Colonel Robert Dormer-Cottrell, the grandson of the house's builder, inherited Rousham in 1719 and began the huge transformation of the gardens to its current appearance. Initially he employed Charles Bridgeman to lay out the gardens in the new and more naturalistic style that was becoming popular. Bridgeman's layout of the garden was completed circa 1737. Rousham was then inherited by the Colonel's brother, General James Dormer (1679–1741), who called in William Kent to further enhance and develop the garden that Bridgeman created. This Kent did with considerable success over the next four years.
