'L'-Shaped Range of Farm Builings, including a Dovecote at Pen-y-Lan Hall

The 'L'-shaped range of farm buildings at Pen-y-Lan Hall includes a former cowhouse and a granary, along with a red brick dovecote. The cowhouse features a brick rear wall and a weatherboarded front, positioned at right angles to the west. The granary is located on the upper floor, also at right angles, originally forming the north and west sides of the farmyard. The dovecote is square in plan, two storeys high, with a pyramidal slate roof that has a decorative glover with external ledges and three flight holes on each face. It has a segmental-headed opening on the ground floor and a semi-circular light on the upper level, which is now glazed, and open eaves.

The cowhouse and granary range to the west is a single storey with three bays, featuring a timber weatherboarded front wall on stone footings and a hipped slate roof. The roof has a single purlin that is windbraced on the front pitch, with tie beams at eaves level that are interrupted for a through passage. The brick dentilled eaves add to its character. Originally, the building was floored, and the brick rear wall includes three semi-circular lights with radial glazing bars, along with a small 20th-century lean-to attached at the corner.
