St. Thomas' House, including attached railings

St. Thomas’ House is a probably mid-Georgian building, likely dating from the mid-18th century, constructed with a smooth stucco facade over local rubble, and covered by a Welsh slate roof. It is a three-storey building with a double-depth central entrance plan, originally featuring three windows. The front door is a six-panel door with a transom light, later fitted with a flat hood supported by brackets. Ground floor windows are nine-over-nine sash windows, with small half-panes on either side. First-floor level features canted oriel windows on brackets, each with a central nine-over-nine sash window and two-over-two sashes on the sides, all with slate roofs. The upper floor windows are four-over-eight pane sashes flanking a three-over-six sash. The roof has a low pitch, with a brick stack on each gable. Attached to the front are wrought iron railings and a gate enclosing the front garden. The rear elevation has been altered.

The interior is plain and was altered in the later 19th century, with joinery mostly dating from that period.
