Cefn Llwyn

Cefn Llwyn is an Arts and Crafts style house of two storeys with attics, notable for its characteristic asymmetrical form. The building is rendered with large areas of grit render, smooth render in the gable apexes, and roughly dressed stone plinths to the bay windows and entrance wall, with sandstone dressings throughout. The roof is covered with small green slates and red clay ridge tiles, with broadly projecting eaves supported by ornate scrolled iron brackets. Tall rectangular chimney stacks, grit rendered with brick corbels to the capping, rise to the right of each gabled bay at the front, with a single ridge stack serving the servants' quarters to the rear; the front stacks have gabled steps at the base of their front faces.

The house is planned with principal rooms facing front, the entrance recessed between two gabled bays. The entrance features half-glazed double doors with Art Nouveau-style leaded glass and floriate brackets to the right, while to the left stands a tripartite window of three leaded lights with chamfered mullions. Set in the roof above the entrance is a flat-roofed dormer with four small-paned lights. Other windows throughout are small-paned horned sashes. The right gabled bay has a ground floor canted bay window with a shaped leaded roof rising to a canted oriel above. The left gabled bay contains a ground floor canted bay window, a first floor tripartite window, and a circular leaded light at first floor level to the left. The left return elevation features a tripartite window to the right and a gabled bay to the left with similarly detailed windows to those of the front elevation's right gabled bay; the rear elevation of this gabled bay contains a large stair window of three rows of four leaded lights. The right return is abutted by a flat-roofed garage block containing two garages with large boarded doors; the ground floor has a single window to the left and a canted bay window to the right, while the first floor has a tripartite window to the left and paired windows to the right. To the rear of the main house is a gabled wing with entrance in a gabled porch to the north side.

The interior is planned around a central hallway with principal rooms in the front block and service rooms and servants' quarters to the rear. The entrance leads into a small vestibule with cloakroom to the left, both with mosaic patterned floors. The hallway features a corbelled picture rail and a timbered arch over the first step of the stairs. The dog-leg staircase has tapering splat balusters, some pierced with shaped motifs, and square newel posts with projecting caps. The ground floor rooms retain picture rails, with the sitting room having a corbelled rail. The dining room and drawing room contain their original fire surrounds. The dining room fireplace has a wooden surround with tiled inset, a widely projecting moulded cornice on tapering Ionic columns with fluting to the heads, and an oval mirror set above the corbelled mantle. The drawing room has a similarly detailed surround with plain tapering columns. Some bedrooms retain original cast-iron fireplaces, some with floriate decoration. The bathroom retains original fittings and tiling, and the pantry retains some original glazed cupboards. Many of the panelled doors throughout are original and retain their Art Nouveau style floriate handles.
