Gregynog Hall

Gregynog Hall is a large house, largely dating from the late 18th century, with significant alterations and additions in the 19th and 20th centuries. Constructed in an "E" shape, it has three main storeys plus attics with gabled dormers and slate roofs; tall stone chimneys have been lost. The external appearance is of half-timbering, but this is achieved through rendered concrete moulded and painted in a black and white style. The main front has seven windows and is characterised by a central gabled porch which extends to attic level. The porch is faced in stone, featuring a Tudor-headed doorway and buttresses. Single-window bays flank the porch, with advanced bays interspersed with recessed bays. To the right is a two-storey stone link leading to a music room, which has a Tudor doorway and a first-floor balcony. The music room itself is timber-framed and has three large mullioned and transomed windows with timber-framed gables. The left elevation of the main block has three windows and two gabled dormers. The rear elevation is asymmetrical, featuring five gables and mainly small-pane hornless sash windows, though it incorporates a stone bay window to the library and a stone mullioned window to the dining room. To the north are two black and white wings at right angles, two and a half and three storeys in height. A flat-roofed block in red-brown brick from the 1960s sits between the wings.

The porch features oak panelling and a half-glazed entrance doorway. Inside, a transverse corridor runs the length of the house, with rooms opening to both the front and rear. The main hall is oak-panelled with a ceiling of moulded plaster beams, a fireplace to the left, and an archway leading to the rear staircase. The full-height staircase in the stair tower has stone treads and a handrail moulded into the wall. The drawing room, located on the front left, is divided into two sections by an elliptical archway. It has a ceiling with moulded ribs, two classicising fireplaces, and coved corners. The library, at the rear, features a ribbed ceiling of intersecting circles and a bay window. A smaller library on the rear also has a moulded ceiling in a star pattern. To the right of the hall is the dining room, known as the Blayney Room, with elaborate 17th-century panelling originally from the earlier house, with later 19th-century additions to fit its new location. The panelling bears the date June 22, 1636. A particularly elaborate fire surround and overmantle includes paired end columns, heraldry, and relief figures. The remaining walls are adorned with heraldic shields within arcading, supported by tapering pilasters, framing relief panels, an arcaded serving bay with mirrors, and four elaborate doors above which are fields with dates. The corridor leads to the music room, which has an open roof of arch-braced trusses and a stage to the north. The majority of the ground floor rooms are now offices, situated between the rear wings. Most rooms on the first and second floors retain simple cornices, and boast original panelled doors. The attics were converted to offices in the late 20th century.
