Farm building at Bryn coch cottage

The farm building at Bryn Coch Cottage is a timber-framed structure dating from the early 17th century. It is clad in red painted corrugated iron and has a random slate roof. The building consists of four bays, with a lean-to at the lower end. There is one timber door in the upper bay, a stable door in the third bay, and a pitching hatch in the end bay. The footings have been strengthened with concrete.

Each bay is stepped up, featuring five slender cruck trusses that likely date from the early 17th century. These trusses have halved-in and pegged ties and collars, with the ties tenoned to the wall plate. The apex is joined by a yoke at the centre couple and upper end. There is one tier of purlins, which were originally lodged on the extended collars but have since been replaced by a stub tie and outriding rafter construction that now supports the purlins. All trusses appear to have originally been filled to tie level, and an original ground sill survives at the lower end. The walls consist of two panels high, made of square framing.
