Petitcarrée Architectes Sàrl is an internationally oriented architectural practice recognised for its commitment to public architecture, architectural competitions, and concept-driven design. The office approaches architecture as a collaborative process, where research, context, and critical thinking form the basis of every project.

Working within this environment provided valuable insight into the development of public buildings through the early design stages, from the formulation of architectural concepts to the refinement of competition proposals. A significant part of this experience was the competition for the Bâtiment scolaire avec maison relais à Strassen, where the design proposal was awarded 3rd Prize. The project encouraged the exploration of architectural ideas while contributing to a collaborative design process within an international team.

The experience reinforced the importance of conceptual clarity, architectural dialogue, and design culture, demonstrating how thoughtful architecture emerges through the continuous refinement of ideas rather than predefined solutions. These principles remain fundamental to the way AAAB approaches every design challenge.
