Some projects become clearer with distance. In 2023, I created a 30th-anniversary mark for AGC Concept, the architecture and construction practice founded by Gérard Chaussignand in 1993. I have now rebuilt the project presentation to show not only the final symbol, but the design decision that made it belong.
Built from the same breaks
The established AGC letters are defined by open circular forms and deliberate interruptions. Instead of placing an unrelated anniversary badge beside them, I used those same characteristics to construct the numerals. The breaks behave like architectural joints and thresholds: each form remains distinct, while the eye completes a coherent whole.
The anniversary mark does not sit on top of AGC; it continues it.
The result marks a completed thirty-year span without becoming visually closed. That openness is the forward-looking part of the idea: a milestone can recognise everything already built and still leave room for what follows.
The photograph that completes the story
During my August 2026 visit, I met Gérard inside AGC’s Rovaltain headquarters and saw the 2023 anniversary mark in the place it was made for. The building itself reflects the practice’s history: AGC describes it as a laboratory and observatory created to improve energy performance and reduce environmental impact.
That moment is why the portrait belongs in the case study. It is not a staged application. It is documentary proof of the relationship behind the work—designer, client, identity, and place in the same frame.
AGC’s own history records the practice’s founding in 1993, its development of environmental engineering expertise, and the Rovaltain headquarters completed in 2006. These claims are sourced from AGC’s official presentation.
