Description
20 Thames Street is an early 18th-century building constructed of brown brick with red dressings. It features a steeply gabled tiled roof that has two weather-boarded and gabled dormers. The façade includes two sash windows set in slightly protruding panels, positioned beneath a moulded eaves cornice and a brick band course below the cill level. On the ground floor, there are two 18th-century shop window bays, which are no longer in use, along with a recessed central glazed entrance doorway that has margins. This entrance is accessed by three steps with iron railings. A flat hood extends across the full width of the building, positioned at window level.
