Plas Isaf

Large unit-planned, storeyed farmhouse of Z-plan. Of rubble construction with modern pebble-dash and slate roofs with deep verges and simply-moulded bargeboards; 2-stage red brick chimneys (c1900) with oversailing courses to capping. The main, NE range has a modern single-storey closed porch to its NE (garden-facing) side, with entrance at its L return. The first floor R window is a mid C19 12-pane sash, otherwise the windows are modern in C19 openings. The SE gable has a large segmentally-headed window to the ground floor, with plain casement section to its lower half and multi-pane glazing to its upper half. Small segmentally-headed window to gable apex, with late C19 plain casement glazing. A lower L-shaped range adjoins flush to the L. This has a modern gabled porch to the R, with a C20 part-glazed door within; C19 12-pane sash above. The return section has an entrance to the R with boarded door and a 12-pane casement above; to the L is a 4-pane late C19 sash. The gable end of this range has a modern garage extension; to the rear is a late Victorian brick gabled loading bay with moulded bargeboards, segmental entrance and boarded door. To the L is a 12-pane sliding sash at ground level. The N and W sides all have modern out-of-character windows.

The W range, forming the central section of the Z-plan house, has former hall (now sub-divided) with ogee stopped-chamfered ceiling beams and plain joists. The entrance hall, in the main, NE section, has a fine, large bolection-moulded wooden doorcase framing the entrance on the inside. This is of wooden construction (now painted) and has scrolled volutes to either side at the base and a tripartite moulded overthrow. Associated with this is an exceptionally fine oak stair, with barley-twist balusters, square newels and complex geometric finials; moulded string and rail and contemporary treads and risers. The stair is of dog-leg type with winders and segmental steps at the start of each flight (as at Plas Uchaf) and continues to the second (attic) floor (partly boxed-in). Associated with the stair is a dog-gate with flat, S-shaped balusters. This was found to be detatched and in the attic at the time of survey (1/98). The entrance hall has simple contemporary ribbed and panelled plasterwork to the ceilings and beams (mostly papered over); in the present kitchen (formerly the 'Parlour Mawr') there is similar simple plasterwork. The first floor retains good original random-width oak floor-boards and two contemporary ovolo-moulded pegged oak doorcases.
