Brutalism was a response to the glass curtain wall that was overtaking institutional and commercial architecture in the 1960s. The style originated in England but was quickly introduced to Ontario as it afforded an attractive and relatively inexpensive solution to weather and climate control conditions in large buildings, as well as a finish that was less vulnerable to vandalism. The 1960s and 1970s were years of great expansion in universities and public buildings, and this is where the Brutalist style is most often found. The development of béton brut, a concrete with no formal finish, was intrinsically linked to this style. When the formwork is lifted from the poured concrete, the rough, naturally textured surface is the final finish. The amount of texture on the surface is dependent upon the amount of texture on the formwork. The smooth texture of glass for windows and doors forms an attractive contrast. Most windows in Brutalist buildings do not open and the buildings are thoroughly climate- controlled. The design of the building is largely dependant on the shape and placement of the various room masses. Outlines are quite intricate and exterior walkways are emphasized.
