What Group Jansen does

Group Jansen is a privately-held Belgian integrated construction group, headquartered in Zonhoven, founded in 1972 by five brothers and currently led by CEO Nadia Jansen. The company operates across three pillars: Makers (proprietary manufactured products including J'Clickd circular system walls, J'Sky climate ceilings, prefab elements, custom joinery, cleanroom products, and Vinitex laboratory furniture), Builders (general construction, decoration, HVAC, electrotechnics, smart building automation, and cleanroom construction delivered under a design & build model), and Sustainers (24/7 multi-technical corrective, preventive, and predictive maintenance via Jansen Services, performing 50+ interventions daily). It serves enterprise clients across healthcare, hospitality, retail, offices, education, industry, and life sciences through direct enterprise field sales, with 750+ employees and 13+ wholly-owned subsidiaries operating from nine locations across Belgium, the Netherlands, and Germany.

Revenue is generated through three streams: project-based design & build contracts (typically multi-month to multi-year, quote-based, durations from 3 months for an 850 m² office fit-out to 1.5 years for a 5-floor law firm transformation), proprietary product sales (J'Clickd, J'Sky, prefab, cleanroom components), and recurring maintenance subscriptions. The company markets itself primarily through an extensive website portfolio, LinkedIn, Instagram, and YouTube, and pursues certifications including ISO 9001:2015, VCA** 2017/6.0, and BREEAM/WELL-aligned products.

Underlying technology centers on full BIM methodology (with a publicly available BIM configurator), point cloud scanning, 3D and VR visualization, clash detection, and a centralized smart building automation platform. Vertical integration — owning R&D, design (LUBDUB), manufacturing, installation, and maintenance — is positioned as the primary differentiator against fragmented multi-contractor construction models.

Direct peers

• BESIX: Belgian-headquartered international construction group with strong presence in Benelux, Middle East and Africa. Comparable to Group Jansen as a Benelux-anchored construction company with multi-disciplinary capabilities, though far larger and more internationally diversified.
• BAM Group: Dutch-listed construction group with integrated design, build and maintenance offerings across the Benelux market. Directly comparable in vertical integration (construction + maintenance) and in addressing healthcare, office and infrastructure clients with sustainability-certified solutions.
• Maars Living Walls: Dutch manufacturer of modular and demountable wall systems for offices, healthcare and education. A direct product-level peer for Group Jansen's J'Clickd circular system walls, competing in the same modular partition category across Europe.
• Willemen Groep: Belgian family-owned construction group with integrated building, civil engineering and interior divisions. Closely comparable to Group Jansen's vertical integration model and Benelux geographic focus, though larger in scale and more diversified into civil works.
• Heijmans: Dutch integrated construction and real estate developer active across residential, non-residential and infrastructure. Comparable to Group Jansen in providing integrated Design & Build plus lifecycle services, though larger and more diversified into residential development.
• CFE (Compagnie d'Entreprises CFE): Listed Belgian construction and multidisciplinary group operating across construction, real estate development and concessions. Comparable to Group Jansen as a Benelux-rooted general contractor but with significantly greater scale and a public-market capital base.

Broad incumbents

• Skanska: Swedish-headquartered global construction and real estate development group with strong sustainability credentials. Comparable to Group Jansen in delivering BREEAM/WELL-certified commercial projects for enterprise clients, though far larger and more internationally diversified.
• Reynaers Aluminium: Belgian-headquartered European leader in aluminium building envelope systems (windows, doors, facades). Comparable to Group Jansen as a Belgian premium building-systems specialist, though operating at much greater scale and on the building envelope rather than interior fit-out.
• Knauf: Global family-owned manufacturer of building materials including ceiling systems, drywall and insulation. Comparable to Group Jansen's Ceiling Solutions division and J'Sky climate ceilings as a building-systems supplier, though operating as a materials manufacturer rather than integrated contractor.

Others

• Saint-Gobain: French global leader in light and sustainable construction materials including ceilings, insulation, glass and gypsum. An adjacent supplier rather than direct competitor, but its ceiling and interior-systems divisions intersect with Group Jansen's Ceiling Solutions and J'Sky climate ceiling product line.
