Llysdinam

Llysdinam is a two-storey house built in the 1930s, designed in a free classical style. It is rendered with continuous parapets and has shallow slate roofs, punctuated by six rendered stacks arranged asymmetrically. The windows are hornless sashes with flat heads and narrow recessed mouldings.

The garden front, which faces south, is distinguished by a full-height Art Deco porch bow offset to the left. The porch features half-glazed double doors within a prominent rusticated surround, a flat-arched head with voussoirs and keystone, and a key block supporting the lintel of the upper-storey window. Rustication continues upwards around the window, tapering slightly. A recessed panel flanked by pilasters holds a stone coat of arms above the window. The ground floor windows are 9-over-9-pane sashes, while those to the upper storey are 6-over-6-pane. The garden front has three windows to the left of the porch bow and four to the right. Recessed panels extend above the upper-storey windows to the right, continuing to the parapets. Decorative cast iron rainwater goods are dated 1934.

The west side of the house, also facing the garden, has a central entrance with half-glazed double doors and flanking side lights, sheltered by an open flat-roofed porch supported on paired timber struts. A tripartite window sits above the entrance. Bowed projections with pyramidal roofs, featuring three 6-over-6-pane sash windows to each storey (the ground-floor windows being almost full-height), flank the doorway.

The east side of the house is advanced to the right, with four 6-over-6-pane sashes to the upper storey, featuring segmental heads and recessed mouldings. A stack rises from the parapets between the two pairs of windows. The lower storey has two tall sashes like the front, offset to the left. A flat-roofed porch with a multi-pane glazed door and overlight, facing south, sits in the angle of the advanced section, accompanied by a sash window to the east; there are no openings to the left of the porch.

The current main entrance is on the north (rear) side. To the right is a three-window block with a central panelled door under a flat porch canopy, with a small window to its left. The upper storey has 6-over-6-pane sashes. To the left is a long, split-level range partially built into the hillside. A half-glazed door leads to the upper storey, with two sashes to its right and three to its left. A half-glazed door to the lower level, reached by steps, is immediately to the right of the doorway. Sashes of variable size are found in the lower storey, and a tall sash is set in the east gable end. The end wall of the east range, with a hipped roof, is located at the far left.

Inside, a large stair hall is located to the west of the garden entrance and is also accessible from the main north entrance. This hall contains a 20th-century open-well staircase with pale wood, narrow balusters, and a turned handrail. Rooms lead off the stair hall, with the reception rooms on the south side. Panelled doors are found throughout, some 20th-century replacements, while others are from the 19th century and originally from Penllergaer.
