Description du lieu patrimonial

The Gibson Block is large wedge-shaped four-storey brick building constructed in 1913. It occupies four lots of a triangular block on Jasper Avenue at the eastern edge of Edmonton's pre-World War One commercial core.

Valeur patrimoniale

The Gibson Block is valued as a rare example of a commercial building in the flatiron style, so named for its distinctive triangular shape, and as structural evidence of Alberta's commercial boom in the early years of the twentieth century.

The flatiron design, which originated in New York in 1902, was popular in North American cities prior to World War One as a way of using oddly-shaped parcels of real estate. The Gibson Block also incorporated elements of the Chicago style (notably its characteristic vertical emphasis of pilasters and windows contrasting with a horizontal motif in continuous glass shop fronts and cornices) as a visual statement of confidence in the new city's ability to rival those of the East. The most prominent of the commercial buildings in Jasper East Block area (96th and 97th Streets), the Gibson Block has been an important landmark in downtown Edmonton.

Developed by William Gibson, the building has mirrored the changing fortunes of the city's commercial district. It originally housed retail space on the first floor, offices on the upper floors, and a Turkish Baths in the basement, though the upper floors were converted to apartments in 1914.
