The Warren Bank Board of Directors chose English-born architect Richard Alfred Waite (1848–1911) to prepare the plans for this flatiron building on the most prominent site in Warren. Known for designing insurance company office buildings in his home base of Buffalo, as well as in Toronto and Montreal, he came to the United States in the 1850s and studied to be a mechanical engineer in New York City, switching ultimately to the architectural firm of John Kellum. Waite secured his reputation in 1885–1893 when he designed Ontario's parliament building. A hexagonal clock tower with a copper roof marks the point of this triangular, four-story brick bank. Foliated brownstone carving ornaments the tower's triple-arched windows and a graceful staircase leads to the corner entrance.
