The hospital also offers drug and alcohol rehabilitation inpatient services,[2] and is the base for a number of community mental health teams.

[3] Opened as a prison in 1779, many of its buildings and the co-located Glenside campus of the University of the West of England (UWE) are Grade II listed.

In 2009, 21 acres (8.5 ha) of the site, incorporating the oldest buildings, was sold to the UK Government's Homes and Communities Agency, for redevelopment as part of a wider regeneration project.

[7] At the start of the First World War, the site was turned over to become Stapleton Institution for the Maintenance and Workshop Training of Certified Mental Defectives.

Even after takeover, the previous regime stayed in place, with patients assessed as capable enough working for their keep in the hospital's kitchens, bakery and for local farms.

[4] The hospital was staffed by eight consultancy teams, and much of its workhouse-related architecture was removed, reducing ward sizes, and replacing farming and work areas with gardens.

[12] A charity for research into Alzheimer's disease, BRACE, and the Regional Quality Control Laboratories continued to use the site under a lease from NBT until July 2010.

In 2007, they declared the Blackberry Hill site surplus to requirements, while AWP moved some of its older people services to Callington Road and Southmead hospitals.

[15] In 2009, the residual 21 acres (8.5 ha) Blackberry Hill site was sold to the UK Government's Homes and Communities Agency to be redeveloped as part of a wider regeneration project.

The buildings which are mainly Grade II listed will be converted into a mixed-use development of flats, houses, shops and small business premises.
