What Legendre does
Groupe Legendre is a privately held, family-owned European construction, real estate, energy, and hospitality services group founded in 1946 and headquartered in Saint-Jacques-de-la-Lande near Rennes, France. The group operates through four core business lines: Legendre Construction (building, civil engineering, refurbishment, and steel structure construction via subsidiary OMS), Legendre Immobilier (property development, asset management, urban redevelopment under sub-brands SoLive and Whoo/Whoorks), Legendre Energie (solar installation, energy efficiency via Armorgreen and Ener24 subsidiaries and the Effinside JV with Delta Dore), and Legendre Exploitation (hotel and arena operations). The company also holds interests in innovation ventures including Wave-Op, a joint venture with Geps Techno developing the Dikwe wave-powered breakwater technology.
The business serves enterprise and institutional clients across banking (Crédit Agricole Brie Picardie, Raiffeisen Group), telecommunications (Orange), automotive (PSA/Stellantis), real estate investment (MEAG, Ardian), aerospace (Aéroport Toulouse-Blagnac), and public infrastructure through project-based contracts won via competitive tender and direct negotiation. Underlying technology includes BIM-based project planning, ACT low-carbon cement (delivering up to 55% carbon reduction on Parker & Baker), self-consumption solar installations (15 MW cumulative by 2018), and the Dikwe oscillating-panel breakwater — France's first full-scale wave-powered breakwater demonstrator. The group operates 24 agencies across France, the UK, Jersey, Portugal, Switzerland, and historically West Africa, employing approximately 2,500 staff and generating roughly €1 billion in 2024 turnover.
Legendre generates revenue through four primary streams: construction services (project-based contracts), real estate development (property sales and development fees), energy services (installation contracts and ongoing multi-technical service contracts via Ener24), and facilities management/hospitality (managed services through Legendre Exploitation). Pricing is project-specific, determined through competitive tendering and direct negotiation with public and private clients under multi-year contracts. Customer acquisition is direct enterprise field sales, supplemented by industry-event presence (e.g., Seanergy for wave energy), PR-driven earned media, and LinkedIn-led top-of-funnel activity. The company is currently led by third-generation President Vincent Legendre, with a recently appointed Deputy CEO (Thomas Vandecasteele, November 2025) charged with accelerating international development.
