The residential tower in the north-east corner was entered by a forebuilding, unusual in this region, 17 feet 6 inches by 7 feet 10 inches (5.33 by 2.39 m) in size and protected by a portcullis. Four storeys tall, each floor of the tower was reached by a spiral staircase and comprised two rooms, one large and one small chamber. The tower is built from sandstone; the forebuilding and uppermost floor are made of a lighter sandstone than the lower floors and may have been added retrospectively. The ground floor is and originally had a vaulted ceiling. The upper floors were well-lit with large, transomed windows, complete with window seats; the first and second floors were probably used by the Manners family and had large fireplaces, with the third floor used by the castle staff. The tower was possibly linked to a neighbouring hall complex by a doorway on the first floor, although any such complex has since been lost.
