Screen Wall to the service yard at Brynkinallt Hall

The screen wall to the service yard at Brynkinallt Hall is a Grade II listed structure built of brick in a castellated style. It features a symmetrical design with a central gatehouse that includes a 2-centred carriage arch. The mouldings are made of Roman cement, and there is an upper stage situated between round eschaugettes. The parapet and crenellations are supported by simulated stone corbels, and there are thin flanking brick buttresses. Above the gate, the Trevor arms are displayed.

The side walls are adorned with stone-framed timber mullioned and transomed windows, each with label hoods, as well as a pointed-arched door. These walls are topped with a parapet on a corbel table and extend to square terminal towers. Each tower features two leaded light windows and decorative quatrefoil motifs beneath the crenellated parapets. The lowest part of the western wall and tower is constructed of sandstone, indicating the incorporation of an earlier structure. At the rear, lean-to service buildings, including dog kennels, are arranged along the yard face.
