Description
St. Loy is a house dating from the late 17th century, which was refronted in the 18th century and extended. It has a timber frame with a whitewashed brick front and a tiled roof. The building consists of three bays and was originally designed with a lobby entry. It is two storeys high, featuring a central entrance that is sheltered by a later gabled timber and tiled porch. On either side of the entrance are 12-pane horizontal sliding sash windows with hoods. The first floor has a central blind window with a fire insurance marker, flanked by 8-pane horizontal sliding sash windows. The eaves are close, and external gable end stacks have been added. The house has been extended to the right and to the rear. The interior has not been inspected.
