Description
No. 33 on St Thomas Street is a town house built in the late 18th century. It features granite rubble walls and a steep dry slate hipped roof with a modillion eaves cornice. The building has a double-depth plan and stands three storeys high with a symmetrical two-window front. The ground floor has been altered with rebuilt three-storey canted bays, which include 20th-century replica sash windows, and a central doorway that is pilastered with carved consoles and a moulded hood cornice.
Inside, an inspection around 1980 revealed an original open-well closed-string staircase with stick balusters and a ramped mahogany handrail, complete with turned newels, as well as some late 18th-century chimneypieces.
