Courtyard stable block at Mynachdy

The courtyard stable block at Mynachdy is a U-shaped structure that, along with an attached stone wall, encloses a stable yard. The central section is single storey, while the two wings are two storeys high. The walls are made of rubble, featuring segmentally arched openings with rubble voussoirs and a dripcourse. The roofs vary, with slate used in different styles. The left wing has a central door flanked by a window on either side, and smaller windows set under the eaves for the loft above. The left part has a modern blue slate roof, while the right part has an older purple slate roof.

On the rear elevation, there is a modern boarded door leading to a raking dormer, and a modern brick flat-roofed garage to the right. The central range includes a chimney on the right gable end that serves the former smithy, and the roof is mainly covered with old small slates. The central range features boarded doors and a sequence of narrow windows arranged as DWDWDDW.

The right wing is a three-bay cartshed with a granary above, and it has a lean-to on the right gable end. Its roof is made of small slates, partly grouted, with tiled gabled copings. There are three wide cart openings with segmental stone arches, rubble voussoirs, and dripstones. A stone staircase on the right side leads to a boarded granary door, which slightly breaks above the eaves line. There are two granary windows on the left with modern frames, and two corresponding windows on the rear elevation.

At the right end of the central range, the smithy contains part of a stone and brick hearth, along with a vertical bellows unit on the left.
