The house passed to William Pynsent, who married Mary Star, the widowed daughter of Thomas Jennings.

[2] His intention was to disinherit Lord North, a relative of his wife,[3] who had supported a tax on Somerset cider which Pynsent disagreed with,[4] and which Pitt had blocked.

[4] Pitt immediately commissioned Lancelot Brown to design a monument in memory of Pynsent's generosity, built by Philip Pear at a cost of £2,000 (equivalent to £345,309 in 2023).

Brown also advised on the landscaping of the parkland and possibly designed the wing that Pitt built on the eastern end of the house.

[7] Pitt sold part of the estate to help repurchase his seat at Hayes Place, Kent, but still resided at Burton Pynsent for periods until his death in 1778.

The estate was split up and sold in 1805,[4] to pay for John Pitt's gambling debts,[8] with the house and park being purchased for £8,810 (equivalent to £903,025 in 2023).

[4] The grounds were laid out in the mid 18th century by Pitt and Lancelot Brown; and they include early-20th-century formal gardens designed by Peto.

The two-storey building is constructed of brick in a classical style, dressed with ham stone features and a hipped tile roof.

[4] In 2001 the house was put up for rent for £36,000 (equivalent to £75,203 in 2023), described as having seven bedrooms, four bathrooms and half a dozen reception rooms and offices.

[4] The entrance to Burton Pynsent House is between a pair of 18th-century square brick columns, decorated with ham stone, flanked by walls.
