Description from record TQ 83 SE 26:
A four-bay medieval hall, very heavily modernised. Reputedly a gatehouse of the old manor house but there is no documentary evidence to prove this

In 1487 John Guldeford was granted a licence to crenellate his manor or tenement in Tenterden. The Guldeford family is associated by Hasted with Pitlesden [sic] so that the association goes back to at least the late 18th century. It would appear probable that Pitlesden was the site granted a licence; such a grant would not necessarily indicate that a building programme was carried out, or that any subsequent building was fortified, or constructed of materials appropriate to a fortified building (i.e. of stone). (2)

Described as a small "half-timbered, hipped-roof" house, with no overhang. The external timbers are said to be "widely-spaced", suggesting a 14th-century date. Interior arrangement as described in (1) noted. Reference given to a Mr E W Parkin who "calls it the sole survivor of three such gatehouses to a long-lost 14th century mansion". (2)
