What Syntax Architects does

Syntaxe Architectes is a Belgian private partnership architecture firm founded in 2004 by Joël Meersseman, Ronald Rifflart, and Rénald Pansaerts, headquartered in Haut-Ittre (Walloon Brabant) with additional offices in Tilff-Esneux (Liège) and Dunkerque (France). The firm operates with approximately 38 professionals including architects, a dedicated Revit Referent, a BIM Coordinator, and Level A Safety Coordinators, offering full-lifecycle architectural services across residential, commercial, industrial (notably pharmaceutical/SEVESO), public infrastructure, and urban masterplanning. The 2019 acquisition of Atelier du Sart Tilman (AAST) extended the firm into the Liège region and brought Daniel Boden into the partnership, adding urban planning and tram infrastructure expertise.
