An open prison in Derbyshire has been praised in an official report, but told to improve some of its facilities.
Anne Owers, Chief Inspector of Prisons, said Sudbury provides a safe and well-ordered environment.
She said it encourages inmates to find work but the buildings cannot cope with the growing number of disabled and older prisoners.
Governor Chris Davidson said: "We are gradually improving the site, making better access to buildings.
"We have installed a ramp to the dining hall, we have moved the library into a new venue and we have had it road-tested by a prisoner in a wheelchair which has helped us with the layout of the shelves in there."
