Cloister Hall

Cloister Hall is a Grade I listed two-storey house, featuring three windows and constructed from roughcast rubble stone. It has a slate eaves roof and stone end stacks. The windows are 12-pane sashes, and the central entrance consists of a six-panel door with four fielded panels. A double flight of steps leading up to the front door has been rebuilt since 1981. In front of the house, there is a low rubble garden wall that rises to the centre, flanked by ashlar piers at the steps. To the right, a similar pier continues as a retaining wall at the northeast corner of an outbuilding. There is a basement entrance to the undercrofts at the south end, accessed by stone steps.

The outbuilding to the north is two-storey on the north side and west end, and one storey on the south and east, built over vaults. It is made of rubble stone with a slate roof and features a high rubble stone stack on the east. At the northeast angle, there is a small projecting structure that incorporates a gargoyle. The north side has a door leading to the vault and a window above it. The west front has a window above and a large flight of outside steps providing access to a footpath between the building and the house. There is a cartshed located beneath the footpath. The lower part of the outbuilding has not been inspected, but it is possibly vaulted.

Attached to the northwest angle of the outbuilding is a large stone Tudor-arched gateway leading to the yard, likely dating from the early 19th century. This gateway has an inner rebate for doors and is situated on the site of a College gateway marked on a 1720 map. It features an inner segmental arch. Beyond the gateway, there is a thinner and lower wall leading to the riverbank at Cloister Bridge.

Behind the house, there are extensive remains of undercrofts associated with the crosswing, west wing, and service wing of the college. The high rubble stone walls support a grassed terrace, with vaulted undercrofts beneath the crosswing and outside steps leading up. The undercrofts of the west wing and the range extending towards the river are not accessible. The site is also designated as a Scheduled Ancient Monument (Pe 445) due to the undercrofts.
