 | 5 and above |
| Indicative price | ~5,000 €/m² |
| Key strength | Brand awareness and output capacity |
Strengths
- A benchmark brand with guarantees backed by a major construction group.
- Steady output, with continuous renewal of programmes in the department.
Weaknesses
- Standardised products, with little adaptation to the specifics of each town in the 92.
- Pricing rarely among the most affordable in the department.
- Limited promotion of aided ownership schemes in Hauts-de-Seine.
Ideal if: the brand’s reputation and the financial strength of the group matter more to you than the price per square metre.
5. VINCI Immobilier: a focused offer in the west of the department
VINCI Immobilier at a glance
VINCI Immobilier has the most concentrated offer in the ranking within Hauts-de-Seine: 4 programmes totalling 99 available homes, located in Colombes, Meudon, Suresnes and Puteaux. This selectivity reads as a deliberate positioning on the west and north-west of the department, with entry prices ranging from 228,500 € to 457,000 € depending on the town.
| Criterion | Detail |
|---|---|
| Group | VINCI |
| Active programmes 92 | 4, totalling 99 homes |
| Towns | Colombes, Meudon, Suresnes, Puteaux |
| Entry price Colombes | from 228,500 € (Plurielles) |
| Entry price Meudon | from 379,000 € (Vue en scène) |
| Entry price Suresnes | from 457,000 € (Métamorphose) |
Strengths
- The second lowest entry price in the ranking in absolute terms, at 228,500 € on the Plurielles programme in Colombes.
- Regular commercial offers, with discounts of 3,000 to 5,000 € per home and notary fees covered on some programmes.
- A clear positioning on western towns well connected to La Défense.
Weaknesses
- The narrowest choice in the panel, with only 4 programmes and 99 available homes.
- No presence in the south of the department, therefore away from the towns served by Line 15 South.
Ideal if: you are specifically targeting Colombes, Meudon, Suresnes or Puteaux and are receptive to occasional commercial offers.
Which developer should you choose for your profile?
The right developer depends less on its size than on the town you are targeting and the budget available. Before deciding, it is worth measuring your borrowing capacity precisely, because the price gap between the north and the south of the department is more than twofold per square metre.
| Your profile | Our recommendation | Why |
|---|---|---|
| First-time buyer on a tight budget | Interconstruction | Entry at 185,000 € under 5.5% VAT in Bagneux |
| Priority on price per square metre | Cogedim | Floor at ~3,970 €/m² in Villeneuve-la-Garenne |
| Buying ahead of Line 15 South | Interconstruction | Present in Bagneux and Châtillon, two station towns |
| Looking for the widest choice | Les Nouveaux Constructeurs | Most operations launched in the 92 in 2025 |
| Sensitive to brand reputation | Bouygues Immobilier | National major, steady output |
| Targeting the west and La Défense | VINCI Immobilier | Colombes, Meudon, Suresnes, Puteaux |
Where to buy new-build in Hauts-de-Seine?
The department is one of the most contrasted in Île-de-France. Prices recorded in June 2026 range from around 4,740 €/m² in Bagneux and 4,980 €/m² in Nanterre up to 7,400 €/m² in Issy-les-Moulineaux and 8,140 €/m² in Boulogne-Billancourt. Clamart sits in between, around 5,610 €/m².
This hierarchy of towns is shifting, and that is the main new development of 2026. Line 15 South of the Grand Paris Express will serve five stations in Hauts-de-Seine: Pont de Sèvres, Issy, Clamart, Châtillon-Montrouge and Bagneux-Lucie Aubrac.
“Its opening is scheduled for 2027. It will link Pont de Sèvres to Noisy-Champs in 37 minutes, compared with over an hour today.” Société des grands projets, grandparisexpress.fr, 2026
The effect on prices is documented: properties within 500 metres of a new station generally gain 10 to 20% over the five years following the opening. Applied to the 92, this mechanism concerns Bagneux and Châtillon first, two towns whose entry prices remain among the lowest in the department even though they will be less than 40 minutes from Noisy-Champs.
For a first purchase, these two towns currently offer the best trade-off between entry price and growth prospects. Before deciding, weigh the benefits of buying new-build against older property, then check your eligibility for the loans and grants to finance a new home. The conditions for the 5.5% reduced VAT rate in urban regeneration zones are set out by the French public services on service-public.fr.
Frequently asked questions
Who are the best property developers in Hauts-de-Seine in 2026?
The main developers active in Hauts-de-Seine in 2026 are Interconstruction, Les Nouveaux Constructeurs, Cogedim, Bouygues Immobilier and VINCI Immobilier. Interconstruction has the widest coverage in the department, with 9 residences across 6 towns, and is the only developer in this ranking whose head office is located in Hauts-de-Seine, in Boulogne-Billancourt. Les Nouveaux Constructeurs launched the most operations in the department in 2025. Cogedim covers 6 towns, VINCI Immobilier 4 programmes totalling 99 homes.
Which developer offers the lowest entry prices in the 92?
The lowest entry prices recorded in July 2026 are around 185,000 € in Bagneux, on an Interconstruction programme eligible for the reduced 5.5% VAT rate. Next come entry points around 228,500 € in Colombes with VINCI Immobilier and 280,000 € in Puteaux. Across the department, the most affordable towns per square metre are Villeneuve-la-Garenne, Bagneux and Nanterre.
How do you choose a property developer in Hauts-de-Seine?
Check the developer’s actual presence in the target town, the number of homes already delivered there, the guarantees (completion guarantee, ten-year and two-year warranties), the environmental certifications of the programme (RE2020, NF Habitat HQE) and the aided schemes on offer. In a department as contrasted as the 92, where the price per square metre varies twofold from one town to the next, detailed local knowledge matters more than the size of the developer.
Does the Grand Paris Express change the picture for buying in the 92?
Yes. Line 15 South will serve five stations in Hauts-de-Seine: Pont de Sèvres, Issy, Clamart, Châtillon-Montrouge and Bagneux-Lucie Aubrac. The Société des grands projets has announced its opening for 2027. Properties within 500 metres of a new station typically gain 10 to 20% in value in the five years following the opening, which shifts interest towards historically more affordable towns such as Bagneux and Châtillon.
Which towns in Hauts-de-Seine are best for buying new-build?
Bagneux, Châtillon and Clamart combine still-contained entry prices with the arrival of a Line 15 South station. Nanterre and Villeneuve-la-Garenne remain among the most affordable towns in the department. Conversely, Boulogne-Billancourt and Issy-les-Moulineaux exceed 8,100 and 7,400 €/m² respectively, a level that reserves these towns for comfortable budgets.
