Llanfair Hall including attached courtyard ranges and all subdivided units

Llanfair Hall is a complex, multi-period country house with stuccoed walls, slate roofs, and mid 19th-century corniced stuccoed stacks. The oldest part is a short rear south-east wing, which was refaced in the mid 19th century as the right bay of the irregular four-bay south-west entrance front. The entrance front displays Italianate detailing, continuing around the corner in a broad three-bay north-west frontispiece projecting from the end gable. This gable forms the right end of the north-west garden front, linked by a plain one-bay range to the dominant four-storey left end tower dating from circa 1860–1880. A two-storey rear wing with attic, of uncertain date but possibly 18th century or early 19th century, runs parallel to the entrance front and extends back from the tower.

An L-plan two-storey outbuilding range in squared pink rubble stone extends north-east from the tower, returning south-east to enclose the upper end of the yard.

The south-west entrance front displays mid 19th-century detailing unified by a broad band. To the right, set back, the refronted original range has a parapet, nine-pane upper sash and 16-pane lower sash windows, with a narrow blank panel above the upper sash and a 19th-century stack at the wall face behind the parapet. A right end gable stack completes this section. The remainder of the entrance front has a single roof line with a central stack on the roof slope and an axial stack at the join to the earlier range. A broad gable to the right contains a 12-pane sash above and a five-15-five pane sash below, followed by a projecting porch with heavy detailing of circa 1860–1870, featuring an inset entry with pilasters, moulded arch, keystone, and panelled spandrels, topped by a heavy bracket cornice with panels between paired console brackets. Above this, projecting slightly under the eaves, is a six-pane window. The left side continues the band, but the windows at both floors have been altered to metal casements of circa 1950.

The right façade of the garden front displays a broad shallow gable from which projects a two-storey, three-window frontispiece with giant pilasters. The original cornice has been altered to a slate pent roof. Four-pane sashes in architraves occupy the upper floor above a band, with moulded arched French windows below, detailed similarly to the porch. To the left, a slightly recessed one-bay range has its roof parallel to the garden, with a similar first floor sash and an altered French window at ground floor. The tower to the left is rectangular in plan, tall, four-storey, and displaying Italianate detailing. It has a two-bay front and three-bay sides. The front contains a ground floor Venetian window with an arched blind head, and four-pane sashes in corniced architraves to the next two floors, separated by bands. The top floor is more ornate, with paired pilasters at the angles and between unmoulded arched windows, a full cornice, and an iron railing to the flat roof. A large south-west wall external stack and a south corner stack complete the exterior. The rear and north-east side feature matching upper floor detailing, though the windows are blank except for the right opening on the north-east side.

The rear courtyard displays the rendered side of the original south-east wing with varied fenestration, including a first floor timber four-12-four pane canted oriel. Linked at diagonal angles only is the rear wing occupying the angle behind the two main front ranges. This displays proportions suggestive of the 18th century but retains no early external detailing. A brick left end stack marks its two-storey, two-window north-east side, with one upper window partly obscured by the end of the service and outbuilding range, which must therefore be later in date. The ground floor has a glazed door and a broad 36-pane sash. A 20th-century eaves dormer is present.

The long, low two-storey service range is stuccoed where it forms a lean-to against the rear of the tower, but otherwise constructed of stone. Two ridge stacks and four widely spaced first floor windows—three of them broad 20-pane sashes—characterise this range. The ground floor is more varied and has been altered, though original openings retain stone voussoirs. The return wing has three similar first floor windows and a four-bay ground floor.

Interior

The porch opens into an outer hall with a fluted frieze and Victorian Adamesque ceiling ornamentation featuring a central rose within a concave-sided diamond and oval-ribbed border. A later small-pane screen divides this from the inner hall, which contains a simple early 19th-century staircase with scrolled newel and swept-up handrail. A former strong-room beneath the stairs is said locally to have been used during the war for the safe-keeping of prime national treasures.

The main ground floor south-west room served as the drawing-room and is lit by the three-window bay. It retains an original ornate 19th-century cornice, though the ceiling roses are modern. A blocked door stands to the right of a timber chimneypiece with acanthus moulded and shouldered fireplace. The smaller dining-room to the right contains two round-arched recesses, reflected in the bedroom above. Panelled shutters and four- and six-panel doors are evident throughout. The top-lit stairwell has a broad landing and a blocked archway to the tower.

The oldest part, the south-east wing, lies separate to the right of the main stairwell. It contains a fine oak-panelled room of the early 18th century with fielded panels above and below the dado rail, a moulded cornice, and shallow skirting. The fireplace features a later plain surround with a later 18th-century iron grate, but retains an original large bolection-moulded raised panel above.
