Courtyard range at Brocastle

The courtyard range at Brocastle is a long rectangular two-storey building constructed of coursed rubble with dressed quoins, yellow brick dressings, and a Welsh slate roof featuring decorative bargeboards. It has two slate-hung roof dormers with large casement windows facing the courtyard. The courtyard side has three main bays with cambered-headed openings, where most windows have been replaced, although the original 12-pane window remains at the far right. The barn range, which steps forward to the right, features steps leading to high double boarded doors with an overlight, as well as additional boarded doors. The left gable end has casement windows with timber lintels on the first floor and a cambered arch doorway below that includes a boarded door.

On the drive side, there are unaltered small-pane cambered arched casement windows and a central two-leaved boarded door situated above ground level. Numerous horse ties attached to the masonry indicate that the building may have been used primarily for horses.

The interior includes limewashed stone, with the stable on the left retaining boarded partitions and panelling, as well as a tiled floor. The middle section was formerly a feed store. The area on the right, likely a former feed preparation area, preserves original floors and beams with closely set joists. The ceiling trusses consist of a collar between principal rafters and two rows of trenched purlins.
