The present hall was built in 1825–30 to the designs of Robert Smirke for Sir Robert Sheffield (1786–1862). The Sheffield family had lived on the site since 1539 and the family's titles include Dukes of Buckingham and Normanby and Sheffield baronets. It replaced a previous 17th century building.
John Sheffield became Duke of Buckingham and Normanby in 1703. He built a fine mansion in London called Buckingham House. His son, the second Duke sold the house to George III and it is now known as Buckingham Palace.
The house was extended and altered to designs by Walter Brierley between 1906 and 1908.
The Sheffield family moved out of Normanby Hall in 1963. The hall is now in the care of the North Lincolnshire Council. The former 350 acre (1.4 km²) estate around the hall is now a country park. Within it, there are a restored working Victorian walled garden, a farming museum, duck ponds, a deer sanctuary, a fishing lake, a miniature railway and a stableyard with the life-size Horse and Rider sculpture by Harold Gosney,.
