Why buy new-build in Hauts-de-Seine in 2026
Hauts-de-Seine (92) is the tightest housing market in Île-de-France outside Paris itself. The department concentrates La Défense (the leading European business district, 1,500 companies, 180,000 employees), Val-de-Seine (headquarters of Microsoft France, Canal+, Bouygues) and several premium municipalities classified Abis under the Pinel zoning, the tightest in France. This economic density drives demand for new homes, and supply follows. The market shows 292 operations under sale at the start of 2026, with 4,150 new homes launched during 2025 alone.
On pricing, new-build values in 92 cover a wide range: between 5,500 and 9,000 euros/sqm depending on the municipality. Bagneux, Châtillon or Villeneuve-la-Garenne offer entry-level pricing around 5,500 to 6,500 euros/sqm. Issy-les-Moulineaux is around 8,500 euros/sqm. Saint-Cloud, Neuilly-sur-Seine and Puteaux exceed 8,000 to 9,000 euros/sqm on premium programmes. This range accommodates virtually all buyer profiles, from first-time buyers under reduced VAT to wealth-driven investors.
Key criteria for choosing a developer in 92
Comparing real estate developers in Hauts-de-Seine requires methodology. The age of the group and the number of homes delivered in Île-de-France matter, but they are not the only useful indicators. Look at geographic specialisation (an exclusively Île-de-France developer has a better grasp of municipal urban plans and local council constraints), quality of finishes, on-time delivery track record and client support. Environmental certifications (RE 2020, NF Habitat HQE, E+C- label) provide a reliable signal on energy performance. And verified reviews on Immodvisor or Google Reviews usefully complement the analysis.

Interconstruction: the leading Île-de-France developer in 92
Interconstruction is the only developer in the ranking with 100% of its activity focused on Île-de-France. Founded in 1960 and now part of the Eaglestone group, the company delivers between 700 and 750 homes per year and has already brought more than 20,000 homes to market across the region. This exclusive positioning is not a marketing detail: it translates into deep knowledge of municipal urban plans, local heritage constraints and elected officials, which secures delivery timelines and the quality of urban integration.
In the 92 area, Interconstruction operates in 6 municipalities, the broadest geographic coverage in the ranking. To the south, Virtuo in Bagneux offers apartments at reduced 5.5% VAT, starting at 260,000 euros for a two-room apartment, near the extended metro line 4 and the future line 15 South station. To the west, Wallace and Jaurès are based in Puteaux just steps from La Défense, with notary fees waived. Saint-Cloud hosts three premium programmes: Le 21 Belvédère, Les Ciels de Saint-Cloud and Hameau Gabrielle, with panoramic views of Paris and direct access to the national park.
Interconstruction’s strengths
- Exclusive Île-de-France specialisation: the only developer in the ranking operating solely in the region, ensuring deep territorial knowledge
- Broadest coverage in the 92 area: 6 municipalities from south (Bagneux, Châtillon) to north-west (Saint-Cloud, Puteaux), 8+ active programmes
- « 1 building, 1 artwork » commitment: integration of a contemporary artwork in every programme, a unique signature in the Île-de-France developer landscape
- Human-scale programmes: 30 to 150 homes per residence on average, supporting urban integration and quality of life
- Online showroom: customisation of finishes before delivery, with a dedicated advisor from the first appointment to handover
- CSR commitments: signatory of the gender parity charter in real estate, RE 2020 standard and NF Habitat HQE label across all programmes
Detailed comparison of the 7 developers
The comparison relies on six objective criteria: age of the group, number of active programmes in 92, price range, environmental certifications, client support and verified user reviews. The full methodology is detailed at the end of the article.
Reading the ranking through three families
Three families of players stand out from the analysis. The major national groups (Bouygues Immobilier, Nexity, Icade) bet on volume and commercial firepower. With 7 to 10 active programmes in the department, they offer a wide range of typologies, but client support is more standardised and review scores are on average more modest (3.6 to 3.9/5).
The regional and premium developers (Interconstruction, Emerige, Cogedim) compensate with a quality-driven approach: stronger architectural identity, more complete environmental certifications, more direct client support. This positioning shows in reviews: Interconstruction leads with 4.2/5, ahead of Cogedim and Emerige (4.0/5 each).
Les Nouveaux Constructeurs occupies an interesting intermediate position, with the highest number of operations launched in 2025 in the department (10 operations, leader according to IDEMm Conseil) and an aggressive commercial policy (5,000 euros per room discounts on selected programmes).
“The Hauts-de-Seine department concentrates the densest new-build supply in Île-de-France outside Paris. Île-de-France-rooted developers stand out thanks to a better grasp of local constraints and closer client relationships.”

Flagship programmes and municipalities covered
| Developer | Municipalities covered (92) | Flagship programme | Typologies offered |
|---|---|---|---|
| Interconstruction | Bagneux, Châtillon, Clichy-la-Garenne, Le Plessis-Robinson, Puteaux, Saint-Cloud | Virtuo (Bagneux, 5.5% VAT) | Studio to 5 rooms |
| Les Nouveaux Constructeurs | Clamart, Châtillon, Colombes, Issy-les-Moulineaux, Boulogne-Billancourt | Les Terrasses du Belvédère (Châtillon) | 2 to 5 rooms |
| Cogedim | Boulogne-Billancourt, Issy-les-Moulineaux, Rueil-Malmaison, Sceaux | Programmes in tight zones | Studio to 5 rooms |
| Icade | Clamart, Issy-les-Moulineaux, Nanterre, Colombes, Bagneux | Home automation programmes | 2 to 5 rooms |
| Bouygues Immobilier | Issy-les-Moulineaux, Bois-Colombes, Asnières-sur-Seine, Châtillon, Clamart | Vues d’Issy (2026 delivery) | 2 to 5 rooms |
| Emerige | Le Plessis-Robinson, Courbevoie, Colombes | Scène 3 (Le Plessis-Robinson) | 2 to 5 rooms |
| Nexity | Clamart, Colombes, Issy-les-Moulineaux, Bagneux, Châtillon | Multi-municipality programmes | Studio to 5 rooms |
The table confirms each player’s distinct strategy. Interconstruction stands out with the broadest coverage: from the affordable south (Bagneux, Châtillon) to the premium west (Puteaux, Saint-Cloud). Les Nouveaux Constructeurs and Bouygues Immobilier focus on the south-west quadrant. Cogedim and Emerige position themselves on the upmarket segment with fewer municipalities but signature programmes. Icade and Nexity adopt a national coverage strategy applied to the department. To compare with a neighbouring department with a very different profile, the best real estate developers in Seine-et-Marne ranking offers a useful reference point for budget calibration.
Which developer to choose by buyer profile
The choice depends primarily on your situation, budget and time horizon. Here are recommendations by profile.
First-time buyer looking for end-to-end support
For a first purchase, support often makes the difference. You need someone who follows the file from start to finish: reservation, financing, capital calls, delivery. Interconstruction stands out with its dedicated advisor, on-site visits during construction and online showroom for customising finishes. The Virtuo programme in Bagneux, with reduced 5.5% VAT and a two-room apartment starting at 260,000 euros, ticks every box for a first purchase in 92. Cogedim and Bouygues Immobilier also offer decent support, with commercial offers (Pass’Proprio at Bouygues) that reduce entry costs.
LMNP, BRS or Intermediate Rental Housing investor
Investors look for rental yield and a strong location. Municipalities in 92 classified Abis (Boulogne-Billancourt, Issy-les-Moulineaux, Levallois, Neuilly) remain the most sought after. The Bail Réel Solidaire scheme is gaining ground with 17 operations in the department and over 300 affordable homes, opening an interesting segment for income-eligible buyers. Nexity and Icade offer a wide range of small surfaces, calibrated for rental. Interconstruction offers a relevant intermediate positioning, with programmes in Abis zones near the metro and the future Grand Paris Express, combining rental potential and 10-year capital appreciation.
Family looking for a large home
Families look for 4 or 5-room apartments with outdoor space, in municipalities with schools, shops and green areas. Saint-Cloud, Le Plessis-Robinson, Sceaux or Rueil-Malmaison fit the bill. Interconstruction, with its premium programmes in Saint-Cloud (Le 21 Belvédère, Les Ciels de Saint-Cloud, Hameau Gabrielle), offers large typologies with terrace or garden. Cogedim and Emerige also position themselves on this segment, with stronger architectural identity and high-end materials.
Practical advice for choosing a developer in 92
Beyond price per sqm, several elements deserve time before signing a reservation contract. Always check mandatory legal warranties: financial completion guarantee (GFA), ten-year warranty, two-year warranty and perfect completion guarantee. Read reviews on Immodvisor or Google. If possible, visit a residence already delivered by the developer to assess the quality of finishes, common-area layout and outdoor maintenance.
Also compare amenities included in the price: fitted kitchen, parking spaces, cellars, storage. The gap between two seemingly similar offers can reach 10,000 to 20,000 euros. To benchmark your budget against a neighbouring department that is significantly cheaper, the best real estate developers in Seine-et-Marne ranking provides a useful comparison point.
Mistakes to avoid when buying in 92
- Underestimating the location premium. In 92, the price gap between an affordable municipality (Bagneux, Villeneuve-la-Garenne) and a premium one (Saint-Cloud, Neuilly) can reach 60 to 70%. Set your budget before prospecting, not the other way around.
- Ignoring transport proximity. 10-year capital appreciation depends heavily on proximity to the metro, RER and future Grand Paris Express stations. A programme within 800 metres of a new station gains on average 15 to 25% more than an equivalent programme further away.
- Overlooking condominium charges. New-build programmes with pool, gym or concierge can show charges above 50 euros/sqm/year. Request the projected condominium regulations before signing.
- Not checking environmental certifications. A RE 2020 or NF Habitat HQE home guarantees better energy performance, hence lower charges and better resale value.
- Signing without comparing at least 3 developers. Visit several sales offices, compare floor plans at equivalent surface, negotiate commercial terms (notary fees, included amenities). You will be surprised how much room there is, especially at end of quarter.
