"Licence, with the assent of the lords spiritual and temporal and of the commonalty of the realm of England in the present Parliament, for Humphrey, duke of Gloucester, and Eleanor, his wife, to impark 200 acres of land, pasture, wood, heath and furze at Grenewyche, outside the metes of the forest ; notwithstanding that 40 acres of pasture, heath and furze out of the said 200 acres are parcel of the manor of Grenewych granted to the prior and convent of the house of Jesus of Bethlehem of Shene by its founder, Henry V, and now granted by the said prior and convent to the said duke and duchess in exchange for other lands. Licence also for the said duke and duchess to crenellate their manor- house or mansion of Grenewych, and to build and crenellate a tower within the said park. By pet. in Parl."
Granted at Westminster, by privy seal.
This has very similar wording to a licence granted in 1433 for 'Estgrenewich'. This is clearly a repeat of the licence to impark and, presumably, for the building work. Coulson (1995) list this as a, suburban town house. I consider it a ordinary country manor close to London.
