The grounds associated with Overthorpe Hall consist of parkland that has been modified for recreational purposes and some informal planting, parts of which may date back to the 19th century. The Hall has been a school since the 1940s.
The parkland, house and informal gardens were in existence by the first edition Ordnance Survey map dating back to the 1880s. There was an informal planting of trees and shrubs around an oval drive by this time. The 1880s map also shows a range of other buildings, such as stables, many of which are no longer standing. It is not clear whether there was any activity on the site in the 18th century.
