Cornbarn-cowhouse range at Mynachdy

The Cornbarn-cowhouse range at Mynachdy is a long agricultural building dating from the 19th century. It features a taller corn barn on the left and an added cowhouse range on the right, with rectangular stone-walled enclosures likely used as a stack yard at the rear and a cattle yard at the front. The corn barn has well-constructed rubble walls with boulder foundations, prominent corbel stones on the left gable, and three infilled ventilation slits on the right gable. The roof is covered with small slates, partially grouted, while the rear pitch is finished with corrugated asbestos sheeting. There are narrow central opposed doors with ventilation slits on either side; the front doors have been enlarged to serve as windows, while the rear doors remain unaltered.

The cowhouse range on the right has four doors arranged in a sequence of WDWDWDWDW, featuring segmentally arched heads with rubble voussoirs and dripstones. The windows here are either enlargements of earlier openings or newly inserted. The rear wall has three doors, with two at either end leading into lean-tos that have catslide roofs, and a central door leading to the rear yard.

Internally, the corn barn consists of five bays with hewn A-frame roof trusses, which have lightly-built collars pegged to the principals. The cowhouse comprises eight bays with sawn and bolted A-frame roof trusses. The two sections have now been opened into one building, with a stone wall partition at the right end.
