Agency history

Our Architectural Practice was first established in 1973. The founding architects originated from Groupe Printemps S.A.
We formed a side company in 1981 for managing our architectural projects (société d’ingénierie).
When French law allowed architectural practices to be private limited companies, these two entities merged and became ERTIM Architectes, Société Anonyme d’Architecture.
Current managing executives are also majority share holders since 1992 when founding architects retired.

Didier POIGNANT –Président Directeur Général has worked with ERTIM Architectes S.A. from 1981 to 1983. He then created his own practice which has merged with ERTIM Architectes S.A. and became President in 1992.

Yves KERIHUEL –Directeur Général jointed the Practice in 1975 as junior architect. He progressively had increasing responsibilities and became General Manager of ERTIM Architectes S.A. in 1992.
