In 1827, Sir George William Jerningham, 8th Baron Stafford, commissioned large-scale grand and elaborate expansions of Sir Henry's Hall, with many towers and mock-Tudor windows. The project was ongoing over several decades, continued by the 9th Baron Stafford from 1851, and although many features of the new design were realised, completion was ultimately prevented by dwindling funds. The 10th Baron Stafford, who inherited the title in 1884, was certified as a lunatic; during his ownership, the estate was held by the Lunacy Commission. The generous and reclusive Sir FitzOsbert Stafford Jerningham, 11th Baron Stafford, resided at Costessey Hall until his death in 1913, upon which the Hall's contents were auctioned at a high-profile sale.
Costessey since 1913
The final owner of the empty but intact building was the War Office, who commandeered the Hall from 1914-18 for the training of infantry, cavalry and artillery troops to serve in World War I. Soon after war ended, Costessey Park was divided into small plots sold cheaply to working-class residents of Norwich, who erected makeshift wooden houses or brought disused railway carriages as their dwellings. The well-trodden paths amongst these plots became the basis of a street network, and the ramshackle homes gave way to brick buildings during the 1930s - 1950s, to become New Costessey. The street names of Jerningham Road and Stafford Avenue honour the local associations with the aristocratic family.
The structure of Costessey Hall was gradually weathered, plundered by builders, and carefully demolished over a period of several decades. During training for World War II, one of the towers was struck by a fully-armed Blenheim Bomber from a nearby airfield, causing the death of the unfortunate pilot but inflicting remarkably little damage upon the tower. Today, all that remains of the building is the belfry tower and a small adjoining block, which stand prominently in what is now Costessey Park Golf Course.
