The estate was purchased in 1711 by Robert Raymond, then Solicitor General and later Attorney General, subsequently Baron Raymond, who was Lord Chief Justice of England and Wales from 1724 until 1732.
In 1720 he demolished the original house, of which little is known, and built a mansion which still stands on the site today. A park was laid out around the house in the later eighteenth century. His cipher, a griffin in a crown, can still be seen on the building.
On the death of his son, Robert Raymond, 2nd Baron Raymond, without issue in 1756, the manor was left to Sir Beversham Filmer, 5th Baronet, of East Sutton, Kent. He, dying unmarried in 1763, bequeathed it to his nephew, Sir John Filmer (7th Bt). It then descended in the family till 1838. The Filmers were absentee landlords.
Fearnley Whittingstall 1838–1856
In 1838 Sir Edmund Filmer (8th Bt) sold the estate to Edmund Fearnley Whittingstall (né Fearnley), a Watford brewer. He started a bank in partnership with William Smith which went into bankruptcy soon after Whittingstall's death, forcing the sale of the estate in 1856.
Jones Loyd 1856–1947
The estate was then held by William Jones Loyd (1821–1885), a partner in the London branch of Jones Loyd & Co, who was High Sheriff of Hertfordshire in 1861 and cousin to Samuel Jones-Loyd, 1st Baron Overstone. Jones Loyd built the nearby church of St Pauls in 1864.
In 1947 the estate was sold to Hertfordshire County Council who converted the house and grounds into a secondary school, named Langleybury School, which opened in 1949. In the late 1950s a modern school was built to the south of the mansion, which remained in use as part of the school and as teacher accommodation.
Langleybury School closed in 1996 and for a time partly housed Hertfordshire County Council Social Services offices. The empty modern school became a favoured film location site, notably for the Hope and Glory TV series of 1999.
It is also used as a CCB (close combat battle) area for people who play Airsoft (an outdoor combat game) in the buildings which are still safe to enter.
A children’s farm is situated in the old farm attached to the mansion house.

When he (George Whittingstall) died in 1822 he left £500,000 to a distant cousin Edmund Fearnley provided that he was prepared to change his name to Edmund Fearnley Whittingstall. This was legally recognised by 1825 and Edmund F.
