The collection consists of architectural drawings by the architectural firms Burke, Horwood and White, and Horwood and White for the Hudson's Bay Company store building located at on West Georgia Street. The records principally document additions to the building, designed in 1925 and constructed in 1925 and 1926, which brought the building up to its modern footprint.
The collection includes preliminary, construction and as-built drawings pertaining to the 1925 addition and 1926 replacement of original 1893 building on the site. The drawings are primarily mechanical, HVAC, plumbing and electrical drawings, though the collection does contain some drawings of architectural designs. The drawings are depicted as floor plans, elevations, sections, details and schematic diagrams.
The drawings include reference copies of drawings from the construction of the 1913 addition to the 1893 store, the earliest part of the building still standing. The collection also includes a watercolour rendering of the store done at or after the completion of the building.
