Constructed between 1954 and 1958, the West Memorial Building is a prominent federal heritage landmark along Ottawa’s ceremonial route. Designed as a paired composition with the East Memorial Building, the ensemble expresses its intent through formal massing, axial planning, and the linking Memorial Colonnade. Because it has been designated a Classified Federal Heritage Building for its historical, architectural, and environmental significance, all interventions are guided by rigorous heritage standards. As part of a comprehensive rehabilitation and modernization program, the project prioritized the conservation and renewal of the building envelope while preserving defining heritage elements. Targeted upgrades were undertaken to improve durability and performance without compromising its historic character.

Central to this work was the renewal of the building’s copper roofing and associated assemblies, with new sheet copper fabricated and installed using traditional batten-seam detailing. Custom copper flashings, parapet caps, and coping details were crafted to resolve complex roof geometries and transitions, with lead-coated copper used at stone interfaces to ensure long-term material compatibility. Copper finials were carefully replicated from original details, while discreet custom bronze snow guards were incorporated to address snow-retention requirements without detracting from the roof’s historic character. The dormers were fitted with custom louvers designed to meet ventilation requirements and integrate seamlessly within the building’s architectural language.

The copper work was executed to an exceptional standard of craftsmanship, with meticulous attention to detail and technical resolution. Original, complex curved profiles were expertly replicated, along with jointing and ornamental details, using traditional techniques. Carefully considered refinements were introduced to improve performance, durability, and long-term resilience. The resulting work demonstrates a high level of craft and technical expertise, supporting both the building’s heritage character and its ongoing contribution as a prominent federal landmark.
