Plas Chambres, including adjoining forecourt and garden walls

Plas Chambres is a storeyed gentry house of timber-framed origins constructed in limestone rubble, with rendered principal elevations. The building forms a rough J-plan from two conjoined sections, each topped with steeply-pitched slate roofs. Each block carries two large lateral chimneys, three with gabled breasts, all with tall stacks.

The main front presents a central entrance with a chamfered and moulded wooden frame dating to the 16th or 17th century, fitted with a contemporary studded door later modified by the cutting of two vertical lights. The ground floor is lit by four late Georgian 12-pane unhorned sashes, with three similar windows to the upper floor set within hipped dormers that break the eaves.

To the left projects an advanced gabled wing featuring a similar dormer window to its inner return and two late 17th-century wooden cross-windows to the ground floor. These are plain-glazed except for one leaded light each. The gable end contains an early boarded and studded door with deeply-chamfered frame; modern casements have been added to the left and above. A single-storey 19th-century porch addition projects slightly to the left with modern casements. The south-west return side displays a large gabled lateral chimney and a flush lateral chimney to the left, with a 12-pane sash to the first floor between them and a further modern casement below.

The rear elevation features a gabled wing to the left with a late Georgian gabled extension, the latter containing a modern end chimney and a primary tripartite unhorned sash to its left return. A gabled stair projection rises between two lateral chimneys, beyond which extends a single-storey mono-pitched projecting wing. An open stone porch with steps down is extruded in the angle between this wing and the rear gable of the south-west wing, with modern windows to the rear.

The forecourt is enclosed by a sequence of walls approximately two metres high with late 17th-century sandstone copings. The front wall opposite the entrance is of limestone rubble and contains a later round-arched entrance with a boarded and framed door. The left and right-hand stretches are of brick dating to the late 17th century, the former having a rounded corner to the front. The right return passes the house, leaving a gap for a primary framed entrance flush with the façade and fitted with an old boarded door. The wall continues briefly before turning at right angles and returning as a broader limestone rubble wall to enclose a rectangular former garden to the side and rear. The north-east side of this forms a high revetment creating an elevated walled garden of the type favoured in the 16th and 17th centuries, and is doubtless of that period.

The house is currently divided into two units. The section containing the principal stair and parlour retains significant interior features. An entrance passage with small-field 17th-century Jacobean-type panelling leads to the primary parlour. The parlour displays fine late 17th-century large-field panelling, raised and fielded with bolection mouldings and a high moulded dado. A bolection-moulded doorcase with a two-panel fielded door, deep moulded cornice and panelled reveals, shutters and window seats complete the scheme, executed in softwood now painted. Opposite the entrance is an arched recess with archivolt and key, flanked by fluted pilasters and containing a coved niche with three shelves and a lower section with four drawers and two shelves. An unsympathetic mid-20th-century brick fireplace stands opposite the window; the original fine bolection-moulded and mantled fireplace surround formerly in this position is now located in the adjoining secondary house.

The parlour ceiling contains fine Elizabethan plasterwork comprising conjoined ribbed squares and rectangles with geometric, foliate and scroll decoration, including one female bust. Floorboarding is old random-width. At the end of the entrance passage a late 17th-century four-panel fielded door opens to the stairwell. The stair is a contemporary oak dog-leg with square newels and turned balusters, plain newel caps, and original treads and risers. At the top is a short returned balustrade and a depressed arch with chamfered wooden posts, probably reused from the late medieval hall. Two-panel Stuart doors are present. One bay of the former open roof is visible, though plastered over, in a first-floor room, with one tier of straight windbraces visible—two to each side.

In the other section, the hall remains visible with a wide late 17th-century stone fireplace featuring a bolection-moulded surround and stop-chamfered beams with ogee stops. A small ground-floor room off the hall contains a section of small-field 17th-century panelling against one wall, along with five further fielded panelled doors of late 17th-century date. A narrow well staircase to the rear features pierced, shaped balusters with square newels and geometric finials, now painted.
