19 Heol Pentrehedyn

19 Heol Pentrehedyn is a late Georgian building dating from around 1800. It is a two-storey structure with two-window fronts. Numbers 17 and 19 are reflected pairs and are rendered, while number 15 is pebbledashed. The building features ornamental cement quoins at the ends and to the right of number 15. It has a steep hipped slate roof, which is grouted to numbers 17, with wide boarded eaves and large rubble chimney stacks.

The sash windows at numbers 17 and 19 have architraves, with the 12-pane glazing retained only on the first floor of number 17; the other windows are mostly horned and have 4-pane glazing. Numbers 17 and 19 also feature simple classical doorcases with modern panelled doors flanked by pilasters, while number 15 has a recessed small pane door. Additionally, numbers 17 and 19 have cellar openings.

There are modern flat roof extensions at the rear and one older gabled cross range at number 17, which also has 12-pane sash windows at the rear.
