Why is Hauts-de-Seine the leading new-build department in Île-de-France
La Défense and Val-de-Seine, two economic engines of European scale
La Défense remains the leading business district in Europe with 1,500 companies and 180,000 employees on site. The Val-de-Seine area, stretching across Issy-les-Moulineaux and Boulogne-Billancourt, is the second economic hub of the department, hosting the headquarters of Microsoft France, Canal+ and Bouygues. The unemployment rate is among the lowest in Île-de-France and the area is classified Abis, the tightest housing zone in France under the Pinel zoning. The academic ecosystem strengthens this attractiveness with Paris-Nanterre University, HEC Jouy-en-Josas nearby and several leading business schools. This economic density explains the constant rental pressure and the steady appreciation of new-build properties, especially in municipalities adjacent to the tertiary hubs.
A world-class transport network, amplified by the Grand Paris Express
The 92 area is served by 7 metro lines, 3 RER lines (A, B, C) and 3 tramway lines (T2, T6, T10). The Grand Paris Express line 15 South, currently being finalised for a 2026 launch, will add new stations in Issy, Clamart and Bagneux. According to Société des Grands Projets, the line will connect 22 municipalities and carry up to one million passengers per day. The metro line 4 extension to Bagneux is already operational, and the T1 tramway extension to Colombes is scheduled. The proximity of Orly and Roissy airports through the extended line 14 and RER B makes Hauts-de-Seine the best-served department in Île-de-France after Paris itself.

A new-build market in full recovery, 292 operations and 4,150 homes launched in 2025
According to IDEMm Conseil, 292 operations were under sale on January 1, 2026 across 34 of the 36 municipalities in the department. In 2025, 105 new operations broke ground, representing 4,150 new homes put on the market, while the second-hand market kept declining (7,200 transactions versus 12,357 the year before). Three municipalities concentrate most of the supply: Clamart (21 operations), Colombes (20) and Issy-les-Moulineaux (17). The Bail Réel Solidaire (BRS) scheme is also gaining ground with 17 operations and over 300 affordable homes. On pricing, new-build values range between 5,500 and 9,000 euros per sqm depending on the municipality: Bagneux and Châtillon offer entry-level pricing around 5,500 to 6,500 euros, while Saint-Cloud and Neuilly exceed 8,000 to 9,000 euros.
Interconstruction
Over 60 years of expertise and 8+ active programs in Hauts-de-Seine
Founded in 1960 and now part of the Eaglestone group, Interconstruction delivers between 700 and 750 homes per year. The 92 area is its flagship department with a presence across 6 municipalities: Bagneux (Virtuo, reduced 5.5% VAT, starting at 260,000 euros), Châtillon (Le 57 République), Clichy-la-Garenne (L’Incontournable), Le Plessis-Robinson (Nouvelle Vague), Puteaux (Wallace, Jaurès) and Saint-Cloud (Le 21 Belvédère, Les Ciels de Saint-Cloud, Hameau Gabrielle). It is the only developer in the ranking with 100% of its activity focused on Île-de-France, which translates into deep knowledge of municipal urban plans (PLU) and local heritage constraints.
Premium addresses from Bagneux to Saint-Cloud
Coverage spans the department from north to south. Saint-Cloud hosts upscale programs with panoramic views of Paris and direct access to the national park: Le 21 Belvédère and Les Ciels de Saint-Cloud embody this positioning. Puteaux features Wallace and Jaurès, just steps from La Défense, with notary fees waived. In Le Plessis-Robinson, Nouvelle Vague stands at the heart of the Architects’ District. Bagneux focuses on accessibility with Virtuo at reduced 5.5% VAT, near the extended metro line 4 and the future line 15 South station. Châtillon (Le 57 République) and Clichy-la-Garenne (L’Incontournable) complete this network.
A distinctive commitment, art, quality of life and gender parity
The « 1 building, 1 artwork » charter integrates a contemporary artwork into every delivered program, a unique signature in the Île-de-France developer landscape. The group is also a signatory of the gender parity charter in real estate. Programs comply with the RE 2020 standard and the NF Habitat HQE label. An online showroom allows buyers to customise finishes before delivery. On the operational side, the joint development conducted in Courbevoie alongside Emerige and Brownfields (295 homes at Les Fauvelles) demonstrates the capacity to deliver large-scale mixed operations.
Les Nouveaux Constructeurs
According to the IDEMm Conseil ranking of January 2026, Les Nouveaux Constructeurs is the most active developer in Hauts-de-Seine in terms of operations launched during 2025. Active since 1969 and the author of more than 60,000 homes delivered nationwide, the group is positioned on the family residential and first-time buyer segment. Current programs are concentrated in Clamart, Châtillon (Les Terrasses du Belvédère, with a 5,000 euros per room commercial discount), Colombes, Issy-les-Moulineaux and Boulogne-Billancourt. Architecture favours contemporary volumes and human-scale residences. Buyers looking to compare home loan financing options before committing will find a dedicated guide covering the available levers.
Emerige
Founded in 2003, Emerige focuses on Paris and the inner suburbs. The developer has carved out a position on the architecturally distinctive segment, with particular attention paid to noble materials and worked façades. Several emblematic programs mark the 92 area: Scène 3 in Le Plessis-Robinson, designed by Ange-Jacques Gabriel and co-developed with Foncier Promoteur in the Architects’ District (with an urban micro-forest and a vegetated basin), the joint development of 295 homes in Courbevoie at Les Fauvelles with Interconstruction and Brownfields, and several operations in Colombes. The positioning targets clients demanding on architectural identity and the environmental quality of outdoor spaces.
Icade
A subsidiary of the Caisse des Dépôts et Consignations, Icade celebrates 70 years of existence in 2024 and counts more than 100,000 homes delivered in France. It is the second most active developer in the 92 area in 2025 according to IDEMm Conseil. Programs are deployed in the most dynamic municipalities of the department: Clamart (which ranks first with 21 operations across all developers), Colombes (20 operations), Issy-les-Moulineaux, Nanterre and Bagneux. Each program integrates a home automation solution and offers extensive customisation of finishes. The backing of a public institutional player is a strong argument for buyers seeking financial stability, particularly in a long-term rental real estate investment strategy.
Bouygues Immobilier
Bouygues Immobilier, a subsidiary of the Bouygues group founded in 1956, currently markets 5 or more programs in the 92 area. Issy-les-Moulineaux hosts Vues d’Issy with delivery scheduled for the second quarter of 2026. Bois-Colombes concentrates three residences (Hisséo, ExalT, Canopéa). Asnières-sur-Seine offers Olympéa, Châtillon Premières Loges, and Clamart Le Majorelle and Lutecia. The Pass’Proprio commercial offer combines waived notary fees, covered bank application fees and discounts of 2,000 to 5,000 euros per room. The financial strength of the Bouygues group and the vertical integration with the group’s BTP subsidiaries guarantee complete coverage of constructor warranties (decennial, biennial, perfect completion).
