Plas Aberllefenni

The house is of 'L'-plan built of grey slate cut and coursed above a rubble plinth, and roofed with slate. The main facade faces S, but has, at the left end, an earlier 7 x stepped gable end on kneelers, with offset at first floor ceiling level, terminating with a stack. The masonry of this wing extends to the rear to another stepped gable end to the wing. The facade is of 2 storeys, 5 window bays, with a central entrance approached by 4 steps, two semicircular, leading up to the 4-reeded panelled door with overlight, all within a Classical porch on slender octagonal slate columns. Both floors have large and closely spaced 12-pane horned sash windows, with slate sills and lintels. Coved slate eaves. At the rear of the main front, a small coped gable with a stack, and the re-entrant angle is filled with a large service lean-to. Three inconspicuous roof lights. Some blocked windows in the left gable end, and 1 12-pane sash window to each floor in the rear wing, with a blocked window over the side entrance.

Entrance opens directly to the reception hall, with stair off at rear, a early C17 newel stair open well stair with turned balusters. Living room to left, with a fine strongly-modelled slate fireplace in the gable end. Plastered ceilings, with a number of heavy chamfered cross beams with bar stops, also late C16 or early C17. The partition to the present kitchen on right of hall is probably original. In the rear wing, on the first floor, a chamber with fine bolection moulded panelling, chair rail and cornice. Some original C16-C17 panelled doors. Stair to roof, which has C16-C17 collar beam trusses to both front range and rear wing, some wattle and daub partitions, and at the rear gable end, a remarkable moulded late C16 door.
