Description
These are two 17th-century cottages, originally with gable ends facing the street, and later refaced. Number 11 is two storeys high, while number 12 is three storeys high, each with a single window. They are rendered with cement. Both have sash windows with flush boxes set within flat arches; the glazing bars are largely intact, except for a small two-light casement window in the attic storey of number 12. Each doorway has a small, plain flat hood above it, with the hood on number 12 supported by brackets. The entrance to number 12 is recessed within the reveals, and it features a six-panelled door with the top two panels cut away and glazed.
