The castle takes the form of a Z-plan tower house and most likely incorporates an earlier tower in its eastern side. The rectangular main block measures 43 by 27 feet (13.1 by 8.2 m) and is three storeys and an attic high. Circular bartizans are corbelled out at the north and south corners at the second-storey level. Four-storey round towers, roughly 23 feet (7.0 m) in diameter, are at the northwestern and southeastern corners. Circular stair towers are corbelled out at the first-storey level at the northern junctures with the main block.[1][2]
The interior and the roofs were remodelled around 1790. Sometime during the 18th or 19th century a two-storey porch and stairway was built against the northern face of the castle. A single-storey U-plan corrugated-iron structure was erected in 1870 on the eastern side, probably as an office. In the early 20th century a five-storey addition was built, completely enclosing the southeastern tower. The castle fell into a state of dereliction by the 1960s, but it was renovated for use as a private family home from about 1968–1998 by a series of owners. As part of the remodelling, all of the external additions, except for the office, were demolished.
