25, Castle Street

No. 25 Castle Street is a shop that was formerly a house and business premises, dating from the 17th century or possibly earlier. It was remodeled in the early or mid-19th century and re-fronted in the late 19th century. The building is constructed of plastered stone rubble, with some brick alterations, including timber-bonded sections. The added front is made of red brick in English garden-wall bond, featuring stone dressings. The roof of the front range is slated, while the remainder is covered with corrugated iron.

The front range has a brick chimney on the right-hand gable and the base of another on the left-hand gable. There is a large stone chimney on the rear gable of the rear wing, topped with an added brick shaft. A stone stack is located at the left-hand end of the rear verge, now only visible in the roof space. The building's plan consists of a range parallel to the street, with a rear wing at a right angle on the left side, abutting a rear range that is also parallel to the street, forming a courtyard with buildings on three sides. The front range has been cut through the ground story on the right-hand side, likely during the 19th century.

The building is two storeys tall. The front features a shop window in the center of the ground storey, with a doorway to the left and a carriage entrance to the right. The upper storey has a canted bay window with a moulded base on the left and a pair of sash windows on the right. There is a bracketed eaves cornice. The courtyard contains 19th-century sashes and wood casements, most of which have glazing bars, along with an 8-paned sash under the rear carriage arch.

The interior has only been partly inspected but appears to have been significantly remodeled in the 19th century. However, there are likely early fireplaces, beams, and other features concealed under plaster. The roof spaces are not accessible, except for the rear range, which has heavy timbers from the 17th century or earlier. The truss at the left-hand end likely has a halved collar with plain ends set into the principals, along with threaded purlins and a ridge. Town houses with this type of courtyard plan are rare in Devon.
