Description

10 and 11 Sun Street is a late 17th century red brick building with two storeys. It features deep eaves under a steep tiled roof, which is adorned with three equally sized dormers that have two- or three-light leaded casements and unique triangular leaded lights on each side. At the northern end, there is a carriageway beneath a four-centred arch made of lighter red brick. The ground floor has a continuous modern shop window, while the upper floor contains nine windows. These windows are mullioned and transomed in wood with leaded casements in No 10, but No 11 has some sashed casements. Nos 4 to 11 form a group.
