In the mid-17th century, Richard Scott acquired the house then standing on the site and known as Nether House. In about 1777, Joseph Scott replaced the old house with a two-storey, nine-bay mansion in the Strawberry Hill GothicRevival style. The house was much altered and extended about 1840 and in 1863, an adjacent chapel was erected to a design probably of architect George Gilbert Scott, a friend – but not a relation – of Sir Francis Scott. Two of the extant lodge houses are believed to be by George Gilbert Scott. Outside the chapel are the burial plots of several of Lady Bateman Scott's pets, inscribed with poems she wrote for them. Financial problems led the Scott Family, to lease out the hall from about 1788 to Samuel Galton, and for some years the Hall became a venue for meetings of the Lunar Society. It is said to be the 'favourite place of meeting' of this illustrious body. In 1999, stone memorials to the Lunar Society, the "Moonstones", were erected at the nearby Asdasupermarket. In 1791, Sir Francis Scott, 3rd Baronet, inherited the manor of Great Barr from his maternal uncle Thomas Hoo and was able to return to live in the house on the expiry of the lease. He died in 1863. His widow Mildred lived on in the Hall until her death in 1909.
After the Scotts
In 1911, the estate was purchased by a local hospital board and, in 1918, became St Margaret's Mental Hospital. Many detached hospital buildings were erected near the hall, and in the 1980s the grounds became a nature reserve, managed by the Staffordshire Nature Conservation Trust but the hall itself was abandoned in 1978 and, despite its 1971 Grade II* listing, was left to decay. The hospital began to close in phases from the late 1980s. The male department closed during 1992 but the female department closed in March 1997. The final residents, those with high dependency, left a newer part of the site in 2004. This also included a special school, The Queslett School, which closed in December 1988. Many years passed during which discussions and negotiations for the protection of the hall came to nothing. In 2006, Bovis Homes purchased the 40 hectare estate and obtained planning permission for the redevelopment of the site. As of 2011, Nether Hall Park a new residential housing development, occupying a substantial part of the estate, is in course of completion. In May 2011 the hall, still in ruins, was put up for sale for £2.2 million, by the Manor Building Preservation Trust, who had been allowed to purchase it nine years earlier for £900,000. The trust had failed to bring it back into a safe state. It failed to sell, and so was offered for sale by auction on 6 February 2012, by Van Weenan Estate Agents of London, with a guide price of £1,250,000. The highest bid was £1,140,000, and so it again remained unsold. In May 2012, it was sold to a consortium of ten local residents. They have commissioned Lapworth Architects to consult with the public and investigate potential new uses for the hall. The hall is on English Heritage's "Buildings at Risk Register".

and three are lost:
