The house and gardens are all that remain of an estate that once encompassed more than 590 hectares (1,500 acres).

[1] Since 1949 it has belonged to the War Office (now the Ministry of Defence),[1] and currently hosts an Army Cadet training centre.

[2] The estate of Frimley Manor was sold by Sir Henry Tichborne to James Lawrell the elder for £20,000 in 1789.

The house with 56 hectares (140 acres) of land was purchased by the Whig politician William Crompton-Stansfield in 1862.

In 1947 (shortly after the end of World War II) more land was sold separately and the remaining 12 hectares (30 acres) was purchased by the Officers' Association who two years later (in 1949) sold what remained of the estate to the current owners, the War Department (now the Ministry of Defence).
