What Boisseau Bâtiment does

Boisseau Bâtiment (SAS Boisseau Bâtiment) is a French general construction company (entreprise générale du bâtiment) headquartered in Botz-en-Mauges, Maine-et-Loire, operating exclusively within the Pays-de-la-Loire region — specifically the basins of Nantes, Angers, Cholet, Segré, the Mauges, and North Vendée. Founded in 1839, the family-controlled firm (part of Groupe Boisseau, led by President Charles Boisseau and co-director Damien Gallard) employs approximately 140 collaborators and completes around 200 construction projects per year. Its core offerings span traditional masonry and structural work (gros œuvre), wood-frame construction, facade renovation and external thermal insulation (ITE), energy retrofitting, residential extensions and restructuring, and full design-build (conception-réalisation) services delivered in partnership with architects and engineering consultancies.

The company's technical differentiator is an in-house prefabrication capability: at its Botz-en-Mauges site, Boisseau runs dedicated workshops producing prefabricated wood and concrete elements (walls, panels, frames, floors) that are then installed on construction sites, reducing timelines and improving quality control. It applies this multi-material expertise (béton, bois, acier) across both B2B and B2C clients, with named enterprise projects including a 15,000 m² PACK'R industrial site and a 4,475 m² healthcare laundry for CESAME, alongside public-sector work for local authorities and social landlords, and a high-volume tail of individual homeowner renovation and energy-retrofit jobs.

Boisseau generates revenue through project-based, quote-priced contracts (no public pricing) typically structured as multi-year engagements for professional clients. Its go-to-market is enterprise field sales via direct relationships and public tenders on the professional side, combined with direct inbound from private individuals on the residential side. The company runs an internal training program (Campus Boisseau), has formal youth-talent partnerships with EPIDE and Mauges Communauté, and in 2025/2026 began investing in content marketing through a YouTube channel and LinkedIn presence. Charles Boisseau was elected President of the Fédération Française du Bâtiment de Maine-et-Loire in December 2025, reinforcing the firm's regional institutional positioning.
