Anchored in Québec City’s Old Port, the headquarters of Groupe Desgagnés stands as a testament to both history and renewal. This project sought to restore clarity and coherence to an ensemble composed of two buildings — one dating from 1911, the other from 1960 — linked by a connecting walkway that establishes an architectural dialogue between them. The 1911 building was given a new copper roof, while its original turret, truncated in the 1970s, was boldly reinstated at the client’s request and reconstructed as part of the project. Clad in copper, the turret once again asserts its distinctive silhouette, enhancing the building’s architectural dignity and re-establishing its presence within the historic urban landscape. The connected 1960 building also underwent a significant transformation. Its curtain wall now incorporates refined copper accents, including new fascias and rooftop mechanical screening. The reconstructed link between the two buildings continues this material strategy, integrating copper into both the curtain wall system and the enclosure of technical equipment, resulting in a renewed architectural harmony. Finally, two new canopies mark the primary entrances to the buildings. Elegantly designed, they likewise incorporate copper elements, serving as a unifying material signature that reinforces architectural cohesion and enriches the experience of arrival.
