609 Granville Street, a 25-storey commercial office tower in downtown Vancouver, was showing its age and needed an envelope upgrade. Constructed in 1981, the building interconnects with the three-block long Pacific Centre Mall in the city’s main business district. The owner, Cadillac Fairview, was motivated to not only address the poor envelope performance, but to update the tower’s appearance to match its triple-A location—all with minimum disturbance to the building’s tenants.
The design team proposed a full glass replacement with small but effective interventions that improved both the building’s technical performance and interior environment quality, while updating its aesthetic relationship to the cityscape. In addition to lightening the glazing colour, the team transformed the tower’s expression from horizontal to vertical: highlighting the top floor with a crown of narrow, delicate lines of white light.
The result is a building with improved performance, a coherent new look, and clear identity during the day and night in contemporary Vancouver.
