Bryn Tirion

Two-storey house of whitened limestone rubble construction under a medium-pitched, renewed slate roof; 2-stage later C19 brick chimneys, one lateral and one to the L gable. Off-centre entrance (L) with segmental arch and rough-dressed voussoirs; C20 part-glazed door in a C19 pegged frame. Flanking windows on both floors, all with similar segmental arches. Those to the first floor are near-flush pegged wooden cross-windows with casements having small-pane glazing (perhaps originally leaded). The right-hand ground floor window is a large 3-light transmullioned window of similar type, with plain modern glazing. Squatter cross-window to the L of the entrance, with plain glazing as before. Modern window to the unwhitened R gable end with a cross-window with tilting upper casements above. Further modern window to the L gable end at ground floor level. The rear has a single-storey former dairy outshut (early C19, raised early C20) with modern window and a later lean-to porch extruded in the angle with the house; this with C20 part-glazed door and cross-window to the N. Immediately to the R of this is a blocked entrance.

Conventional sub-medieval plan-form with unheated parlour and service bay to the L and 3-bay hall to the R of the entrance. The latter has 2 large stopped and chamfered lateral beams, of which that closest to the entrance has a later partition below. The joists are plastered over, though are said to survive. Tall, wide lateral fireplace with chamfered bressummer. The windows have built-in seats with high sills. In the rear (service) room of the left-hand bay the vertical oak studs and sill plate of an original partition are visible; this was probably of post-and-panel type.
