In 1739 the Dean and Chapter bought back the property from the Crown for £500, and it reverted to the use of the prior's direct equivalent, the sub-dean. The house was the object of a scandalous legal and parliamentary battle between the
canons of Westminster Abbey and
Westminster School for twenty years after the
Clarendon Commission recommended that
Westminster Abbey surrender it to the school upon the demise of its current occupant, the redoubtable sub-dean the Reverend
Lord John Thynne, who lived there with his equally formidable wife and nine children. The Dean and Chapter attempted to evade their obligations under the
Public Schools Act, by purportedly using their control of the school's governing body to sell out the school's statutory right for the benefit of the Canons. Even after this was defeated by a debate in Parliament, Lord John survived until 1881, once surprising the headmaster who was looking over his garden wall from a ladder, by leaning out of a window with the words "Not dead yet, Dr. Gow!" The house was the original location of Westminster's first day-
house, also known as Ashburnham House, from when it was founded until it moved in 1951 to 6
Dean's Yard. The day-boys continued to lunch there until the 1970s, and the mediaeval ground floor is now primarily used for catering and social functions, while the seventeenth-century first floor drawing rooms, now extending right through into the former John Sergeant ante-room to School, form a superb library suite. == Second World War ==
