Nant Pasgan-mawr

The house is structurally articulated by the two pairs of collared cruck trusses which are embedded in the stone walls and carried on slightly projecting pad-stones. The trusses have pronounced elbows, and that over the hall is seated higher in the wall than the truss between hall and service end. Cross-beams supporting the ceiling lie alongside the trusses but are not jointed into them. The roof has two tiers of purlins, the upper of which lie directly on the cruck-blades, but the lower purlins are supported on short spurs above the blades. The house retains significant elements of its early arrangement, notwithstanding loss of partition between hall and service end. The arrangement of mortices in the beam between service end and hall passage indicates that the service end was once divided into three small units. These may have been parlour, buttery and stair - a trimmer beam for a staircase survives; there is also evidence of a small fireplace, suggesting that one of these rooms was a small parlour. Hall and service end are differentiated by the level of detail in the ceiling: hall (including passage bay) has chamfered joists, whilst there are plain joists to service end. Fireplace bay of hall now lacks ceiling, but slots for joists clearly visible in central cross-beam, and on both sides of a further beam set just forward of the chimney (giving weight to the suggestion that in its present form the fireplace is not primary). Staircase alongside hall stack; the hall fireplace has chamfered timber bressumer; inset within it is a bread oven and grate, which has round-headed archway through smoke-screen wall, crane, and ash-pit. Substantial fireplace with similar bressumer to first floor chamber over service end. Slots in the collar of the truss at this end indicate the position of a partition delineating a first floor chamber.

Addition against SW gable has flue in rear corner - perhaps once serving a wash-boiler or drying kiln.

A long and low building, retaining hall-house proportions, with in-line extensions to each gable end. Roughly coursed rubble stone walls on projecting boulder footings, with slate roof. Fine chimneys mark the original gable ends, with a further very similar stack on the NE gable end: all three have drip-stones and traces of over-sailing caps. Doorway off-set to left of centre, with fine voussoir-headed archway. Windows to either side (2-pane sashes in earlier openings); 3 catslide dormers(reconstructed in the later C20) not quite aligned above. 3 small windows to rear, that to centre aligned with entrance, and probably replacing an earlier cross-passage doorway. Extension against NE gable has single dormer window, and doorway in gable end. Loft doorway at rear, accessed by rebuilt external staircase. SW extension has doorway in front elevation, and wide pitching door to upper rear. Lean-to against rear is also a later addition, and probably served as a cattle shelter.

The house retains its context amongst small fields with the remains of several field cow-houses.
