House comprises 3-unit main range with two added wings. Main range originally comprised 2-bay open hall with inner room beyond dais partition at upper (west end), and probably paired service rooms to east (later remodelled as a parlour). entrance passage to rear of inserted hall stack: deep stop chamfered beam to passage ceiling continues over the basement staircase which is separated from the entrance hall by a stud partition. A further deep chamfered beam runs parallel from the front line of the stack to the partition that formerly defined the lower end of the hall. Both these (with their associated joists) are C16 in character. Inserted staircase (probably C18) against rear wall of former hall, just offset from the entrance passage. Hall has inserted fireplace with chamfered bressumer. Paired axial ceiling beams and thin chamfered joists appear to be later than the deep-chamfered cross-beam which probably marks the position of the original partition at the upper (dais) end of the hall. Set back behind this is a square-panelled timber-framed partition, thought now to be an insertion (perhaps of the C16?). Beyond this is the original upper room, now containing the remains of slate slabs from its re-use as a service room associated with the kitchen in the added wing. This wing has a gable fireplace, partially collapsed on inspection; ceiling also partially collapsed, though deep-chamfered beam survived in situ. The box-framed partitions that mark the extent of the original hall survive substantially intact, with heavy posts carrying tie beam (above the level of the present ceiling), and queen-posts to collars. Evidence for paired doorways said to be visible in lower partition. Central hall truss also survives, a highly unusual example of an arch-braced base-cruck, with high-set collar. Parlour end of house below the entrance passage has 2 parallel cross-beams with deep chamfers, and fireplace with stone jambs and timber bressumer; the stack serves the NE wing also (not inspected): perhaps the lower end of the main range, was substantially rebuilt when this wing was added.

Main range built on a platformed site against the slope, and oriented roughly east-west, with two parallel wings on the north elevation. One and a half storeyed, but with basement storey below the eastern end. Render over rubble, retaining traces of graded slate roofs to wings, the main range re-roofed (probably in the late C19) in machine-cut slate. Axial stack in main range, and gable end stack to NW wing, both rebuilt in the later C19, perhaps contemporary with re-roofing. Entrance in S elevation, with small casement window to its right. Larger 3-light wood mullioned and transomed window with some surviving leading to hall to left. 2 raking dormers in the roof-slope above. East gable end is 3 storeyed, with doorway to basement floor, and 3-light window on each floor above. These have canopy hoods carried on brackets. Date stone in gable apex (1727 with initials £ over Ll). NE gable has 3-light casement window with similar hood, and 3-light dormer window above. Rear doorway to main range between the two wings. NW wing has doorway in angle with main range, and 2-light window with canopy hood. The 2-light window above retains some leading. Offset doorway to first floor in gable end, and 3-light window in rear elevation.
