The rear ell was built in the late 1840s and the front block around 1880.","why_significant":"The nomination argues the house is the only surviving nineteenth-century dwelling in Granville County in the Carpenter Gothic and Italianate styles, with the county's most ornately carved woodwork. It is also valued for its craftsmanship, its intact condition and its rarity. It reflects the county's plantation era and the later bright leaf tobacco farming era.","narrative":"Near Grissom in Granville County, this frame house combines two building campaigns. The two-story rear ell was built in the late 1840s by Joseph B. Allen, a planter who bought his land in 1844, and it keeps plain Greek Revival mantels and doors. The front block, apparently built around 1880 by H. D. Mangum after he gained sole rights to the property, is a two-story I-house with a center hall. Its gables, brackets, triangular window caps and especially its front porch carry intricate cutout woodwork in Carpenter Gothic and Italianate style. Inside, the front rooms have wainscoting, Gothic pointed mantels, carved stair ends and a carved newel post. The nomination calls it the only surviving nineteenth-century house of this type in the county. It began as a plantation seat and later became the center of a bright leaf tobacco farm. A family cemetery east of the house holds the graves of Allens and Mangums, beginning with Joseph B. Allen, who died in 1854. The nominated area covers about 3.5 acres.","period_of_significance":"late 1840s-1937","architect_builder":"Unknown; the front block was apparently built by H. D.
