This landmark industrial building was designed by Chicago architect Max Dunning and the Toronto firm of Burke, Horwood, and White. In later years, matching additions were built to the north. Originally serving as a warehouse, manufacturing, and administrative building for the Robert Simpson Co. mail-order business, it also became the first headquarters of Simpsons-Sears (later Sears Canada) in 1952. In the late 1990s, the building was converted to residential lofts.
