What Les Entreprises Louis De Waele does

Les Entreprises Louis De Waele is a Belgian construction and real estate group founded in 1866 and headquartered in Watermael-Boitsfort (Brussels). The group operates three integrated entities: Louis De Waele Construction (general contracting for buildings and civil engineering, with in-house integrated engineering covering planning, methods, structural stability and special techniques), Louis De Waele Immo (residential and mixed-use property development focused on Brussels and Walloon Brabant, including projects such as Starcity, Goujons Citydev and Corniche D'Or), and Entreprises Simonis (high-end bespoke renovation). Notable executed projects include the new Jules Bordet oncology center for ULB (250 beds, 2020), the ING Marnix Passive House/BREEAM Outstanding headquarters (2024), multiple Brussels metro and railway stations (STIB/MIVB, SNCB), the Brussels Airport Skyhall II facade, the European Commission Berlaymont Welcome Center, and the Befimmo Central Gate office renovation.

The business is project-based and B2B, generating revenue through fixed-price construction contracts (public and private), real estate development sales (Immo), and specialized renovation mandates (Simonis). Commercial activity is driven by direct enterprise sales, public procurement bidding, and long-term relationship management with government, institutional and corporate clients. Pricing is not publicly disclosed and is determined via competitive tendering or direct negotiation. The technology stack centers on BIM and 3D-REVIT for design and execution, with no disclosed AI/ML, API or data-platform capability.

Since 2013 the firm has been wholly owned by Rabot Dutilleul, a Top 10 French construction group (~€700M revenue, ~1,900 employees, 80% family-owned). The group holds ISO 9001, 14001 and 45001 certifications (renewed November 2025 through September 2027), operates with 250 employees, and reported €140M in revenue for 2022 (French group page; the Dutch version reports €120M). Operating geographies are limited to Belgium (Brussels-Capital, Flanders and Wallonia).
