Description
3 Arthog Terrace is a long-planned terrace of 12 gabled houses built in the third quarter of the 19th century. The building features two storeys constructed of rubble with a continuous slate roof, boarded eaves, and brick chimneys that have a toothed neck-band. The houses are arranged in six reflected pairs, each with central entrances that have boarded doors. These entrances are flanked by original small-pane sash windows, with 12-pane windows on the outer sides and 16-pane windows on the inner sides of each pair. The first floor has 12-pane windows, each topped with gables that have moulded bargeboards and central arrow-finials. A continuous string course runs above the voussoir lintels on the ground floor. Number 6 has later boarded double doors, while numbers 10 and 11 feature 20th-century open and trellised gabled porches, respectively. Number 12, located at the far right, has a wider but still contemporary 12-pane window.
