Description
Llwyn-onn, also known as Llwydiarth Old Vicarage, is a two-storey house with a square plan, built in the 19th century. The exterior features axe-dressed uncoursed masonry, with the front elevation made of larger stones and the rear elevation covered in slate. The house has hipped roofs that are finished with metal over the hips and tile ridges, along with two rendered chimneys. The walls at the side entrance have been painted white.
The front of the house has three windows and a central door located in a porch that has stone walls and a hipped roof. Above the door, there are two-light small-pane windows with iron glazing bars and opening lights, although the window on the left has been re-glazed without glazing bars. The window below on the left has been walled up, while the window on the right features a mullion and transom design with small panes.
The rear and south elevations maintain their small-pane windows, with the surrounds of the rear windows standing out from the slate hanging. These windows also have mullions and transoms, and the lower windows on the south side are topped with cambered arches.
To the north of the house is a two-storey stable and cowhouse built in a quasi-rubble style, running east to west. The roof has been replaced with corrugated steel sheeting. The stable door, which has a segmental arch, faces the house, and there is a boarded loft hatch above it. This range is connected to the house by a single-storey link made of similar masonry, featuring a slate roof, a door, and a two-light small-pane window with iron glazing bars and an opening light.
Inside, the layout is symmetrical, with the main reception rooms located on either side of the entrance hallway and stairs.
