 A new horseshoe-shaped extension was opened in 2003, but the old buildings - including the out-patients department - remained in use until October 2007.Most of the buildings are due to be retained owing to their historic importance, though some of the less significant structures are set to be demolished to make way for a housing development - these include the wards at the rear of the site which were built in the 1930s, as well as the hydrotherapy pool and physiotherapy department.The administration building, former out-patients unit and hospital lodge are set to be retained to form residential properties.
