Pen y Bryn Farmhouse and attached Byre

Rubble construction, the house with roughcast render and the barn section with decaying lime-and colour-wash. No doubt thatched originally, now continously roofed in slate. The house is of lobby-entry plan with a plain rendered central stack. Originally symmetrical facade with central, recessed entrance . Late C19 stopped- chamfered doorcase with modern, part-glazed door. Flanking 12-pane casement windows on ground and first floors, the latter as gabled dormers, and that on the ground floor, to the R of the entrance of sliding type. Boarded external shutters to the ground floor windows. A further sliding sash to the R, unshuttered. In front of the house is a stone-walled enclosure which returns to the adjoining (later) wing to the R.

The agricultural section to the L is of 3 bays with king post trusses. Kneelered and parapetted gable to the L. This section has been largely rebuilt, probably in the late C18. 2 tiers of ventilation slits, all now blocked. Central entrance, stepped-up and with cambered head with sandstone voussoirs. Plain stable door. Flanking this under the eaves, 2 window openings, that to the L near-flush with cross-window, and that to the R with plain boarded shuttering. To the R an inserted C19 entrance with brick cambered head and recessed boarded door. To the L, towards the gable end, a further boarded door with ventilation slits. Corresponding central entrance to rear. Adjoining to L, stepped down and slightly recessed, a late C18 gabled extension. Rough- dressed sandstone under a slate roof, the gable kneelered. Segmental- headed entrance to L with recessed, contemporary boarded door. Segmental-headed unglazed light to the R. The L gable face has an upper shuttered window as before and ventilation slits. To the rear of the byre section a similar gabled extension. To the rear of the house, 2 later service wings of rubble, gabled and roofed as before. Modern fenestration, that to the L with brick chimney and boarded door, stepped-up at the junction with the main block.
