Coach-house and adjoining Entrance Arch to Plas Brondanw Gardens

L-shaped coachhouse of rubble construction, with steeply-pitched, graded small-slate roof and tiled ridge; feathered eaves. 2-stage wooden cupola to centre of main block, its boarded lower half with lozenge-glazed rectangular panels and painted clockfaces; octagonal open arched lantern to upper stage with sloped copper roof and surmounting ball finial. The main section has 2 round-arched entrances to the SE (lane-facing) side, with deeply-recessed boarded double doors. The garden side has an arched entrance with steps up to a recessed, part-glazed door and a tall, 10-pane window to the L; the SW gable has a tall arched loading bay with boarded oak doors and a CWE eagle cartouche (for Clough Williams-Ellis), in reconstituted stone, above; 9-pane recessed window to L. The subsidiary section is lower and partly overlaps the NE gable of the main block to form a gabled cross-wing advanced to the lane side. Round-arched entrance as before to its lane-facing gable, with cement-stone lion mask above; to the R a small, square light. The long NE side has a deeply-recessed oak boarded door to a round-arched entrance and an 8-pane casement to the R; beyond, a wide, plain opening with boarded double doors. The upper gable of the main block is slated and feathered onto the NE pitch of the lower wing's roof; within is a segmental window with intersecting tracery.

Adjoining flush with the lower wing's front, lane-facing gable is a high rubble wall; this hides the R roof pitch of the advanced wing and continues to the R to form an arch; projecting rubble keystone, plain rivetted iron gates with shaped top.

Plain interior.
