No 9 Llannerch Hall

Large country house of irregular plan, mainly of three storeys plus basement, constructed of stuccoed limestone and red brick on a chamfered plinth with fine sandstone dressings. The roof comprises shallow-pitched, hipped slates with lead flashings, and tall 19th-century brown brick chimneys with oversailing courses and dentilated tops.

The main south-east front presents a symmetrical 3-bay primary section with a recessed central entrance bay flanked by full-height square projecting bays. The central bay features an advanced single-storey classical tripartite entrance section, nearly flush with the flanking bays and topped with a decorative balustrade to its flat roof. A central Tuscan portico with moulded, round-arched entrance and projecting key and imposts is approached by 6 moulded steps leading to 4-panel double doors with glazed upper sections and facetted lower panels. A moulded entablature and cornice are returned onto narrow flanking sections containing plain 19th-century sashes with projecting stone sills. Tripartite sash windows light the flanking bays on the ground and first floors, with those to the upper floor supported on consoles and topped with pediments, while those below have moulded labels. Plain sill-corbelling appears throughout. Four-pane French windows to the first-floor central section have simply-moulded entablatures; similar second-floor windows incorporate volutes to the sides. A fine moulded and dentilated cornice, dating from the 1770s, runs across with 2 contemporary lead downpipes featuring simple decorative hoppers to the inner returns of the projecting bays.

The north-east garden front displays plain, unhorned sashes and architraves; a continuous cornice runs throughout. The main section extends 4 bays deep with the return walls of the frontal bays recessed and a similar single-bay section to the right advanced on either side of a 2-bay main section. Basement access features plain railings with a segmentally-arched entrance and window to the right, and a part-glazed door. Adjoining to the right and advanced again is a 2-storey L-shaped addition with cornice matching the main house. The ground-floor main section has a plain tripartite window, and paired sashes light the recessed single-bay section to the right.

The rear elevation exposes random limestone rubble walling to the main block, a Jacobean feature, with a cornice and 18th-century windows as before. To the right stands a tall 4-storey plus basement wing of red brick, an 18th-century addition with a modern flat felted roof to the upper storey. The first and second floors feature 12-pane windows set nearly flush, with fine brick voussoirs. Blocked windows appear to the left on the north-east side. A small light well between this projection and the rear of the main block contains 19th-century and modern single-storey additions in front.

Adjoining flush to the main block on the south-west side is a 2-storey, 3-bay 18th-century range, stuccoed and roofed as the main block, with dentilated and moulded cornice. The roof carries a parapet with a 19th-century pyramidally-roofed wooden bellcote and tin louvre, and 2 staged 19th-century brick chimneys. Both floors feature 18th-century segmentally-arched windows facing the front, with plain projecting sandstone architraves, their sills, heads and centres quoined, and projecting keystones.

Stepped down and adjoining to the left is a single-storey mid-19th-century addition of uncoursed limestone ashlar with a roof hipped to the left. A moulded cornice and plain stringcourse are followed by a window as before, copying the 1770s work; this has been lowered and now serves as a modern glazed entrance with a further modern window to the left. Four 9-pane sashes (modern replacements of 19th-century originals) to the south-west end have projecting sandstone lacing; a 2-stage brick and sandstone chimney rises above. The long south-west side of this range extends 5 bays with windows as before to the first 3. The two right-hand bays accommodate a storeyed modern addition, while a similar flat-roofed brick addition occupies the ground floor of the left bay, with a basement addition to the right.

Adjoining this 18th-century range to the rear (north-west) is an early 19th-century 2-storey red brick addition with a wide canted storeyed bay to the south-west. This carries a hipped slate roof with lead ball finial and dentilated eaves, and 12-pane modern tilting sashes light the original first-floor openings with projecting sills; modern windows and a door illuminate the ground floor. An early 20th-century hipped-roofed red brick garage addition adjoins flush to the left. Fronting is a continuous mid-19th-century open slated pentice forming a single-storey covered way, supported on cast iron columns set on low brick walls with sandstone copings. This extends to the left to include a segmental carriage arch providing access to the rear.

The entrance hall features an 18th-century decorative floor of conjoined limestone flags with inset black marble squares. A dentilated plaster cornice frames a compartmented ceiling with a classical frieze of triglyphs and rosettes, and vertically-panelled dado rises below. A 19th-century tripartite wooden vestibule screen with tall 4-panel double doors has the upper panels leaded and flanked by classical pilasters, with heavily-moulded cornices and facetted decoration to plinths. A full-height cantilevered stone corkscrew service stair from the 18th century adjoins; panelled doors and door and window reveals continue throughout.

At the end of the entrance hall, a fine 1770s staircase sequence ascends from the ground to the second floor. The first section, from ground to first floor, was originally a narrow well stair with quarterpaces and a first-floor galleried landing; the well was infilled in the 19th century to form a service passage. The second stage, from first to second storey, is a large sweeping well stair with corkscrew flight. Oak treads and risers feature scrolled and moulded tread-ends and fine octagonal oak balusters with stopped-chamfered decoration; elegant swept, moulded mahogany handrails end in spiral twists with columnar balusters. Large stair windows to each floor incorporate heraldic stained glass, those to the ground and first floors dated 1867. The ground and second floors contain windows incorporating fine 17th-century enamelled quarries and some 18th-century enamelled heraldic panels.
