Description
Heol Pentrehedyn is a late Georgian building from around 1800, featuring two storeys and two-window fronts. Numbers 17 and 19 are reflected pairs with a rendered finish, while Number 15 is pebbledashed. The building has ornamental cement quoins at the ends and to the right of Number 15. It is topped with a steep hipped slate roof, grouted to Numbers 17, and has wide boarded eaves along with large rubble chimney stacks.
The sash windows at Numbers 17 and 19 have architraves, with 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 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.
At the rear, there are modern flat roof extensions and one older gabled cross range attached to Number 17, which also has 12-pane sash windows on its rear side.
