LMB MARTIN FRERES

What LMB MARTIN FRERES does

LMB Martin Frères is a privately held French family-owned wood construction and joinery company founded in 1862 and headquartered in Montilliers, Maine-et-Loire. Now in its sixth generation of family operation under co-owners Jean-Michel and Jean-Sébastien Martin, both designated Maître Artisan, the company runs two interlocking divisions: traditional wood joinery (windows, doors, shutters, gates, stairs, parquet, paneling, interior fit-out) and eco-construction (timber-frame houses, roofing/charpente, insulation, cladding, verandas, terraces). All output is custom made-to-measure, with production executed across 1,310 m² of dedicated workshops (joinery, carpentry, cutting) plus a 600 m² storage building, using a 2–3 team module-based assembly system that allows continuous workshop and on-site work in parallel.

Underlying capability is built on an in-house design office for project feasibility, FSC/PEFC-certified timber sourcing, traditional tenon-and-mortise joinery, and modern last-generation equipment. Heritage restoration covers 15th–19th century period work including hardware recovery. The company holds Eco Artisan (CAPEB), BBC EFFINERGIE, RGE, Bâtir avec l'environnement, Maître Artisan, FSC, and PEFC certifications, with technical performance on its first BBC-labeled house at 0.22 m³/h·m² air infiltration (versus 0.60 norm) and 37.9 kWh-ep/m² CEP (versus 50 norm). It maintains a structured apprenticeship pipeline of ~8 apprentices per year split between carpentry and joinery trades.

The business model is project-based B2C and B2B custom construction sold directly to clients in the Grand Ouest region of France, with pricing determined per project under fixed-price and decennial guarantees, no publicly disclosed standard price list, and payment tied to work progress. Customer segments include individual homeowners (primary), territorial collectivities and professionals, heritage-monument owners, and the agricultural sector. GTM is sales-led direct engagement via phone and email, supported by an extensive website portfolio and a Facebook page. Revenue is not publicly disclosed; headcount is 30–33 collaborators per primary sources.
