Maisons Stéphane Berger

What Maisons Stéphane Berger does

Maisons Stéphane Berger, legally operated through MSB SUD ALSACE (RCS Mulhouse, SIREN 494 392 632), is a French custom home builder founded in 1999 and headquartered at 15 rue de Didenheim, 68200 Mulhouse Dornach. The company designs and constructs individualized single-family homes for buyers in the Alsace region and the Territoire de Belfort, operating through six physical agency locations (Mulhouse, Strasbourg, Colmar, Sélestat, Haguenau, Belfort) and a Coach Projet-led direct sales process that covers land search, architectural design, and construction supervision.

The technical core is the standard French residential build stack — CCMI (Contrat de Construction de Maison Individuelle) contract framework, RE 2020 environmental compliance, and NF Habitat Haute Qualité Environnementale certification — augmented with proprietary branding including the Maison Évolutive / Mon Évolutive modular-extensibility concept, a 400+ point quality-control regime, an exclusive #EnTouteQuiétude post-sale guarantee package, and a digital Suivi de Chantier (construction tracking) portal. Construction is executed through a network of vetted local artisan and industrial partners under a Conducteur de Travaux, with land supplied partly through in-group partner Terre et Développement.

The business model is project-based, one-time transactional revenue on house + land packages ranging from approximately €243,000 for entry-level 70-92 m² units to €740,000 for premium 157 m² units, with two delivery options (Prêt à Décorer and Clés en Mains) that adjust scope and price. Maisons Stéphane Berger is a brand within the Groupe Vivialys multi-brand housing group, alongside sister brands Maisons Oxygène, Trianon Résidentiel, and Carré Habitat. Customer mix is dominated by individual home buyers and families, with supplementary segments for cross-border (Swiss frontalier) commuters and small property investors, all served exclusively via direct sales rather than through third-party channels.
