Ty'n-y-Caeau including adjoining Agricultural Range

Farmhouse and agricultural range, linked together to form a roughly T-shaped complex. Of roughly-dressed limestone construction (the main faces whitened) with slate roofs. The farmhouse is of T-plan and consists of a main 2-storey, primary range of 3 bays, with a lower cross-range adjoining to the R. The former has a rendered facade and a colour-washed L gable end; plain stone end chimneys. Central entrance via a plain modern porch of rendered brick, open to the front; modern panelled door. Tripartite flanking windows to both floors, those to the ground floor with cambered lintels with rough-dressed voussoirs, and those to the first floor under the eaves. All save that to the ground-floor L retain their original 3-light leaded glazing with pegged wooden mullions; the latter has plain glazing. Further, 2-light leaded window above the entrance. The rear of this block has 3 further, similar windows, of which 2 have cambered heads, one with plain glazing.

The lower cross-wing has a long section advanced to the front and a shorter rear section connecting the house with the agricultural range. The front section has an end and central chimneys. Its SE (forecourt) side has a 3-part casement with 6-pane sections to the ground floor, with modern uPVC windows to both floors to the L. The NW (farmyard) side has a central catslide outshut with uPVC replacement window and a boarded entrance to the front (NE), via an extruded porch block with corrugated iron roof. Two further 2-part casement windows to both floors to the R, beyond the outshut; casement sections boarded, 2-pane, 4-pane, plain-glazed and small pane. At the far R, in the corner between the house and the agricultural range at right-angles with it, is a blocked, camber-headed entrance, stepped-up. Single rooflight to rear.

The agricultural range is of 2 storeys and adjoins to the NW. The left-hand section is a barn and has opposing barn entrances to the centre, each with cambered head. Ventilation slits are visible on both long sides and are arranged in 4 tiers on the SE gable end. To the R of this ascends an external stone stair, giving access to an upper hayloft via a boarded first-floor door with pegged frame. The loft has 2 square openings with boarded shutters; the ground floor, below this, is occupied by 2 large segmentally-arched cart bays. Beyond this are 3 stable entrances of diminishing heights, the outer ones with segmental arches; boarded doors. 3 boarded openings under the eaves, as before, with a further one at the far R above a wide cart bay, with expressed timber lintel.

The farmhouse has exposed ceiling beams to the former hall section (R of the entrance), with simple run-out chamfered detail. The barn section is of 4 bays and retains its primary queen post trusses.
