Statement of Significance

Description of Historic Place

Located prominently on the corner of Burrard and Nelson Streets, south of Vancouver's downtown core, the Former B.C. Hydro Building consists of a 21-storey, distinctively-tapered, lozenge-shaped tower, framed by simple low wings along Burrard and Nelson Streets. The building is adjacent to the slightly earlier Dal Grauer Substation, and is set back from Nelson Street behind a vehicular drop-off.

Heritage Value

Constructed between 1955 and 1957, the Former B.C. Hydro Building is significant for its historical, symbolic, technological, and aesthetic values, particularly its role in making Modernist design prominent in downtown Vancouver, and helping place Vancouver design in the vanguard during these years.

The building is representative of a post-war economic expansion, which placed an emphasis on large infrastructure and resource extraction initiatives throughout the province, particularly hydroelectric power development projects.

Symbolic of the dynamic and prosperous future of British Columbia, made possible by its abundance of electrical energy, the building is a statement of the power and position of the B.C. Electric Company (later known as the B.C. Hydro and Power Authority) and its president A.E. Grauer. The building instantly became one of the most recognizable in the city and an icon for electrical development in the province, as a result of company policy to leave the office lights on all night. The resulting beacon of brilliance advertised the core nature of the company - electrical energy - and modern materials and lighting technology.

Designed by the city's pre-eminent architectural firm Thompson Berwick & Pratt, the building was a local development in the Modernist idiom, incorporating a fashionable lozenge-shaped tower floor plate with sophisticated idiosyncratic detailing, colouring and ornamentation informed in part by the architects' collaboration with the prominent local artist B.C. Binning, one of the founders of the influential Art in Living Group. Modernist principles of health and comfort are reflected in the design’s concern with adequate space, light and ventilation.

Typical of Modernist design practice at the time, the tower possesses an innovative structure, designed by Otto Safir, an engineer representative of the influx of European-trained professionals displaced by the events of the Second World War.

The aesthetics of the building, both inside and out, are a sophisticated integration of materials, detail and overall design, which dramatically engages the vertical tower with the simple horizontal wings and entry. Exterior details, such as the use of interior terazzo flooring, exterioir plantings, and mosaic tile are intended to harmonize with the grey, green and blue landscape of the west coast.
