A 16th century building approximately 7 metres square located outside the Abbey building immediately to the south of the south aisle between the charnel chapel and a possible porch leading into the abbey from the lay cemetery. The purpose of the building is unclear. It may have been built some time after the Dissolution although this would mean that it would have had a life of only 15 years. The footings of the building are insubstantial and poorly made and this suggests that the building was a temporary construction possibly used as a workshop by the men engaged in dismantling the abbey.
