Sewickley Manor
Also known as: Pollins Farmstead
Why it's listed
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.
Significance in brief: 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.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
