Castel Menuiserie Agencement

What Castel Menuiserie Agencement does

Castel Menuiserie Agencement is a French artisanal joinery and interior fitting firm, founded in 1999 in Châteaugiron, Brittany, structured as a SARL (Société à Responsabilité Limitée) with €7,625 registered capital. The company operates an integrated "A-to-Z" project model covering in-house interior design (with interior architects, project managers, and draftspersons comprising roughly 25% of the workforce), custom CNC fabrication in a 1000m² workshop equipped with 5-axis and 3-axis machines, administrative handling for heritage-zone projects and building permits, and on-site installation, all coordinated through a single point of contact. Its customer portfolio spans 16 product verticals organised into two parallel segments: 8 professional (B2B) sectors — Bureau (offices), Magasin (retail), Optique (opticians), Hôtel et Restaurant, Menuiserie, Clinique (medical clinics), Tabac Presse, and Beauté (beauty/wellness); and 8 residential (B2C) sectors — Cuisine (kitchen), Séjour (living room), Chambre (bedroom), Dressing (wardrobe), Salle de bain (bathroom), Placard (closet/storage), Menuiserie, and Entrée (entryway).

Revenue is generated on a project-by-project quote basis with no public price list; pricing is scoped per project based on materials, complexity, and specifications. The company maintains a named project portfolio including Clinique de la Baie, Le Roscanvec, MBA Mutuelle, Vandemoortele, CEGELEC, KEOLIS, Suite Parentale (Saint-Malo), Institut Mare Maris, and multiple optician and beauty-salon fit-outs. Distribution is direct field-sales within the Brittany region, with an ecosystem of architect and interior-designer partners (Boissière&Gaulay and JoyDesign as Core partners) generating project referrals.

The business is led by current gérant Maxime Guillery (a former in-house apprentice), with Laurent serving as architecte d'intérieur et chargé d'affaires with 22 years' tenure and a work-mérit medal. The firm operates with approximately 20 employees (per the company website; firmographics records 11), serves a single sub-national geography (Bretagne), has no subsidiaries or parent entity, no external funding, no disclosed technology platform, and no AI/ML capability visible in source materials.
