Watching brief of geotechnical test-pits did not distinguish whether the land was terraced into or built up for construction of house and gardens. Land bought by Baroness de Rothschild for her son and the house was built between 1851 and 1854. The house was built on made ground in order to take advantage of the views looking south to the Vale of Aylesbury and the Chiltern escarpment. The house, contents and grounds were eventually sold in 1977 (B4, B17).
