HVA CONCEPT

What HVA CONCEPT does

HVA CONCEPT, founded in 2008/2009 and headquartered in Fresnay-sur-Sarthe, France, designs, manufactures, and delivers off-site prefabricated bathroom and structural modules for the French construction market. It operates as a wholly-owned subsidiary of Eiffage Construction Industries, embedded within Eiffage Group's 'Solutions Industrialisées (Hors-Site)' pole alongside sister brands SAVARE (wood) and GOYER (facade/steel). The company's product portfolio comprises five trademarked lines: Hva'ini® (high-resistance concrete-floor module), Wa'ood® (eco-designed 40% lighter wood-based module), Hva'kase® (large-format structural room module), Hva+® (Plug & Play with integrated kitchen and thermodynamic hot water), and Wicube® (3D structural modules). All modules are 100% prefabricated at the single Fresnay-sur-Sarthe factory, which produces approximately 4,000 modules per year (18/day) and has shipped over 40,000 units cumulatively across a library of 750+ engineered models, with a stated 50+ year product lifespan and near-zero defect delivery rate.

The business model is project-based B2B with custom quoting per module based on specifications, equipment, finishes, and dimensions, yielding 7-8 week time savings versus traditional construction. HVA Concept generates revenue from three streams: hardware sales of modules, integrated engineering/technical studies delivered by its 100% BIM design office, and on-site support/training during delivery. Its 100+ employees serve four primary verticals — Healthcare (hospitals, EHPADs, clinics), Residential (student housing, social/collective housing), Hospitality (hotels and resorts), and Government/Defense Housing (notably the CEGeLog program with the French Ministry of Armed Forces). Distribution is exclusively through direct enterprise field sales and an integrated design office, supplemented by trade-show presence (BATIMAT, SantExpo, Union Sociale pour l'Habitat congress), a company blog, and the Eiffage Hors-Site WibridNews newsletter. Named customers include Greystar (365 modules), Apsys/CANOPIA (393 units), Lilo (613 units), Constellation (481 units), Marriott/Moxy, Pullman, Eiffage, and the French Ministry of Armed Forces.
