Moulded 3-light mullioned window to left, and 3 mullioned windows on 1st floor, and 2 wooden casements, and C20 bay on ground floor. Interior: the main range appears to be an end-jettied hall house in origin, the end left bay (ie rear to entrance elevation), with smoke-blackened beams and plaster to dividing wall to central bay, but end bay probably a later rebuilding however. Crown post roof the central trussed bays with ogee bracing. Moulded crown post in right end bay, octagonal with capital and base, about 2½ feet high on hollow chamfered and cambered tie beam, the chamfer running out at floor level.

Ground floor rooms with fine double hollow chamfered and fillet moulded beams (moulded mullioned window with hollow chamfer and triple bead). Along the outer rear central walls of this range is probably C14 crenellated and moulded beam with 2 arched service doorways, which may indicate that the surviving range was a cross-wing to en earlier hall, or may be a later insertion (an adjacent bay has been reconstructed late C20 from demolished medieval and C17-C18 buildings). Wainscotting in upper parlour of c.1700. Bricks in left return inscribed: MM '90, Wm Allwork July ..., both c.1800.
