Pen-y-Groes

Single-storey house of whitened rubble on boulder foundations, with old slate roof of heavy, graded small slates; tiled ridge, crude gable parapets and tiny loft lights. Squat end chimneys with weather-coursing and capping. Deeply-recessed entrance with old boarded door to L of centre, with small 4-pane late C19 window to the L, in original opening. To the R of the entrance is a further, lower entrance with window to the R, as before. Adjoining to the R gable end is a lower C19 lean-to with rectangular 6-pane sash to the front. A modern slate plaque records the birthplace of Richard Owen.
