SERRU HABITAT BOIS

What SERRU HABITAT BOIS does

SERRU HABITAT BOIS is a privately held French SARL founded in 2000 and headquartered in Locqueltas (near Vannes), Morbihan, specializing in the design and construction of custom timber-frame (ossature bois) houses, wood-frame extensions, vertical elevations, and exterior wood features such as terraces and pergolas. Its core technology is conventional wood-frame construction using sustainable materials including wood frame structures, wood fiber insulation, cellulose wadding, and wood wool insulation; the company operates an in-house study office (Bureau d'études) for design, 3D planning, permit filing, and project coordination, alongside a joinery workshop that prefabricates wall frames under controlled conditions before crane delivery to site. A closely integrated partnership with Menuiserie Etablissements Serru supplies frames, roofing, joinery, insulation, cladding, and decking, while the company draws on local artisans for masonry, electrical, plumbing, and finishing trades.

The company sells exclusively on a direct, project-based, quote-driven basis to individual homeowners in the Morbihan department, offering a single-interlocutor service model that spans initial concept through final delivery. Revenue is generated through professional-services contracts for full custom home builds, extensions, partial projects (including Hors d'Eau/Hors d'Air weather-tight enclosures), and exterior wood installations; pricing is not publicly disclosed. With 1–10 employees and no external funding, the firm operates as a founder-family construction business with a narrow geographic footprint, RE 2020 regulatory compliance positioning, and an ecological brand narrative centered on healthy, renewable materials.

Direct peers

• Natilia: France's largest specialist timber-frame (maison ossature bois) homebuilder, operating a national franchise network. Directly comparable as a French MOB-only homebuilder delivering turnkey custom homes to individual homeowners, though at substantially larger scale than Serru.
• Trecobat: French custom homebuilder active in western France including Brittany, offering timber-frame construction alongside traditional methods. Directly comparable as a regional custom homebuilder serving similar homeowner segments with overlapping geographic reach.
• Habitat Concept: Regional French custom homebuilder offering turnkey project management with timber-frame capability. Comparable as a project-managed custom homebuilder serving individual homeowners with single-interlocutor delivery, though broader in geographic coverage.
• Edena: French ecological/healthy homebuilder focused on bio-based materials and energy performance, including timber-frame construction. Highly comparable on the ecological positioning, healthy insulation (wood fibre, cellulose), and RE 2020-aligned value proposition.

Broad incumbents

• AST Groupe: Multi-brand French homebuilder group with timber-frame offerings (including the Demeures Côte d'Argent brand). Comparable as a regional custom homebuilder with MOB expertise, but operates across multiple brands and regions with much larger headcount.
• Maisons Pierre: Large national French homebuilder offering a broad range of house types including timber-frame models. Comparable on end-customer segment (individual first-time and family buyers) and project-based custom build, but at much larger scale and with conventional construction as the core offering.
• Hexaôm (formerly Maisons France Confort): One of the largest French homebuilders, offering both traditional and timber-frame houses. Comparable as a competing custom homebuilder in France, but at national scale and with a much broader portfolio that includes conventional masonry builds.

Emerging players

• Les Constructions du Bois: Small/mid French timber-frame construction specialist serving individual homeowners with custom MOB projects. Comparable on niche MOB focus and homeowner customer base, though smaller and less established than national brand peers.
