Description
Llys Llewelyn is a mid-19th century two-and-a-half storey town house designed in a simple Tudorbethan style. It is built of rough-dressed slate with slate-stone dressings and features a modern slate roof with plain bargeboards along deep verges. The house has three plain chimneys with weather-coursing and plain cornices.
The entrance is located on the south side, accessed through a simple open flat canopy porch, and features a 19th-century four-panel door with glazed top panels. To the right of the entrance is a 10-pane vertical sash window, which has a plain label above a large slate lintel. The first floor has smaller windows with eight panes, each with a plain cill-band that wraps around to the main road-facing front. There are also two similar windows in the attic, which have pointed glazing bars in the upper lights and projecting cills.
The road-facing elevation has two bays. The left bay features a storeyed, canted bay with central windows as previously described, flanked by four-pane vertical lights and topped with a semi-octagonal roof. The right bay is gabled and slightly advanced, with tripartite windows in the slightly projecting central section on the ground and first floors. These windows have an eight-pane central light and four-pane flanking lights, with a cill band on the first floor and a moulded string course beneath it. An arched sash window is present in the attic with a projecting surround, and the eaves cornice is moulded with a plain band beneath.
The interior was not inspected during the re-survey in January 1996.
