Only the gatehouse and the west tower still survive, partially intact. The gatehouse was originally protected by a drawbridge and a portcullis. The gatehouse was rectangular, built from brick with stone detailing, with four polygonal turrets. Had it been completed, it might have been tall and have resembled the gatehouse at Layer Marney Tower. On the ground floor, two chambers, including the porter's lodge, flanked the gate passage. The first floor housed the portcullis mechanism and a garderobe. If the second floor was ever completed, it has since been lost. The west tower is across externally and internally, made of simple patterned brickwork, with three floors and two, slightly taller, turrets on the inside corners. Each floor had a single chamber, with a fireplace and an adjacent garderobe, which would have formed lodgings for senior members of the household.
