Description
Grawen is a two-storey building constructed from partly coursed rubble with ashlar dressings and a projecting hipped slate roof. It features rectangular dripmoulds above plain window openings, which have modern glazing. There is a blind window above a modern door, also with a dripmould. The building has a plinth and short screen walls on both the left and right sides. At the rear, there is a three-storey section due to a steep drop in the ground.
