Former Stable Block at Plas-yn-Cefn

C19 loose boxes to the ground floor. The upper floor has a large room at the SW end, formerly the estate office and currently used as the hunt meeting room. This has a Tudor-arched stone fireplace with hollow stopped-chamfered reveals and carved guioche decoration to the spandrels; it bears the date 1694 in a raised shield, together with the initials IP.

Large rectangular 2-storey range of local limestone rubble, with slate roof and original kneelered and stepped gable parapets. The NW side faces the main yard, though its ground-floor is below the level of the yard floor and its upper floor is accessed via a wooden bridge from the latter; the ground-floor is reached via a flight of stone steps at the SW end, which lead down into a narrow, open passage. Here, to the L, there is an entrance with boarded door and 6-pane overlight; flanking this are two 9-pane sash windows, that to the R occupying the reduced opening of a primary cyclopean entrance, the huge reveals and partial relieving arch of which remain visible. The upper floor has a near-central entrance via a wooden bridge, with a brick cambered head and a boarded door. To the R are 2 large C19 9-pane (unhorned) sash windows with projecting. tooled limestone architraves, their reveals chamfered. To the L are three 8-pane sliding sashes. The SE side faces the lower, subsidiary, cobbled courtyard. This has a boarded door to the L with a 9-pane cambered-headed sash window to the upper floor; to the R are 2 modern windows with a C19 8-pane sliding sash beyond. Various earlier blocked openings are visible, including a former primary entrance and some (later?) ventilation slits. The NE gable has 2 fine, blocked cyclopean entrances with flat heads and a blocked primary window above with large exposed lintel.

Surmounting the roof is a large octagonal clock tower, a c1900 copy of the C18 original on the former laundry block. This is of timber construction with slate-hung lower section and slatted upper section; octagonal roof with very deep, moulded eaves and exposed rafter ends. The clock tower is surmounted by a lead ball finial and decorative iron weathervane with the Williams-Wynn initials.

Adjoining the range to the E is a small c1900 extension, forming an L-plan with the main block. This has a mono-pitched slate roof and wide boarded entrance to the SW; further boarded door to the NE. A flight of stone steps adjoins to the L (SE) of this and gives access down from the upper cobbled level of the laundry block to the lower level of the cobbled subsidiary yard.
