house had been converted into a single tripartite room to form a picture gallery by Thomas Harrison. Further work was carried out in the room following this; Peter Cannon Brookes, the author of the 1991 guide to the house, concludes that the final appearance of the room "dates almost entirely from 1840–45". After Sir John's death the house was structurally reorganised for George Warren, 2nd Baron de Tabley by Robert Curzon, a family friend and an "amateur architect". The house was re-orientated to move the front entrance to the north side of the house. The architecture of the north front had previously been "simple and dignified", but it was enhanced to make its appearance more impressive. The alterations included adding rustication to the bottom storey and around the central window, and quoins to the three projecting central bays. The arms of the 2nd baron were added to the previously blank pediment, and in 1915 a small porch was built over the new entrance. The south portico had become redundant, other than serving as an entrance to the garden. The new entrance led by way of a small lobby to a new staircase up to a new entrance hall on the first floor. A new dining room was created in the northeast corner. The house and estate continued to be owned by the Leicester family until the death of Lt. Col. John Byrne Leicester Warren in 1975. The first request in his will was that the estate should if possible be taken into the care of the National Trust, but this was declined by the Trust. The executors then acted on Warren's second request, to pass the estate to a charitable institution, and thus it came into the care of the Victoria University of Manchester. By the time of Warren's death the manor of Nether Tabley, comprising the estate and the halls, had been owned by the Byrne-Leicester family for almost exactly 700 years. Col. Leicester-Warren used the house as a school from the late 1940s until 1984, after his death. In 1988 a 125-year lease of the house, the stables, and the associated buildings was sold by the university to Cygnet Health Care, on condition that the suite of rooms on the first floor of the house, and their contents, should be preserved. Between 1988 and 1990 the health care company carried out structural repairs to deal with damage caused
