Before 1370 the manor passed on again by marriage to the Dabridgecourts,[2] and in 1629 they sold the property to the Pitt family, cousins of the great father-and-son Prime Ministers.

The main part of the house was extensively enlarged around 1630 by Sir William Pitt, Comptroller of the Household to King James I.

Sir William's eldest son, Edward Pitt (1592–1643), MP, of Steepleton Iwerne, Dorset, and later of Stratfield Saye, bought the estate for £4,800 in 1629.

These plans were abandoned in 1821, when they proved to be too expensive, and subsequently the duke made numerous additions and improvements to the existing building.

The Duke's cast bronze funeral carriage, made from melted-down French cannons captured at the Battle of Waterloo, was moved to Stratfield Saye in the 1980s.
