L-Plan Range of Farmbuildings at Bryn Cwnin Farm

The L-shaped range of farm buildings at Bryn Cwnin Farm includes a main barn, stabling, and cowhouses, all facing the farmhouse across a yard. These buildings may partially pre-date the house and are likely from the late 18th century. They are constructed of brick with slate roofs, which have been renewed in some areas with corrugated sheeting.

The western range was probably designed as a cowhouse and is built in two phases, featuring two storeys and four bays. On the left side, there are three deep loft doors aligned with lower doorways. Most openings have flat timber lintels, although one lower opening has a cambered brick head. There is a lean-to cart shed against the rear wall. The fourth bay on the right is from a separate phase and has a gabled dormer above the loft entrance, along with a wide segmentally arched opening below that has been infilled to accommodate a separate doorway and window.

This section connects with the main barn, which is positioned at right angles to it. This part of the barn range may have originally served as a cowhouse or stable. It features outer doorways, originally paired on the right, though the inner door is now a window, and square windows on their inner side. There is an inserted doorway and flanking windows at the centre, two loft doors in the upper storey, and cross-shaped vents. All original openings have steep cambered brick heads.

To the right, there is a separate phase that has a wide segmentally arched central doorway, with a similar doorway on the rear elevation, and a single window to the right. There are straight vents in the storage bay to the left, and four loft windows above, two of which retain their original cambered brick heads while the others have been modified. An external staircase provides access to the loft against the rear elevation. Additionally, there are two blocked segmental arches in the eastern gable wall that likely provided access to a separate cart shed in this end bay, similar to an arrangement found in the barn at Rhydyddauddwr Farm in Rhuddlan. Inside, brick and rough timber partitions separate the central bay, with an archway through the brickwork.
