Description

Nos 9 and 11 on Old Quay Street are late 18th century to early 19th century cottages. They are constructed from granite rubble and feature a slurried slate roof, with one end hipped. The buildings are two storeys high and have four windows, which are small restored sashes without glazing bars. At the centre, there are two modern glazed doors with a passageway between them. These cottages are included for their group value, as they form a group with No 7.
