Description
9A Heol Tan-y-bryn is part of a row of four houses numbered 7A to 10A in Abergynolwyn. These houses were built from slate rubble and feature slate roofs. They are two storeys high, with attics and cellars, and have a double-depth plan consisting of two and three bays. The doors have three raised-moulded panels and are set in staff-moulded frames with deep fanlights above. The ground and first floors have twelve-paned sash windows, while the rear attic features six-pane windows. All openings are topped with deep stone lintels, and the chimney stacks with outsetting heads are located on the party walls.
Number 9A has two window bays and is wider than the adjacent No 8A. It features a three-panelled door and twelve-pane horned sash windows. There are railings and a gate at the front. The original rear service building has been extended in line with the main structure.
