Description
The cow house at Trefaes is a structure made up of two ranges positioned end-to-end on a sloping site, separated by a full-height vertical joint. Both sections are built from roughly coursed field-stone. The upper section, which is the earlier of the two, features a higher corrugated metal roof behind coped gables. The lower section has a graded slate roof and includes a split boarded door on the left, with a central former doorway that has been infilled and now contains an inserted hopper window. The rear of this section has three ventilation strips, and the downhill gable end has a loft opening.
In the upper section, there is a boarded door on the right, along with a later projection made of rubble stone that has a single-pitch roof of corrugated metal. This projection is open at the front and supported by wooden posts, which are further reinforced by two brick piers.
