Llanfair-Isaf Farmhouse

Main range comprises principal room (the hall) in the upper bay to the L, and paired smaller rooms at the lower end to the R. Wide central through-passage (created at a slightly later date by re-siting the hall partition). Dog-leg staircase of early C17 type with splat balusters, runs to the rear R of the passage. Stop-chamfered joists to passage ceiling, similar to those of hall, confirming that this was once a single room. Most of the hall partition survives and is post and panel, but at the front of the house, a small pantry was fitted into the hall (probably in the C19); its tongue-and-groove boarded walls replaced the partition in this section. Principal room has fine ceiling with stop-chamfered main beams and similarly chamfered characteristically flat joists. The 2 beams lie against the partition, and corbelled out from the fire-place wall, with fireplace bressumer immediately behind. Fireplace has been partly filled in, with 2 cupboards to either side of existing hearth. At the lower end of the house, the original division into 2 small rooms survives: the rear room has been a hearted parlour and retains a (blocked) fireplace. Unheated front room has unchamfered flat joists (denoting its lesser status), and fine oak 4-panelled door. Stone wall separating these rooms from passage may be an insertion as it appears awkwardly underbuilt, with timber beam above: could the post-and-panel partition between passage and hall once have been in this position?

Upstairs, post-and-panel partitions separate central landing from the 2 principal rooms, and there is evidence that a further partition created a third central room. Shaped doorhead and heavy doorway (now ex situ) for upper room. Very substantial collar-beam trusses partially visible within walls either side of landing, and across the upper room.

Secondary hall house (hendy) has large partially blocked fireplace at gable end; traces of blocked window (with block lintel projecting into hall) at first floor corner of main dwelling. Two fine upper cruck trusses, and 3 tie-beams (one apparently a crude insertion?); that closest to fire-place having slots for joists, suggesting possible upper floor. R-hand truss has mortices for a partition, so this apparently single space was originally subdivided.

Georgian wing is planned like an independent house, but without any service accommodation, and connecting directly with the hall (kitchen) of the original dwelling. Essentially it comprises 2 parlours, and has small central stairhall. Staircase with stick balusters, swept rail and moulded tread ends. Half-landing to bath-room etc in rear outshut. R-hand parlour has fireplace on L-hand wall, in recess repeated on the other outer walls. Gothick detail to cast-iron fireplace, and moulded (perhaps painted slate) surround. Similar fireplace, also recessed, and with china-cupboard alongside it, in L-hand parlour. Both parlours and the bedrooms above retain reed-moulded cornices with rosettes at angles, and original joinery detail.

An irregular T-shaped group in which the main range (with the added lofted cartshed) forms the stem and is aligned N-S. Abutting the NW corner of this range is the slightly later hall house or secondary dwelling (known as the hendy). Projecting from the rear of the main range is the early C19 wing.

Main range is 2-storeyed, 2-room plan with near-central aligned doorways to through-passage. Rubble, roughly brought to courses; slate roof with end wall stacks that to upper end of massive dimensions. Entrance elevation faces W: doorway has riven stone voussoirs to arch; Windows are small-paned sashes (perhaps dating from the extension of house in early C19?): 20-pane sash to main room, 16-pane sashes elsewhere. Similar doorway aligned in rear wall, with 12-pane sash window on each floor to its left. C19 cart-shed addition is better-coursed stone, with hipped slate roof. It has 2 cart bays to ground floor, with slate lintels and central pillar. External stairs to first-floor doorway, with small window alongside and to loft above. Twelve-pane sash window to first floor in rear elevation, with blind-painted window below. Hall range (Hendy) at right-angels to front of main dwelling. It is a simpler form of construction, virtually dry-stone with small packing stones in the joints; slate roof with single chimney on L-hand end. Near-central doorway, also with riven stone voussoirs to arch. Small windows to either side, small-paned with stone lintels. Former stable (now cottage) attached to gable end of this range is 2-storeyed with external staircase to former loft against gable wall, central doorway in added porch flanked by 12-pane sash windows; small window above. Georgian wing to E is finely coursed and dressed stonework, its slate roof with pronounced overhang, hipped on the R-hand side. Axial chimney. This range is symmetrical in its main elevation, hence it appears like an independent dwelling with central front door with traceried overlight, in porch with flat moulded cornice, and flanking 16-pane sash windows.
