Description from record TQ 45 SW 35 :
[TQ 4460 5389] Squerryes Lodge (NAT) (2) Squerries Lodge, originally the Dower house to Squerries Court [TQ 45 SW 34] 18 c. rendered elevations of 2 storeys. Hip tile roof and dormers. N. elevation is mostly modern. Whole structure thoroughly repaired as result of bomb damage. W. and S. elevations are 18c. of varying dates. The building incorporates portions of a 12 c. structure, which was some kind of monastic establishment. There are bricked-up Norman arches with walls about 3 feet thick forming part of the kitchen wing. Also remains of a chapel now used as store room. (3) c. 1327, Hamo, Bishop of Rochester, endowed a perpetual vicarage in Westerham church, and decreed that a competant house be built. The rectory and advowson remained with the prior and convent of Christ Church, Canterbury until the Suppression. (4) Squerryes Lodge, as described by the Min. of Housing, except that the E. wing incorporates the remains of a 14th c. building as evidenced by the roofing trusses and a number of blocked windows (see GP/AO/62/296/2). This building, the upper part of which is said to have been a chapel and to contain a 'priests hole', was probably the old parsonage described by Hasted but the owner of Squerryes Lodge could offer no further information.
