Corbar Hill House (on Corbar Road in Buxton) is a Grade II listed building. It was built in the 19th century in the style of a French château (with a mansard roof and fountain), apparently for the Ryder family. It later became John Duncan School, which closed in 2003. It has now been converted into private apartments. Corbar Hill Hydro was converted from the Clarendon guest house in the 1890s to offer hydropathic treatments. It was sold in the 1930s for nurses' accommodation.
