Internally the main house probably originally had an L-shaped plan comprising the 2-room front of hall and parlour, with another room behind. The secondary dwelling occupied the other wing to form a coherent, tightly planned block. The original secondary dwelling retains a hall fireplace with timber lintel. The room on the L side of the rear, part of the main house and now and perhaps always a kitchen, retains a fireplace with stop-chamfered stone jambs and lintel. The interior detail is otherwise C19, when plaster ceilings were added concealing the original beams. A straight stair with plain balusters is inside the main entrance in what was probably part of the original hall that was later partitioned. The interior also retains stone-paved floors and C19 boarded and panel doors.

A 2-storey farmhouse of rubble stone with double-pitched slate roof behind coped gabled on moulded kneelers and pebble-dashed ridge stacks. Original mullioned windows are mostly retained and have plain chamfers and simple drip stones. The symmetrical double-gabled front faces S. Its central doorway has a Tudor-headed lintel inscribed '1651 IE', a projecting arched stone canopy, and a C19 panelled door. It is flanked by 3-light mullioned windows, except the window upper R which is replaced by a 3-light wooden casement. Above the doorway is a window replaced in a lintelled opening inserted in the C19. Above the drip stone of the R-hand upper window is a well-preserved stone sundial with gnomon. The R side wall has a 3-light window in the lower storey and 2-light window above it, both offset to the L end. The centre and R comprise the probable secondary dwelling. Its original doorway, with Tudor head and dated inscription similar to the front doorway, is at the R end, but was converted to a window (since replaced) when a doorway under a segmental stone head was inserted immediately L of it in the early C19. This doorway retains a boarded door. Further L, lighting the hall of the secondary dwelling, are 2-light and 3-light windows. The upper storey has three 2-light windows, but without drip stones.

The 3-window L side wall of the house retains 3-light mullioned windows lower centre and upper R, and a 2-light window upper L. The other windows are replaced by 3-light wooden casements, and a doorway is inserted to the L in place of an earlier window. Only the lower-storey windows have drip stones. To the L of centre in the upper storey is a well-preserved stone sundial dated 1734, with gnomon. The rear of the house has two 2-light windows in the upper storey and an added projection below.
