Substantial alterations appear to have taken place during the early years of Samuel Egerton's ownership in the mid-18th century. The canopy at the dais end of the Great Hall was destroyed – although part of it can still be seen in the north wall – when a floor was inserted and new rooms were formed with lath and plaster partitions. The east wing of the hall was probably demolished at about the same time, but certainly before 1812, the date of the earliest estate map.
