Labourers quarters and agricultural range, Tre Gof

This is a range of labourers' quarters and agricultural buildings, built in the 18th century at Tre Gof. The range follows an L-shaped plan and originally included a lofted cartshed, stable, cowhouse, loose boxes, barn, and servants' quarters, with later additions of a pigsty and hammels (covered livestock pens) to the rear. The building is constructed from local rubble masonry with a heavily textured mortar, and has slate roofs, with tiled copings on the cartshed and barn, and a brick ridge stack with an advanced cap on the servants' quarters.

The western arm of the range consists of a lofted cartshed, a stable, and a cowhouse. The cartshed, at the southern end, has a two-unit pigsty built behind it. The front (east) elevation features two wide, elliptically-arched cart bay openings with boarded doors at the northern end, and a small two-pane window to the south, all with roughly shaped stone voussoirs. Two small loft windows are set beneath the eaves. The rear (west) elevation of the cartshed has a single doorway with a brick lintel to the south, and a small two-pane window to the left of the door, also set under the eaves. A two-unit pigsty, built at a right angle to the rear, is constructed of rubble masonry with a pitched slate roof and a brick front wall with slate-lined feedchutes and a slate coping. To the right (north) of the cartshed is a two-bay stable, and a two-bay cowhouse and loose stall contained within the northeast angle of the range. A three-bay hammel was added to the rear of this northeast angle. The stable and cowhouse are built at a lower level than the adjacent buildings. Openings have brick lintels, and windows feature six-pane lights with brick sills and boarded doors.

Abutting the eastern end of the northern arm of the range is a taller, four-bay barn. The front and rear elevations of the barn each have central, opposing, elliptically-arched openings with roughly shaped stone voussoirs, slightly advanced keystones, chamfered gritstone jambs, and boarded double doors. Flanking the doorways are narrow ventilation slits, some of which retain slate louvres, and the corners of the barn are accentuated with large gritstone quoins. Built at a lower level, abutting the east end of the barn, are the former agricultural workers' quarters, with an adjoining loose stall and calf shed at the eastern end. The accommodation block is a two-unit, single-storey structure, with a doorway offset to the left (west). The front (south) elevation has openings with roughly shaped stone voussoirs and plain stone lintels, while the rear elevation has plain stone lintels. The eaves overhang.

The roofs of the main L-shaped range are exposed, with some having decorative roof timbers ("torching"), and include roughly sawn collared trusses. The hammels have king-post trusses. The stable has a loose box in the northwest corner, with boarded sides and a doorway across the corner, surmounted by a railed grille. The barn retains remnants of line shafting along the rear (north) wall, including four drive belt wheels. The agricultural workers' quarters have quarry-tiled floors and the remains of simple fireplaces.
