The main house was built in 1852 by David S. Pollins.","why_significant":"The nomination argues that the farmstead is a well-preserved example of a mid-19th century Western Pennsylvania farmstead, with the house a fine example of the Western Pennsylvania adaptation of the Greek Revival style. It is also described as unusual in western Pennsylvania for retaining all its supporting outbuildings, and the barn is presented as a fine preserved example of an earlier agricultural era.","narrative":"Built in 1852 by David S. Pollins, the two-story brick house at Sewickley Manor sits among large shade trees in the Westmoreland County community of United, Pennsylvania. Its common-bond brick walls, hipped roof, dentilled cornice and heavy stone lintels follow the Western Pennsylvania form of the Greek Revival style, which was common in the region from about 1830 to 1860. A two-story frame addition on one side elevation makes the five-by-two bay plan nearly square. The farmstead includes a barn built in 1849, a tenant house dating from before 1900, and a smokehouse from about the 1790s, along with other outbuildings from the 1800s and 1880s. The land was acquired in 1796 by Abraham Leasure, who lived there until 1805, and some outbuildings date from his ownership. The Pollins family has held the property for seven generations.","period_of_significance":"1852","architect_builder":"David S.
