Between 1872 and 1884, The Most Honorable John Henry Wellington Graham Loftus, 4th Marquess of Ely (1849-1889), under the guidance of his mother Lady Jane Hope Vere Loftus (Lady in Waiting to Queen Victoria), undertook an extensive rebuilding of the entire mansion, adding many of the famous elements such as the grand staircase, mosaic tiled floor, elaborate parquet flooring and technical elements which had not been seen in houses in Ireland at the time, such as flushing toilets and blown air heating. A lot of Lord Ely's inspiration was taken from Osborne House, the Queen's summer residence on the Isle of Wight. The extensive works were believed to have been undertaken to facilitate a visit from the Queen, but this didn't happen and the family never got to fully enjoy the house, with the 4th Marquess dying very young without issue and leaving the estate, in a poor financial state, to his cousin who eventually elected to place it on the market. A three-storey non-basement mansion, nine bays to the front with a balustraded parapet. In 1917, Loftus Hall was bought by the Sisters of Providence and turned into a convent and a school for young girls interested in joining the order. In 1983, it was purchased by Michael Devereaux who reopened it as "Loftus Hall Hotel", which was subsequently closed again in the late 1990s.
