This is likely an early example (perhaps 1850s and no later than 1870s) of this form, judging by the entryway. The porch is probably a later addition. Hall-and-parlor and central hallway houses are related forms of the broader vernacular I-house family. Most I-houses I have encountered are two stories and better known in the South as Plantation Plain; they generally feature shed rooms. More documentation of this example is needed.
