What Willy Naessens Industrial Buildings NV does

Willy Naessens Industrial Buildings NV (NV Willy Naessens Industriebouw) is a family-owned Belgian industrial building contractor headquartered in Wortegem-Petegem, with operating subsidiaries in France, Luxembourg, the Netherlands, and Denmark. The firm positions itself as the market leader for industrial buildings in Belgium and Luxembourg, citing more than 10,000 completed projects since the founder began building barns and swimming pools in the 1970s and the concrete business was established in 1982. Customers include logistics operators, retailers, manufacturers, real estate developers, food processors, and public-sector buyers, served through a regional direct-sales model with technical-commercial representatives covering each Belgian province and adjacent markets.

The company's core offering is vertically integrated prefabricated concrete construction. Twelve in-house factories produce structural columns, IV-liggers and BX-liggers prestressed beams, TT roof elements, WX prestressed floor slabs, and insulated sandwich wall panels; the group also operates its own aluminum joinery (Willy Naessens Alu), roof waterproofing, ground and environmental works (Willy Naessens Infra), foundation teams with HSP piling and vibration-free screw piles, transport fleet, BIM-enabled design bureau, and assembly teams with more than 30 cranes. Construction formulas span Casco (structural shell), Turnkey (sleutel-op-de-deur, fully finished), Design & Build (collaborative from pre-design), and the 2024-launched The Circle® concept — a registered modular system of 100 demountable concrete blocks with a 3D design tool and targets of 70% element reusability and BREEAM Excellent to Outstanding certification.

Revenue is generated on a project-based, quote-by-project basis under multi-year contracts ranging from Casco shells to fully finished turnkey buildings. The firm sells directly to enterprise customers via nine regional representatives and dedicated specialists for The Circle® and Design & Build, supported by a Dutch-language website, a newsletter, and industry-event presence. It holds the Agoria/Sirris Factory of the Future label (2024, aluminum division) and the CO2logic Taking Climate Action Bronze climate certification. No external funding rounds, parent company, or public ticker are disclosed; the entity remains a family business with no recorded private equity or venture capital ownership.

Core offering

Willy Naessens Industriebouw designs, prefabricates, and constructs industrial buildings using its own concrete elements produced across 12 own factories. Delivery is offered through four formulas: Casco (structural shell), Turnkey (sleutel-op-de-deur fully finished building), Design & Build (collaborative design-to-construction), and Prefab Building. The proprietary The Circle® concept offers 100 modular, demountable concrete blocks enabling industrial buildings to be designed in 2 hours with real-time cost indication.

Product overview

Willy Naessens Industrial Buildings NV is a vertically integrated industrial building contractor headquartered in Wortegem-Petegem, Belgium, operating across Belgium, Luxembourg, and the Netherlands. The company offers a portfolio of construction formulas — Casco (shell), Turnkey (full turnkey), Design & Build, and Prefab Building — alongside its flagship circular building concept The Circle®, which consists of 100 modular, demountable concrete building blocks enabling industrial buildings to be designed in 2 hours with real-time cost indication. The company's core differentiator is its vertical integration across 12 own factories, producing all structural elements (columns, beams, insulated wall panels, TT roof elements, WX slabs, IV-liggers, BX-liggers), as well as ancillary divisions covering own concrete factories, aluminum joinery (Willy Naessens Alu), roof waterproofing, ground and environmental works, transport, assembly teams, a design bureau with BIM/R&D capabilities, and interior finishing. Sector-specific building solutions serve SME, logistics/distribution, retail, food, public, office, sports/recreation, and parking garage segments.

• Turnkey (Sleutel-op-de-deur) Full turnkey industrial building delivery where the structure and exterior finish are complemented by groundworks, building techniques, and interior finishing, with the building handed over fully operationally ready for use.
• Design & Build Integrated design and construction approach where close collaboration begins from the pre-project phase between the client, the industrial building architect, and Willy Naessens Industriebouw, with overlapping design and construction phases creating synergy.
• Prefab Building Prefabricated concrete building system where all structural elements for a project are produced and assembled in-house, ensuring execution speed and punctuality.
• The Circle® A groundbreaking circular concrete building concept consisting of 100 modular, demountable building blocks that can be combined to create any industrial building. Uses a 3D design tool to generate a modular design in 2 hours with real-time cost indication. 70% of elements are reusable without modification, 25% fully recyclable. Targets BREEAM 'Excellent' minimum score.
• Prefabricated Industrial Wall Elements Prefabricated concrete wall elements available as solid walls (min. 14 cm thick) for plinths, retaining walls, interior walls, and fire walls, and as insulated wall elements with outer reinforced concrete layer, insulation core (PS, PU, PIR, RESOL), and inner concrete layer.
• TT Roof Elements Prestressed concrete TT roof elements consisting of 3 ribs with 800 mm center-to-center spacing connected by a 35 mm compression slab, modular width 2400 mm, variable length up to 12.60 m, total height 330 mm, concrete quality C50/60.
• WX Prestressed Concrete Slabs Prefabricated prestressed concrete floor elements used in applications requiring large spans, heavy loads, and/or small construction heights, manufactured in a closed production space with smooth underside from heated formwork.
• IV-Liggers (Prestressed Roof Beams) Prestressed concrete beams used as roof girders where the slope provides drainage; variable height allows significant material savings and offers the most economical solution for spanning industrial buildings.
• BX-Liggers Prestressed concrete beams providing a solution when reinforced concrete beams do not meet specific load requirements.
• Foundation Services Foundation solutions including pad foundations for shallow bearing layers and pile foundations for deep bearing strata, with proprietary HSP pile driving and four vibration-free ground-displacing screw pile machines operated by own specialist teams.
