149 Mwrog Street

Probably dating from the mid-19th century, 147 and 149 Mwrog Street form a pair of semi-detached houses. The porches and gabled dormers appear to be later 19th-century additions. The house to the left (number 147) has one window, while the house to the right (number 149) has two.

The houses are built as a tall, asymmetrical three-window block of two-and-a-half storeys. They are constructed of random stone, with a roughcast finish to the front, under a slate roof with wide boarded eaves. Brick stacks are located to the right end and to the left of the centre. Each house has an open-fronted gabled porch with a slate roof, tile cresting, a scrolled finial, and wave-moulded barge boards. The sides of the porches are rendered and feature four-pane wooden windows. The front elevation has three windows spaced unevenly on each storey. The ground and first floors have 16-pane hornless sash windows with flat heads and stone sills. The attic storey has gabled half-dormers containing tall, two-light wooden casements with horizontal glazing bars and top-hung lights; the gables are timber-framed with moulded barge boards. The west gable end is of random stone, while the east gable end abuts a lower terrace. The east gable is patched with brick and features an external brick stack, probably associated with the terrace. The rear elevation, partly visible, has a wide gabled wing in the centre, with three late 20th-century windows on the first floor, and an offset end stack.

The porch of number 149 is slightly offset to the left of the centre, and features a half-glazed panelled door.
