Outbuilding to the rear of Derfel Gadarn

Rectangular one-and-a-half storey building of local rubble construction on a high boulder-rubble plinth. Steep slate roof with rectangular end chimney to the L gable. This has weather coursing and a cornice band; its upper section is a C19 rebuilding. The main (SE) side faces a small garden. This has 3 irregularly-spaced entrances, associated with use as a stable, with outer window openings to those at L and R; chamfered and pegged frames with boarded doors, pegged window surrounds. The upper floor has 3 further windows: that to the L has 4-pane early C20 glazing, that to the centre has a C19 or early C20 re-used 6-pane window and that to the R is framed and boarded; all have projecting stone sills.

The rear (NW) elevation backs onto the lane and has a single pegged, framed window to the L. The N (lane-facing) corner of the E gable is chamfered to follow the lane. Boarded loading bay to the upper gable, with expressed wooden lintel. The W gable has a first-floor boarded entrance accessed via a flight of 7 stone steps. Adjoining the main building on the NW corner is a C19 rubble and slate outbuilding. This is whitened and has a central boarded door with flanking windows; 4-pane casements with stone sills. A lean-to addition with boarded door adjoins this to the W.

Stone-flagged floor; plain C19 purlins to roof. The left-hand section (a former hall) has whitened walls and a roughly stopped-chamfered main ceiling beam with plain joists (some replaced). Fireplace with wide, stopped-chamfered bressummer; C19 oven. Original raised sill to window with wooden seat. The right-hand section has roughly-chamfered ceiling joists.
