Barclay House, also known as the Joshua Hartshorne Estate, North Hill, and The Barclay, is a historic home located in West Chester, Chester County, Pennsylvania. The original section was built in 1866–67, and believed to have been designed by noted architect Addison Hutton (1834–1916). It was a 21⁄2-story, brick dwelling in the Italianate style. It was expanded to three stories with the expansion of 1935–36. Also added at that time was a three-story connecting block, three-story west block, and one-story north block. The house was also renovated in the Colonial Revival style. The north block was expanded to two stories in 1998. Also on the property is a contributing carriage house built in 1869. It was converted to a residence in 1925. It was built as a single family residence, but converted to a Quaker boarding home for the elderly in 1935-1936. The boarding home closed at this location in 1997.
