Sir George Gilbert Scott’s circular to his father’s friends produced other work than workhouses including a delightful castle-like addition to Buckingham Gaol in 1839 for his father’s friend Thomas Barlett (c. 1795-1850), who was then mayor of Buckingham. It was semi-circular in plan in the style of the original mock castle of 1748, at a cost of £1,267. A gaolers house was added on the south side and the builder was John Moles.
