Carroll B. McCulloh and his wife Ella built this elegant two-story brick home in 1911 and raised their two children here. Its two-and-one-half stories, simple box shape, low-hipped roof, large central dormer, wide overhanging eaves, and offset front porch identify it as a Prairie style foursquare. Light-colored bricks decorate the eavelines, while dark bricks mark the corners in imitation of stone quoins associated stylistically with the Italian Renaissance. As the most popular house type in the 1910s, the foursquare was known for economy and efficiency because its straightforward layout maximized a family’s living space. That practicality and emphasis on comfort may have suited Carroll, who spent his career working to improve living conditions in Montana. During the 1900s and 1910s, he worked as a civil engineer helping modernize the infrastructure, especially sewer and water systems, of towns across Montana. In the 1920s and 1930s, he became a businessman, serving as secretary of an ice company and manager of the People’s Finance and Thrift. Carroll died in 1937, and Ella continued to live here through 1940.
