Gateway, Attached Garden Walls and Coach House to South of Main Front of Chastleton House

The gateway, attached garden walls, and coach house located to the south of the main front of Chastleton House are likely from the early 17th century, with some minor later alterations. The gateway is made of limestone ashlar and features a chamfered round-headed archway with a hoodmould and plain imposts. It is topped with a moulded pediment that has finials at the corners and center, and there is a coat-of-arms with a lion rampant on the rear side.

The garden wall is constructed from regularly coursed and dressed marlstone, with ashlar coping at the front and rounded rubble coping with a dripmould on the sides, ramping at the corners. It encloses a rectangular area measuring approximately 50 meters by 25 meters, as well as a stable yard to the southwest. The northeast side has a chamfered Tudor arch with a plank door at the angle with the north churchyard wall, and a similar doorway with an iron gate a few meters south where it connects to Chastleton House.

The southwest side includes a small coach house facing the stable yard, built from regularly coursed marlstone rubble with coped verges, carved apexes, and stepped ashlar decoration on the gable ends. The roofing material was removed at the time of the resurvey in August 1987. The coach house has a 2-bay front with two sets of wide plank double doors separated by a stone column. It is linked to the stables by a short section of ashlar wall featuring a moulded 4-centred arch, which continues north for a few meters to join Chastleton House. Inside the coach house, there is an inserted loft, with only the tie beam and the bottom of the principal rafters of the 2-bay roof structure visible at the time of the resurvey.
