B. Lewis of the University of Melbourne. All prisoners were accommodated in single occupancy cells containing a toilet and hand basin with running water. Heating was also provided in the cells together with access to local radio stations on headphones. During construction, inmate populations increased, and Lewis's original plans were changed by adding 72 additional cells, halving the space devoted to exercise yards. None of the other prison facilities, such as workshops and recreation space, were enlarged to allow for the increased capacity. The complex houses maximum security inmates within its Derwent, Huon, Franklin and Tamar units. With the exception of Tamar, mainstream maximum-security units each have 26 beds, mostly single bed cells but with several two-bed 'buddy' cells. The cells are located over two storeys around a common 'day' area including lounge and dining facilities. Cells are equipped with a shower, toilet, bed, writing desk and television. Access is available to an attached, mesh-enclosed, exercise yard. The maximum-security part of the campus also includes needs assessment, protection, crisis support, detention and behaviour management units, with layouts similar to the mainstream units. The behaviour management unit, called Tamar, is an 8-cell high security unit used to house prisoners who are considered to pose a particularly high risk to correctional staff, to other prisoners or detainees, or to the maintenance of good order and security in the prison. Wilfred Lopes Centre for Forensic Mental Health In 2006, the Wilfred Lopes Centre for Forensic Mental Health replaced the Risdon Prison Hospital. The prison hospital was located within the grounds of the old H.M. Risdon Prison and had 28 single cells that provided medical assessment on reception, outpatient care, inpatient care, and inpatient psychiatric care. The Wilfred Lopes Centre is situated near the Risdon Prison Complex, but is not part of the prison. It is a health facility owned and managed by the Department of Health and Human Services. Patients are provided with modern, professional and highly specialised psychiatric care and treatment. Treatment is based on individually tailored programs designed to support independence and dignity, and minimise the ill effects of long-term care. The 35-bed unit caters for the varying needs of clients, including a mix of males and females. The grounds are landscaped to help create a therapeutic environment. The Centre includes 12 beds in a High Dependency Unit, for people with acute illness; 18 beds in an Extended Care Unit, for
