Atelier LWD was an architecture studio led by Guy Lagneau, Jean Dimitrijevic and Michel Weill that was active from 1952 to 1985. It later took the name of "Atelier d'Etudes Architecturales" (ATEA) (Architectural Studies Workshop) with the addition of Paul Cordoliani, Henri Coulomb (1927–2006), Renzo Moro and Ivan Seifert (1926–2008). The studio originated many public buildings in France and Africa.[1]
