 The skillion addition seems to have been an afterthought to accommodate the schoolmaster but seems to be almost contemporary with the main building as the brick work and fireplace are bonded into the main building.It has been claimed that it was built of sun-dried bricks with stone quoins and was whitewashed with lime to which fat had been added to protect it from the weather.However, in the absence of documentary proof or physical analysis to confirm it this claim cannot be verified.
