In the early 18th century the Oulton Estate was home to the Egerton family and comprised a manor house and a formal garden surrounded by farmland in Cheshire, England. Later in the century the farmland was converted into a park. The estate is now the site of the motor racing track called Oulton Park.
In 1731, Philip Egerton (1694–1766) inherited the estate upon the death of his uncle, John Egerton (1656–1731). At that time the estate comprised a house, a formal garden and farmland totaling 231 acres (0.93 km2). Around 1752, Philip Egerton began to construct a brick wall to enclose the estate plus some additional fields, an area totaling 315 acres (1.27 km2). At his death in 1766, Philip was succeeded by his brother John, and then in 1770, by his son Philip (1738–1786). By this time the fashion for formal gardens had been overtaken by the concept of a landscaped garden with surrounding parkland. Philip Egerton commissioned William Emes to plan this for his estate. Eme's plan was produced about 1770, but the work was still in progress 10 years later. The plan was to do away with the formal garden, to divert the brook and by building dams, to create two lakes connected by a cascade. A banqueting hall was to be built on an island in the larger lake. There was to be extensive planting of trees and shrubs. The park was to include a bowling green, gravel paths and a boathouse.
In 1715, John Egerton commissioned the building of the new house. Tradition has it that the previous Tudor house had been destroyed by fire. The new house was in Baroque style. Its main front was in 15 bays, the middle three bays being occupied by a Corinthian centrepiece, its pediment filled with carvings of trophies. A drawing exists showing a central dome, but if this dome, in fact, ever existed it did not survive to the 19th century. On the sides were curved pediments. The entrance hall rose through the building's two storeys. It contained Corinthian pilasters and had a plaster groined vault. Around 1773, the gates and gatepiers which had been built around 1725, were removed to St Oswald's Church, Malpas. They were replaced by an entrance lodge comprising an arch with screen walls designed by Joseph Turner. In 1786, the house was inherited by John Egerton (1766–1825). He and his successors did carry out some improvements during the 19th century. Between about 1816 and 1820, Lewis Wyatt altered the interior, added stables and a terrace. In 1926, the house was destroyed by fire, and in 1940, it was bombed.
