Repairs were made to the hall in the 1950s, and it was listed as a Grade II* structure on 25 February 1952. Its former stable block, to the west of the hall, was Grade II listed in 1974. The roof of the hall and an upper floor were severely damaged by a fire that started at around 3:30 am on 15 March 2016; the clock tower was also damaged. On 23 March, Jeremy Taylor from Cheadle Hulme was charged with arson in connection with the fire. In August 2017, after changing his plea and admitting guilt, he was sentenced to four and a half years in prison. The hall was added to the Heritage at Risk Register in October 2016. A planning application to restore the building was submitted in November 2016, with the intention of keeping as much of the original material as possible; , the building was scaffolded and undergoing repairs under a protective roof. The hall was partially rebuilt between 1795 and 1800 by Lewis Wyatt. It was altered around 1840 possibly by Edward Blore. Additions included a walled garden, an ice house, and glass houses. In the Victorian era the dining room was refurbished and a tenant's hall was added. The timber-framed manor house has a hall with two projecting wings, and a porch and dais bays. The entrance hall (also known as the ante-room) is thought to have previously been a chapel, which was subsequently turned into a billiards room, before becoming an entrance hall in the 1870s. In 1930, the hall was turned into a museum and art gallery. Most of the hall's original furniture was removed by the Tatton family in 1926 when they moved out, and most of the furniture and paintings displayed in the hall during its time as a museum were from the Manchester City Galleries collection. Until 2007 a re-enactment of the 1643 siege of Wythenshawe Hall by Cromwell's troops was staged every July. By 2004 the hall was only open once a week for four months in the year and in 2010 closed completely as a result of council spending cuts. One proposition was that Manchester City Council could sell the building to the National Trust. In summer 2012 the hall re-opened for 10 days for the Wythenshawe Games. A friends group was established in September 2012 to hold monthly open days and regular events at the hall. Furniture installed by the friends group (including a four-poster bed engraved with the Tatton family crest) was not damaged by the fire.
