Ruined castle of rubble stone comprising a 2-storey hall range oriented N-S (consisting of undercroft and 1st-floor hall), with the remains of a wing attached to W side, a 2-stage tower at S end of hall, to which a stable wing is attached to E. On W side is remains of a faceted curtain wall forming a rough D-shape in plan.
The tower is slightly narrower than the hall range and is set back from its W wall. It has, in its S wall, a small stair light L and a large opening to centre in the upper stage, with putlog holes to R. In the E wall is a central segmental-headed opening in the upper stage (with voussoirs missing). In the W wall are 2 small stair lights to R and the curtain wall attached to the SW angle. The tower is entered in N wall to R, from the undercroft to the hall, and leads to remains of a mural stair. The tower has a vaulted undercroft entered from the hall range through a 2-centred doorway with stop-chamfer surround. At the top of the stairs is one stop-chamfered jamb of a doorway leading into the upper chamber. The upper chamber has a garderobe in the NE corner entered through a doorway with remains of a triangular head. In the N wall a doorway is cut through to hall to R and in centre is a single corbel of a possible former corbelled external stack to hall. In the W wall is a narrow doorway with a lancet head giving access to stone steps R and L up to a former wall walk on the curtain wall.
The W wall of the hall range has an inserted doorway R with window above. To the L is a similar 1st-floor window with a blocked doorway below (visible only inside). The ground is banked up against the E wall, where there is one upper-storey window (lower storey openings are visible only inside the building). The original entrance to the hall range was at the N end of the W wall, where the wing was later added. The jambs of outer and inner arches survive of this original doorway, and have wave-moulded chamfers and haunches of Tudor arches. The doorway originally led to stairs to the 1st-floor hall and to the R of the doorway is a cross wall in the undercroft, which has a fireplace with a segmental head and an infilled hearth. Above it is a single moulded corbel, and to its R is a Tudor-headed doorway leading up to the hall. One jamb of the doorway into the hall is above and to L of the fireplace. A later fireplace is inserted into the E wall of the undercroft, to the R of which is a blocked window.
In the S wall of the hall is a fine Tudor-Gothic chimneypiece, with remains of a Tudor head, and with filleted jambs carried up as shafts with foliage trails in hollow chamfers above the fireplace to support a former shelf. To the L of fireplace is the doorway to the tower.
The wing has, in the S wall, an inserted doorway to L with brick jambs (later blocked), a similar blocked doorway to the R with segmental brick head, and a window upper R. In the W gable end is an inserted window upper centre with brick jambs and a segmental head, blocked with stone. To the L are openings in a former outshut, consisting of a wide doorway (with one jamb repaired in brick) and a small opening above in a dressed stone surround. In the N wall of the wing are chamfered jambs of a doorway to the R at low level, the doorway now blocked with stone.
The stable has a 4-window S wall (now detached from tower). A doorway to the R has segmental head, former doorways to the L and R of centre are converted to windows (with brick head to L). The window L of centre is narrowed in a brick surround. The windows to the R in the upper storey have brick heads, and a window L of centre is blocked. The ground level built up against the gable end and the rear.
The curtain wall is ruinous and discontinuous, and has C19 battlements.
