What Les Constructeurs du Bois does

Les Constructeurs du Bois (LCB) is a French real-estate developer and eco-constructor founded in 2011 and headquartered in Épinal, in the Vosges department. The company is publicly listed on Euronext (epa:MLLCB) since October 2020 and operates with a small team of 11-50 employees. LCB specializes in low-carbon timber-frame construction (ossature bois / MOB) using bio-sourced materials, sourcing wood exclusively from the Vosges Massif. Its core offerings span four product lines organized under sub-brands: Eco'City (eco-districts), Medicentre (medical/health centers), Paysages (managed senior residences), and Récréation (childcare and schools), all distributed via the LCB'Immo direct-sales platform. Active projects span ~15 towns across the Grand Est region (Épinal, Nancy, Villerupt, Gérardmer, Houdemont, Ensisheim, Faulx, Xonrupt-Longemer, Chantraine) and extend to Alpes-de-Haute-Provence (Digne-les-Bains).

LCB's revenue model combines one-time property sales (apartments from ~110K EUR, villas up to 575K EUR, commercial and medical cells from 2,800 EUR/m²) with a smaller recurring rental stream (residential and medical from ~980-1,200 EUR/month). Customers span four segments: private individual buyers (first-time, family, senior, cross-border near Luxembourg), healthcare professionals, public-sector communes and intercommunalités (notably CCPHVA for Cantebonne-Villerupt), and property investors (Pinel/PTZ-eligible). Go-to-market is sales-led and direct-to-consumer, supported by content marketing (corporate site, LCB'Immo blog, social media), events (Salon Viving Nancy, open houses), and a co-development partnership with FL Résidences for the Alsatian market. Buildings are designed to exceed RE2020 thermal/acoustic thresholds and target DPE A/B ratings, with select projects certified NF Habitat HQE.

Strategically, LCB is positioned as a regional niche player in sustainable construction, monetizing regulatory tailwinds (RE2020, energy transition) and local material provenance. Recent momentum includes a March 2026 partnership with FL Résidences for the Alsatian market, January 2026 inauguration of the Les Petits Robinsons micro-crèche, May 2026 design-office expansion, and a multi-year delivery pipeline through 2028. However, H1 2026 revenue declined 38% YoY (5.7M EUR vs. 9.2M EUR in H1 2025) due to social-housing contract signing delays, illustrating exposure to lumpy public-sector revenue despite management's expectation of an H2 recovery.

Direct peers

• Ossabois: Specialist French timber-frame construction company (part of GA Smart Building) focused on wood construction for residential and commercial projects. Closely aligned on the core construction technology (MOB / ossature bois) though operates more as a builder than developer.
• Realites: French real estate developer with explicit focus on sustainable and energy-efficient housing across regional France. Highly comparable business model combining residential development with eco-construction commitments and a similar geographic footprint outside major metropolitan areas.
• Coffim: Paris-focused French residential developer building apartments, houses, and mixed-use projects in regional France. Comparable for-sale residential developer with similar diversified product mix across housing types.
• Quartus: French eco-district and sustainable real estate developer with comparable focus on low-carbon neighborhood development and mixed-use ecoquartiers. Closely aligned business model with LCB's Eco'City approach and similar scale as a private specialist.

Broad incumbents

• Kaufman & Broad: Major French for-sale homebuilder operating across multiple regions with diversified product types (single-family, multifamily, managed residences). Comparable as a broad residential developer though much larger scale and not specialized in timber/eco-construction.
• Altarea: Listed French real estate group covering residential, retail, and commercial development. Comparable on multifamily residential and mixed-use projects, though it operates at much larger scale and is not specialized in wood construction.
• Vinci Immobilier: Real estate arm of the major Vinci construction group, developing residential and mixed-use projects across France with growing emphasis on sustainable construction. Comparable on eco-construction ambitions but operates at significantly larger scale as part of a construction conglomerate.
• Eiffage Immobilier: Real estate development arm of Eiffage Group, developing residential, commercial, and mixed-use projects across France with growing emphasis on RE2020-compliant and eco-construction. Comparable on the eco-development thesis though much larger and diversified.
