Glan-y-wern Hall

Glan-y-wern Hall is a largely 18th-century house, with later additions and alterations, exhibiting group value. The main body of the house is two storeys high and seven bays wide, constructed of local limestone ashlar masonry with concealed slated hipped roofs. It faces south-east onto a gravelled forecourt, and the principal garden elevation is to the west, also of seven bays. The ashlar masonry of the front, west, and north return elevations is laid in graded courses. The south elevation has a modest cornice and blocking course, while the west elevation features a raised centre to the blocking course above the central three bays, which are slightly advanced. The windows on both main elevations are hornless sash windows: 12 panes upstairs and unequal 15 panes downstairs. Most are believed to be original, in hardwood with original hand-made glass, though some have been reglazed with conservation quality glass of similar appearance.

A central, single-storey porch of limestone ashlar, designed by Nesfield, projects from the front elevation. It has clasping corner pilasters beginning at sill level. A seven-panel door is set within an eared architrave, with heraldic panels above, and there are sash windows to the left and a fixed light to the right. A rendered bay and a section of older brickwork join the main house to the north. The original brickwork of the older house is visible only at the north, and includes shorter wings with hipped slate roofs. One lower window in the left wing has simplified Venetian detailing with timber mullions; the others are primarily 12-pane sash windows. A three-storey rendered section, also part of the original house, extends from the east elevation, exhibiting irregular window placement.

The layout of Glan-y-wern was influenced by the need to incorporate the older house, but largely adheres to a symmetrical design around two axes. Entry is via the central porch on the south elevation, leading into a large hall with two scagliola columns that screen the doors to the central staircase and service areas. The stone staircase is centrally placed, but turned 90 degrees. This is a particularly important feature, with a single lower flight and twin return cantilevered flights, a hardwood handrail, and ornate cast iron balusters. A glazed cupola sits above the stairwell.

To the left of the entrance is the first of three similarly decorated reception rooms, of high interior quality, that run the length of the west elevation; the central room is the drawing room. These rooms feature restrained plasterwork in an Adamesque/Regency style, with repeated Prince of Wales feathers in the cornices, and Classical marble fireplaces. To the right of the entrance is the dining room, and the rooms are connected by mahogany double doors.
