The area where the house stood still retains the Haydon Hall name, and includes a cricket club and public meeting rooms.
Sitwell was an ironmaster, although his ironworks failed and he was lent money by his father-in-law, Ralph Hawtrey, with Haydon Hall as security.
[2] Under the later ownership of the Scropes family from Cockerington, the house was renamed "Eastcote Park" from 1770 until 1789 when it returned to the original Haydon Hall name.
It was expanded in March 1827 to include a Sunday school, continuing after Dr Clarke's death in 1832 until his daughter-in-law's husband, John Harnett, forced the Methodists to leave the cottage.
[3] Lawrence James Baker of the London Stock Exchange bought the house and grounds in 1864 and had two additional wings added.
Baker had several new cottages built for workers within the grounds, designed by Harold Peto of Eastcote House and Ernest George.
He bought the land in 1873, eventually owning 387 acres (157 ha), and had gamekeeper's cottages built in Fore Street and Mad Bess Woods.
