A moated house as the manor house existed by 1538. It was described in 1649, probably with the remnants of the moat, and was depicted in 1749 as a large, apparently L-shaped building with a central cupola. It appears to have been rebuilt in the third quarter of the 18th century and by the time of Lady (Sarah) Salusbury was a three-storeyed villa with a central canted entrance bay rising the full height of the north front. A lower wing, presumably an addition, ran southward from the east end. In 1789 Humphry Repton landscaped roughly  of demesne grounds and William Wilkins supplied drawings for a Gothic seat. In his Red Book Repton commented favourably on the hilltop site and enhanced the view towards London. The house and 23 acres, increased by 1834 to 53 acres, was occupied by Trotter baronets (1804-36), Lady Trotter (1836-40), Lady (Elizabeth) Salusbury (1840-3), and Charles Hambro (1843-9). The house was extended westward and a semicircular bay was added to the south front in the early 19th century. By 1849 the demesne fell to 27 acres and the house, described in 1816 as being commodious yet having no regularity of architectural character and in 1822 as an elegant seat, three-storeyed. It continued as a gentlemans residence under Mrs. Howard (1850-3), Henry Vallence (1853-6), Mrs. Geach (1856-61), John Coverdale (1862-7), and Thomas Brandon (1867-76), and in 1877 was offered for sale with 52 acres. After remaining empty it was leased as a school, to Margaret Clark (1882-98) and Lucy Soulsby (1898-1915). In 1891 the school added a classroom and dormitory block on the east and later a chapel beyond that. The house continued as a school until 1934 when, described as shabby-looking, it was bought by C. W. B. Simmonds, a builder, and was pulled down to make way for Manor Drive.
