Description
Lleiniog is a two-storey house that dates back to the sub-medieval period, characterized by a long and low range on the left (south) side. The building features rubble masonry with grit rendering and slate hanging on the south gable, topped with a roof made of old small slates. It has a tall central chimney and additional stacks at each gable end. The façade includes five windows, with the current entrance located at the far right within a 19th-century lean-to porch that has trefoiled glazing. The windows are small-pane sashes; the first, fourth, and fifth bays have tripartite windows, while the ground floor has 16-pane sashes and the first floor has 12-pane sashes, all positioned just below the eaves. The slate-hung south gable features a distinctive spayed angle at the rear, with small-pane tripartite sashes.
There is a low rear wing, likely an early 19th-century addition, which has been extended and altered in the 20th century. A twelve-pane sash window serves as a stair window in the outshot rear wall of the main range, and there is a taller later 19th-century wing beyond. The later range to the north is significantly taller and has a canted plan, featuring 2-centred arched 2-pane sash windows on each facet, with French windows at the centre of the ground floor and in the return wall to the right. A massive triple rendered stack is located to the left.
The original range maintains a three-room plan, although the right-hand unit has been significantly altered to create a full-height stair hall when the north wing was added. The central unit retains a fine ceiling with a stop-chamfered longitudinal beam and similarly stop-chamfered broad joists, along with a chamfered bressumer over the fireplace and a boxed beam in the lower room. The roof structure of this range is intact, consisting of six bays with simple A-framed trusses of varying forms, some featuring collars. A later 19th-century staircase has been inserted into the end bay without disrupting the roof structure, coinciding with the addition of the north wing. The ground floor music room includes a marble fireplace and a high panelled and boarded ceiling.
