Peter Harvey House and Barn is a historic home and barn located in Pennsbury Township, Chester County, Pennsylvania. The original house was built between 1773 and 1777, and is a 2 1/2-story, three bay by two bay, stone dwelling with a gable roof. It has two interior gable end chimneys and a front porch added in the early 20th century. The house was expanded in 1940, with a two bay extension added to the house making it five bays wide. At the same time, a smaller two-story, stone and frame addition was built onto the east gable end.
