How Hill House is a large Edwardian house in How Hill, an area of Ludham parish, Norfolk, England. The house overlooks the River Ant and is within the Broads National Park. The house was designed by the English architect Edward Boardman in 1903, who intended it to be his family's country retreat. The Boardman family owned the house until 1966 before its sale to Norfolk County Council. Years later it was sold to Norwich Union who eventually gifted the house to the How Hill Trust, an environmental education charity. The house is a Grade II listed building.
