Some of the old walls of the manor were preserved and encased in the new work, including the north and south walls of the dining room, and the walls between the hall and gallery. When the walls of the old tower were broken to form the door between the hall and gallery, a silver coin "of considerable antiquity" was discovered. The construction was still unfinished by the death of the second earl in 1850, after which the family consulted architect Philip Charles Hardwick, who "with much talent and judgment completed the south and west fronts, after his own designs, following the general plan as intended by the late Earl," his widow wrote.
