Completed in 1908, Joyce Grove Mansion is a large Jacobean style building designed by famous landscape architect Charles Edward Mallows (1864–1915) for Robert Fleming (1845–1933), founder of Robert Fleming and Co. merchant bank. Joyce Grove is listed Grade II on the National Heritage List for England.
As early as 1637 Joyce Grove, named for Cornet George Joyce, was sold to James Thompson of Wallingford.
By 1840, Joyce Grove was registered as a freehold estate of 33 acres belonging to John Toovey. London businessman H. H. Gardiner purchased Joyce Grove estate in 1894.
Joyce Grove estate, including a William and Mary style manor house dating from 1725, was incorporated into the main Nettlebed estate in 1895.
In 1903, Robert Fleming purchased the Nettlebed Estate which included 2000 acres, cottages, clayworks, and Joyce Grove estate with its manor house and land. Shortly after purchasing Joyce Grove, Robert Fleming tore down the older manor house and in its place he authorized noted landscape architect Charles Edward Mallows of Bedford and London to build a large Jacobean style house with 44 bedrooms and gardens. The main construction material was red brick with Bath stone dressings.
In 1908, the new Joyce Grove mansion and gardens was completed. The huge building and its grounds provided many jobs for residents of Nettlebed as gardeners, servants, and grooms.
On November 14, 1913 a fire at Joyce Grove mansion damaged the roof and the mansion was enlarged.
Robert Fleming's grandson, Ian Fleming, author of the James Bond novels, spent much of his childhood at Joyce Grove.
