In 1311 Sept 29, Hugo le Despenser, senior was granted, by Edward II, (In year 5 of his reign) a Royal licence to crenellate omnes domos et cameras in quibuscunque maneriis suis in regno nostro
Licence for Hugh le Despenser, the elder, to crenellate all his dwelling-houses and chambers in his manors throughout the realm. By K. (CPR)
Hugo le Despenser, senior ... omnes domos et cameras in quibuscunque maneriis suis in regno nostro. (Turner and Parker)
Granted at London. Grant by King.
Given his considerable holdings the cost of even modest rebuilding of ALL his holdings would have been prohibitive. It is likely this licence is entirely intended as a symbolic statement of royal favour rather than as any intent to build anything in particular.

(In fact, the original source given is usually a transcription/translation
of what are precious medieval documents not readily availably. It should be
noted that these transcription/translations often date to the nineteenth or
early twentieth centuries and that unwitting bias of transcribers may affect
the translation. Care should also be taken to avoid giving modern meaning to
the medieval use of certain stock words and terms. Licentia is best translated as 'freedom to' not 'permission'.)
