Pointed-arched, trefoil and square-headed window openings some with hood and label mouldings. Oriel window to side elevation with some tracery windows. Cobbled basement area to north-west side with underground passageway to open sunken track. Three blind-arched openings on western side.

Kilronan Castle is an amalgamation of styles from early to late Gothic Revival, reflecting the tastes of the various owners throughout its history. The earlier revived Gothic style section of the house was designed by an unknown architect while the later section was designed by Thomas Newenham Deane. Visually striking on approach, this complex building is embellished by elaborate and intricate features such as the castellated parapet wall and attractive oriel window. The sheer scale and atmosphere combine to make this a captivating house, which is centrally located on the demesne grounds.
