Ty Hen (including garage room to Penygroes)

Ty Hen is a two-storey cottage dating from the 18th century, constructed of slate-rubble with a double-pitch Welsh slate roof that has projecting eaves and timber fascias. The cottage is situated on Dinas Road, where the north gable frontage is canted and features a single-storey lean-to extension to the left side, built in the same material. A later extension to the south, now used as storage space, is also present.

The front door is located in the right corner of the gable, alongside a 16-pane recessed hornless sash window. A 9-pane hornless sash window sits above the door, with a rendered section filling the space between. The gable is otherwise blank except for a single-pane modern window in the lean-to extension. A rendered area below this window indicates a previously infilled doorway. The east-facing left elevation has three early recessed hornless sash windows on the upper floor: a central 9-pane window, and 16-pane windows on either side. Slate sills are present. A rendered lean-to spans the ground floor, with a recent slate roof and lead flashings, incorporating two modern rooflights. To the left of the main range on this side is a double door with a massive slate stone lintel, originally a workshop, and now serving as a garage for the neighbouring property. The west-facing elevation is largely hidden by adjacent buildings, with a single modern rooflight visible towards the rear.

The cottage has a single-room plan with added lean-to elements, incorporating a flying freehold which increases the first floor area. Entry is from Dinas Road into a small timber-framed vestibule in the corner of the living room. A timber staircase leads to the upper level, and there is a step down into a lean-to kitchen, both aligned along the rear wall. A separate ground floor room, used as a garage by the neighbouring property, was not inspected. The upper floor includes a small landing. A bathroom window is situated over the front door, overlooking the entrance. A front bedroom has two windows and a modern internal window overlooking the staircase. A second bedroom, a "flying freehold" over the neighbour’s garage room, is accessible via a door on the left side of the landing.

The living room features a slate flag floor, early pantry cupboard doors, a fireplace stove with a slate hearth and a narrow staircase characterised by thin square cut balusters and a turned vasiform newel post. The lean-to kitchen has been modernised, retaining a recessed area in the wall believed to be the location of an infilled doorway leading to the east side of the building. A single exposed timber roofbeam and a large trapezoidal slate windowsill are visible in the "flying" bedroom. Secondary glazing has been added to the sash windows. The garage room, located beneath the "flying" bedroom, features slate flags near the entrance.
