Description
Trygarn is a building constructed from rubble stone with a slate roof and gable end chimneys. It features a symmetrical east front. Originally, there were five 16-pane sash windows on the upper storey, and on the ground floor, there were two 16-pane sashes on either side of a central doorway, which has a three-pane rectangular overlight. The roof has 20th-century dormers. The west elevation is noted for its unusual design, featuring a central door to the cellar, with windows at intermediate levels that light the first and second stair landings. There are four additional windows that provide light to the living rooms and bedrooms.
While the interior was not accessible during the resurvey, the description from the Royal Commission on the Ancient and Historical Monuments of Wales indicates that the ground floor is divided by a central stair. To the south is a small parlour that has contemporary panelling and a panelled door. Adjacent to it is a small room that lacks original features. To the north is the kitchen, where it is unclear if the wide, now-blocked fireplace is an original feature or a later addition. The west window contains a reset pane inscribed with "Robert Trygarn 1730." The stair, although repaired in some areas, is original and features a closed string with turned balusters and a moulded handrail. The risers are moulded in the same profile as the panel above the parlour door.
