Plas-y-bont

Plas-y-bont is a house dating back to the late 17th century, with later additions and alterations, situated on an irregular plan. The house is constructed of rubble stone with slate roofs, with the rear wing having a grouted finish. The front range is long and irregular, with a prominent rear wing.

The southern block, dating to the late 17th century, has a cross-gabled south end that abuts a lower, older section to the north, incorporating the original south chimney. A brick stack on the south side has been removed. The eastern front features stone slab lintels over the windows; a nine-pane loft window is set in the gable. There are two earlier 18th-century sash windows with thick glazing bars on the first floor, alongside two ground floor casement windows. The south end has no windows.

The older range to the right has a square south end stack with a projecting top, and a three-window range of 19th-century four-pane sash windows, with a ledged door positioned off-centre. Timber lintels are above the windows, with slate lintels below. A stone ridge stack is situated to the right. A later addition to the north continues the ridge line, with a large stone stack at the north end. This section has two ground floor casement windows and a small window alongside the chimney. The rendered north end wall has no first-floor front windows.

The rear of the long range has a varied arrangement of windows, largely from the 20th century at the northern end, with sash windows similar to those on the front within the central range. A large wing to the rear of the southern block, of the same height, abuts the main chimney on the east side and has a stone west gable stack. The north side has two four-pane sashes set to the left, a boarded door in an angle with a stone lintel, and a 20th-century window to the right. The west gable features two small loft lights, a first-floor 12-pane sash to the right, a leaded window to the left, and a ground floor six-pane window to the left. The south side features a four-pane sash to the first floor centre, a 12-pane casement lighting the stair in an angle to the right, and a six-panel door.

The main central room in the original range has heavy, rough beams and blocked fireplaces. The rear wing contains a fine, late 17th-century dog-leg staircase with four flights, featuring a closed panelled string, square newels with carved pendants and finials, a moulded thick rail, and turned thick balusters on the first two flights. The upper flights have flat balusters. A heavy oak timber-frame partition is positioned to the west of the stair. The first floor centre (not seen) is said to contain stop-chamfered spine beams with run-out stops. The west block is said to contain an early 18th-century panelled room with painted pine panelling, a fielded panelled door, and a panel above the fireplace intended for painting. Heavy roof trusses are present throughout, including a pegged collar truss over the stair and a double purlin roof. The south end features a diagonally-set heavy ridge beam.
