Jacobs, with a carriage house and a small round brick outbuilding.","why_significant":"The house is significant for its architecture, especially its 19-foot-diameter three-story corner tower, and for Felix Jacobs' role in local industry and politics. Jacobs co-founded the Kilbourne and Jacobs Manufacturing Company and, as Director of Public Improvements, was largely responsible for the Jacobs Conduit, the city's first source of safe drinking water. The house also was a showplace of up-to-date heating, electrical and telephone systems.","narrative":"Built between about 1905 and 1910, this thirty-room gray brick house at 1421 Hamlet Street in Columbus was home to Felix A. Jacobs, his brother and his sister. Its dominant feature is a 19-foot-diameter round corner tower rising three stories under a conical roof, with a concentric porch at its base. A carriage house and a small round brick outbuilding stand nearby. Jacobs co-founded the Kilbourne and Jacobs Manufacturing Company, a maker of wheelbarrows, scrapers and other earth-moving equipment sold around the world. While serving as Director of Public Improvements in 1897-98, he had an iron conduit built to supply the city with artesian well water, relieving a water shortage. The house originally featured an electric telephone system and a double furnace and boiler. Later divided into apartments, it now serves as a youth crisis center, though its first-floor interior details remain largely intact.","period_of_significance":"1900- (specific dates c. 1905-1910)","architect_builder":null,"architectural_style":"Queen Anne (noted in the reviewer's comments)","criteria":["B","C"],"status_note":"Occupied; used as a crisis counseling center and shelter for troubled youths.
