[1] In 1424 there was a substantial rebuilding of the castle by Richard de Beauchamp, the Earl of Warwick, with a hundred oak trees used to create a complex with a parlour, a solar and chambers.

[1] Edward North, a successful lawyer, rebuilt the castle in the 1540s and between 1556 and 1558 using the architect Francis Adams, renaming it Kirtling Hall.

[3] The castle continued to develop, and by the 1660s was the largest country house in Cambridgeshire, centered on a symmetrical two-storeyed south-facing range, with east and west wings providing additional accommodation and facilities.

[1] Much of the castle was pulled down in 1748 in order to make the remainder habitable for Lord Elibank, but the property went into decline again after his death in 1762.

[1] In the 1830s the gatehouse was turned into a residential property and was renamed Kirtling Tower; an extension was built in 1872 and the house remained in use under a sequence of tenants.
