Groupe Rose

What Groupe Rose does

Groupe Rose is a privately-held French wood construction group founded in 1949 by Lucien ROSE in St-Gouëno, Côtes-d'Armor, and now headquartered in Lamballe, Brittany. Operating as a SAS with approximately 250 employees and group turnover of €70 million, the group is structured around four wholly-owned subsidiaries: Rose Charpente (the core construction business and France's first constructor of pig farming buildings, with €15.7M subsidiary turnover and 74 staff), Protac (northern timber transformation near Saint-Brieuc), Puidukoda (wood processing in Estonia), and Norsilk (exterior wood cladding). The group claims a presence in more than 35 countries.

The group's technical platform centers on engineered timber-frame (fermette) construction specialized for livestock buildings, particularly pig farming. Differentiated, patented or award-winning components include the Diful'R diffuser ceiling system (patented, XPS with adaptable perforations), the Flud'R 360° variable air inlet module (3 Innov'SPACE stars in 2015, developed with Anavelec; passive operation with no electric or pneumatic actuators), the Regul'R synthetic-fibre air-flow regulation felt, and the Isol'R+ PIR foam insulation panel. Manufacturing is concentrated at a 39,000 m² site in Lamballe with two large assembly workshops capable of producing trusses at an average construction rate of 800 m²/day, with cumulative output reported at 3,500,000 m² and 3,000+ realizations.

The business model is sales-led B2B with custom quotation-based pricing on turnkey contracts that bundle design, manufacturing, and in-house installation. Delivery and installation are handled by the group's own teams with long-reach crane trucks covering all of French national territory, with a separate supply-only channel for self-installation customers. Product revenue streams include fermette construction, ventilation and insulation systems (Diful'R, Flud'R, Regul'R, Isol'R+), Sanit'R hygiene booths, doors (interior and exterior), PVC windows, aluminum gutters, and light wells. Primary customers are professional pig farmers (éleveurs porcins) and, more broadly, livestock farmers, with no evidence of recurring SaaS or service revenue; commercial engagement is via a B2B sales team conducting technical-commercial interviews.
