What KS groupe does

KS Groupe is a privately held, family-owned multidisciplinary construction and real estate group headquartered in Bischheim, Alsace (France), founded in 1958 and operating today under a Société à Mission governance structure led by the Sauer family. The group is organized as a platform of 12 wholly-owned subsidiaries spanning the full building lifecycle — from structural work and general contracting (KS Construction), electrical and HVAC engineering (KS Énergies, Altherm), industrial process engineering (CICAL Synergies, BC2I), wood and bio-sourced construction (MOOG Bâtisseur Bois), interior fit-out and design (KS Aménagement, Creatio), real estate development and asset management (KS Promotion, AREFIM), facility management (KS Solutions), and viticultural engineering (INGEVIN).

The business model is project-based B2B contracting acquired through competitive tenders, RFPs, and direct enterprise client relationships. KS Groupe acts as general contractor or main builder on industrial, commercial, hospitality, healthcare, residential, and institutional projects across France, with primary concentration in the Grand-Est region and recent expansion into Hauts-de-France. The group generated €160M of revenue in FY2024 with a workforce of 460+ across its 12 subsidiaries. Pricing is quote-driven and non-public, reflecting standard general contracting practice. KS Groupe further differentiates through its Société à Mission status (since 2022), a shareholder endowment fund redistributing economic value to general-interest associations, B Corp certification for AREFIM, and consecutive Deloitte Best Managed Companies labels (2025, 2026).
