In 1986-1987, the 1914 Lennox Building and the 1874 Millichamps Building were added to with a new structure which included an atrium between the two of them. This property’s contribution lies in its historic role in the establishment of Toronto Street as a corporate and financial hub in the late 19th and early 20th century, and its historic association with prominent early 20th century Toronto architect E.J. Lennox. The structures contribute to the physical character of the District through their Italianate architectural detailing and the transition they provide between the contemporary Financial District and the St. Lawrence neighbourhood.
