Description
Nos 15 and 17 Sun Street are a pair of cottages, now functioning as a house, dating from the early 19th century. The buildings are timber-framed and weather-boarded, topped with a plain tiled roof. There is a stack on the left side and two flat-headed dormers. The structure has two storeys and attics, featuring a two-window front with sliding sashes, where the left window is slightly wider than the right. The entrance has a panelled door set within a pilastered surround, topped with a cornice that is off-centre to the left. These cottages are included in the listing for their group value.
