Photograph of a long, two-storey office building with a white clapboard exterior, established as temporary offices for the Canadian war effort. A piece of paper adhered to the verso describes this structure as "Temporary Building No. 1".

Interior and exterior views of the building. This office building has a 'green roof', which reduces the amount of energy required to heat and cool the building. It also has an extensive shopping mall at the ground floor and an arboretum with a waterfall at the Queen Street entrance. The double-decker elevator cabs are found inside the atrium, which stretches the entire height of the building.
