Kelvin
Why it's listed
Kelvin is a two-story Federal style house in Pittsboro, Chatham County, built by 1831 as a private girls school by Colonel Edward Jones, a lawyer and landowner who had moved to the county in 1801. The house has a gable roof, exterior end chimneys and a single-pile plan, with a one-story north addition dating to about 1838. Its interiors are the main reason for its listing. The mantels, which combine molded architraves, panels and a shaped Ionic-derived surround, are regarded as the finest of their period in the town, and the enclosed quarter-turn staircase and sheathed wainscoting reflect the work of a skilled regional craftsman. The house also represents the girls' schools that were established in Pittsboro in the 1830s, when the town was growing. Later owners included physician and legislator Spence McClenahan and the nurseryman Claudius B. Denson, who ran a botanical nursery on the grounds.
Significance in brief: The nomination argues that Kelvin is the finest example of the regional Federal style in Pittsboro, noted for its enclosed staircase, sheathed wainscoting and well-proportioned mantels. It is also tied to the town's private girls schools, which the nomination says influenced women's education in North Carolina, and to Edward Jones, a lawyer and politician.

What listing means for this property
National Register listing is honorary: it recognises significance and does not restrict what a private owner may do without federal money or permits.
