An exemplar design for a CAT A to D, 800 to 1000 prisoner replacement scheme focused upon creating an operationally efficient design that optimises the service delivery, replacing the existing outdated facilities on a highly sensitive rural coastal site while maintaining the existing CNA throughout the works. The new facility and in particular the new therapeutic housing blocks was designed with the objective of delivering a range of fit for purpose, flexible, accommodation which promotes staff and prisoner safety, encourages access to education and activities and encourages and supports the rehabilitation of prisoners. Included in the design was a therapeutic space, areas conducive to rehabilitation, space for encouraging working out and Stepdown/independent living accommodation to prepare prisoners returning to society.
