Williams plan of the Abbey ruins of 1888, not marked on the 1843 Tithe map. Built of random rubble stone with a Victorian 'A' framed slate roof. Steps leading to loft doors on the east and west gable ends, whilst south elevation ground floor has three cart openings, three windows and two doors all with yellow stone voussoirs. The south elevation first floor has three loft windows which sit directly under the eaves, then outside stone steps which raise up to a loft door. North elevation has a central boarded door, and two sixteen pane loft windows towards the west end and four sixteen pane windows to the east end.
