Cowhouse at Pen-hefyd Farm

The Cowhouse at Pen-hefyd Farm is a designed estate building typical of model farms, built in the 19th century. It features a lofted double-pile plan, with a range constructed from rubble and hammer-dressed quoins, along with similar window and door dressings. Notable characteristics include its parallel half-hipped slate roofs and thermal windows at both the north and south ends, with overhanging eaves that sweep out to the outer edges. The rounded jambs of the doorways are designed to prevent injury to cattle moving in and out.

The south end of the building faces the farmyard and has a central entrance leading to a longitudinal passage, while the north end, which is closer to the fields, has two entrances at the extreme left and right, along with a central window. The side elevations have three windows each, featuring voussoirs above square-headed openings, and the upper parts of the windows are slatted. The yard elevation includes cart doors and two rooflights.

Inside, the whitewashed brick retains the original layout intended for tethering cattle facing the central passage. Full-width tie beams support each pair of trusses in the simple six-bay, purlined roof. The building was converted into an estate workshop in the 1990s, which involved some minor changes.
