Description

Priory House is a two-storey house with attics and cellars, constructed from local rubble masonry, with the rear elevation being roughcast rendered. The roof is covered with small slates and features stone copings on the gable parapet to the south, topped with a ball finial. The main elevation faces east into the cloister court and has a three-window range of small-paned casement windows with timber lintels, and a doorway that is offset to the right. To the right of the doorway, steps lead down to a cellar doorway that has a large stone lintel. The rear elevation is marked by a pair of large projecting stacks, with casement windows in between, including a raking dormer and a raking half dormer that disrupts the eaves line.

The layout of the house dates from an early 20th-century re-ordering, featuring a central corridor plan with a Jacobethan staircase at the rear and principal rooms on either side. The central passage includes some refixed panelling from the early 17th century, which has scratched-mouldings and a modern cornice; this panelling originally formed a partition on the first floor. The parlour is adorned with oak panelling from the early 18th century, complete with a moulded cornice and dado. On the first floor, there is a fireplace that may date back to the 16th century, featuring stone chamfered jambs with broach-stops and a stone lintel supported by ogee-shaped corbels, though it has later brick filling and a re-dressed grate and stonework.
