St John's Priory, Including the Ruins of the Priory

St John's Priory, including the ruins of the Priory, is a large L-shaped house with an early 18th-century front, possibly older behind the facade. The building has two storeys, attics, and a basement, constructed of red brick on a base of stone rubble with flint galleting. It features a tiled roof with two hipped dormers on the Ashford Road elevation and a parapet. There are seven sash windows facing High Street, three sash windows and two blank window spaces facing Ashford Road, with glazing bars intact except in three ground floor windows on the High Street front, which also have brick architraves above. The entrance is accessed by five steps and features a doorcase with a moulded architrave surround, a rectangular fanlight, a large flat hood on carved brackets, and a door with eight fielded panels. There are also two inserted bow windows. The side facing Ashford Road has a recessed doorcase with a rectangular fanlight above.

Inside, the building retains some panelling and a notable staircase with two turned balusters on each tread and scrolled tread ends. At the rear of the house are the ruins of a medieval Priory founded in the 13th century. The main part consists of a small two-storey building made of stone rubble with a tiled roof, featuring three windows—one small rectangular window and two windows with two lights each, which have corbel heads in the spandrel between the lights and a dripstone above. There is a pointed doorway that is now bricked up, with a similar corbel head above it, and another unblocked pointed doorway to the north without a corbel head. The interior has exposed beams. Behind this complete building to the north is a reconstructed wall made of medieval stones, which contains one small pointed window, two small rectangular windows, one blocked window with two quatrefoil-headed lights and a corbel bracket above, and a large depressed (almost square-headed) archway in the center (now bricked up) with the remains of a window above it and a corbel bracket.

St John's Priory, along with Nos 38, 40, 46, and 48, forms a group.
