The estate includes a residential grouping with outbuildings on forty-three acres and a farm complex on eight and one-half acres.","why_significant":"The nomination argues the estate is significant for its architecture, as a well-preserved early twentieth-century summer estate commissioned by a wealthy Pittsburgh family. It states the manor house retains much of its original Shingle style design and that the estate keeps more of its original acreage and outbuildings than other estates in the borough.","narrative":"Built between 1899 and 1900 by the Pittsburgh steel brokerage executive William Penn Snyder and his wife, Mary Cuddy Black Snyder, Wilpen Hall is a three-story sandstone and shingle manor house in Sewickley Heights. Designed by the Pittsburgh architect George S. Orth, it has a gambrel roofline on the east end, a porte cochere on the west, and porches of rectangular stone columns on the north and east. A west addition of about 1925, probably by Robert Maurice Trimble, extended the house. Its importance lies in its design as an early twentieth-century summer estate in the Shingle style, which was popular with wealthy Pittsburgh families in the area. The estate retains a large share of its original forty-three acres of grounds, a barn, farmhouse and cottages, and it is the only remaining great estate in the borough still owned by the family that commissioned it.","period_of_significance":"1899-c.1925","architect_builder":"George S.
