Mansfield founder Ralph S. Man built this home for his family between about 1865 and 1870. The oldest known building in Mansfield, it became an important local landmark as Man enlarged and remodeled it over five years from a one-room frontier log house into a comfortable upper middle-class residence. Colonial Revival, Greek Revival, and Queen Anne influenced detailing appears throughout the house. The home began as a one-room log house built about 1865. In 1867, Man added a second, brick section on the east side containing a parlor and dining room, with an open dogtrot or breezeway between the two parts. Around 1870, he enclosed the breezeway and added a second story with three bedrooms. The final addition came in the 1930s, when the rear porch was enclosed to create a service porch and bathroom. The house's woodworking reflects Man's early training as a carpenter in the original oak floors, baseboards, window and door surrounds, interior wood doors, walnut stair handrail and newel post, and mantels that remain in the home. In 2020, the city of Mansfield restored the house to stabilize the historic structure and remove some modern modifications, replacing a modern metal roof with a shake shingle roof like the original, building a new fieldstone chimney on the west side in place of the original that had fallen before 1968, painting the interior rooms in their original colors, and exposing the logs of the original log house. Today, the house looks much as it did when the Man family lived there.
