The Studio Building
In 1913-1914, painter Lawren Harris and art patron Dr. James MacCallum financed the construction of the first purpose-built artists' studios and residence in Canada, a building intended to foster the development of a distinctly Canadian style of painting. Designed by Eden Smith, the light factory construction exemplifies the simplicity of early modern architectural design. For decades, many distinguished artists have worked and lived in the Studio Building, most notably Tom Thomson and members of the Group of Seven.
