Plas Isa

Plas Isa is a two-storey, T-shaped house incorporating whitened red brick and a timber-framed core, dating to the 17th century with later alterations. The roof is slate, with modern bargeboards. Chimneys project at the ends and centre, featuring offset, dentilated cornicing and paired, offset chimneys which are unwhitened. The asymmetrical front facade is divided into three sections. The central, gabled section displays exposed 17th-century lozenge-framing, also with modern bargeboards and a weathervane; a modern boarded door sits below, with a triangular glazed overlight and a modern bracketed wooden porch-canopy. A slightly lower wing, set back to the right, has no front-facing windows but features modern tripartite wooden casements to both floors of its gabled return. Flush with the entrance bay to the left (beyond a vertical break in the brickwork) is a further section with three ground-floor windows: the nearest is a small horizontal window with a cambered head, followed by two slightly recessed four-pane casements; two similar windows are positioned to the first floor, under the eaves. The garden side (facing northeast) has two pairs of multi-pane French windows to the recessed main section on the right, both with boarded shutters. Further single and tripartite windows, similar to those on the front, are found to the ground and first floors. An L-shaped glazed verandah, dated circa 1900, adjoins this side, supported by four stopped-chamfered wooden posts with curved bracing, and featuring a red/black quarry-tiled pavement with sandstone kerbing. On the southwest side, a tall gabled projection rises from the first floor, with a modern casement. Further casements are present on both floors of this and the returned section, and a modern multi-pane glazed door is situated to the left. A high rubble plinth is visible on the original section. A modern two-storey brick cottage and garage extension adjoins to the southeast.

The single-bay hall was originally open, and is now characterised by a stopped-chamfered beamed ceiling. A good primary post-and-panel partition separates the hall from the parlour, facing a large fireplace. A stopped-chamfered bressummer is present, now partially modernised. The current entrance is located at a half-landing level, with short stair-flights providing access to both the upper and lower halls. A fragment of an original, early 17th-century oak dog-leg stair exists leading down to the lower hall; the upper flight and its short, returned gallery are modern replicas of the original style. The staircase features flat, shaped balusters, a moulded rail and square newels with ovolo-moulded decoration; the string of the upper flight exhibits relief-carved guilloche decoration, mostly original. An open upper section to the hall reveals mostly original roof timbers and a small modern King Post insertion. A partition truss at the parlour end contains a blocked primary opening with a segmental head, and a modern boarded door in the centre. A fireplace at the stair end has sandstone ashlar jambs and a chamfered bressummer. The ground-floor parlour has first-half 17th-century small-field panelling on the post-and-panel partition wall, and simple ribbed plasterwork decoration to the ceiling, along with an exposed, chamfered main beam that is heavily keyed, formerly plastered.
